What Q5117 covers

Q5117 identifies trastuzumab-anns, marketed as Kanjinti, a biosimilar medicine that targets HER2. It is given by intravenous infusion in oncology care, including treatment plans for HER2-positive breast cancer and HER2-positive metastatic gastric or gastroesophageal junction cancer. Hospital outpatient departments and physician-based infusion practices may report the drug when they furnish it. The medical record should identify the product and the dose administered.

Medicare assigns this code status E, excluding it from the physician fee schedule; when Medicare covers the drug, payment is made under another method. HCPCS classifies it as a Part B drug, generally priced using CMS’s quarterly Average Sales Price drug files. Coverage is left to the Medicare contractor’s judgment. Each billing unit represents 10 mg of trastuzumab-anns, so report units in 10-mg increments based on the dose furnished.

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.
