The proper management of subepithelial lesions (SELs) depends on the size, histopathology, malignant potential, and presence of symptoms, according to a new American Gastroenterological Association clinical practice update published in Clinical Gastroenterology and Hepatology.

“SELs are found in 1 in every 300 endoscopies, and two-thirds of these lesions are located in the stomach,” explained Kaveh Sharzehi, MD, an associate professor of medicine in the division of gastroenterology and hepatology at Oregon Health & Science University, Portland, and colleagues. “They represent a heterogeneous group of lesions including nonneoplastic lesions such as ectopic pancreatic tissue and neoplastic lesions. The neoplastic SELs can vary from lesions with no malignant potential such as lipomas to those with malignant potential such as gastrointestinal stromal tumors (GISTs). The majority of SELs are small and found incidentally.”

The authors developed 10 clinical practice advice statements on the diagnosis and management of subepithelial lesions based on a review of the published literature and expert opinion.

First, standard mucosal biopsies often don’t reach deep enough to obtain a pathologic diagnosis for SELs because the lesions have normal overlying mucosa. Forceps bite-on-bite/deep-well biopsies or tunnel biopsies may help to establish a pathologic diagnosis.

Used as an adjunct to standard endoscopy, endoscopic ultrasound (EUS) has become the primary method for determining diagnostic and prognostic characteristics of SELs – such as the layer of origin, echogenicity, and presence of blood vessels within the lesion. It can also help with tissue acquisition.

For SELs arising from the submucosa, EUS-guided fine-needle aspiration and fine-needle biopsy have evolved as widely used methods for obtaining tissue. For SELs arising from muscularis propria, fine-needle aspiration and fine-needle biopsy should be used to determine whether the lesion is a GIST or leiomyoma. Using structural assessment and staining will allow for the differentiation of mesenchymal tumors and assessment of their malignant potential.

To remove SELs, multiple endoscopic resection techniques may be appropriate, depending on the layer of origin, size, and location, with the goal of complete, en bloc resection with no disruption to the wall or capsule of the lesion. These techniques should be limited to endoscopists skilled in advanced tissue resection.

SELs without malignant potential, such as lipoma or pancreatic rest, don’t need further evaluation or surveillance.

SELs that are ulcerated, bleeding, or causing symptoms should be considered for resection.

Other lesions are managed with resection or surveillance based on pathology. For example, leiomyomas, which are benign and most often found in the esophagus, generally don’t require surveillance or resection. On the other hand, all GISTs have some malignant potential, and management varies by size, location, and presence of symptoms. GISTs larger than 2 cm, should be considered for resection. Some GISTs between 2 cm and 4 cm without high-risk features can be removed by using advanced endoscopic resection techniques.

The determination for resection in all cases should include a multidisciplinary approach, with confirmation of a low mitotic index and lack of metastatic disease on cross-sectional imaging.

“The ultimate goal of endoscopic resection is to have a complete resection,” the authors wrote. “Determining the layer of involvement by EUS is critical in planning resection techniques.”

Segmental neurofibromatosis, or neurofibromatosis type 5 (NF5), is a rare subtype of neurofibromatosis type 1 (NF1)(also known as von Recklinghausen disease). Phenotypic manifestations of NF5 include café-au-lait macules, neurofibromas, or both in 1 or more adjacent dermatomes. In contrast to the systemic features of NF1, the dermatomal distribution of NF5 demonstrates mosaicism due to a spontaneous postzygotic mutation in the neurofibromin 1 gene, NF1. We describe an atypical presentation of NF5 with bilateral features on the upper extremities.

A 74-year-old woman presented with soft pink- to flesh-colored growths on the left dorsal forearm and hand that were observed incidentally during a Mohs procedure for treatment of a basal cell carcinoma on the upper cutaneous lip. The patient reported that the lesions initially appeared on the left dorsal hand at approximately 16 years of age and had since spread proximally up to the mid dorsal forearm over the course of her lifetime. She denied any pain but claimed the affected area could be itchy. The lesions did not interfere with her daily activities, but they negatively impacted her social life due to their cosmetic appearance as well as her fear that they could be contagious. She denied any family history of NF1.

Physical examination revealed innumerable soft, pink- to flesh-colored cutaneous nodules ranging from 3 to 9 mm in diameter clustered uniformly on the left dorsal hand and lower forearm within the C6, C7, and C8 dermatomal regions (Figure, A). A singular brown patch measuring 20 mm in diameter also was observed on the right dorsal hand within the C6 dermatome, which the patient reported had been present since birth (Figure, B). The nodules and pigmented patch were clinically diagnosed as cutaneous neurofibromas on the left arm and a café-au-lait macule on the right arm, each manifesting within the C6 dermatome on separate upper extremities. Lisch nodules, axillary freckling, and acoustic schwannomas were not observed. Because of the dermatomal distribution of the lesions and lack of family history of NF1, a diagnosis of bilateral NF5 was made. The patient stated she had declined treatment of the neurofibromas from her referring general dermatologist due to possible risk for recurrence.

Segmental neurofibromatosis was first described in 1931 by Gammel,¹ and in 1982, segmental neurofibromatosis was classified as NF5 by Riccardi.² After Tinschert et al³ later demonstrated NF5 to be a somatic mutation of NF1,³ Ruggieri and Huson⁴ proposed the term mosaic neurofibromatosis 1 in 2001.

While the prevalence of NF1 is 1 in 3000 individuals,⁵ NF5 is rare with an occurrence of 1 in 40,000.⁶ In NF5, a spontaneous NF1 gene mutation occurs on chromosome 17 in a dividing cell after conception.⁷ Individuals with NF5 are born mosaic with 2 genotypes—one normal and one abnormal—for the NF1 gene.⁸ This contrasts with the autosomal-dominant and systemic characteristics of NF1, which has the NF1 gene mutation in all cells. Patients with NF5 generally are not expected to have affected offspring because the spontaneous mutation usually arises in somatic cells; however, a postzygotic mutation in the gonadal region could potentially affect germline cells, resulting in vertical transmission, with documented cases of offspring with systemic NF1.⁴ Because of the risk for malignancy with systemic neurofibromatosis, early diagnosis with genetic counseling is imperative in patients with both NF1 and NF5.

