How do you bill the JW Modifier for the drug amount discarded and/or not administered to the patient if the drug has a Medically Unlikely Edit (MUE)?

The JW modifier is meant for drug wastage that wasn't given to the patient, only from single dose vial drugs. The provider must submit the drug and dosage administered on one claim line and include the waste on another claim line appending the JW modifier.

The JW modifier will not bypass CMS Medically Unlikely Edits (MUE). If services are denied, a provider will need to appeal.
