If you present a single prescription form to your pharmacist, you should receive your prescription in a single order and only be billed once. Your pharmacist should also receive only one dispensing fee each time a prescription is filled or refilled. The pharmacist should not intentionally split a single prescription into two or more separately billed orders. This should not be confused with tablet splitting, which permits a pharmacist to fill a prescription at a higher dosage so that the patient can split the medication (typically a scored tablet) in half. Some plans encourage tablet splitting, when appropriate, because the patient receives a double supply of the medication for a lower out-of-pocket cost. You should call your plan to see if tablet splitting is permitted.
