Summary
New policy effective January 1, 2026 establishes comprehensive medical necessity criteria for definitive lower limb prostheses, requiring preauthorization, in-person functional assessments with validated tools, and specific K-level determinations. The policy includes detailed coverage criteria for prosthetic components based on functional levels and restricts certain items like mechanical socket adjustment systems.
Action Required
Before January 1, 2026: Billing team must implement preauthorization requirements for all definitive prosthesis codes (L5010-L5341 and associated components). Providers must conduct in-person evaluations with validated functional assessment tools to determine K-levels before ordering. Update billing system to flag these codes for prior auth and create documentation templates including functional level assessments, residual limb maturity confirmation, and motivation to ambulate. Train staff on new criteria linking specific prosthetic components to functional levels (K0-K4). Claims without proper preauthorization and documentation will be denied.
