Summary
Aetna updated its upper limb prosthetics policy (CPB 0399, effective 2026-07-16) clarifying medical necessity criteria, device coverage, and payment rules. Key changes include expanded coverage for myoelectric prostheses under specific conditions, explicit limitations on test sockets (max 2), replacement liners (max 2 per 12 months), and prosthetic sheaths (max 12 in 12 months), plus designation of multiple devices as experimental/investigational. The policy explicitly excludes cosmetic upgrades, sporting prosthetics, and water prosthetics, and clarifies that evaluation, measurement, casting, fitting, CAD-CAM fabrication, batteries, and chargers are included in base prosthesis reimbursement with no separate payment.
Action Required
By 2026-07-16, billing team must: (1) Update billing system to enforce limits on test sockets (maximum 2 per prosthesis) and replacement liners (maximum 2 per 12 months); (2) Stop billing separately for evaluation, measurement, casting, fitting, adjustments, CAD-CAM fabrication, batteries (L7360, L7364, L7367, L8505), and battery chargers (L7362, L7366, L7368) when billed with powered prosthetic base items—these are now bundled into base prosthesis reimbursement; (3) Deny claims for codes L5681, L5683, L6696, L6697 without documented functional/physiological need (not just "atypical amputation" notation); (4) Implement edits to reject claims for experimental devices including Revo, Boa click systems, COAPT control, Pattern recognition, Targeted muscle re-innervation, Espire Pro Elbow, and Metacarpal GEM prosthetic hand; (5) Update prior authorization templates to require myoelectric prosthesis criteria documentation: adequate cognitive/neurologic ability, minimum microvolt threshold, failed standard body-powered attempt, and absence of interfering comorbidities; (6) Add system rules to deny duplication/upgrades of functional prostheses, cosmetic prosthetics, donning sleeves, sporting/leisure prosthetics, and water prosthetics; (7) Configure system to reject items still under manufacturer warranty as not medically necessary. Providers must document medical necessity; claims lacking proper authorization and documentation will be denied and may require appeal or resubmission.
