C1825 Implantable Neurostimulator — HCPCS Reimbursement | OpenPayer

Summary & Overview

HCPCS C1825: Implantable Neurostimulator Generator, Carotid Sinus Baroreceptor

HCPCS Level II code C1825 designates an implantable, non-rechargeable neurostimulator generator with carotid sinus baroreceptor stimulation leads. This device-based code is nationally relevant because it identifies a class of implantable cardiac/neuromodulation technology used to manage cardiovascular and autonomic conditions through carotid sinus stimulation. Tracking utilization and coverage for this code informs hospital service planning, device procurement, and payer policy decisions for implant procedures.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical intent and procedural setting, plus benchmarks and policy context where available. The publication highlights coverage considerations across major payers, typical sites of service for implantation procedures, and coding relationships that affect billing workflows. When specific input data is missing, the report notes those gaps explicitly as "Data not available in the input." The content is intended to support coding teams, revenue cycle managers, and policy analysts seeking a national-level understanding of device-oriented HCPCS billing for carotid sinus baroreceptor neurostimulators.

Billing Code Overview

HCPCS Level II code C1825 describes an implantable, non-rechargeable neurostimulator generator with carotid sinus baroreceptor stimulation lead(s). This device is used to deliver targeted electrical stimulation to carotid sinus baroreceptors to modulate autonomic function for therapeutic indications related to blood pressure and cardiovascular regulation.

Service Type: Implantation and management of an implantable neurostimulator generator for carotid sinus baroreceptor stimulation
Typical Site of Service: Hospital inpatient or outpatient surgical setting, ambulatory surgery center, or specialized implant clinic depending on clinical need and procedural complexity

Clinical & Coding Specifications

Clinical Context

A typical patient is a 58-year-old with refractory hypertension despite maximal tolerated medical therapy, often with syncope or labile blood pressure and documented baroreflex dysfunction. After multidisciplinary evaluation including cardiology, neurology, and vascular surgery, the patient undergoes implantation of a non-rechargeable implantable neurostimulator with carotid sinus baroreceptor stimulation leads (C1825). The clinical workflow includes preoperative evaluation (history, medication review, imaging of the carotid arteries such as duplex ultrasound or CTA to assess anatomy and rule out significant stenosis), informed consent, perioperative antibiotic prophylaxis, device implantation in a sterile operating room or hybrid suite, intraoperative testing and programming of the carotid sinus leads to confirm capture and hemodynamic response, and immediate postoperative monitoring for hemodynamic stability and neurologic status.

Typical site of service is an inpatient or hospital outpatient operating room or ambulatory surgical center for implantation. Typical adjunct services include anesthesia (general or monitored anesthesia care), intraoperative device interrogation and programming by a trained clinician or device representative, and postoperative device adjustments in clinic. Usual postoperative care includes short-term observation for bleeding, infection, or neurologic complications, medication adjustments for antihypertensives, and scheduled follow-up for device titration and battery surveillance.
