Abstract
Main Outcome Measures: The average cost of Mohs and TSE per patient for the treatment and repair of NMSC; adequacy of TSE margins after the initial procedure (because this outcome affects overall cost). Results: Mohs was cost comparable to TSE when the subsequent procedure for inadequate TSE margins after permanent section was Mohs ($937 vs $1029; P=.16) or a subsequent TSE ($937 vs $944; P=.53). When facilitybased frozen sections were requested for TSE, Mohs was significantly less costly ($956 vs $1399; P .001). The cost difference between Mohs and TSE was sensitive to the type of repair chosen.
