HCPCS code J9041: Bortezomib injection, per 0.1 mg2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for J9041 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 J9041 covers

Bortezomib is an antineoplastic drug used in treatment regimens for multiple myeloma and mantle cell lymphoma. Oncology clinicians administer it by subcutaneous or intravenous injection, commonly in outpatient cancer clinics or hospital settings. J9041 identifies the bortezomib drug quantity, not the administration service.

J9041 is excluded from the Medicare physician fee schedule under status E. When Medicare covers the drug, payment is made under another payment method; HCPCS classifies it as a Part B drug, generally priced using CMS quarterly Average Sales Price drug files. Coverage is left to the Medicare contractor’s judgment. Each unit represents 0.1 mg of bortezomib, so 1 mg is reported as 10 units. Report units based on the drug amount administered and document the dose and product used.

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.
