Are the HCPCS code units different from the NDC units?
Yes. Use the HCPCS code and service units as you have in the past; this is the basis for your reimbursement. NDC units are based upon the numeric quantity administered to the patient and the unit of measurement. The unit of measurement (UOM) codes are: F2 = International Unit GR=Gram ML = Milliliter UN = Unit (each) The actual metric decimal quantity administered and the unit of measurement are required for billing. If reporting a fraction, use a decimal point. For example: If three 0.5-ml vials are dispensed, the correct quantity to bill is 1.5 ml.
