Accurate Reporting of Drug Units for HCPCS Billing
Ensure that units of drugs or biologicals administered to patients are accurately reported in dosage/units specified in the Healthcare Common Procedure Coding System (HCPCS) code descriptor. Before submitting, review the complete long descriptors for the appropriate HCPCS code. The short descriptors are limited to 28 characters so they do not always capture the complete description of the drug.
When submitting a claim, units should be reported in multiples of the dosage included in the long HCPCS descriptor. If the dosage given is not a multiple of the number provided in the HCPCS code description, the provider shall round up to the nearest whole number in order to express the number as a multiple.
When billing for a single-use vial and part of the drug is being discarded, bill the discarded amount with the JW modifier on a separate line. Multi-use vials are not subject to payment for any discarded amounts of the drug. Incorrect billing may result in the denial of the claim.
