What J9045 covers
Carboplatin is an antineoplastic drug given by intravenous infusion, commonly as part of chemotherapy for cancers such as ovarian or lung cancer. Oncology practices and hospital outpatient departments report the drug when it is administered; the drug code represents the medication, not the infusion service. Carboplatin may be used in combination regimens, including regimens with paclitaxel or docetaxel.
Each J9045 unit represents 50 mg of carboplatin, so the administered dose is counted in 50 mg increments. CMS assigns this code physician fee schedule status E, meaning it is excluded from the physician fee schedule; when Medicare covers the drug, payment is made under another method. For a covered Part B drug, CMS generally uses its quarterly Average Sales Price drug pricing files. Special Medicare coverage instructions apply.

What documentation supports the reported units?
Document the carboplatin administered and the dose in milligrams so the reported units correspond to 50 mg each.
Should J9045 be used for a different platinum drug?
No. Report J9045 for carboplatin; select the drug code that matches the medication actually administered.
