Summary

Aetna updated its Medical Clinical Policy Bulletin 0405 on mechanical stretching devices for contracture and joint stiffness, effective immediately. The policy defines medical necessity criteria for dynamic splinting devices as DME and explicitly lists which devices and indications are NOT covered (experimental/investigational). Key requirement: All claims must include a Standard Written Order (SWO) from a treating practitioner (MD/DO/PA/NP/CNS) with complete documentation in the medical record; supplier statements alone are insufficient.

Action Required

Action needed
IMMEDIATE (effective 2026-06-30): Billing team must implement the following: (1) Update billing system to REQUIRE a Standard Written Order (SWO) from a treating practitioner (MD, DO, PA, NP, or CNS only—NOT therapists/orthotists) before ANY claim is submitted for mechanical stretching devices (CPT 29126, 29131, 29505, 29515, 29105 and HCPCS E1800-E1831). Reject/block claims without completed SWO. (2) Verify SWO includes: member name/ID, order date, item description (HCPCS code, narrative, or brand/model), all separately billed accessories/options, HCPCS code and quantity per item, practitioner name/NPI, and practitioner signature. (3) Flag and DENY all claims for non-covered devices: JAS Elbow/Shoulder/Knee/Wrist, ERMI Knee/Ankle Flexionator, SaeboMas, Kinova mechanical arm support, Medi-Dyne Prostretch, JAS EZ, Elite Seat knee extension, EZ Turnbuckle orthosis for radial head ORIF, and any dynamic splinting for: carpal tunnel syndrome, cerebral palsy, foot drop, hallux valgus, head/spinal cord injury, botox outcomes, ankle/shoulder injuries, MS, muscular dystrophy, plantar fasciitis, rheumatoid arthritis, stroke, or trismus. (4) Require documented medical record evidence (NOT supplier statements or attestations alone) proving: (a) for sub-acute/post-op use: signs/symptoms of significant motion stiffness at least 3 weeks post-injury/surgery WITH concurrent OT/PT, OR (b) for repeat surgery: prior documented stiffness history, prior surgery to improve motion, NOW in acute post-op period after second/subsequent surgery. (5) For ongoing device use, require documented ROM improvement. Denials will result without compliant documentation and SWO. Coordinate with providers to educate on SWO completion and documentation requirements.