Neurofibromatosis type 5 is a clinical diagnosis based on the presence of neurofibromas and/or café-au-lait macules in a dermatomal distribution. The clinical presentation depends on when and where the NF1 gene mutation occurs in utero as cells multiply, differentiate, and migrate.⁸ Earlier mutations result in a broader manifestation of NF5 in comparison to late mutations, which have more localized features. An NF1 gene mutation causes a loss of function of neurofibromin, a tumor suppressor protein, in Schwann cells and fibroblasts.⁸ This produces neurofibromas and café-au-lait macules, respectively.⁸

A large literature review on segmental neurofibromatosis by Garcia-Romero et al⁶ identified 320 individuals who did not meet full inclusion criteria for NF1 between 1977 and 2012. Overall, 76% of cases were unilaterally distributed. The investigators identified 157 individual case reports in which the most to least common presentation was pigmentary changes only, neurofibromas only, mixed pigmentary changes with neurofibromas, and plexiform neurofibromas only; however, many of these cases were children who may have later developed both neurofibromas and pigmentary changes during puberty.⁶ Additional features of NF5 may include freckling, Lisch nodules, optic gliomas, malignant peripheral nerve sheath tumors, skeletal abnormalities, precocious puberty, vascular malformations, hypertension, seizures, and/or learning difficulties based on the affected anatomy.

Segmental neurofibromatosis, or NF5, is a rare subtype of NF1. Our case demonstrates an unusual bilateral distribution of NF5 with cutaneous neurofibromas and a café-au-lait macule on the upper extremities. Awareness of variations of neurofibromatosis and their genetic implications is essential in establishing earlier clinical diagnoses in cases with subtle manifestations.

Until the second half of the 20th century, it was believed that the uterine cavity was sterile. Since then, technological advances have provided insight into the nature of the microbiome throughout the female reproductive tract. The role of these microorganisms on the fertility of women of reproductive age has been the subject of research. Is there an “optimal microbiome” for fertility? Can changing the microbiome of the uterine cavity affect fertility? There is still no definitive scientific response to these questions.

Several studies describe the healthy state of the uterine microbiota in women of reproductive age, with most of these studies reporting dominance of Lactobacillus species. However, by contrast, some studies did not observe Lactobacillus predominance inside the uterine cavity in cases of healthy uterine microbiomes. The presence of other microorganisms, such as Gardnerella vaginalis, was associated with reduced success in patients attempting in vitro fertilization (IVF) treatment, such as, for example, embryo implantation failure and miscarriage.

It is also possible that a physiologic endometrial microbiome could be considered healthy despite a minor presence of pathogenic bacteria. Importantly, responses from the host also modulate many aspects of human conception. These shifts correlate with parameters such as age, hormonal changes, ethnicity, sexual activity, and intrauterine devices.

Carlos Simón, MD, PhD, is a gynecologist and obstetrician and professor at the University of Valencia in Valencia, Spain; Harvard University, Cambridge, Mass.; and Baylor College of Medicine, Houston. He was in São Paulo at the time of the XXVI Brazilian Congress of Assisted Reproduction and agreed to be interviewed by Medscape Portuguese Edition. Dr. Simón, who is Spanish and is an international reference in uterine microbiome studies, created an endometrial receptivity analysis (ERA).

“What we know is that the human uterus has its own microbiome. Thanks to next-generation sequencing (NGS), we can detect microbial DNA. We’re talking about a microbiome that, if changed, affects [embryo] implantation. We have identified that Lactobacilli are the good [microorganisms], but if there are Streptococci, Gardnerella, or other bacteria, the implantation [of the embryo] is affected.”

In 2018, Dr. Simón’s team published a pilot study assessing the microbiome of 30 patients during fertilization treatment. It was observed that, when there is a change in the microbiome, the implantation rate drops to half and the miscarriage rate doubles.

Following this study, also in 2018, the team published a multicenter, prospective, observational study. A 16S ribosomal RNA (16S rRNA) gene sequencing technique was used to analyze endometrial fluid and biopsy samples before embryo transfer in a cohort of 342 infertile patients asymptomatic for infection. Participants underwent fertilization procedures in 13 centers on three continents.

A dysbiotic endometrial microbiota profile composed of Atopobium, Bifidobacterium, Chryseobacterium, Gardnerella, Haemophilus, Klebsiella, Neisseria, Staphylococcus, and Streptococcus was associated with unsuccessful outcomes. In contrast, Lactobacillus was consistently enriched in patients with live birth outcomes. The authors concluded that endometrial microbiota composition before embryo transfer is a useful biomarker to predict reproductive outcome.

“You see a microbial signature in patients who become pregnant, another in those who do not become pregnant, and yet another in those who miscarry,” Dr. Simón summarized. “By knowing this signature, the microbiome can be analyzed and treated so that it is stabilized before the embryo is transferred.”
 

What should be done?

Endometrial microbiome profiles do not use microbial cultures. They are obtained by NGS of the endometrial sample. This is because the 16S rRNA gene, which can be found in bacteria, presents hypervariable regions that serve as markers to identify the bacteria present.

If a microbiome is found to be somewhat unhealthy, it is theoretically possible to change its composition, increasing the chances of successful assisted reproduction. The administration of antibiotics and vaginal probiotics are two treatment approaches.

According to Dr. Simón, treatment is specific to the bacterium (metronidazole, and, if that fails, rifampicin for Gardnerella, amoxicillin and clavulanic acid for Streptococci). Once the pathogenic bacterium has been treated, the probiotics can be administered. “If all is well, we can then go ahead with the procedure,” he explained.

Dr. Simón pointed out that, with respect to treatment, knowledge is still limited and primarily based on case reports. “You look for issues in the microbiome when the patient experiences reproductive failure and there are no other causes,” he emphasized. “Microbiology plays a role in reproduction, affecting the human uterus. It’s good to know about it to improve reproductive outcomes. When there are repeated [embryo] implantation failures, we suggest an endometrial biopsy to identify the implantation window and determine whether the uterine microbiome is healthy or not. And if there are any abnormalities in the microbiome, they can be treated.”

There are still many open questions, such as how long the “good microbiome” lasts after antibiotic therapy. “We suggest checking the microbiome after [antibiotic] treatment and before implanting the embryo,” said Dr. Simón.

Although there is no consensus on how the endometrial microbiota relate to reproductive outcomes, the analysis and change in microbiome are already being offered in clinical practice as a way to increase the chances of conception. Márcia Riboldi, PhD, a genetics specialist serving as Country Manager for Igenomix Brasil and Argentina, the company that offers the analyses, provides an idea of the market for such analyses in Brazil. “We perform approximately 500 analyses per month,” she said, adding that most patients have a history of [embryo] implantation failure or miscarriage.

Matheus Roque, MD, PhD, an IVF specialist, shared two IVF case reports from the Mater Prime Human Reproduction Clinic in the southern region of the city of São Paulo. He emphasized that the decision to perform a microbiome analysis was made only after repeated implantation failure.

