Summary & Overview
CPT 0915T: Implantation of Cardiac Contractility Modulation–Defibrillation System
Headline: New CPT code 0915T defines implantation of a combined cardiac contractility modulation–defibrillation system
Lead: CPT code 0915T identifies the implant of a permanent cardiac contractility modulation–defibrillation system that includes a pulse generator and two transvenous leads, with fluoroscopic guidance and device programming. The code captures a complex electrophysiology procedure that integrates contractility modulation pacing and defibrillation capability in a single implant.
What the code represents and why it matters: CPT code 0915T formalizes billing for implantation of an emerging combined device that addresses systolic dysfunction and arrhythmia risk. As device-based heart-failure therapies evolve, payers and providers require clarity on coding to support coverage determinations, clinical documentation, and quality measurement nationwide.
Key payers covered: Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare.
What readers will learn: This publication summarizes clinical context for the procedure, typical sites of service, and payer coverage landscape. Readers will find benchmarks for utilization and reimbursement trends where available, relevant policy updates affecting device implantation, and operational considerations for coding and documentation. Data not available in the input include specific ICD-10 diagnosis mappings, associated taxonomies, payer-specific coverage policies, and related codes.
Billing Code Overview
CPT code 0915T describes implantation of a permanent cardiac contractility modulation–defibrillation system consisting of a pulse generator and two transvenous leads. The procedure uses fluoroscopic guidance to place one lead for cardiac contractility modulation pacing and a second lead for defibrillation. After lead placement, the provider evaluates and programs the device to confirm correct function.
-
Service type: Implantation of an implantable cardiac device combining contractility modulation and defibrillation therapy
-
Typical site of service: Hospital inpatient or outpatient surgical setting (electrophysiology lab or cardiac catheterization lab)
Clinical & Coding Specifications
Clinical Context
A typical patient is a 65-year-old with symptomatic heart failure with reduced ejection fraction (HFrEF) who remains symptomatic despite guideline-directed medical therapy. The patient has recurrent exertional dyspnea, reduced exercise tolerance, and documented left ventricular ejection fraction of 25–35% on echocardiogram. After multidisciplinary evaluation, the electrophysiology team schedules implantation of a permanent cardiac contractility modulation–defibrillation system to provide contractility modulation and defibrillation capability.
The clinical workflow begins with pre-procedure evaluation: history and physical, review of current medications (including anticoagulation), device counseling and informed consent, baseline device and ECG testing, and imaging review. In the electrophysiology lab under conscious sedation or general anesthesia, the provider uses fluoroscopic guidance to place two transvenous leads: one for cardiac contractility modulation pacing and one for defibrillation. A pulse generator is implanted in a subcutaneous or submuscular pocket. Intraoperative testing includes lead placement confirmation, defibrillation threshold testing if indicated, and programming of the device. Post-procedure care includes wound assessment, telemetry monitoring for arrhythmia or lead issues, device interrogation, adjustment of programming, and discharge planning with device clinic follow-up and clear activity restrictions.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the work required to implant the device is substantially greater than typical for 0915T due to complexity. |
23 | Unusual anesthesia | Use if general anesthesia is administered for a procedure that is typically performed with local/regional anesthesia. |
51 | Multiple procedures | Use when 0915T is billed in the same session with other distinct procedures. |
52 | Reduced services | Use when the procedure is partially reduced or not completed, but still billed. |
53 | Discontinued procedure | Use when the procedure is started but terminated for reasons such as patient instability. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons during the implant. |
66 | Surgical team | Use when a surgical team approach is documented for the implant. |
78 | Unplanned return to OR following initial procedure | Use for a return to the operating room for related complications occurring during the global period. |
80 | Assistant Surgeon | Use when a surgical first assistant performs documented surgical assistance. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | Use when an APP serves as an assistant at surgery and billing policy allows. |
QK | Medical direction of two, three, or four concurrent anesthesia procedures | Use if the physician medically directs concurrent anesthesia during implant. |
