Summary & Overview
CPT 0676T: Laparoscopic Insertion/Replacement of Diaphragmatic Stimulation Lead
CPT code 0676T captures a laparoscopic procedure to insert or replace an additional lead of a synchronized diaphragmatic stimulation system during the same session as placement of an initial lead, with connection of the lead to an existing pulse generator. This code is clinically significant as synchronized diaphragmatic stimulation is an emerging adjunctive therapy intended to support cardiac function in patients with heart failure, and its proper coding affects facility billing, device management, and post-procedural tracking at a national level. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how the code is defined and applied in clinical practice, where the procedure is typically performed (laparoscopic surgical settings such as hospital ORs or ambulatory surgical centers), and what aspects of billing and policy are relevant for coverage and claims processing. The overview covers common modifiers associated with surgical and implant procedures, contextual clinical considerations related to heart failure treatment, and practical benchmarks and policy updates that payers and providers monitor for novel implantable device procedures. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 0676T describes the laparoscopic insertion or replacement of an additional lead of a synchronized diaphragmatic stimulation system performed at the same session as placement of an initial lead, with connection of that lead to an existing pulse generator. The procedure is intended to support cardiac function in patients with heart failure by providing synchronized diaphragmatic stimulation.
-
Service type: Implantation/revision of an implantable cardiac-related stimulation lead using a laparoscopic approach.
-
Typical site of service: Hospital operating room or ambulatory surgical center (laparoscopic surgical setting).
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with ischemic cardiomyopathy and symptomatic heart failure (NYHA class III) with reduced ejection fraction is referred for implantation of a synchronized diaphragmatic stimulation (SDS) system to improve cardiac function. The patient undergoes general anesthesia in an operating room or ambulatory surgical center. The surgeon performs laparoscopic placement of an initial SDS lead and, at the same session, uses a laparoscopic approach to insert a second diaphragmatic lead and connects it to an existing pulse generator already implanted in a prior procedure. Intraoperative testing confirms lead position and diaphragm stimulation synchronized to the cardiac cycle. The procedure typically requires coordination between cardiac electrophysiology and cardiothoracic or general surgery teams, perioperative anesthesia, device programming personnel, and postoperative monitoring in a PACU or short-stay unit. Indications include refractory heart failure symptoms despite guideline-directed medical therapy and device-based strategies to augment cardiac output. Postoperative workflow includes device interrogation, wound checks, pain control, and discharge planning with device follow-up and cardiac rehabilitation scheduling.

52 | Reduced services | When a reduced service was performed compared to the full procedure. |
53 | Discontinued procedure | If the procedure is started but terminated due to patient instability or unexpected findings. |
62 | Two surgeons | When two surgeons from different specialties shared the operative responsibilities. |
66 | Surgical team | When a surgical team model is used for complex cases requiring multiple surgeons. |
73 | Discontinued outpatient procedure prior to anesthesia or after anesthesia induction | If the outpatient laparoscopic lead insertion is discontinued before completion. |
78 | Return to OR for related procedure during global period | When the patient returns to the OR for a procedure related to the initial 0676T within the global period. |
80 | Assistant surgeon | When an assistant surgeon participates and is appropriately documented. |
81 | Minimum assistant surgeon | When only minimal assistance is provided and meets payer criteria. |
82 | Assistant surgeon when qualified resident not available | When no qualified resident is available and an assistant surgeon is documented. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services | When a recognized non-physician practitioner performed substantive portions of the service under appropriate state law and payer policy. |
