Summary & Overview
CPT 33241: Removal of Implantable Defibrillator Pulse Generator
CPT code 33241 represents the surgical removal of an implantable cardioverter-defibrillator (ICD) pulse generator through the existing chest-wall pocket. This procedure is clinically significant nationwide because ICD explantation is performed for device malfunction, battery depletion, system upgrades, or device-related infection, and it involves operating-room resources and postoperative care. Payers commonly involved in coverage and reimbursement decisions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for CPT code 33241, typical sites of service, and the kinds of benchmarks and policy considerations that influence coverage and payment for invasive cardiac device procedures. The publication outlines differences in payer policies, common billing practices, and relevant clinical workflow implications for hospital and outpatient surgical settings. It summarizes common modifiers and coding issues encountered with explantation procedures and highlights areas where coding clarity and documentation are essential. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 33241 describes the surgical removal of an implantable cardioverter-defibrillator (ICD) pulse generator by opening the surgically created pocket in the chest wall and extracting the device. The procedure addresses removal of the generator when it is malfunctioning, depleted, or associated with device-related infection.
-
Service type: Surgical device explantation of an implantable defibrillator pulse generator
-
Typical site of service: Hospital operating room or outpatient surgical center where invasive cardiac device removal is performed
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with ischemic cardiomyopathy and a prior transvenous implantable cardioverter-defibrillator (ICD) placed 6 years ago presents with pocket erosion and device infection manifested by localized erythema, purulent drainage, and positive blood cultures for Staphylococcus aureus. The electrophysiology team evaluates the patient, confirms device-related infection, and schedules removal of the ICD pulse generator. In the operating room or procedure suite, under monitored anesthesia care or general anesthesia, the provider reopens the surgically created subcutaneous pocket in the chest wall, dissects to the device, disconnects and explants the pulse generator, and inspects the pocket and leads. Lead management (retention, partial extraction, or complete lead extraction) is determined by clinical indication and is coded separately if performed. The pocket is irrigated, cultures obtained, and the wound is managed per infection control protocols; temporary pacing or wearable defibrillator management may be arranged until reimplantation is appropriate.
