Prior authorization mental health carve out expansion

SF 2392 expands an existing carve-out from prior authorization requirements for specific mental health medications under Minnesota's Medicaid program. The bill directly affects Medicaid patients prescribed certain mental health drugs (like antipsychotics, antidepressants, or antianxiety medications) by preventing prior authorization barriers when: no generic equivalent exists; the drug was prescribed before July 1, 2003; or it's part of the patient's current treatment. Key provisions include automatically granting 60 days of prior authorization for brand-name mental health drugs when a generic becomes available, provided the brand was already in the patient's treatment. This reduces administrative hurdles for patients and providers while maintaining existing prior authorization rules for other medications.