“With the outcomes the doctors started to see, the paradigm started to shift,” said Dr. Riboldi. “Why wait for the patient to have [an embryo] transfer failure? Let’s study the endometrium, check the ideal moment for the transfer, see whether it’s receptive or not, if there’s any disease and if there are Lactobacilli,” she proposed. “We need medical training and awareness, and we need to use them appropriately. We have the tests. Doctors need to learn about them and know when and how to use them.” The microbiome analysis costs approximately BRL 2,000, plus expenses for the medical procedure.
 

Is it too early?

Caio Parente Barbosa, MD, PhD, is an obstetrician/gynecologist specializing in human reproduction, as well as the director general and founder of the Fertile Idea Institute for Reproductive Health. He shared a few of his experiences in an interview with this news organization. “I would say it is still too early to confirm that [the microbiome analysis] produces effective outcomes.”

Dr. Barbosa, who is also provost of graduate studies, research, and innovation of the ABC School of Medicine, Santo André, Brazil, emphasized there is still little global experience with these analyses. “There are doubts worldwide regarding whether these analyses produce effective outcomes. Scientific studies are entirely controversial.”

He stated that some professionals recommend the microbiome analysis for “patients who don’t know what else to do,” but also recognized that there is already a demand for patients who don’t fit this category, who research the analyses on social networks and YouTube. “But it is the smallest of demands. Patients are not as worried about this yet.”

Dr. Barbosa recognized that the idea of an increasingly tailored treatment plan is inevitable. He believes that the study and treatment of the microbiome will become more critical in the future, but he thinks it still “does not offer any value.”

Dr. Barbosa emphasized that the financial side of things must also be considered. “If we add all these tests when investigating a patient’s issues, the treatment becomes ridiculously expensive.” He pointed out that health care professionals need to be careful to perform minimal testing. “We have already added some tests, such as the karyotype test, to the minimal testing for all patients.”

Dr. Simón responded to this criticism, stating: “The cost of repeating cycles is always greater than that of being thorough and knowing what’s going on. Nothing is certain, but if my daughter or wife needed it, I would like to have as much information as possible to make this decision.”

Dr. Barbosa and Dr. Simón reported no relevant financial relationships. Dr. Riboldi is Country Manager for Igenomix Brasil and Argentina, the company that offers the analyses.

Importantly, responses from the host also modulate many aspects of human conception. These shifts correlate with parameters such as age, hormonal changes, ethnicity, sexual activity, and intrauterine devices.

Carlos Simón, MD, PhD, is a gynecologist and obstetrician and professor at the University of Valencia in Valencia, Spain; Harvard University, Cambridge, Mass.; and Baylor College of Medicine, Houston. He was in São Paulo at the time of the XXVI Brazilian Congress of Assisted Reproduction and agreed to be interviewed by Medscape Portuguese Edition. Dr. Simón, who is Spanish and is an international reference in uterine microbiome studies, created an endometrial receptivity analysis (ERA).

“What we know is that the human uterus has its own microbiome. Thanks to next-generation sequencing (NGS), we can detect microbial DNA. We’re talking about a microbiome that, if changed, affects [embryo] implantation. We have identified that Lactobacilli are the good [microorganisms], but if there are Streptococci, Gardnerella, or other bacteria, the implantation [of the embryo] is affected.”

In 2018, Dr. Simón’s team published a pilot study assessing the microbiome of 30 patients during fertilization treatment. It was observed that, when there is a change in the microbiome, the implantation rate drops to half and the miscarriage rate doubles.

Following this study, also in 2018, the team published a multicenter, prospective, observational study. A 16S ribosomal RNA (16S rRNA) gene sequencing technique was used to analyze endometrial fluid and biopsy samples before embryo transfer in a cohort of 342 infertile patients asymptomatic for infection. Participants underwent fertilization procedures in 13 centers on three continents.

A dysbiotic endometrial microbiota profile composed of Atopobium, Bifidobacterium, Chryseobacterium, Gardnerella, Haemophilus, Klebsiella, Neisseria, Staphylococcus, and Streptococcus was associated with unsuccessful outcomes. In contrast, Lactobacillus was consistently enriched in patients with live birth outcomes. The authors concluded that endometrial microbiota composition before embryo transfer is a useful biomarker to predict reproductive outcome.

“You see a microbial signature in patients who become pregnant, another in those who do not become pregnant, and yet another in those who miscarry,” Dr. Simón summarized. “By knowing this signature, the microbiome can be analyzed and treated so that it is stabilized before the embryo is transferred.”
 

What should be done?

Endometrial microbiome profiles do not use microbial cultures. They are obtained by NGS of the endometrial sample. This is because the 16S rRNA gene, which can be found in bacteria, presents hypervariable regions that serve as markers to identify the bacteria present.

If a microbiome is found to be somewhat unhealthy, it is theoretically possible to change its composition, increasing the chances of successful assisted reproduction. The administration of antibiotics and vaginal probiotics are two treatment approaches.

According to Dr. Simón, treatment is specific to the bacterium (metronidazole, and, if that fails, rifampicin for Gardnerella, amoxicillin and clavulanic acid for Streptococci). Once the pathogenic bacterium has been treated, the probiotics can be administered. “If all is well, we can then go ahead with the procedure,” he explained.

Dr. Simón pointed out that, with respect to treatment, knowledge is still limited and primarily based on case reports. “You look for issues in the microbiome when the patient experiences reproductive failure and there are no other causes,” he emphasized. “Microbiology plays a role in reproduction, affecting the human uterus. It’s good to know about it to improve reproductive outcomes. When there are repeated [embryo] implantation failures, we suggest an endometrial biopsy to identify the implantation window and determine whether the uterine microbiome is healthy or not. And if there are any abnormalities in the microbiome, they can be treated.”

There are still many open questions, such as how long the “good microbiome” lasts after antibiotic therapy. “We suggest checking the microbiome after [antibiotic] treatment and before implanting the embryo,” said Dr. Simón.

Although there is no consensus on how the endometrial microbiota relate to reproductive outcomes, the analysis and change in microbiome are already being offered in clinical practice as a way to increase the chances of conception. Márcia Riboldi, PhD, a genetics specialist serving as Country Manager for Igenomix Brasil and Argentina, the company that offers the analyses, provides an idea of the market for such analyses in Brazil. “We perform approximately 500 analyses per month,” she said, adding that most patients have a history of [embryo] implantation failure or miscarriage.

Matheus Roque, MD, PhD, an IVF specialist, shared two IVF case reports from the Mater Prime Human Reproduction Clinic in the southern region of the city of São Paulo. He emphasized that the decision to perform a microbiome analysis was made only after repeated implantation failure.

“With the outcomes the doctors started to see, the paradigm started to shift,” said Dr. Riboldi. “Why wait for the patient to have [an embryo] transfer failure? Let’s study the endometrium, check the ideal moment for the transfer, see whether it’s receptive or not, if there’s any disease and if there are Lactobacilli,” she proposed. “We need medical training and awareness, and we need to use them appropriately. We have the tests. Doctors need to learn about them and know when and how to use them.” The microbiome analysis costs approximately BRL 2,000, plus expenses for the medical procedure.
 

