Summary & Overview
CPT 33233: Pacemaker Pulse Generator Removal
CPT code 33233 denotes the surgical removal of a permanent pacemaker pulse generator through reopening the device pocket. This code is nationally relevant because pacemaker revisions and extractions are common components of cardiac device management, affecting hospital surgical throughput, device lifecycle costs, and post-procedure care pathways. Coverage and reimbursement policies for device removal influence provider coding, site-of-service decisions, and billing patterns across payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of typical clinical context for generator removal, common sites of service, and the operational implications for surgical and electrophysiology teams. The publication also summarizes payer coverage considerations and coding benchmarks where available, highlights applicable documentation elements, and outlines areas where policy updates can affect authorization and payment. This briefing is designed to inform hospital administrators, coding professionals, and cardiology service leaders about the clinical and billing significance of CPT code 33233 at a national level.
Billing Code Overview
CPT code 33233 describes a surgical procedure in which the provider reopens the cardiac device pocket and removes a permanent pacemaker pulse generator. The service type is a surgical device removal procedure. The typical site of service is an operating room or cardiac electrophysiology procedural suite, often performed in an inpatient or outpatient surgical setting depending on clinical need.

Clinical & Coding Specifications
Clinical Context
A 78-year-old male with a previously implanted permanent dual‑chamber pacemaker presents to the electrophysiology clinic with suspected device malfunction and pocket infection. The patient reports erythema, tenderness, and purulent drainage at the left subclavian generator pocket, and device interrogation demonstrates loss of sensing from the pulse generator. The clinical workflow includes preoperative evaluation with history and physical, device interrogation, chest radiograph to confirm lead position, informed consent explaining device removal, perioperative antibiotic administration, and scheduling for generator explantation. In the operating room or cardiac catheterization lab under monitored anesthesia care or general anesthesia, the provider opens the pacemaker pocket, removes the permanent pacemaker pulse generator (33233), cultures the pocket, irrigates, and either closes the pocket for delayed reimplantation or coordinates lead management and reimplantation as clinically indicated. Postoperative care includes wound management, documentation of device removal, notification to the device manufacturer for device return, and updated coding and billing with any applicable modifiers.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier — default billing indicator | Use when no additional modifier applies and standard billing is appropriate |
52 | Reduced services | Use when the generator removal is partially performed or limited compared to the full procedure |
53 | Discontinued procedure | Use when the procedure is begun but terminated for patient-related reasons before completion |
59 | Distinct procedural service | Use when a separately identifiable service unrelated to the generator removal is performed on the same day |
62 | Two surgeons | Use when another surgeon is required to assist and both are billing for distinct surgical services |
63 | Procedure performed on infants less than 4 kg | Use rarely for neonates/infants meeting weight criteria when technique differs |
78 | Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period | Use when urgent re‑exploration of the pocket is required after an earlier generator removal |

| 207RP0000X | Cardiac Electrophysiology | Electrophysiologists commonly perform device explantation and lead management |
| 207RC0000X | Cardiovascular Disease | Interventional cardiologists or cardiologists may manage or coordinate device removal |
| 363LF0000X | Nurse Practitioner — Cardiology | Advanced practice clinicians frequently assist in pre/postoperative device management |
| 2084P0800X | Thoracic Surgery | Thoracic or cardiothoracic surgeons may be involved for complex explantations or infections |
| 363LA2200X | Physician Assistant — Cardiology | Physician assistants commonly assist in the perioperative workflow |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
T82.7XXA | Infection and inflammatory reaction due to other cardiac and vascular devices, implants and grafts, initial encounter | Common indication for generator removal when pocket infection is present |
T82.115A | Displacement of cardiac pacemaker lead, initial encounter | Lead displacement may accompany generator malfunction prompting device removal or revision |
I49.5 | Sick sinus syndrome | Underlying rhythm disorder for which a pacemaker had been implanted; removal may occur for device failure or upgrade |
I44.2 | Atrioventricular block, complete | A common underlying indication for prior pacemaker therapy; generator removal occurs when malfunction or infection necessitates explantation |
Z45.01 | Encounter for adjustment and management of cardiac pacemaker | Relevant to pre‑ and post‑procedure device management visits |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
