CPT 36823 Isolated Limb Perfusion Reimbursement | OpenPayer

Summary & Overview

CPT 36823: Isolated Extracorporeal Regional Chemotherapy Perfusion, Extremity

CPT code 36823 covers the cannulation procedures required to establish isolated extracorporeal circulation for regional chemotherapy perfusion of an extremity, including heated or nonheated techniques. This intervention enables high-dose, localized chemotherapy delivery while minimizing systemic exposure and is used in select oncologic cases such as limb-confined malignancies. Nationally, the code is relevant to surgical oncology, interventional radiology, and perfusion teams because it captures a complex, resource-intensive procedure with implications for facility readiness and perioperative care.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the procedure, typical sites of service, and which major payers commonly cover or adjudicate claims for this service. The publication summarizes benchmarking and reimbursement themes where available, outlines billing considerations tied to procedure complexity, and highlights policy or coverage elements that affect utilization of isolated limb perfusion. The material is intended to inform billing staff, clinical program leads, and policy analysts about the operational and payer-related aspects of delivering regional extracorporeal chemotherapy perfusion.

Billing Code Overview

CPT code 36823 describes the insertion of one or more cannulas into an artery and vein to establish isolated extracorporeal circulation for regional chemotherapy perfusion of an extremity. The service involves diversion of the patient’s blood through an external device that performs the work of the heart and lungs to enable heated or nonheated regional delivery of chemotherapeutic agents with the objective of concentrating treatment in a limb while limiting systemic exposure.

Service Type: Isolated extracorporeal regional chemotherapy perfusion

Typical Site of Service: Inpatient or outpatient surgical or interventional suite, commonly performed in operating rooms or specialized procedural areas equipped for extracorporeal circulation and regional perfusion.

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient with locally advanced extremity soft tissue sarcoma or recurrent melanoma confined to the limb is scheduled for isolated limb perfusion (ILP) with regional chemotherapy. The multidisciplinary workflow begins with preoperative oncology evaluation and imaging to confirm limb-confined disease and vascular access planning. In the operating room or interventional suite, the vascular surgeon or surgical oncologist inserts arterial and venous cannulas into the limb’s major artery and vein under fluoroscopic and ultrasound guidance. An extracorporeal circuit with a pump and heat exchanger is connected to the cannulas to establish isolated extracorporeal circulation of the limb; limb tourniquet or vascular clamps are applied proximally to prevent systemic exposure. Heated or nonheated regional chemotherapeutic agents (for example, melphalan ± tumor necrosis factor in select centers) are circulated through the isolated limb for a defined perfusion time, then the limb is flushed and circulation is restored. Typical perioperative team members include surgical oncology, vascular surgery, anesthesia, perfusionist, and oncology nursing. Post-procedure monitoring focuses on limb perfusion, compartment pressures, local toxicity, and systemic leak surveillance before discharge to inpatient recovery or monitored outpatient care. The typical site of service is an operating room or interventional radiology suite within a hospital with perfusion and oncology support.
