Mechanical Stretching Devices for Contracture and Joint Stiffness (CPB 0405, reviewed 2026-06-30)
Aetna covers dynamic splinting devices for the knee, elbow, wrist, finger or toe when there are documented signs and symptoms of significant motion stiffness or loss and the splint is used as an adjunct to occupational or physical therapy at least 3 weeks after injury or surgery, or when the member has a documented history of motion loss in a joint and is in the acute post-operative period after a second or subsequent surgery. The policy also covers the dynamic adjustable ankle extension/flexion device (e.g., JAS Ankle) for contractures, the EZ Turnbuckle orthosis after open reduction internal fixation for radial head fracture, and continued mechanical stretching when documented improvement in range of motion is shown. Dynamic splinting for carpal tunnel syndrome, cerebral palsy, foot drop associated with neuromuscular diseases, multiple sclerosis, stroke and plantar fasciitis, JAS splints, PASS devices such as the ERMI flexionators and extensionators, SaeboMas, Medi-Dyne Prostretch, and mechanical stretching for skin graft contracture are considered experimental, investigational or unproven.
Aetna · Identified Aug 16, 2026Medium impact
Seat Lifts and Patient Lifts (CPB 0459, reviewed 2026-07-16)
Aetna covers seat lift mechanisms as durable medical equipment only when the member cannot stand up from a regular armchair at home, has severe arthritis of the hip or knee or severe neuromuscular disease, the device is prescribed to effect improvement or arrest or slow deterioration, and the member can ambulate once standing. Stand-assist lifts, patient lifts, bariatric lifts, and multi-positional transfer systems are covered only when their own separate criteria are met, and spring-release seat lifts with a catapult-type motion are considered experimental, investigational, or unproven. the policy was last reviewed 07/16/2026.
Aetna · Identified Aug 13, 2026Medium impact
Palivizumab (Synagis) (CPB 0318, reviewed 2025-11-24)
Aetna considers palivizumab (Synagis) medically necessary for commercial medical plans for up to 5 doses per RSV season to prevent serious lower respiratory tract disease caused by RSV, when a member has a qualifying diagnosis such as prematurity, chronic lung disease of prematurity, hemodynamically significant congenital heart disease, cystic fibrosis or profound immunocompromise and the associated criteria are met. Palivizumab is excluded for members who have received nirsevimab-alip (Beyfortus) in the same RSV season. The American Academy of Pediatrics stated that in July 2025 it no longer routinely recommends using Synagis.
Aetna · Identified Aug 12, 2026Medium impact
Orthopedic Casts, Braces and Splints (CPB 0009, reviewed 2026-01-20)
Aetna considers orthoses, casts and splints medically necessary when they treat disease or injury for the listed indications, including lumbar and thoracic-lumbar-sacral braces that facilitate healing after a spine injury or spinal surgery, post-operative back braces applied within 6 weeks after spinal surgery, cervical braces for neck injury and torticollis, Unna boots for non-fracture care, air casts for fractures or other injuries, and prefabricated volar wrist braces for carpal tunnel syndrome. Prophylactic lumbar supports are considered experimental, investigational, or unproven, and elastic support garments and protective body socks do not meet Aetna's definition of covered durable medical equipment. Custom-fitted back braces are medically necessary where there is a failure, contraindication or intolerance to an unmodified, prefabricated back brace, and medical record documentation must support all coverage criteria because supplier-prepared statements and practitioner attestations alone are not sufficient.
