Abstract
The goal of this study was to determine whether teledermatology referrals differ significantly from in-person referrals with respect to case complexity and diagnosis of cases referred. Teledermatology cases were compared to in-person cases seen by the same university dermatologist who also reviews the teledermatology cases. These were also compared with in-person cases evaluated by a different dermatologist at local clinics using traditional referral patterns. Study parameters included Current Procedural Terminology (CPT) codes as a measure of case complexity, International Classification of Disease (ICD) codes as a measure of case types, and time from referral to actual consultation. The most common CPT codes used for teledermatology were 99241 and 99242 with no significant differences in the frequency of assigned CPT codes for teledermatology versus in-person consultation. An analysis of the diagnostic codes revealed no significant differences between the types of cases referred to telemedicine and those referred for in-person consultation. Time between referral and actual encounter with the dermatologist was significantly shorter via telemedicine than either local or university clinic in-person visits.
