What J9281 covers

J9281 identifies mitomycin instilled into the renal pelvis and calyces, the collecting spaces of the upper urinary tract. Urologists use this local chemotherapy for upper-tract urothelial tumors. Delivery may use a ureteral catheter or nephrostomy tube. The code represents the drug amount, not the access service, and differs from mitomycin injection and bladder instillation codes.

CMS assigns status E, excluding J9281 from the physician fee schedule. When Medicare covers the drug, payment is under another method; the HCPCS file classifies it as a Part B drug, generally priced from CMS quarterly ASP drug pricing files. Coverage is left to the Medicare contractor's judgment. Report units based on mitomycin quantity: one unit represents 1 mg.

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.

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.
