Summary & Overview
CPT 0921T: Removal of Single Transvenous Defibrillation Lead
CPT code 0921T covers the removal of a single transvenous defibrillation lead from a permanent cardiac contractility modulation–defibrillation system. This procedure is part of device management and extraction services for patients with implanted cardiac devices that incorporate contractility modulation and defibrillation capabilities. Nationally, accurate coding for lead extraction affects claims processing, quality tracking, and device-related procedural reporting.
Key payers in the national landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of the clinical context for lead extraction, the common sites where the procedure is performed, and payer coverage considerations. The publication outlines benchmark metrics, applicable billing modifiers, and policy updates relevant to device extraction procedures where data is available.
The content provides practical reference material for billing, revenue cycle, and clinical teams responsible for documenting and submitting claims for transvenous lead removal. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 65-year-old with a previously implanted permanent cardiac contractility modulation–defibrillation (CCM‑DF) system who presents with lead malfunction, pocket infection, lead fracture, or system upgrade needs. The patient has symptoms such as device shocks, inappropriate sensing, or recurrent infections, and device interrogation confirms a single transvenous defibrillation lead requires removal. The procedure is performed in a cardiac electrophysiology laboratory or hybrid operating room under conscious sedation or general anesthesia depending on clinical risk and anticipated extraction complexity. Pre-procedure workflow includes history and physical, device interrogation, chest radiography or CT to define lead course and potential adhesions, informed consent, review of anticoagulation, and coordination with cardiovascular surgery and anesthesia teams. Intra-procedure steps include vascular access, fluoroscopic guidance, locking stylet or sheath placement, lead extraction using manual traction or powered extraction tools as indicated, hemodynamic monitoring, and immediate management of complications (tamponade, vascular injury). Post-procedure care includes monitoring in a step-down or inpatient setting, repeat imaging as indicated, wound care, and decisions on device reimplantation or alternative therapy once infection is controlled or lead issues are resolved.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical due to extensive adhesions, prolonged extraction time, or unexpected complexity. |
23 | Unusual anesthesia | Use when general anesthesia is required for an otherwise typically local/sedation procedure due to patient condition or extraction complexity. |
51 | Multiple procedures | Use when the lead removal is billed on the same date as other unrelated procedures; append per payer rules. |
52 | Reduced services | Use when a planned extraction is partially performed or aborted with reduced work (e.g., abandoned attempt). |
53 | Discontinued procedure | Use if the extraction is started but stopped due to intraoperative complication preventing completion. |
62 | Two surgeons | Use when two surgeons with different specialties (electrophysiology and cardiothoracic) work together as co-surgeons. |
66 | Surgical team complexity | Use when a surgical team approach is required for complex extraction with documented team involvement. |
78 | Unplanned return to OR | Use when the patient returns to the operating room for related procedure during the postoperative period due to complication of the extraction. |
80 | Assistant surgeon | Use when an assistant surgeon performs part of the procedure and payer recognizes this modifier. |
81 | Minimum assistant surgeon | Use when a minimal assistant role is documented and allowed by payer rules. |
82 | Assistant surgeon (when qualified resident not available) | Use when an assistant surgeon is needed and no qualified resident is available. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services in lieu of physician | Use when an advanced practice clinician performs billable portions as permitted by payer policy. |
QX | CRNA service with qualified anesthesia physician | Use when a certified registered nurse anesthetist furnishes anesthesia under medical direction and payer requires this modifier. |
QY | Medical direction of two, three, or four concurrent anesthesia procedures | Use when the anesthesiologist medically directs concurrent anesthesia services for multiple patients. |
| Taxonomy Code | Specialty | Notes |

| 207RR0500X | Cardiovascular Disease | Interventional cardiologists or general cardiologists with electrophysiology training may perform or assist. |
| 2080P0206X | Surgery - Cardiothoracic | Cardiothoracic surgeons manage complex extractions or surgical complications (e.g., vascular injury). |
| 363L00000X | Anesthesiology | Anesthesiologists provide general or monitored anesthesia care during extraction. |
| 367HP0000X | Physician Assistant | PAs often assist in perioperative care and intraoperative support under supervision. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |

I49.01 | Ventricular fibrillation | Indication for an implanted defibrillation-capable system and potential reason for lead dysfunction or shocks prompting extraction. |
I50.22 | Chronic systolic (congestive) heart failure | Underlying heart failure frequently treated with device therapies; lead removal may be required for malfunction or infection. |
T82.7XXA | Infection and inflammatory reaction due to other cardiac and vascular devices, implants and grafts, initial encounter | Pocket or device infection is a common indication for lead extraction. |
T82.221A | Fracture of cardiac electrode, initial encounter | Mechanical lead fracture is a direct indication for lead removal and replacement. |
