A. Group health coverage, including any form of self-insurance, offered, issued or renewed under the Health Care Purchasing Act that offers a prescription drug benefit 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 patient;
(2) the patient 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 patient's prescription drug fills.
B. Group health coverage, including any form of self-insurance, offered, issued or renewed under the Health Care Purchasing Act that offers a prescription drug benefit 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 group health plan, the prescribing practitioner and a pharmacist. The group health plan 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 group health plan 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.
