When reporting the JW modifier for discarded drug, the medical record must clearly show the amount administered and the amount wasted.
Medical record must document prior anthracycline therapy for patients receiving albumin-bound paclitaxel, or clearly document a clinical contraindication to anthracycline therapy.
For claims with no discarded amounts from single-dose containers or single-use packages, include the JZ modifier as evidence on the claim (effective July 1, 2023).
Document dose and frequency as consistent with the FDA label or recognized compendia for the indication (including citations to the compendia if used for off-label indications).

Paclitaxel administered intravenously is covered for antineoplastic (cancer) indications when used in accordance with the FDA-approved labeling.
Off-label uses of paclitaxel are covered when supported by recognized compendia (e.g., NCCN, AHFS, Clinical Pharmacology, Lexi-Drugs, Micromedex) and dosing/frequency follow those compendia.
Albumin-bound paclitaxel (Abraxane) is covered when prior therapy included an anthracycline unless anthracycline therapy is clinically contraindicated.
When a molecular panel of 5–50 genes is ordered, bill the appropriate panel CPT code (81445, 81449, 81450, or 81451) instead of submitting individual single-gene CPT codes.
When 51 or more genes are ordered for molecular biomarkers, bill the appropriate large-panel CPT code (81455 or 81456) rather than individual gene codes.
When a panel contains more than one but fewer than five genes, use the corresponding existing panel CPT code or CPT 81479 (unlisted molecular pathology procedure) if no specific panel CPT exists.
