Pulsed Radiofrequency (CPB 0735, reviewed 2026-10-21)
Aetna's Clinical Policy Bulletin 0735 considers pulsed radiofrequency experimental, investigational, or unproven for all indications in its list, because its effectiveness has not been established. The list includes indications such as carpal tunnel syndrome, chronic knee pain, low back pain, trigeminal neuralgia, and headache. The policy also considers the Stimpod NMS460 nerve stimulator for post-amputation pain, combined ganglion impar block and pulsed radiofrequency for pudendal neuralgia, and combined platelet-rich plasma to the Gasserian ganglion and pulsed radiofrequency for trigeminal neuralgia experimental, investigational, or unproven.

Diabetic Neuropathy: Selected Treatments (CPB 0729, reviewed 2026-10-21)
Aetna's Clinical Policy Bulletin 0729 sets the medical necessity rules for selected treatments of diabetic neuropathy. Percutaneous electrical stimulation is considered medically necessary for members who failed to adequately respond to conventional treatments, but use for more than 4 weeks is considered not medically necessary, and dorsal column stimulation is medically necessary for members who meet the criteria in CPB 0194 - Spinal Cord Stimulation. The bulletin lists many other interventions, including acupuncture, dorsal root ganglion stimulation, peripheral nerve blocks and tumor necrosis factor-alpha inhibitors, as experimental, investigational, or unproven for this indication.

Diabetic Neuropathy: Selected Treatments (CPB 0729, reviewed 2026-02-24)
Aetna considers percutaneous electrical stimulation medically necessary for diabetic neuropathy only for members who did not respond adequately to conventional treatments, including anti-convulsants (especially pregabalin), anti-depressants (such as amitriptyline and duloxetine), and other agents such as capsaicin and isosorbide dinitrate spray. Use of percutaneous electrical stimulation for more than 4 weeks for diabetic neuropathy is considered not medically necessary. Dorsal column stimulation is considered medically necessary for members with diabetic peripheral neuropathy who meet the criteria in CPB 0194 (Spinal Cord Stimulation), while acupuncture, dorsal root ganglion stimulation, ozone therapy, peripheral nerve blocks and low-level laser therapy are considered experimental, investigational, or unproven for diabetic neuropathy because their clinical value for this indication has not been established.
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.
