Summary & Overview
CPT 0918T: Implantation of Dual Transvenous Leads for CCM-Defibrillation System
CPT code 0918T represents the implantation of dual transvenous leads — one lead for pacing and one for defibrillation — as part of a cardiac contractility modulation–defibrillation system. The code captures a complex, image-guided procedure that includes fluoroscopic lead placement, intraoperative testing, and device programming. Nationally, this service is clinically significant because it combines heart failure contractility modulation with defibrillation capability in patients who may require both therapies, and it intersects cardiology, electrophysiology, and device-management workflows.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise synthesis of what the code denotes, the clinical and procedural context, and what to expect in terms of site-of-service patterns. The publication outlines benchmarks where available, summarizes relevant policy and coverage considerations, and situates the procedure in clinical practice for electrophysiology teams and hospital device programs.
This overview is intended for clinicians, coding and reimbursement staff, and policy analysts seeking a clear, national-level summary of CPT code 0918T, including clinical scope, service setting implications, and the types of operational considerations that accompany advanced cardiac device implantation.
Billing Code Overview
CPT code 0918T describes the implantation of dual transvenous leads for a cardiac contractility modulation–defibrillation system. The procedure involves placing one lead for cardiac pacing and one lead for defibrillation using fluoroscopic guidance, followed by intraoperative evaluation and programming to confirm lead function and device performance.
Service Type: Implantation of cardiac device leads (transvenous pacing and defibrillation leads)
Typical Site of Service: Electrophysiology laboratory or cardiac catheterization lab in an inpatient or outpatient hospital setting or specialized ambulatory surgical center
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with ischemic cardiomyopathy and symptomatic heart failure (NYHA class III) despite optimal medical therapy is scheduled for implantation of a cardiac contractility modulation–defibrillation system. The patient has a reduced left ventricular ejection fraction and documented episodes of life‑threatening ventricular arrhythmia or high risk for sudden cardiac death. The electrophysiology team performs the procedure in a cardiac catheterization or electrophysiology laboratory under conscious sedation or general anesthesia. Using fluoroscopic guidance, the operator accesses the venous system, advances and positions two transvenous leads — one positioned to deliver contractility modulation pacing to the right ventricular septum or interventricular septum and a second high‑voltage lead positioned for defibrillation (typically in the right ventricle). Lead thresholds, sensing, and impedance are measured, and the ICD and CCM functions are programmed and tested. Post‑implant chest radiography confirms lead positions and device pocket integrity. Typical documentation includes preoperative diagnosis, informed consent, device model and lead types, fluoroscopy time, intraoperative testing values, programming settings, and discharge instructions.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the procedure requires substantially greater work than typical due to complexity (document rationale and time). |
51 | Multiple procedures | Use when other distinct CPT procedures are billed on the same day in addition to the implant. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned (document why). |
53 | Discontinued procedure | Use when the procedure is terminated due to patient-related or surgical factors. |
62 | Two surgeons | Use when two surgeons with different NPI numbers share primary surgical duties. |
66 | Surgical team | Use when a surgical team (multiple surgeons) is involved per payer rules. |
78 | Return to OR for related procedure during postoperative period | Use for a return to the operating room for a complication related to the implant during the global period. |
80 | Assistant surgeon | Use when an assistant surgeon performs part of the procedure and billing rules allow. |
81 | Minimum assistant surgeon | Use when a minimum assistant surgeon performs a minor portion per payer policies. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | Use when an advanced practice clinician acts as the surgical assistant (payer-dependent). |
