Summary & Overview
CPT 0412T: Removal of Cardiac Contractility Modulation Pulse Generator
CPT code 0412T denotes surgical removal of a cardiac contractility modulation (CCM) pulse generator from a pocket previously created in the right upper chest. As CCM devices are used to modulate cardiac contractility in select heart failure patients, explantation codes like 0412T are important for device lifecycle management, surgical resource planning, and national billing consistency. The code matters nationally because it captures a distinct surgical service tied to specialized cardiac implantable devices and has implications for facility billing and device-related quality tracking.
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 code’s clinical context, typical settings where the service is provided, and the payer landscape addressed. The publication provides benchmarks and mapping for related service lines, notes about common billing modifiers when relevant, and highlights policy considerations that affect coverage and payment for explantation of CCM systems. Clinical teams, coding professionals, and payer policy staff will gain clarity on where 0412T fits within procedural coding for cardiac device management and what items to consider when documenting and submitting claims.

Billing Code Overview
CPT code 0412T describes the removal of a cardiac contractility modulation (CCM) pulse generator from a preexisting pocket in the right upper chest. This procedure involves explantation of an implanted CCM device previously placed to deliver non-excitatory electrical signals to the myocardium.
-
Service type: Device explantation / generator removal
-
Typical site of service: Inpatient or outpatient surgical suite or ambulatory surgery center where implanted cardiac device procedures are performed

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with systolic heart failure who previously had a cardiac contractility modulation (CCM) pulse generator implanted in a subcutaneous pocket in the right upper chest for symptomatic reduction of heart failure symptoms. The patient presents for elective removal of the CCM pulse generator due to reasons such as device malfunction, infection of the pocket, need for device upgrade or replacement, or patient preference. The pre-procedure workflow includes a focused history and physical, review of device interrogation reports, informed consent, surgical site marking, and perioperative antibiotic prophylaxis when indicated. The procedure is performed in an operating room or cardiac electrophysiology lab under monitored anesthesia care or general anesthesia. The surgeon or cardiac electrophysiologist makes an incision over the existing right upper chest pocket, dissects to the device, frees adhesions, disconnects leads or lead connectors per device-specific technique, removes the pulse generator, inspects the pocket for infection or hematoma, irrigates as needed, and closes the pocket in layers. Postoperative workflow includes device interrogation as appropriate, wound care instructions, pain control, and documentation of the reason for removal, findings, and condition of leads if left in place or explanted.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work or resource use substantially exceeds usual for pulse generator removal due to extensive dissection or unexpected complexity. |
51 | Multiple procedures | Use when more than one distinct procedure is performed during the same operative session. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned (e.g., aborted removal). |
53 | Discontinued procedure | Use when the procedure is terminated due to extenuating circumstances prior to completion. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons throughout the procedure. |
66 | Surgical team (team surgery) | Use when a surgical team, such as complex multidisciplinary team, performs the procedure per payer rules. |
78 | Return to OR for related procedure during global period | Use when a related procedure for a postoperative complication requires return to the operating room. |
80 | Assistant surgeon | Use when an assistant surgeon provides services during the procedure. |
81 | Minimum assistant surgeon | Use when minimal assistance is provided and payer accepts this modifier. |
82 | Assistant surgeon (when qualified resident surgeon not available) | Use when an assistant surgeon is needed but resident coverage is not available. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services | Use to indicate services furnished by these non-physician practitioners when allowed by payer. |
CO | Cast-related (specific to orthopedics) | Not typically applicable; included in list but generally not used for CCM removal. |
QX | CRNA service with medical direction by physician | Use when a certified registered nurse anesthetist provides anesthesia under physician direction, if payers require reporting. |
QY | Medical direction of two, three, or four CRNAs by a physician | Use when a physician medically directs multiple CRNAs during anesthesia for the case. |
