Compound prescription drug coverage; health insurance plan providing prescription drug coverage; effective date.

HB 3368 requires health insurance plans covering prescription drugs to allow pharmacies (including those providing compound drugs) to bid for pharmacy service contracts at least every three years. It applies specifically to plans not already using an open pharmacy network, meaning insurers must periodically seek bids from pharmacies rather than maintaining fixed contracts. The bill does not affect plans that already operate open networks, and it takes effect on November 1, 2026. This changes how insurers select pharmacy partners for covered drug services.
