An estimated 114,465 patients in Alabama are not receiving guideline-appropriate preventive migraine care from their primary care provider
How Alabama compares
Alabama's gap rate of 85.1% is consistent with the national pattern of 90.4%. Of the 430 primary care physicians in Alabama actively treating Medicare patients with migraine, 366 have never written a CGRP prescription. This is not a Alabama-specific failure — it is a national crisis that Alabama is experiencing alongside 47 other states.
What this means for patients
A patient with frequent migraine who sees their primary care physician in Alabama has a 85.1% chance that their doctor has never prescribed a CGRP-targeting therapy. This is not a reflection of physician knowledge or intent — it is the predictable consequence of prior authorization requirements that make CGRP prescribing administratively prohibitive in primary care.
About the data
Based on CMS Medicare Part D prescribing data — the only publicly available provider-level prescribing dataset in the United States. Active prescriber = 20+ triptan claims in the observation period. Medicare patients represent a subset of the total migraine population; the true gap is likely larger. Full methodology →
