What should providers do when the administered drug dose does not match the total units in a single-dose container and no waste is documented?
Providers should implement a sound practice to code and bill the applicable units based on the entire package administered, and documentation should reflect the entire dosage was administered to the patient. It is not recommended to apply this modifier as an alternative to the JW modifier when it is not apparent in the infusion record or medication administration record (MAR) whether the entire amount of the single-dose or single-use drug was used. Meaning, if the documented total amount/dose administered does not equal the number of units for the entire container or package, and the clinician fails to document any discarded/wasted drug, it would not be appropriate to apply modifier JZ to the HCPCS code.
