Health insurance; health insurance plan providing prescription drug coverage; insurance notification; effective date.

HB 1479 requires health insurance plans covering prescription drugs in Oklahoma to allow pharmacies to bid for contracts to provide pharmacy services at least every three years. It also mandates that insurers notify customers in writing at least 30 days before premium renewal if a medication they previously used will no longer be covered. The bill exempts insurers with open pharmacy networks from these requirements. The law takes effect November 1, 2025, affecting insurers, pharmacies, and policyholders.
