Summary & Overview
HCPCS C1730: Diagnostic Electrophysiology Catheter, ≤19 Electrodes
HCPCS Level II code C1730 identifies a diagnostic electrophysiology catheter (other than 3D mapping) with 19 or fewer electrodes used in intracardiac electrical recording and pacing during electrophysiology studies. This device-level code matters nationally because it is tied to procedural device reporting, reimbursement for EP diagnostic procedures, and inventory and supply cost management in cardiac electrophysiology programs.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on clinical context for use in EP studies, typical sites of service (hospital outpatient departments, ambulatory surgical centers, and EP labs), and the payer landscape relevant to coverage and claim adjudication. The publication outlines typical billing considerations tied to device reporting and service lines and highlights common modifiers used with device and procedure codes. Where specific payer policies or benchmark data are required, the report notes when underlying data is not supplied.
This summary equips clinical administrators, coding professionals, and revenue cycle staff with the essential background to identify when C1730 applies, understand its role within EP procedural billing, and locate payer policy considerations for further review.
Billing Code Overview
HCPCS Level II code C1730 describes a diagnostic electrophysiology catheter used for cardiac electrophysiology studies with other than 3D mapping and containing 19 or fewer electrodes. The device is intended for intracardiac electrical recording and pacing during diagnostic EP procedures.
Service type: Diagnostic electrophysiology catheter for intracardiac electrical testing.
Typical site of service: Hospital outpatient department, ambulatory surgical center, or cardiac catheterization/electrophysiology lab.
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with symptomatic paroxysmal supraventricular tachycardia (SVT) is referred to the electrophysiology (EP) lab for diagnostic intracardiac mapping and evaluation. The patient presents with palpitations, presyncope, and documented narrow-complex tachycardia on ambulatory monitoring despite guideline-directed medical therapy. After pre-procedure evaluation (history, focused cardiac exam, informed consent, anticoagulation review, and vascular access planning), the patient is brought to a cardiac catheterization/EP procedure suite. Under conscious sedation or monitored anesthesia care, a vascular access site (usually femoral vein) is obtained and intracardiac catheters are introduced. A diagnostic electrophysiology catheter described by C1730 (electrophysiology diagnostic catheter, other than 3D mapping, 19 or fewer electrodes) is positioned in the right atrium, coronary sinus, or His position as needed to record intracardiac electrograms and perform pacing maneuvers. The electrophysiologist performs programmed stimulation, measurements of conduction intervals, and provocation maneuvers to localize arrhythmia substrate. Fluoroscopy and intracardiac recordings guide catheter positioning. Findings may direct a subsequent therapeutic ablation in the same session or at a later date. Typical sites of service are the hospital outpatient department, same-day surgery/ambulatory surgery center, or inpatient electrophysiology lab depending on clinical status and facility triage. Common clinical workflow includes pre-procedure nursing assessment, device and catheter inventory (including C1730), intra-procedure monitoring by cardiology and anesthesia personnel, and post-procedure recovery with telemetry and discharge instructions or admission if complications occur.
