Health plans are prohibited from removing a drug from their formulary or moving it to a higher-cost benefit category for enrollees who were prescribed that drug during the plan year

Exceptions allow formulary changes when the FDA deems a drug unsafe, when a drug is withdrawn by the FDA or manufacturer, or when independent research issues warnings about imminent patient harm

Brand name drugs may be removed or moved to higher-cost tiers if a therapeutically equivalent generic, multisource brand, or interchangeable biologic is added at lower cost to the enrollee, with at least 60 days notice to prescribers, pharmacists, and affected enrollees

Effective January 1, 2026, applying to health plans offered, sold, issued, or renewed on or after that date
