Check a contract rate as a % of Medicare · J9350 nationwide

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

What J9350 covers

Mosunetuzumab-axgb is an intravenous bispecific antibody that links CD20-positive B cells with CD3-positive T cells. It is used for adults with relapsed or refractory follicular lymphoma after at least two prior systemic therapies. Oncology clinicians administer it by infusion, using step-up dosing and monitoring for reactions such as cytokine release syndrome and neurologic toxicity.

J9350 identifies the drug quantity, not the infusion service. Each billing unit represents 1 mg of mosunetuzumab-axgb, so units are based on the administered dose. CMS assigns physician fee schedule status E, excluding the code from that schedule; when Medicare covers the drug, payment is under another method. CMS classifies it as a Part B drug, generally priced from quarterly Average Sales Price files when covered. The Medicare contractor determines coverage.
