HCPCS code J9045: Carboplatin, per 50 mg2026 Medicare rate & RVUs

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How the J9045 rate is calculated

Each of J9045’s three RVUs is multiplied by a geographic index (GPCI) for the payment locality, added up, and multiplied by the conversion factor. Drag the indexes or enter a ZIP to see what moves the rate.

Payment rules and modifiers for J9045

J9045 has no global surgery period, no multiple-procedure, bilateral or assistant-at-surgery adjustment, and no professional/technical split. What changes the payment is where the service happens: the place of service on the claim decides whether Medicare pays the office or the facility rate.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
