Summary & Overview

CPT 0409T: Cardiac Contractility Modulation Pulse Generator Implantation

CPT code 0409T covers implantation, or removal and replacement, of a cardiac contractility modulation (CCM) pulse generator with electrode placement on the right ventricular septum and the atrium, including contractility evaluation and programming. The code is nationally relevant as CCM is an advanced device therapy for patients with moderate–to–severe congestive heart failure who remain symptomatic despite optimal medical therapy, and its use affects device utilization, hospital outpatient and ambulatory surgical workflows, and payer coverage decisions. Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find a concise clinical and coding overview, typical sites of service and service classification, and the payer landscape for coverage and reimbursement context. The publication summarizes benchmarks for utilization and reimbursement where available, highlights policy and coverage considerations, and outlines clinical context for appropriate use of CCM therapy. Data not available in the input will be clearly identified where relevant.

Billing Code Overview

CPT code 0409T describes the implantation or removal and replacement of a cardiac contractility modulation (CCM) pulse generator. The procedure involves creating a subcutaneous pocket in the right upper chest, attaching electrodes to the right ventricular septum and the atrium, and supplying a pulse generator that delivers CCM therapy to increase the strength of cardiac contractions for patients with moderate–to–severe congestive heart failure who remain symptomatic despite optimal medical therapy. The code explicitly includes evaluation of contractility if performed, device programming, and the generator.

Service type: Implantation of an implantable cardiac device (cardiac contractility modulation pulse generator) with lead placement and programming
Typical site of service: Hospital outpatient department or ambulatory surgical center; inpatient setting if clinically indicated

Clinical & Coding Specifications

Clinical Context

A 68-year-old male with ischemic cardiomyopathy and New York Heart Association (NYHA) Class III heart failure despite guideline-directed medical therapy is referred for implantation of a cardiac contractility modulation (CCM) system. The patient undergoes pre-procedure evaluation including cardiology clinic assessment, echocardiography documenting reduced left ventricular ejection fraction (LVEF 25–35%), medication review confirming maximally tolerated beta-blocker, ACE inhibitor/ARB/ARNI, and diuretic therapy, and device counseling. On the day of service the patient presents to the electrophysiology lab in an outpatient or short-stay setting. Under conscious sedation or monitored anesthesia care the provider creates a right upper chest subcutaneous pocket, implants the CCM pulse generator, and attaches leads to the right ventricular septum and right atrium transvenously. Intra-procedural testing includes measurement of lead parameters, evaluation of contractility response if performed, and device programming. Post-procedure monitoring occurs in recovery with telemetry and a brief observation period prior to discharge the same day or after an overnight stay if medically indicated. Follow-up visits include device interrogation, wound check, and heart failure management in the heart failure clinic.

Coding Specifications

Modifier	Description	When to Use
`52`	Reduced services	Use when the CCM implantation is partially reduced or fewer components are performed than described by `0409T`.
`53`	Discontinued procedure	Use when the implantation was started but discontinued due to unforeseen complications before completion.
`62`	Two surgeons	Use when two surgeons share equally in the performance of the CCM implantation.
`66`	Surgical team	Use when a surgical team approach is used with multiple specialists beyond a single surgeon.
`78`	Unplanned return to the OR following initial procedure	Use when the patient returns to the operating room for a related procedure during the global period.
`79`	(Not in provided list)	Data not available in the input.
`76`	(Not in provided list)	Data not available in the input.
`51`	Multiple procedures	Use when other distinct procedures are billed on the same day with CCM implantation; append to secondary codes per payer rules.
`22`	Increased procedural services	Use when the procedure requires substantially greater work than typical, documented and justified.
`26`	Professional component	Use when reporting only the physician interpretation/component separate from technical services (rare for implant but applicable to standalone device programming/interpretation).
`54`	Surgical care only	Use when the surgeon provides only the surgical portion and another provider manages pre/post-operative care.
`55`	Post-operative management only	Use when the surgeon provides only post-operative care after the implantation performed by another provider.
`56`	Pre-operative management only	Use when the surgeon provides only pre-operative care.

Taxonomy Code	Specialty	Notes
`207RP0000X`	Cardiac Electrophysiology	Electrophysiologists commonly perform CCM device implantation.
`208000000X`	Cardiovascular Disease	Heart failure cardiologists evaluate eligibility and manage peri-procedural heart failure care.
`207L00000X`	Internal Medicine – Cardiology	General cardiologists participate in device selection and follow-up.
`363LA2200X`	Physician Assistant	Advanced practice providers often assist in pre- and post-procedure care and device checks.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`I50.22`	Chronic systolic (congestive) heart failure	Primary indication for CCM therapy in patients with reduced ejection fraction and persistent symptoms despite medical therapy.
`I50.23`	Acute on chronic systolic (congestive) heart failure	Relevant when a patient with chronic systolic HF presents with acute decompensation but may still be considered for CCM if stabilized.
`I50.9`	Heart failure, unspecified	Used when heart failure is documented but subtype not specified; supports need for advanced therapies including CCM.
`I42.0`	Dilated cardiomyopathy	Common underlying etiology for systolic heart failure and CCM candidacy.
`I25.10`	Atherosclerotic heart disease of native coronary artery without angina pectoris	Ischemic cardiomyopathy is a frequent contributor to reduced LVEF prompting CCM consideration.
