HCPCS L-codes — Orthotics & prosthetics
L-codes span orthotics and prosthetics — spinal and knee orthoses, ankle-foot orthoses, and lower-limb prosthetic components. Several off-the-shelf and custom-fabricated orthoses now require Medicare prior authorization.
933 active codes in the April 2026 HCPCS file. PA = on Medicare's required prior-authorization list · Fee schedule = April 2026 DMEPOS amounts published.
