Summary & Overview
CPT 0408T: Cardiac Contractility Modulation System Implantation
CPT code 0408T identifies the implantation, removal, or replacement of a cardiac contractility modulation (CCM) system, including generator placement in a right upper chest pocket, electrode attachment to the right ventricular septum and atrium, and any contractility evaluation and programming performed. The code captures the complete procedural service, encompassing the generator and electrodes. This service is clinically significant as CCM offers a therapeutic option for patients with moderate–to–severe congestive heart failure who remain symptomatic despite optimal medical therapy, and its use has implications for device utilization, outpatient procedural workflows, and payer coverage policies nationwide.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for CCM implantation, standard sites of service, and the typical service type. The publication summarizes national benchmarking considerations, payer policy themes, and coding nuances relevant to documentation and claims submission. It also outlines where data was available for benchmarking and where input data was not provided. This resource is designed for health system revenue leaders, hospital administrators, clinical coders, and policy analysts seeking a focused briefing on CPT code 0408T and its operational and coverage implications.
Billing Code Overview
CPT code 0408T describes the implantation, removal, or replacement of a cardiac contractility modulation (CCM) system. The procedure includes creating a generator pocket in the right upper chest, attaching electrodes on leads that deliver electrical impulses to the right ventricular septum and the atrium, and may include evaluation of contractility and programming. The intended clinical purpose is to increase the strength of the heart's contractions for patients with moderate–to–severe congestive heart failure who are not controlled by optimal medical therapy.
-
Service type: Implantation or replacement of an implantable cardiac device (cardiac contractility modulation system)
-
Typical site of service: Hospital outpatient department or ambulatory surgery center; may also be performed in a cardiac catheterization laboratory
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with ischemic cardiomyopathy and left ventricular ejection fraction 30% remains symptomatic with New York Heart Association (NYHA) class III heart failure despite guideline-directed medical therapy including beta-blocker, ACE inhibitor/ARB/ARNI, mineralocorticoid receptor antagonist, and diuretics. The cardiology team evaluates him for device-based therapies and determines he is not a candidate for cardiac resynchronization therapy. The provider schedules implantation of a cardiac contractility modulation (CCM) system to deliver non-excitatory biphasic electrical signals to the right ventricular septum and atrium to improve myocardial contractility.
The clinical workflow includes pre-procedure evaluation (history, physical, medication reconciliation, device counseling, informed consent, baseline ECG and echocardiography), periprocedural antibiotics, implantation of the CCM generator in a right upper chest subcutaneous pocket, lead placement to the right ventricular septum and atrium with intraoperative testing of electrical parameters and contractility assessment if performed, device programming, hemostasis and wound closure, immediate post-procedure monitoring for arrhythmia or lead complications, device interrogation and programming adjustments prior to discharge, and scheduled follow-up visits for device checks and heart failure management. Typical site of service is an inpatient or outpatient hospital-based electrophysiology or cardiology procedure suite with monitored recovery. Payors commonly involved include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.

62 | Co-surgery by two surgeons | Use when two surgeons of different specialties perform distinct portions of the implantation concurrently. |
66 | Surgical team | Use for a documented surgical team approach during complex CCM implantation (per institutional policy). |
78 | Return to OR for related procedure after prior anesthesia | Use when patient returns to the operating room for a related CCM surgical procedure during the postoperative global period. |
