What 96548 covers
This add-on captures additional time spent delivering hyperthermic intraperitoneal chemotherapy during an operation. HIPEC circulates heated chemotherapy through the abdominal cavity, commonly as part of cytoreductive surgery for peritoneal surface malignancy. A surgical oncologist or other physician directing the intraoperative treatment performs the service in an operating room, with the surgical and anesthesia teams supporting the procedure.
Report 96548 with 96547, which covers the initial 60 minutes; it is not a standalone service. Use it for each additional 30-minute period supported by the operative record. Documentation should identify the HIPEC duration beyond the initial period and describe the chemotherapy administration, perfusion, and monitoring. CMS treats this as an add-on billed only with its primary procedure, with payment made within that procedure’s global period.
