What J1447 covers

Tbo-filgrastim (Granix) is a granulocyte colony-stimulating factor used to reduce the duration of severe neutropenia in patients with nonmyeloid cancers receiving myelosuppressive chemotherapy. Oncology clinicians commonly administer it by subcutaneous injection in outpatient cancer clinics and infusion settings. It stimulates neutrophil production as supportive care during chemotherapy. J1447 identifies the drug product rather than the administration service.

Each unit represents 1 mcg of tbo-filgrastim; report units based on the amount administered. CMS excludes J1447 from the physician fee schedule (status E). When Medicare covers the drug, it generally pays it as a Part B drug using CMS quarterly Average Sales Price drug pricing files. Special Medicare coverage instructions apply to the product.

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.