Is it too early?

Caio Parente Barbosa, MD, PhD, is an obstetrician/gynecologist specializing in human reproduction, as well as the director general and founder of the Fertile Idea Institute for Reproductive Health. He shared a few of his experiences in an interview with this news organization. “I would say it is still too early to confirm that [the microbiome analysis] produces effective outcomes.”

Dr. Barbosa, who is also provost of graduate studies, research, and innovation of the ABC School of Medicine, Santo André, Brazil, emphasized there is still little global experience with these analyses. “There are doubts worldwide regarding whether these analyses produce effective outcomes. Scientific studies are entirely controversial.”

He stated that some professionals recommend the microbiome analysis for “patients who don’t know what else to do,” but also recognized that there is already a demand for patients who don’t fit this category, who research the analyses on social networks and YouTube. “But it is the smallest of demands. Patients are not as worried about this yet.”

Dr. Barbosa recognized that the idea of an increasingly tailored treatment plan is inevitable. He believes that the study and treatment of the microbiome will become more critical in the future, but he thinks it still “does not offer any value.”

Dr. Barbosa emphasized that the financial side of things must also be considered. “If we add all these tests when investigating a patient’s issues, the treatment becomes ridiculously expensive.” He pointed out that health care professionals need to be careful to perform minimal testing. “We have already added some tests, such as the karyotype test, to the minimal testing for all patients.”

Dr. Simón responded to this criticism, stating: “The cost of repeating cycles is always greater than that of being thorough and knowing what’s going on. Nothing is certain, but if my daughter or wife needed it, I would like to have as much information as possible to make this decision.”

Dr. Barbosa and Dr. Simón reported no relevant financial relationships. Dr. Riboldi is Country Manager for Igenomix Brasil and Argentina, the company that offers the analyses.

Until the second half of the 20th century, it was believed that the uterine cavity was sterile. Since then, technological advances have provided insight into the nature of the microbiome throughout the female reproductive tract. The role of these microorganisms on the fertility of women of reproductive age has been the subject of research. Is there an “optimal microbiome” for fertility? Can changing the microbiome of the uterine cavity affect fertility? There is still no definitive scientific response to these questions.

Several studies describe the healthy state of the uterine microbiota in women of reproductive age, with most of these studies reporting dominance of Lactobacillus species. However, by contrast, some studies did not observe Lactobacillus predominance inside the uterine cavity in cases of healthy uterine microbiomes. The presence of other microorganisms, such as Gardnerella vaginalis, was associated with reduced success in patients attempting in vitro fertilization (IVF) treatment, such as, for example, embryo implantation failure and miscarriage.

It is also possible that a physiologic endometrial microbiome could be considered healthy despite a minor presence of pathogenic bacteria.

Fecal microbiota transplantation (FMT) is safe and highly effective as first-line therapy for patients with first or second Clostridioides difficile infection, according to the first randomized, double-blind, placebo-controlled trial of its kind.

Study enrollment was halted after an interim analysis revealed significantly better outcomes among patients who received vancomycin plus FMT versus vancomycin alone, reported lead author Simon Mark Dahl Baunwall, MD, of Aarhus (Denmark) University Hospital and colleagues in The Lancet Gastroenterology & Hepatology.

The investigators noted that the participants represented a real-world patient population, so the data support FMT “as a necessary, effective first-line option” in routine management of C. difficile infection.

“Previous studies have demonstrated clinical cure rates [with FMT] of up to 92%,” Dr. Baunwall and colleagues wrote. “Early use of FMT for first or second C. difficile infection has therapeutic potential, but no formal randomized trials to support use of the approach as a first-line therapy have been done.”

The present trial, conducted at a university hospital in Denmark, involved 42 adult patients with first or second C. difficile infection. Patients were randomized in a 1:1 ratio to receive either vancomycin alone or vancomycin plus FMT. All patients received 125 mg oral vancomycin four times daily for a minimum of 10 days after diagnosis. On day 1 after completion of vancomycin therapy and again between day 3 and 7, patients received either oral FMT or matching placebo, depending on their group. After completing the protocol, patients were followed for 8 weeks or C. difficile recurrence to evaluate resolution of C. difficile–associated diarrhea.

“In this trial, patients were treated with two sequential FMT procedures on separate days,” the investigators noted. “This practice might have overtreated some patients and differs from previous trials. It remains unknown whether optimal effect is achieved by one or two treatments.”

The trial design called for 84 patients, but enrollment was halted after an interim analysis of the above cohort of 42 patients because of significantly lower rate resolution in the placebo group. At the 2-month mark, 90% (95% confidence interval, 70%-99%) of patients in the FMT group had resolution, compared with only 33% (95% CI, 15%-57%) of patients in the placebo group (P = .0003), constituting a 57% (95% CI, 33%-81%) absolute risk reduction.

Most patients experienced adverse events, including 20 in the FMT group and all 21 in the placebo group, although most were transient and nonserious. The most common adverse events were diarrhea, which occurred more frequently in the FMT group (23 vs. 14 events), followed by abdominal pain(14 vs. 11 events) and nausea (12 vs. 5 events).

One limitation of the study was its single-center design with regional uptake; the authors noted that, despite having high statistical power for the clinical effect, the study’s premature termination and low patient number prevent inferences regarding mortality, time to effect, and cost.

“The results of this trial highlight how the use of fecal microbiota transplantation as a first-line treatment can effectively prevent C. difficile recurrence and suggests that microbiota restoration might be necessary to obtain sustained resolution,” the investigators wrote. “At present, only 10% of patients with multiple, recurrent C. difficile infection and indication for FMT receive it. International initiatives address the unmet need, but logistic and regulatory obstacles remain unsolved.”
 

Encouraging findings, lingering concerns

Nicholas Turner, MD, assistant professor in the division of infectious diseases at Duke University, Durham, N.C., praised the study for “pushing the boundaries for FMT,” and noted that the methodology appeared sound. Results in the placebo group, however, cast doubt on the generalizability of the findings, he said.

“If you look at the group that received vancomycin plus placebo, their failure rate was really astoundingly high,” Dr. Turner said in an interview, referring to the 67% failure rate in the control group; he noted previous studies had reported failure rates closer to 10%. “I think that just calls into question just a little bit what happened with that control group.”

Dr. Turner said his confidence would go “way, way up” if the findings were reproduced in a larger study. Ideally, these future trials would use fidaxomicin, he added, which is becoming the preferred option over vancomycin for treating C. difficile.

