Intra-oral Appliances for Headaches and Trigeminal Neuralgia (CPB 0688, reviewed 2026-10-14)
Aetna considers intra-oral appliances, such as the Nociceptive Trigeminal Inhibition-Tension Suppression System, experimental, investigational, or unproven for treating headaches and trigeminal neuralgia, because the effectiveness of this approach for these indications has not been established. CPT 21110 and HCPCS codes for occlusal guards, removable appliance therapy, custom sleep apnea appliances, and oral appliance therapy are listed as not covered for the indications in this policy. Diagnosis codes for migraine, other headache syndromes, trigeminal neuralgia, and headache are also listed as not covered for the indications in this policy.

Headaches: Nonsurgical Management (CPB 0462, reviewed 2026-07-23)
Aetna covers intravenous dihydroergotamine (DHE) for status migrainosus, for other intractable severe migraine attacks unresponsive to analgesics and triptans, and for cluster headache attacks that do not respond to oxygen or triptans, when given in the emergency room, hospital or urgent care setting, and covers it for medication overuse headache in the inpatient setting. Aetna also covers intramuscular ketorolac for short-term management of acute migraine (5 days or less), intramuscular and intravenous steroids and intravenous magnesium for acute migraines, caffeine citrate infusion for post lumbar puncture headache when the member is unable to take caffeine orally, and eptinezumab-jjmr (Vyepti) for preventive migraine treatment in an adult when the criteria are met. Aetna considers cranio-sacral therapy, intra-oral splints for tension-type headaches, IV DHE for other headache types, and a list of other nonsurgical migraine and cluster headache interventions experimental, investigational or unproven.

Epidural Injection Technologies (CPB 0934, reviewed 2025-04-08)
As last reviewed on April 8, 2025, Aetna considers epidural blood patching medically necessary for post-dural puncture headache lasting longer than 24 hours, and for spontaneous intracranial hypotension with orthostatic headache lasting more than 2 weeks when brain MRI shows dural enhancement or spinal imaging shows epidural CSF collection or a CSF leak site. Repeat patching is covered when the first patch does not give prolonged relief and additional spinal imaging identifies a CSF leak site, and transforaminal patching is covered for post-dural puncture headache when the interlaminar approach was ineffective. Prophylactic patching, patching for post-dural puncture tinnitus, epidural fibrin glue or platelet-rich plasma patching for post-dural puncture headache, and real-time pressure-sensing epidural guidance are experimental, investigational or unproven.
