HCPCS code J9282: Mitomycin instillation, intravesical, per 1 mg2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for J9282 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 J9282 covers

This code represents mitomycin administered directly into the bladder, rather than by systemic injection. Urologists and other qualified clinicians typically provide the instillation in an outpatient clinic or hospital setting, often as local chemotherapy for bladder tumors. The drug is delivered through a urinary catheter into the bladder; the drug code is distinct from the code for the instillation service.

Medicare assigns this HCPCS code physician fee schedule status E, meaning CMS excludes it from the physician fee schedule by regulation. When Medicare covers the drug, payment is under another payment method; the HCPCS pricing method identifies it as a Part B drug generally priced through CMS quarterly ASP drug pricing files. The Medicare contractor determines coverage. Report units according to the amount administered: each unit represents 1 mg of mitomycin.
