To our knowledge, visits in the ambulatory setting due to cutaneous fungal infections have not been recently characterized. To provide descriptive epidemiology on ambulatory cutaneous fungal infection visits, we analyzed office-based physician visits for cutaneous fungal infections recorded in the National Ambulatory Medical Care Survey (NAMCS) from 1990 to 1994. The International Classification of Diseases (ICD-9) was used to define the cutaneous fungal infections. Sampling weights were applied to achieve the nationally representative estimates. From 1990 to 1994, an estimated 21.6 million physician office visits at an estimated cost of $216 million/y (office visit plus medication costs) were made for cutaneous fungal infection diagnoses. The total cost of office visits (without medication costs) was approximately $116 million/y. The total cost of the top 5 medications was approximately $68 million/y. According to an analysis of visits per physician specialist, dermatologists had the largest proportion of visits for cutaneous fungal infections. The cost associated with the diagnosis and management of cutaneous fungal infections is significant. Of all the physician specialists, dermatologists treated the most cutaneous fungal infections.
