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.

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.
