The Surgical Management of Migraines and Chronic Headaches: A Cross-sectional Review of American Insurance Coverage.

BACKGROUND: Migraine headache can be an extremely debilitating condition, with pharmacotherapy for prophylaxis or treatment of acute symptoms being unsuccessful in a large proportion of patients. Surgical management of migraine has recently gained popularity as an alternative to pharmacotherapy for severe disease. However, the novel nature of these procedures may lead to variable insurance coverage, limiting access to care.

METHODS: A cross-sectional analysis of 101 US insurance companies was conducted. Companies were chosen based on greatest market share and enrollment per state. A Web-based search or phone call identified whether each company had a publicly available policy on nonsurgical or surgical management of migraine or headache. For companies with an available policy, coverage was categorized into covered, covered on a case-by-case basis, or never covered, with criteria required for coverage collected and categorized.

RESULTS: Of the 101 evaluated insurers, significantly fewer companies had a policy on surgical treatment for migraine or headache (n = 52 [52%]) compared with nonsurgical treatment (n = 78 [78%]) (P < 0.001). For companies with a policy, the most frequently covered nonsurgical treatments were biofeedback (n = 23 [92%]) and botulism toxin injections (n = 61 [88%]). Headaches were an approved indication for occipital nerve stimulation in 4% (n = 2) of company policies and nerve decompression in 2% (n = 1) of policies. Migraines were never offered preauthorized coverage for surgical procedures.

CONCLUSION: Approximately half of US insurance companies have a publicly available policy on surgical management of migraine or headache. Surgical treatment was seldom covered for the indication of headache and would never receive preauthorized coverage for migraine. Lack of coverage may create challenges in accessing surgical treatment. Additional prospective, controlled studies are necessary to further support the efficacy of surgical treatment.
