Intradiscal Procedures (CPB 0602, reviewed 2025-09-10)
Aetna considers thermal intradiscal procedures (TIPs) experimental, investigational, or unproven for relief of discogenic pain or other indications because their effectiveness has not been established. Intradiscal electrothermal therapy (IDET) is considered experimental and investigational and is not covered because of the lack of prospective randomized controlled clinical trials with adequate follow up demonstrating its effectiveness. The policy also lists other intradiscal procedures Aetna considers experimental, investigational, or unproven, including intradiscal glucocorticoid injection for low back pain, intradiscal injection of platelet-rich plasma for discogenic low back pain, and intradiscal injection of condoliase for lumbar disc herniation. The CPT codes 22526, 22527 and 62287 are listed as not covered for the indications in the policy, as are the HCPCS codes G0460, P9020, S2142, S2150 and S2348.

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.
