Units Billed Drugs and Biologicals should be billed in multiples of the dosage specified in the HCPCS code long descriptor. The number of units billed should be assigned based on the dosage increment specified in that HCPCS long descriptor, and correspond to the actual amount of the drug administered to the patient, including any appropriate, discarded drug waste. If the drug dose used in the care of a patient is not a multiple of the HCPCS code dosage descriptor, the provider rounds to the next highest unit. Claims billed with excessive or insufficient units will be reviewed by a nurse, registered pharmacist, certified pharmacy technician, or certified coder to determine the actual amount administered and the correct number of billable/payable units.
