Aetna · Identified Aug 15, 2026Medium impact
Computerized Motion Diagnostic Imaging (CPB 0432, reviewed 2026-07-09)
Aetna considers computerized motion diagnostic imaging experimental, investigational, or unproven for evaluation of the spine or any other indication. Vertebral motion analysis and the DARI scan (functional motion analysis) are also considered experimental, investigational, or unproven because their effectiveness has not been established. The policy notes there is a lack of evidence in the peer-reviewed literature that these devices improve clinical outcomes.
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.
