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.
