For Blue Cross Blue Shield of Rhode Island, surgical deactivation of migraine headache trigger sites is not covered for Medicare Advantage members and is considered not medically necessary for Commercial products because the available evidence is insufficient to determine effects on health outcomes.
Services determined to be not medically necessary or otherwise non‑covered are excluded from coverage. Providers and members should verify benefits using the member's subscriber agreement or employer agreement; those documents supersede this policy. If a provider renders a service that is determined to be not medically necessary (or is a non‑covered benefit), the provider may not charge the member unless the member was informed in advance and has agreed in writing to accept financial responsibility.
For Commercial products, surgical deactivation of migraine trigger sites is considered not medically necessary. The policy conclusion is based on an assessment that the evidence is insufficient to determine whether surgical deactivation improves health outcomes compared with established medical and behavioral therapies.
A denial or determination of noncoverage may result when services are judged not medically necessary or fall outside covered benefits. Providers should confirm member eligibility and benefits prior to performing procedures and follow the requirements in the member’s coverage documents; failure to obtain a member’s informed written agreement when required may preclude billing the member for non‑covered services.

Provider Requirements, Billing, and Verification
Prior authorization not applicable
This medical policy does not require prior authorization; prior authorization is not applicable for surgical deactivation of migraine headache trigger sites under this policy.
Verify member-specific prior authorization and benefits
Check the member's benefits and eligibility prior to providing services; this policy does not list product-specific prior authorization rules so contact the provider call center or review the member's Evidence of Coverage/Subscriber Agreement for member-specific requirements.
- For member-specific benefits, call the provider call center as benefits and eligibility are determined by the member's subscriber agreement or employer agreement.
- Member documents (Evidence of Coverage, Subscriber Agreement, Benefit booklet) supersede this medical policy.
Therapy context — document medical management alternatives
Document prior use of established medical management alternatives before considering surgical approaches; benefits may vary and approved non‑surgical therapies include acute and prophylactic pharmacologic treatments, onabotulinumtoxin A, CGRP agents, and behavioral therapies.
- Medical alternatives cited: triptans, ergotamines, certain CGRP receptor antagonists, non-opioid analgesics, antiemetics, prophylactic agents (antidepressants, beta-blockers, anti-seizure medications), onabotulinumtoxin A, and behavioral treatments.
Provider note — policy stance and member verification required
Note: surgical deactivation of migraine trigger sites is not covered for Medicare Advantage and is considered not medically necessary for Commercial products; ensure documentation reflects the policy stance and that member benefit verification occurs before scheduling.
- Medicare Advantage: surgical deactivation is not covered.
- Commercial Products: surgical deactivation is considered not medically necessary.
- Confirm member agreement if services are not covered or are non-covered benefits before proceeding.
Coding and submission — use unlisted procedure code(s)
Report the procedure with an appropriate unlisted CPT or HCPCS procedure code because no specific code exists; follow the payer's Unlisted Procedures policy for submission guidance.
- Use unlisted procedure code(s) for surgical deactivation of migraine trigger sites.
- Refer to the payer's 'Unlisted Procedures' related policy for correct submission instructions.
Verify member benefits and eligibility
Before providing services, contact the provider call center to verify the member's benefits, eligibility, and whether the subscriber agreement or employer agreement covers the service; those documents supersede this medical policy.
- Verify Evidence of Coverage, Subscriber Agreement, or Benefit booklet for contractual coverage details.
- Confirm whether the member must provide written agreement to pay if the service is non-covered or not medically necessary.
Coverage denial triggers — avoid listed CPT codes with migraine diagnosis
If any of the listed CPT codes are submitted with a diagnosis of migraine, the service will be considered not covered for Medicare Advantage and not medically necessary for Commercial products; avoid using these specific CPT codes with migraine diagnoses for surgical deactivation.
- 30140 — Submucous resection inferior turbinate, partial or complete, any method
- 30520 — Septoplasty or submucous resection, with or without cartilage scoring, contouring or replacement with graft
- 64716 — Neuroplasty and/or transposition; cranial nerve (specify)
- 67900 — Repair of brow ptosis (supraciliary, mid-forehead or coronal approach)
Denial risk — do not bill member for denied services without written agreement
Services determined to be not medically necessary or non-covered benefits may be denied and, unless the member provided written advance agreement to pay, the provider may not bill the member for those services.
- Do not charge the member for services denied as not medically necessary unless the member agreed in writing in advance to pay.
Background
Surgical deactivation targets presumed peripheral migraine trigger sites by identifying a patient’s predominant trigger location and removing, decompressing, or transecting branches of the trigeminal or occipital nerves and related tissues (muscle, fascia, or vessels). These procedures were developed after observations of migraine improvement following cosmetic forehead procedures and are described for four anatomic sites (frontal, temporal, rhinogenic, occipital). The proposed mechanism is interruption of peripheral nerve irritation thought to initiate migraine attacks, but evidence about long‑term clinical benefit and the contribution of placebo effects is limited.
