Summary & Overview
HCPCS C9741: Right Heart Catheterization with Pulmonary Artery Wireless Sensor
HCPCS Level II code C9741 describes right heart catheterization with implantation of a wireless pressure sensor in the pulmonary artery, including measurements, angiography, imaging supervision, interpretation, and report. The code captures a combined diagnostic and therapeutic interventional cardiology service that enables continuous pulmonary artery pressure monitoring for patients with heart failure or other conditions requiring invasive hemodynamic surveillance. Nationally, the code matters because it delineates coverage and billing for an advanced implantable monitoring technology that can influence clinical management and downstream resource use.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find coverage benchmarks, typical sites of service, and a clinical-context overview that explains when this procedure is used and what it includes. The publication summarizes coding scope, common clinical indications, and the service components bundled into C9741 (measurement, angiography, imaging supervision, interpretation, and reporting). It also highlights areas where policy updates and payer coverage criteria commonly affect utilization, prior authorization requirements, and documentation expectations.
This report is intended for healthcare administrators, coding professionals, and payer policy analysts seeking a concise briefing on the clinical purpose and billing scope of HCPCS Level II code C9741.
Billing Code Overview
HCPCS Level II code C9741 describes a right heart catheterization with implantation of a wireless pressure sensor in the pulmonary artery, and includes any type of measurement, angiography, imaging supervision, interpretation, and report. This procedure combines right heart catheter hemodynamic assessment with permanent or implantable wireless sensor placement designed to monitor pulmonary artery pressures.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with chronic heart failure with reduced ejection fraction and recurrent hospitalizations for decompensated heart failure is referred for implantation of a wireless pulmonary artery pressure sensor. The patient has persistent symptoms despite guideline-directed medical therapy and requires ambulatory hemodynamic monitoring to guide diuretic and vasodilator management. The procedure is performed by an interventional cardiology team in a cardiac catheterization laboratory under monitored anesthesia care. Right heart catheterization is performed via femoral or jugular venous access to obtain baseline hemodynamics and pulmonary angiography as indicated. A wireless pressure sensor is implanted in a branch of the pulmonary artery under fluoroscopic guidance with imaging supervision, device deployment, hemodynamic measurements, imaging interpretation, and a written report documented. Post-implantation, the patient is recovered in a monitored setting, provided device education, and scheduled for remote pulmonary artery pressure transmission follow-up and device checks.
