Billing for Drug Wastage: JW and JZ Modifier
Properly billing for drug wastage and associated modifiers helps to prevent claims processing errors and denials while ensuring you receive correct reimbursement.
Providers and suppliers are to care for and administer drugs and biologicals to patients in such a way that they can be used most efficiently and in a clinically appropriate manner.
When a billing provider or supplier must discard the remainder of a single-dose container or single-use package after administering a dose to a patient, Medicare provides payment for the amount of drug or biological discarded as well as the dose administered, up to the amount of the drug or biological as indicated on the vial or package label.
HCPCS Code Billing Unit
You must ensure that units of drugs or biologicals administered to Medicare patients are accurately reported according to the complete HCPCS code descriptor. Prior to submitting Medicare claims for drugs or biologicals, it is important to review the complete long descriptor for all applicable HCPCS codes.
Example: When the HCPCS code long descriptor for a specific drug specifies “per 100 mg” and the quantity administered is 200 mg, then the number of billable units for that HCPCS code is equal to two units.
Caution: Do not bill the units for drugs based on the way the drug is packaged, priced, stored or stocked.
Modifiers JW and JZ
Modifiers JW and JZ are required to be billed when applicable. These modifier requirements apply to separately payable drugs under Part B that are supplied in a single-dose container or single-use package based on FDA-approved labeling.
- JW Modifier (Effective 1/1/2017): “Drug amount discarded/not administered to any patient”.
The JW modifier must be reported on a claim to identify the amount of drug discarded and eligible for payment under the discarded drug policy.
Note: The JW modifier must be reported for the discarded amount from a single-dose container or package.
JW Modifier Billing Example
The HCPCS code long descriptor for a specific drug specifies “per one mg.” However, the single dosage vial for that specific drug HCPCS code contains 50 mg. The prescribed dosage for a patient is 80 mg.; therefore, two vials are prepared. A total of 80 mg is administered to the patient.
Report two claim lines applicable to that drug HCPCS code on the claim:- One line is billed with 80 units
- The second line is billed with 20 units and modifier JW (wastage)
- JZ Modifier (Implemented 7/1/2023): “Zero drug amount discarded/not administered to any patient”
The JZ modifier is required to be reported on a claim that includes drugs from single-dose container or package that are separately payable under Medicare Part B when there are no discarded amounts.
Note: The JZ modifier must be reported when there is no discarded amount of any drug from a single-dose container or package for which the JW modifier would be required if there were discarded amounts.
JZ Modifier Billing Example
The HCPCS code long descriptor for a specific drug specifies “per one (1) mg.” However, the single dosage vial for that specific drug HCPCS code contains 50 mg. The prescribed dosage for a patient is 100 mg.; therefore, two vials are prepared. A total of 100 mg is administered to the patient.
Report one claim line applicable to that drug HCPCS code on the claim:- One line is billed with 100 units and the modifier JZ (denoting no wastage)
JW Modifier Exception
The JW modifier is only applied to the amount of drug or biological that is discarded. An exception applies when the actual dose of the drug or biological administered is less than the billing unit. In these situations, the JW modifier is not billed for the wastage.
- Example: One billing unit of drug JXXXX is equal to ten mg (according to the HCPCS code long description) provided in a single use vial. The dosage ordered and administered to a Medicare patient was seven mg.
Although three mg of the drug JXXXX was not administered and was discarded, do not report the JW modifier on the claim because the smallest billable unit is already being billed. Reporting the JW modifier in this situation is a billing error that may result in overpayment.
In this scenario, report the JZ modifier n the claim to confirm there is no wastage.
JW and JZ modifiers do not apply when the drug is:
- Not separately payable (i.e., packaged OPPS or ASC drugs)
- Administered in the FQHC or RHC setting
- Overfilled amounts
