A new study led by the Headache & Migraine Policy Forum and recently published in the journal Headache quantifies the extent to which insurance barriers continue to limit access to effective migraine treatments. The study found that widespread “Payer Blocking,” whereby health plans delay and deny coverage for prescribed migraine therapies, severely disrupts care as the resulting misalignment between clinical guidelines and payer practices not only undermine patient outcomes but also increases costs across the health system.
