A. An individual or group health maintenance organization contract that is delivered, issued for delivery or renewed in this state and that provides prescription drug benefits shall allow an enrollee to fill or refill a prescription for less than a thirty-day supply of the prescription drug, and apply a prorated daily copayment or coinsurance for the fill or refill, if:

(1)     the prescribing practitioner or the pharmacist determines the fill or refill to be in the best interest of the enrollee;

(2)     the enrollee requests or agrees to receive less than a thirty-day supply of the prescription drug; and

(3)     the reduced fill or refill is made for the purpose of synchronizing the enrollee’s prescription drug fills.

B. An individual or group health maintenance organization contract that is delivered, issued for delivery or renewed in this state and that provides prescription drug benefits shall not:

(1)     deny coverage for the filling of a chronic medication when the fill is made in accordance with a plan to synchronize multiple prescriptions for the enrollee pursuant to Subsection A of this section established among the health maintenance organization, the prescribing practitioner and a pharmacist. The health maintenance organization shall allow a pharmacy to override any denial indicating that a prescription is being refilled too soon for the purposes of medication synchronization; and

(2)     prorate a dispensing fee to a pharmacy that fills a prescription with less than a thirty-day supply of prescription drug pursuant to Subsection A of this section. The health maintenance organization shall pay in full a dispensing fee for a partially filled or refilled prescription for each prescription dispensed, regardless of any prorated copayment or coinsurance that the enrollee may pay for prescription synchronization services.