John Y. Kao, MD, professor of medicine and codirector of the FMT program at University of Michigan Medicine, Ann Arbor, offered a different perspective, suggesting that the control group findings shouldn’t overshadow the efficacy of FMT.

“I agree that historical data would tell us that the placebo population should see a much higher response,” Dr. Kao said in an interview. “In my mind though, the success rate of FMT over placebo is what I would expect. The message of the study should be upheld: that FMT is an effective therapy whether it’s given early or, as the way we give it now, as a sort of rescue therapy.”

Despite this confidence in FMT as an efficacious first-line option, Dr. Kao said it is unlikely to be routinely used in this way anytime soon, even if a larger trial echoes the present results.

“We don’t know the long-term risks of FMT therapy, although we’ve been doing this now probably close to 20 years,” Dr. Kao said.

Specifically, Dr. Kao was most concerned about the long-term risk of colon cancer, as mouse models suggest that microbiome characteristics may affect risk level, and risk may vary based on host-microbiome relationships. In other words, an organism may pose no risk in the gut of the donor, but the same may not be true for the recipient.

While increased rates of colon cancer or other serious illnesses have not been detected in humans who have undergone FMT over the past 2 decades, Dr. Kao said that these findings cannot be extrapolated over a patient’s entire lifetime, especially for younger individuals.

“In a patient that’s 80, you would say, yeah, let’s go ahead and treat you [with FMT] as first-line therapy, whereas someone who’s 20, and has maybe another 50 or 60 years longevity, you may not want to give FMT as first-line therapy,” Dr. Kao said.

This study was supported by Innovation Fund Denmark. The investigators disclosed no competing interests. Dr. Turner previously performed statistical analyses for a Merck study comparing vancomycin, fidaxomicin, and metronidazole for C. difficile infection. Dr. Kao disclosed no relevant conflicts of interest.

“In a patient that’s 80, you would say, yeah, let’s go ahead and treat you [with FMT] as first-line therapy, whereas someone who’s 20, and has maybe another 50 or 60 years longevity, you may not want to give FMT as first-line therapy,” Dr. Kao said.

This study was supported by Innovation Fund Denmark. The investigators disclosed no competing interests. Dr. Turner previously performed statistical analyses for a Merck study comparing vancomycin, fidaxomicin, and metronidazole for C. difficile infection. Dr. Kao disclosed no relevant conflicts of interest.

Vedolizumab is an innovative monoclonal antibody targeted against the α4β7 integrin that is approved for treatment of moderate to severe ulcerative colitis and Crohn disease refractory to standard treatment.¹ Vedolizumab is thought to be gut specific, blocking integrins specific to T lymphocytes destined for the gastrointestinal tract and their interaction with endothelial cells, thereby modulating the adaptive immune system in the gut without systemic immunosuppression.² It generally is well tolerated, and acne rarely has been reported as an adverse event.^3,4 We present a case of acne fulminans without systemic symptoms (AF-WOSS) as a severe side effect of vedolizumab that responded very well to systemic steroids and oral isotretinoin in addition to the discontinuation of treatment.

A 46-year-old obese man presented to our dermatology clinic with a chief complaint of rapidly progressive tender skin lesions. The patient had a long-standing history of severe fistulating and stricturing Crohn disease status post–bowel resection with ileostomy and had recently started treatment with vedolizumab after failing treatment with infliximab, adalimumab, certolizumab pegol, ustekinumab, and methotrexate. Several weeks after beginning infusions of vedolizumab, the patient began to develop many erythematous papules and pustules on the face, chest (Figure 1), and buttocks that rapidly progressed into painful and coalescing nodules and cysts over the next several months. He was prescribed benzoyl peroxide wash 10% as well as several weeks of oral doxycycline 100 mg twice daily with no improvement. The patient denied any other new medications or triggers, fever, chills, bone pain, headache, fatigue, or myalgia. The skin involvement continued to worsen with successive vedolizumab infusions over a period of 8 weeks, which ultimately resulted in cessation of vedolizumab.

Physical examination revealed large, tender, pink, erythematous, and indurated plaques that were heavily studded with pink papules, pustules, and nodules on the cheeks (Figure 2), central chest, and buttocks. A punch biopsy of a pustule on the cheek showed ruptured suppurative folliculitis. The patient subsequently was diagnosed with AF-WOSS.

The patient then completed a 7-day course of sulfamethoxazole-trimethoprim followed by a 10-day course of amoxicillin-clavulanic acid, neither of which led to improvement of the lesions. He then was started on an oral prednisone taper (1 mg/kg starting dose) that ultimately totaled 14 weeks in length due to his frequent flares any time prednisone was decreased below 40 mg daily. After 3 weeks on the oral prednisone, the patient was started on 0.3 mg/kg of concomitant oral isotretinoin every other day, which slowly was increased as tolerated until he reached a goal dose of roughly 150 mg/kg, which resolved the acneform papules and pustules and allowed for successful tapering off the prednisone.

Many studies have been published regarding the safety and side-effect profile of vedolizumab, but most do not report acne as an adverse event.^3-5 A German cohort study by Baumgart et al³ reported acne as a side effect in 15 of 212 (7.1%) patients but did not classify the severity. Another case report noted nodulocystic acne in a patient receiving vedolizumab for treatment of inflammatory bowel disease; however, this patient responded well to the use of a tetracycline antibiotic and was able to continue therapy with vedolizumab.⁵ Our patient demonstrated a severe and uncommon case of acne classified as AF-WOSS following initiation of therapy with vedolizumab, which required treatment with systemic steroids plus oral isotretinoin and resulted in cessation of vedolizumab.

As new therapies emerge, it is important to document new or severe adverse effects so providers can choose an appropriate therapy and adequately counsel patients regarding the side effects. Although vedolizumab was thought to have gut-specific action, there is new evidence to suggest that the principal ligand of the α4β7 integrin, mucosal addressin cell adhesion molecule-1, is not only expressed on gut endothelial cells but also on fibroblasts and melanomas, which may provide insight into the observed extraintestinal side effects of vedolizumab.⁶

Don’t like needles? Have we got a vaccine for you

Here’s a quick question: How do you turn the most annoying thing ever into something positive?

No, we’re not talking about politicians this time. No, not Elon Musk, either. Infomercials? Guess again. Humidity? Nope, even more annoying than that.

Give up? The most annoying thing ever is mosquitoes. This time, however, NPR reports that mosquitoes have been used to deliver a vaccine for the very disease they’ve been transmitting to their human food sources all these years.

In a recent proof-of-concept trial, investigators used CRISPR technology to genetically modify malaria-causing Plasmodium falciparum sporozoites, which just happen to live in the salivary glands of Anopheles mosquitoes. And since the Plasmodium parasites are already in the mosquitoes, it made sense to use the buzzy little critters as the delivery device for the vaccine.

