Summary & Overview
CPT 36013: Right Heart/Main Pulmonary Artery Catheter Introduction for Angiography
CPT code 36013 denotes the introduction of a catheter into the right heart or main pulmonary artery for angiographic evaluation. This procedure is a key diagnostic step in evaluating cardiac and pulmonary vascular conditions, enabling visualization of intracardiac and pulmonary arterial anatomy using radiopaque contrast and X‑ray. Nationally, codes for invasive cardiovascular imaging like 36013 are important for tracking utilization of catheter‑based diagnostics, resource planning in catheterization laboratories, and aligning coverage policies with clinical indications.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The summary outlines coverage contexts readers will see across these payers and highlights typical settings where the service is performed.
Readers will learn operational and clinical context for CPT code 36013, including the clinical purpose of right heart/main pulmonary artery catheter introduction, typical sites of service, and the role of angiography in diagnosis. The publication also provides benchmark-oriented content and policy updates where available. Data not available in the input will be noted explicitly in the relevant sections of the full publication.
Billing Code Overview
CPT code 36013 describes the introduction of a catheter into the right heart or main pulmonary artery, typically performed to obtain angiographic imaging. Angiography uses a radiopaque contrast agent and X‑ray imaging to visualize blood vessels and assess cardiac or pulmonary vascular anatomy and pathology.
Service type: Diagnostic invasive cardiovascular procedure (right heart/main pulmonary artery catheterization for angiography)
Typical site of service: Hospital inpatient or outpatient cardiac catheterization laboratory (cardiac cath lab) or interventional radiology suite, where fluoroscopic imaging and contrast administration are available.
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with progressive exertional dyspnea and suspected pulmonary hypertension is scheduled for right heart catheterization with selective pulmonary angiography. The procedure is performed in a hospital cardiac catheterization lab or an interventional radiology suite. Under conscious sedation or general anesthesia as appropriate, vascular access is obtained (commonly via the right femoral or right internal jugular vein). A guidewire and catheter are advanced into the right atrium, right ventricle, and main pulmonary artery. Contrast is injected to perform angiography of the right heart and pulmonary arterial tree to evaluate pressures, detect pulmonary embolism, assess vascular anatomy, or guide therapeutic interventions. Hemodynamic measurements are recorded, images are obtained under fluoroscopy, and catheters are removed with hemostasis achieved. Typical billing uses 36013 for introduction of the catheter in the right heart or main pulmonary artery when angiographic study of the pulmonary arteries is performed.
