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.

Aetna's Clinical Policy Bulletin 0688 (reviewed 2025-12-29, historical material first detected 2026-08-18) states that intra-oral appliances such as the NTI-tss are considered experimental, investigational, or unproven for headaches and trigeminal neuralgia, and lists dental and sleep-appliance codes plus ICD-10 headache and trigeminal neuralgia codes as not covered for these indications. Practices should treat these services as non-covered for the stated diagnoses, confirm current applicability on Aetna's site, and not bill them to Aetna for those indications without verifying the plan's current position.
