New Modifier Required on all Single-Use Drugs- JZ and JW Modifiers
Attention providers and suppliers, there is a new modifier in town! Starting July 1, 2023, Modifier JZ - Zero Drug wasted will be required on all claims to attest there is no drug leftover, If applicable. Meaning there is zero drug amount discarded, and there was no leftover drug administered to any patient. This article will cover when the new modifier is reported and when it is not reported, how to report it on a claim, and other important information you need to know.
There is another modifier we should be familiar with, the JW modifier; this modifier has been required on claims since January 01, 2017, if applicable. The JW modifier is required to be reported on claims if there was a drug amount that was discarded when using a single-dose container. In addition, using the JW modifier indicates the drug is eligible for payment under the discarded drug policy. Therefore, CMS provides payment for the administered dose and the discarded amount. Using the JW modifier qualifies for separate reimbursement to providers and suppliers.
It will be required to have one of the modifiers, JZ or JW, on a claim for a single dose, never both. Documentation requires the records to clearly document the portion of the drug administered, wasted, and leftover in the medical record.
Reasoning for the new JZ modifier
According to CMS, "Because of observed low compliance with JW modifier use (leading to incomplete JW modifier data) and because the discarded drug refund amounts rely on this data, we established that a separate modifier, the JZ modifier, will be required on claims for single-dose container drugs to attest when there are no discarded amounts no later than July 1, 2023. "
When is the JW and JZ modifier not used?
If the drug is not payable in the setting, then the modifiers are not required. For example, Rural Health Clinic (RHC) and
Federally Qualified Health Centers (FQHC) are paid under a different payment system using a packaged rate. If a drug is packaged, it is not separately reportable as it is included in the payment. If a drug is assigned the status indicator N1, it is a "Packaged service/item; no separate payment made."
Example: J1756- Injection, iron sucrose, 1 mg, has an ASC Payment indicator of N1- Packaged service/No separate payment made. and the APC Status indicator is N - Packaged into APC Rates.
The modifiers are not required when billing vaccines; these are excluded as vaccines are often billed by mass immunizers using roster billing, which is not set up to accommodate modifiers.
The JW modifier is only used for the amount identified on the package, never if there is an overfilled drug.
Less than the billing unit should not be reported using these modifiers; if there is anything less than a full unit, the provider reports the full unit was administered using the JZ Modifier. According to CMS, "The units billed must correspond with the smallest dose (vial) available for purchase from the manufacturer(s) that could provide the appropriate dose for the patient while minimizing any wastage." to "The units billed should where possible correspond with the smallest dose (vial) available for purchase from the manufacturer(s) that could provide the appropriate dose for the patient, while minimizing any wastage."
When are the Modifiers used?
The modifiers will apply to all separately payable drugs assigned a payment indicator of K2- Drugs and biologicals paid separately when provided integral to a surgical procedure on the ASC list; payment based on OPPS rate. With the exceptions listed above, all claims reporting single-dose container drugs, including Not Otherwise Classified (NOC) codes, must be reported and documented in the patient's records. If a drug has a status indicator of "G- pass through biologicals" or K- Non-passthrough drugs and non-implantable biologicals, including therapeutic radiopharmaceuticals."
How are these reported on a claim?
When reporting the drug used on a claim, you may need to report two line items. Report one line for the HCPCS Code, the amount administered, (if no waste report JZ on the same line), and if reporting a discarded amount report Modifier JW as an additional line item.
First line item:
One line will show the HCPCS or payment code with modifier JZ showing the number of units administered (if there is Zero waste), add a second line item if reporting any discarded amounts.
- using the JZ modifier attesting there were no discarded or leftover amounts, reporting the number of units given to the patient.
Second line item
On a second line report, the same HCPCS code or payment code using the appropriate modifier, if there are drugs left over.
- using the JW modifier and the number of units not used in the units field

Start reporting the new modifier now.
You can start using the new modifier anytime after the effective date of January 01, 2023, and I suggest starting now to avoid problems later, such as audits.
CMS is implementing the JZ modifier in phases:
Providers and suppliers may report the JZ modifier as early as January 1, 2023
The JZ modifier is required on applicable claims beginning July 1, 2023
After January 1, 2017, claims are subject to review if the JW modifier is used incorrectly.
After July 1, 2023, claims not reporting the JW or JZ modifier are subject to audits.
On or after October 1, 2023, claims may be returned as unable to process.
When JW and JZ are not used
Status indicator N1
Less than a full unit
When to report JW and JZ modifiers
Payment indicator of K2
Not Otherwise Classified (NOC) codes
Status indicator of "G" passthrough drugs
Status indicator of "K" non-passthrough drugs
Reporting on a claim
If there is zero waste, you will report the HCPCS code and the total amount administered on one line with the JZ Modifier. If you are reporting any leftover drug, you need to report two line items; one for the drug code with the number of units used and one with the drug code, the JW modifier, and applicable units for discarded amounts.
