Summary & Overview
CPT 96548: HIPEC Additional 30 Minutes Intraoperative Perfusion
CPT code 96548 designates an additional 30 minutes of intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) delivered after a first 60 minutes of perfusion. This time-based add-on code captures extended perfusion time during a surgical procedure and is relevant for care of patients with peritoneal malignancies where heated intraperitoneal chemotherapy is used intraoperatively. Nationally, correct use of this code affects facility and professional billing for complex oncologic surgical procedures and can influence resource accounting for operating room time and chemotherapy delivery.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of clinical context for HIPEC, the service setting and procedural implications, and an outline of common modifiers used with this type of time-based intraoperative service. The content highlights benchmarks for utilization, typical billing considerations, and recent policy or coding clarifications where available.
This summary is intended to orient billing staff, surgical teams, and revenue cycle professionals to the purpose of CPT code 96548, the clinical scenario it represents, and the payer landscape affecting reimbursement and documentation practices. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 96548 describes an additional 30 minutes of intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) delivered after an initial 60 minutes. The service is the perfusion of a heated chemotherapy agent into the abdominal cavity through catheters during an operation.
Service type: Intraoperative chemotherapy perfusion (HIPEC), extended time
Typical site of service: Operating room / inpatient surgical setting
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with recurrent appendiceal mucinous neoplasm and peritoneal carcinomatosis is taken to the operating room for cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy (HIPEC). After the surgical oncologist performs cytoreduction and completes the initial HIPEC perfusion for 60 minutes, an additional 30 minutes of perfusion is required due to operative judgment for improved drug exposure and residual microscopic disease. The perfusion is delivered through abdominal catheters with the perfusate heated to therapeutic temperatures; the anesthesia team manages physiologic parameters and the perfusionist monitors flow and temperature. Post-perfusion, the abdomen is irrigated, catheters are removed, and the patient is transferred to the intensive care unit for close monitoring of hemodynamics, fluid shifts, and potential organ dysfunction.

| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier used | Standard reporting when no special circumstances apply |
22 | Increased procedural services | Use when work required is substantially greater than typical due to complexity during HIPEC |
