What 96547 covers

Code 96547 describes the initial hour of intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC), in which heated chemotherapy is circulated within the abdominal cavity. It is typically performed in the operating room by a surgical oncology team after cytoreductive surgery for peritoneal surface malignancy. The treatment is distinct from a routine chemotherapy injection or an infusion through an implanted pump.

Report 96547 with a primary procedure; it is not a stand-alone service. Record the perfusion time and operative details showing that HIPEC was performed. When perfusion continues beyond the initial hour, use 96548 for each additional 30 minutes. CMS treats this add-on payment within the primary procedure’s global period, so the HIPEC service is paid in relation to that operation rather than as an independent procedure.

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.