More sense than a syringe, you ask? Have you ever tried to poke a syringe into the salivary gland of a mosquito? No, we thought not. Well, we can tell you from experience that it’s really, really hard. Never mind how we know. We just do.

The 14 study volunteers – who were paid $4,100 for their participation – were first exposed to hundreds of mosquitoes carrying the altered Plasmodium parasites. Then, to test the vaccine, they were exposed to mosquitoes that had actual, malaria-carrying Plasmodium. Half of the subjects got malaria, so the vaccine was only 50% effective, meaning there’s still work to do.

Meanwhile, the scientists here at LOTMEco are all over this mosquito-delivery business, working on a vaccine to prevent Elon Musk. Plan B involves some sort of really big swatter.
 

Climate change: Sleeping your life away

It’s no secret that climate change is raising the temperature on everything. You may think you’re getting relief when the sun goes down, but in some places it’s still hot. A new survey conducted in central Japan shows how bad it can be and how higher nighttime temperatures can have a serious impact on people’s health.

Public Domain Vectors

That online survey, the Sleep Quality Index for Daily Sleep, enabled the investigators to correlate sleep quality with daily temperature for 1,284 adults in 2011 and 2012 who completed the survey over 10 days.

Not only was there a significant difference in sleep disturbance among younger men (higher) versus older men, but the prevalence of sleep disturbance went up when the daytime temperature was above 24.8° C. They also found that disability-adjusted life-years (DALYs), which measure time lost through premature death and time lived in certain conditions that put one’s health at risk, were 81.8 years for the city of Nagoya (population, 2.2 million) in 2012.

The damage to health from sleep disorders caused by daily temperatures higher than 25° C “is comparable to that of heatstroke and must be addressed,” lead author Tomohiko Ihara of the University of Tokyo said in a written statement.

The researchers hope that this information will help sway legislators to consider the impact of higher nighttime temperatures and that it can be used to provide guidance for better sleep. The solution for now? Sleep with the air conditioner on. Your energy bill might increase, but just think about those DALYs. If using the AC lowers DALYs and increases time lived, then we say it’s worth it.
 

Maybe it would have been a dragon WITH cancer

If you ask a random person on the street to tell you all they know about the country of Wales, they’ll probably mention two things: One, the contorted collection of jumbled-up letters that is the Welsh language (looking at you, Llanfairpwllgwyngyll­gogery­chwyrn­drobwll­llan­tysilio­gogo­goch) and, two, the association with dragons. The Welsh flag even has a dragon on it.

With that in mind, take a guess as to what sort of statue art dealer Simon Wingett wanted to build in the Welsh town of Wrexham. No, not a monument to the second-longest place name in the world. Try again. His dragon would not be some piddly little thing either; he wanted a virtual kaiju overlooking the town, with the whole statue to stand about 60 meters high. That’s taller than the original 1954 Godzilla.

Artistic masterpieces may sell for frankly insane prices, but art dealers themselves are not the wealthiest of individuals, so Mr. Wingett needed money to fund his dragon-based dream. Lucky for him, he also happened to be the manager of a cancer charity – initially set up by Mr. Wingett’s father, who had throat cancer – which nominally aimed to provide equipment and resources to cancer patients in the Wrexham area.

Yes, this is going precisely where you think it’s going. From 2011 to 2018, when the charity closed, Mr. Wingett used the charity’s donations to fund his dragon statue – which never actually got built, by the way – to the tune of over 400,000 pounds. Of course, Mr. Wingett came under scrutiny when people started to notice that his cancer charity hadn’t actually done anything charitable since 2011, and he was recently banned by the Welsh High Court from serving as trustee of any charity for 10 years. Oh no, tragedy and horror! Truly a punishment worse than death itself.

Okay fine, he also has to pay back 117,000 pounds to actual legitimate cancer charities. The astute mathematicians out there may notice that 117,000 is a lot less than 400,000. But it’s just as the old saying goes: One-quarter of crime doesn’t pay. You can keep three-quarters of it, though, that’s completely fine.

An x-ray revealed a metal density in the area of concern that was consistent with a bullet fragment or other metallic foreign body. Since there were no lucencies on x-ray or tracking from the area of concern to the metacarpal, the diagnosis was confirmed as an infected foreign body. The history was very concerning for osteomyelitis, given that the patient had sustained a GSW and had undergone surgical repair with hardware. (Shifting hardware can also lead to callus formation and skin breakdown.)

The patient was told that he’d retained a bullet fragment or foreign body that caused a chronic infection and the recurrent drainage. In addition, the hardware spanning the gap between the remnants of his proximal and distal metacarpal had broken as a result of fatigue. He was referred to a surgeon to remove the foreign body and treat the infection. The patient was advised that he might also need replacement hardware and a bone graft.

The last full week of September brought a 4th straight week of declines in the number of new COVID-19 cases reported among children, according to the American Academy of Pediatrics and the Children’s Hospital Association.

The new-case total of 39,200 for the week of Sept. 23-29 was down by almost 28% from the previous week, with the month of September bringing a decline of about 57% in reported cases for the 45 states and territories that are still releasing pediatric COVID data on their health department websites, the AAP and CHA said in their joint weekly report.

New cases dropped in all four regions after the Northeast and West had seen increases the previous week, and the distribution of cases for the latest week was fairly even, with the Midwest and Northeast right around 10,000, the South slightly over 10,000, and the West under 10,000 by about the same amount. At the state level, the largest increases – around 1.5% – over the last 2 weeks occurred in Kentucky and Nevada, the AAP/CHA data show.

The cumulative number of COVID-19 cases in children was almost 14.8 million as of Sept. 29, with children representing 18.4% of all cases since the pandemic began, the AAP and CHA said. The Centers for Disease Control and Prevention, which is able to use a uniform age range of 0-17 years, puts total cases at 15.2 million and the proportion of child cases at 17.4%. Total deaths in children from COVID as of Oct. 3 were 1,745, the CDC reported.

New vaccinations, in the meantime, are being added in numbers only slightly higher than new cases. Initial COVID vaccinations for the week of Sept. 22-28 were about 44,000 for children under 5 years of age (down from 51,000 the week before), 24,000 for children aged 5-11 years (down from 28,000), and 17,000 for those aged 12-17 (down from 18,000), the AAP said in its weekly vaccination report.

To look at it another way, the total proportion of children under 5 years of age who had received at least one dose of COVID vaccine as of Sept. 28 was 6.5%, compared with 6.4% on Sept. 21, while the corresponding rates for children aged 5-11 and 12-17 were unchanged at 38.5% and 70.9%. The 12- to 17-year-olds, in fact, have been stuck at 70.9% since Sept. 13, according to data from the CDC.

