Summary & Overview
HCPCS C1900: Lead, Left Ventricular Coronary Venous System
HCPCS Level II code C1900 designates a lead placed in the left ventricular coronary venous system, a component used in cardiac resynchronization and pacing procedures. This code captures a device element critical to therapies for heart failure and conduction abnormalities where left ventricular pacing via the coronary veins is indicated. Nationally, accurate coding for this implant component influences device-related claims, bundling decisions, and payment for complex cardiac device procedures.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find context on clinical use and typical settings for implantation, an outline of common modifiers associated with device and surgical services, and guidance on where to find additional payer-specific coverage information. The publication highlights benchmarks and coding considerations relevant to hospital and electrophysiology service lines, and notes where input data were not provided.
The content is organized to help revenue cycle, coding, and clinical teams understand what C1900 represents, the typical site of service, and the payer landscape to consult for coverage rules. Data not available in the input will be explicitly identified in relevant sections.
Billing Code Overview
HCPCS Level II code C1900 describes a lead placed in the left ventricular coronary venous system. This represents a cardiac device implant component used to deliver pacing or resynchronization therapy to the left ventricle via the coronary venous anatomy.
Service Type: Cardiac implantable lead placement (left ventricular coronary venous lead)
Typical Site of Service: Hospital operating room, cardiac catheterization lab, or electrophysiology suite

Clinical & Coding Specifications
Clinical Context
A 72-year-old patient with ischemic cardiomyopathy and symptomatic heart failure is scheduled for cardiac resynchronization therapy with an implanted left ventricular lead placed in the coronary venous system (C1900). The patient has New York Heart Association (NYHA) class III symptoms, a left bundle branch block on ECG, and an ejection fraction of 28% documented on echocardiogram. The electrophysiology team performs pre-procedure device interrogation and imaging review, obtains informed consent, and ensures peri-procedural anticoagulation management. In the electrophysiology laboratory or cardiac catheterization suite, the patient undergoes transvenous placement of a coronary sinus lead into an appropriate lateral or posterolateral coronary vein via the subclavian or cephalic venous approach. Lead positioning is confirmed with fluoroscopy and electrical measurements; the lead (C1900) is secured and connected to a cardiac resynchronization therapy device. Post-procedure, the patient is observed in a recovery area with chest radiography and device testing prior to discharge or admission for overnight monitoring depending on clinical status.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural service | When work or complexity of lead placement is substantially greater than usual (extensive adhesiolysis, multiple vein attempts) |
51 | Multiple procedures | When additional distinct procedural charges are billed the same day by the same provider |
52 | Reduced services | When a planned portion of the procedure is partially reduced or not completed |
53 | Discontinued procedure | When the lead placement is started but aborted for patient safety before completion |
54 | Surgical care only | When the provider bills only the intraoperative portion and another bills pre/postoperative care |
55 | Postoperative management only | When the provider bills only routine postoperative follow-up related to the lead/device |
62 | Two surgeons | When two surgeons with distinct specialties simultaneously perform critical portions of the procedure |
74 | Discontinued outpatient procedure prior to anesthesia | When the outpatient lead placement is canceled after preparation but before anesthesia/admission |
80 | Assistant at surgery | When a surgical assistant performs part of the operative procedure under direction |
81 | Minimum assistant at surgery | When a minimum assistant presence is required and documented |
82 | Assistant not available | When an assistant is not available and this impacts billing per payer policy |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | When a qualified advanced practice clinician serves as the surgical assistant and local payer allows AS |
