Beginning July 1, Medicare will require the use of the new JZ modifier for single-dose containers whenthere are no discarded amounts of a drug/biologic. The JW modifier continues to be required when not all of all the drug/biologic in a single-dose container is used.
| Modifier | Short Descriptor | Long Descriptor |
|---|---|---|
| JW | Discarded drug not administered | 博士ug amount discarded/not administered to any patient |
| JZ | Zero drug wasted | Zero drug amount discarded/not administered to any patient |
In general, the JW and JZ modifier policy applies to all drugs separately payable under Medicare Part B that are described as being supplied in a “single-dose” container or “single-use” package based on FDA-approved labeling.

EffectiveJuly 1, 2023, providers are required to report the JZ modifier to attest no discarded units. Claims that bill for drugs furnished on or afterJuly 1, 2023that do not report the JW or JZ modifier may be subject toprovider audits. |

The use of these modifiers is not appropriate for drugs that are from multiple-dose containers. This includes a drug or biologic in which one National Drug Code (NDC) assigned to its billing code is a multiple-dose container and other NDCs assigned to the same billing code are also single-dose containers.
The JW and JZ modifier policy applies to all providers and suppliers who buy and bill separately payable drugs and biologics under Medicare Part B. The modifiers are required in the physician office setting, hospital outpatient setting, in critical access hospitals and 340B hospitals.
Claims that bill for separately payable drugs under Part B from single-dose containers that don’t report the JW or JZ modifier on or after July 1, 2023, may be subject to audits.
