HCPCS code J9050: Carmustine injection, per 100 mg2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for J9050 in California.

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

What J9050 covers

Carmustine is an alkylating chemotherapy drug given by intravenous infusion. Oncology practices use it in treatment plans for certain brain tumors and blood cancers, including lymphoma and multiple myeloma. This code identifies the injectable drug, not carmustine wafers placed surgically in the brain. Select the drug code that matches the product supplied; J9052 identifies an Accord carmustine product.

One unit represents 100 mg of carmustine, so reported units reflect the administered amount divided by 100 mg. CMS excludes J9050 from the physician fee schedule under status E. When Medicare covers the drug, it pays under another method; HCPCS pricing identifies it as a Part B drug generally paid from CMS’s quarterly ASP drug pricing files. Special Medicare coverage instructions apply.
