There is limited data available to correlate Mohs surgeons' behavior and years of experience. Moreover, the recent standardization of Mohs surgery training programs may allow for the prediction of future trends in Mohs micrographic surgery surgery based on the current behavior of recently trained Mohs surgeons.


To better understand the relationship between surgeon-specific characteristics and the number of Mohs micrographic surgery total cases, stages per case, number of grafts, and number of flaps performed by each surgeon.


Procedure data of 59 early-career, mid-career, and advanced-career Mohs surgeons were obtained from the website of the Centers for Medicare & Medicaid services.


No statistically significant differences were identified in the number of stages per case between the 3 groups. Two-proportion testing between advanced-career surgeons and early-career surgeons indicated a statistically significant difference in the number of surgeons performing flaps or grafts (p < .05). Similarly, a statistically significant difference was noticed between mid-career surgeons and early-career surgeons (p < .05).


The result of this study showed that more years of experience was significantly associated with reported utilization of flaps or grafts in practice. Furthermore, no significant difference was observed between years in practice and number of stages per case.
