Billing Code Overview
HCPCS Level II code L7520 represents repair of a prosthetic device, labor component, billed per 15 minutes. The service involves hands-on labor for assessment, adjustment, or repair work on a prosthetic device and is typically provided in outpatient settings such as prosthetics/orthotics clinics, durable medical equipment provider locations, or ambulatory surgical centers when repairs are performed on-site.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a transtibial amputation presents to a prosthetics clinic with a fractured pylon and loose cosmetic cover on their prosthetic leg after a fall at home. The prosthetist evaluates the device, documents component damage, and determines that on-site component repair is feasible. The clinic schedules a focused repair appointment. During the visit, the prosthetist performs diagnostics, removes the damaged component, fabricates or adjusts replacement parts, reassembles the prosthesis, and performs static and dynamic alignment checks and a brief gait assessment. Time spent on hands-on technical work and professional labor is tracked in 15-minute increments and billed using L7520 for the labor component of prosthetic device repair. The typical site of service is an outpatient prosthetics/orthotics clinic; repairs may also occur in outpatient rehabilitation clinics or skilled nursing facilities when allowed. The patient encounter includes device inspection, labor to repair or adjust the prosthesis, limited testing and functional assessment, and documentation of parts used and time spent. Payer adjudication may require documentation of medical necessity for repair versus replacement and clear time tracking when billing per 15 minutes with L7520.