In a recent study published in Vaccine, investigators attributed the discrepancies between age groups at least partly to the acceptance of misinformation about vaccine safety in general and the COVID-19 vaccines in particular.

“All of the misconceptions we studied focused in one way or another on the safety of vaccination, and that explains why people’s misbeliefs about vaccinating kids are so highly related to their concerns about vaccines in general. Unfortunately, those concerns weigh even more heavily when adults consider vaccinating children,” lead author Dan Romer, PhD, of the University of Pennsylvania, Philadelphia, said in a written statement.

The last full week of September brought a 4th straight week of declines in the number of new COVID-19 cases reported among children, according to the American Academy of Pediatrics and the Children’s Hospital Association.

The new-case total of 39,200 for the week of Sept. 23-29 was down by almost 28% from the previous week, with the month of September bringing a decline of about 57% in reported cases for the 45 states and territories that are still releasing pediatric COVID data on their health department websites, the AAP and CHA said in their joint weekly report.

New cases dropped in all four regions after the Northeast and West had seen increases the previous week, and the distribution of cases for the latest week was fairly even, with the Midwest and Northeast right around 10,000, the South slightly over 10,000, and the West under 10,000 by about the same amount. At the state level, the largest increases – around 1.5% – over the last 2 weeks occurred in Kentucky and Nevada, the AAP/CHA data show.

PARIS – What do doctors know about their patients’ sexual health? Not a lot. What about oncologists who treat women with breast cancer? Not much more. Yet sexual dysfunction has a significant impact on the quality of life of patients during and after cancer.

To determine the extent of sexual dysfunction among women with breast cancer, Maria Alice Franzoi, MD, an oncologist at Gustave Roussy Hospital, Villejuif, France, analyzed data concerning sexuality from the CANTO cohort study. She showed that sexual dysfunction often predates the cancer diagnosis and doesn’t improve but rather worsens in the following 2 years. She presented her results at the annual meeting of the European Society for Medical Oncology.
 

Present at diagnosis

Dr. Franzoi, whose research projects have focused on patient monitoring post cancer, drew her conclusions from the data provided by CANTO, a longitudinal, prospective cohort study that monitors women being treated for localized breast cancer. Study participants answered the EORTC-QLQ-BR23 quality-of-life questionnaire at the time of diagnosis (T0), 1 year after diagnosis (T1), and 2 years after diagnosis (T2). Four factors were employed to better define women’s sex-related problems: poor body image, poor sexual functioning (activity and desire), lack of sexual pleasure, and a complete lack of sexual activity.

The analysis focused on the responses of 7,895 patients in the CANTO cohort study on sexual activity; 4,523 of those patients answered questions about sexual pleasure. Female respondents who reported engaging in no sexual activity did not have to answer the questions in this second section.

“Seventy-five percent of patients reported at least one of the four concerns during the study,” noted Dr. Franzoi during her presentation. This finding highlights the fact that “sexual problems are already present at the time of diagnosis in a considerable number of patients,” she said. More than a third of participants complained of at least one of the four items.
 

Developments after diagnosis

The proportion of women who reported no arousal or poor sexual function remained stable at around 30% over time, meaning that the sexual problems were reported in similar numbers at T0, T1, and T2. “However, after cancer, more patients are worried about a lack of sexual pleasure (38.7% at T1 and 38.1% at T2, vs. 29.1% at T0) or report having a negative body image (57.8% at T1 and 52.5% at T2, vs. 32.1% at T0),” said Dr. Franzoi.

She identified the following three variables as being associated with sexual dysfunction 2 years after diagnosis: the existence of this problem at the time of diagnosis, the use of adjuvant hormone therapy, and severe depression or a very high stress level after the first year of treatment.
 

Inadequate specific treatment

“Sexual dysfunction is a major unmet need with a significant impact on quality of life,” said Maryam Lustberg, MD, an oncologist at Yale School of Medicine, New Haven, Conn., who was invited to discuss the results at the conference.

Dr. Franzoi observed that most participants with sexual dysfunction that had continued 2 years after diagnosis had not been referred to a doctor for this problem. “In terms of sexual function, it’s better at T2 than at T1, but only 41% of these women have been seen by a gynecologist, and only 15% have received specific treatment,” she reported, emphasizing the need to assess and treat these issues “proactively” at the time of diagnosis and during and after treatment.

“Now we need to work out what the best treatment approach is,” commented Dr. Lustberg. She said that cancers other than breast and gynecologic cancers should also be taken into consideration. She cited the Sexual Health Assessment in Women With Lung Cancer study, which recently revealed that after being diagnosed with lung cancer, female patients experienced a drop in sexual desire (31% vs. 15% before diagnosis) and an increase in vaginal discomfort or dryness (43% vs. 13% before diagnosis). This study, presented in August to the 2022 International Association for the Study of Lung Cancer World Conference on Lung Cancer, also revealed that different parameters affect satisfaction in one’s sex life, including fatigue, sadness, relationship problems with a partner, and even breathing. Dr. Lustberg concluded from this study that a multidisciplinary approach is needed for cancer survivors.

Dr. Franzoi received research funding from Resilience Care. Dr. Lustberg has links with AstraZeneca, Pfizer, Novartis, Sanofi, and Lilly.

In my previous article in June, 2022, we plowed through the billing and coding updates regarding critical care services, and, I hope that it helped our readers get more acquainted with the nuances of billing and coding in the ICU. In this piece, I would like to briefly elucidate three other areas of practice, which will be relevant to all physicians across various specialties.

Telehealth services

The Centers for Medicare & Medicaid Services (CMS) graciously added telehealth services temporarily to its list of services due to the COVID-19 public health emergency (PHE). Initially, the plan was to remove these from the list of covered services by the latter end of the COVID-19 PHE, which, created some uncertainty, or by December 31, 2021. Fortunately, CMS finalized that they will extend it through the end of the calendar year (CY) 2023. So, now all the telehealth services will remain on the CMS list until December 31, 2023. The general principle behind this ruling is to allow for more time for CMS and stakeholders to gather data and to submit support for requesting these services to be permanently added to the Medicare telehealth services list.

Not only has CMS extended the deadline for telehealth services but also they have gone far and beyond to extend some of the codes for cardiac and intensive cardiac rehabilitation until December 31, 2023, as well.

There has been a lot of debate regarding the geographic restrictions when it comes to telehealth visits for diagnosis, evaluation, or treatment of a mental health disorder. As per the latest Consolidated Appropriations Act of 2021 (Section 123), the home of the patient is a permissible site. But, the caveat is that there must be an in-person service with the practitioner/physician within 6 months prior to the initial telehealth visit. Additionally, there has to be a set frequency for subsequent in-person visits. And, usually the subsequent visits will need to be provided at least every 12 months. These requirements are not set in stone and can be changed on a case-by-case basis provided there is appropriate documentation in the chart.

