Background: Use of Mohs micrographic surgery (MMS) is highly prevalent, but little data are available on how surgeon experience affects surgical practice patterns.
Objective: To determine differences in use of MMS among surgeons of varying experience.
Materials and methods: This cross-sectional study sampled from clinicians billing ≥200 mean annual Mohs surgery claims from the 2012 to 2018 Medicare Public Use File. The primary outcome was mean annual Mohs surgery claims for clinicians of varying experience. Secondary outcomes included use of flaps/grafts and prescribing of oral antibiotics, benzodiazepines, and opioids.
Results: Among 1,759 unique surgeons, those with 16 to 20 years of experience performed the most mean annual (95% confidence interval) Mohs surgical cases (578.7 [556.7-600.6]). Surgeons with 21 to 25 years of experience prescribed the most antibiotics (240.2 [216.5-263.8] mean annual claims), whereas those with >35 years of experience prescribed the longest courses (15.3 [14.2-16.4] days).
Conclusion: Midcareer surgeons performed the most mean annual Mohs surgery cases, whereas later career surgeons prescribed more frequent and longer courses of antibiotics suggesting changing practice patterns with additional years of experience.
