Summary & Overview

CPT 96547: Intraoperative HIPEC Perfusion, First 60 Minutes

CPT code 96547 reports the first 60 minutes of intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC), a specialty surgical-perfusion procedure in which heated chemotherapy is circulated within the abdominal cavity during an operation. This code captures a high-resource, intraoperative oncologic service that is relevant to tertiary surgical centers and oncology programs nationwide because HIPEC requires coordinated surgical, anesthesia, and perfusion resources and has distinct billing and utilization implications.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for HIPEC, the expected site of service, and the common payer landscape. The publication summarizes benchmark utilization and reimbursement patterns where available, highlights relevant policy and coverage considerations for major commercial plans and Medicare, and outlines coding and billing factors that commonly affect claims adjudication for this intraoperative perfusion service.

The content is intended for health system billing leaders, surgical oncology administrators, and policy analysts seeking a concise national perspective on how CPT code 96547 is used and reimbursed, and what operational implications the code carries for hospitals and specialty surgical programs.

Billing Code Overview

CPT code 96547 describes the initial 60 minutes of intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC). The service is the perfusion of a heated chemotherapy solution into the peritoneal (abdominal) cavity through catheters while the patient is in the operating room during a surgical procedure.

Service type: Surgical intraoperative chemotherapy perfusion
Typical site of service: Hospital operating room / intraoperative setting

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient with recurrent appendiceal mucinous adenocarcinoma presents for cytoreductive surgery with intraoperative hyperthermic intraperitoneal chemotherapy. After a multidisciplinary tumor board review, the patient is taken to the operating room for exploratory laparotomy and maximal cytoreduction (debulking) to remove visible peritoneal disease. Once cytoreduction is complete, peritoneal catheters are positioned and a closed-circuit perfusion system is connected. The surgical team initiates heated chemotherapy perfusion for the first 60 minutes, monitoring core temperature, fluid balance, hemodynamics, and urine output. Anesthesia provides general endotracheal anesthesia with invasive monitoring. The perfusionist and surgical team document start and stop times for the HIPEC phase. Post-perfusion, the abdomen is irrigated and definitive closure is performed. The patient is transferred to the post-anesthesia care unit or intensive care unit for recovery and continued monitoring for hemodynamic changes, renal function, and potential chemotherapy-related toxicities.