Lastly, it is important to understand and use the appropriate telecommunication systems for the telehealth visits and the modifiers that are associated with them. By definition, it has to be audio and video equipment that allows two-way, real-time interactive communication between the patient and the provider when used for telehealth services for the diagnosis, evaluation, or treatment of mental health disorders. But, CMS is in the process of amending it to include audio-only communications technology. At this time, the use of audio-only interactive telecommunications system is limited to practitioners who have the capability to provide two-way audio/video communications but, where the patient is not capable, or does not consent to, the use of two-way audio/video technology. Modifier FQ should be attached to all the mental health services that were furnished using audio-only communications. And, mental health services can include services for treatment of substance use disorders (SUD). Please do not confuse modifier FQ with modifier 93 as FQ is only for behavioral health services. And, remember that the totality of the communication of information exchanged between the provider and the patient during the course of the synchronous telemedicine service (rendered via telephone or other real-time interactive audio only telecommunication system) must be of an amount and nature that is sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction.

Teaching physician services

As a general rule, a teaching physician can bill for the resident services only if they are present for the critical (key) portion of the service. But, there is one exception called the “primary care exception” under which in certain teaching hospital primary care centers, the teaching physician can bill for certain services as furnished independently by the resident without the teaching physician being physically present, but with the teaching physician’s review.

The current model to bill for office/outpatient E/M visit level is either based on either total time spent (personally) or medical-decision-making (MDM). When time is used to select the visit level only the time spent by the teaching physician in qualifying activities can be included for the purposes of the visit level selection. And, this includes the time the teaching physician was present with the resident performing those qualifying activities. Also, under the primary care exception, time cannot be used to select the visit level. This is to guard against the possibility of inappropriate coding that reflects residents’ inefficiencies rather than a measure of the total medically necessary time required to furnish the E/M services.

ICD-10 updates

Usually, the ICD-10 codes are updated annually and take effect every October 1. Some of the most relevant updates are as follows:

1. U09.9 Post COVID-19 condition, unspecified: This should be used to document sequelae of COVID-19 or “long COVID” conditions, after the acute illness has resolved. But, remember to code the conditions related to COVID-19 first and do not use this code with an active or current COVID-19 infection.

2. U07.0 Vaping-related disorder: This should be used for all vaping-related illnesses. However, additional codes for other diagnoses such as acute respiratory failure, acute respiratory distress syndrome, or pneumonitis can also be used with this code. Other respiratory signs and symptoms such as cough and shortness of breath should not be coded separately.

3. Cough is one of the most common reasons for referral to a pulmonologist. The CDC has expanded these codes so please remember to code the most specific diagnosis as deemed appropriate.

R05.1 Acute cough

R05.2 Subacute cough

R05.3 Chronic cough

R05.4 Cough, syncope

R05.8 Other specified cough

R05.9 Cough, unspecified

We will be back with some more exciting and intriguing billing and coding updates in our next article and hope to see everyone at CHEST 2022 in Nashville., TN.

Not only has CMS extended the deadline for telehealth services but also they have gone far and beyond to extend some of the codes for cardiac and intensive cardiac rehabilitation until December 31, 2023, as well.

There has been a lot of debate regarding the geographic restrictions when it comes to telehealth visits for diagnosis, evaluation, or treatment of a mental health disorder. As per the latest Consolidated Appropriations Act of 2021 (Section 123), the home of the patient is a permissible site. But, the caveat is that there must be an in-person service with the practitioner/physician within 6 months prior to the initial telehealth visit. Additionally, there has to be a set frequency for subsequent in-person visits. And, usually the subsequent visits will need to be provided at least every 12 months. These requirements are not set in stone and can be changed on a case-by-case basis provided there is appropriate documentation in the chart.

Lastly, it is important to understand and use the appropriate telecommunication systems for the telehealth visits and the modifiers that are associated with them. By definition, it has to be audio and video equipment that allows two-way, real-time interactive communication between the patient and the provider when used for telehealth services for the diagnosis, evaluation, or treatment of mental health disorders. But, CMS is in the process of amending it to include audio-only communications technology. At this time, the use of audio-only interactive telecommunications system is limited to practitioners who have the capability to provide two-way audio/video communications but, where the patient is not capable, or does not consent to, the use of two-way audio/video technology. Modifier FQ should be attached to all the mental health services that were furnished using audio-only communications. And, mental health services can include services for treatment of substance use disorders (SUD). Please do not confuse modifier FQ with modifier 93 as FQ is only for behavioral health services. And, remember that the totality of the communication of information exchanged between the provider and the patient during the course of the synchronous telemedicine service (rendered via telephone or other real-time interactive audio only telecommunication system) must be of an amount and nature that is sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction.

Teaching physician services

As a general rule, a teaching physician can bill for the resident services only if they are present for the critical (key) portion of the service. But, there is one exception called the “primary care exception” under which in certain teaching hospital primary care centers, the teaching physician can bill for certain services as furnished independently by the resident without the teaching physician being physically present, but with the teaching physician’s review.

The current model to bill for office/outpatient E/M visit level is either based on either total time spent (personally) or medical-decision-making (MDM). When time is used to select the visit level only the time spent by the teaching physician in qualifying activities can be included for the purposes of the visit level selection. And, this includes the time the teaching physician was present with the resident performing those qualifying activities. Also, under the primary care exception, time cannot be used to select the visit level. This is to guard against the possibility of inappropriate coding that reflects residents’ inefficiencies rather than a measure of the total medically necessary time required to furnish the E/M services.

ICD-10 updates

Usually, the ICD-10 codes are updated annually and take effect every October 1. Some of the most relevant updates are as follows:

1. U09.9 Post COVID-19 condition, unspecified: This should be used to document sequelae of COVID-19 or “long COVID” conditions, after the acute illness has resolved. But, remember to code the conditions related to COVID-19 first and do not use this code with an active or current COVID-19 infection.

2. U07.0 Vaping-related disorder: This should be used for all vaping-related illnesses. However, additional codes for other diagnoses such as acute respiratory failure, acute respiratory distress syndrome, or pneumonitis can also be used with this code. Other respiratory signs and symptoms such as cough and shortness of breath should not be coded separately.

3. Cough is one of the most common reasons for referral to a pulmonologist. The CDC has expanded these codes so please remember to code the most specific diagnosis as deemed appropriate.

R05.1 Acute cough

R05.2 Subacute cough

R05.3 Chronic cough

R05.4 Cough, syncope

R05.8 Other specified cough

R05.9 Cough, unspecified
