HI SB2656

Requires health insurers, mutual benefit societies, and health maintenance organizations to permit medication synchronization by applying prorated daily cost-sharing rates for prescriptions dispensed for less than a 30-day supply when patients request or agree to partial supplies.

Prohibits insurers from denying coverage for maintenance medications dispensed as partial supplies for synchronization purposes and requires network pharmacies to override "refill too soon" denial codes.

Mandates that dispensing fees for partially filled prescriptions be paid in full for each prescription dispensed, regardless of any prorated copayment or synchronization service fees.

Allows network pharmacies to identify an anchor prescription to which other prescriptions may be synchronized, with medications in unbreakable packages (eye drops, inhalers, creams, ointments) automatically designated as anchor prescriptions.

Excludes Schedule II narcotic controlled substances from medication synchronization eligibility and amends the definition of pharmacy practice to include adjusting prescription supply for medication synchronization purposes; effective July 1, 2050 and repealed July 1, 2023.
