Prescriptions covered under BCN’s drug riders are generally limited to a 30-day supply for one copayment when dispensed by a retail pharmacy. Members can obtain a 90-day supply of most medications for two copayments from their retail pharmacy. A 30-day first fill is required prior to a 90-day supply of brand-name medications. All specialty medications are limited to a 30-day fill. Mail order is also available. BCN has established quantity limits for certain medications based either on package size or to promote appropriate prescribing of drugs intended for once daily dosing.
