Summary & Overview
CPT 36015: Selective Pulmonary Artery Catheterization for Angiography
CPT code 36015 denotes selective placement of a catheter in a segmental or subsegmental pulmonary artery to perform pulmonary angiography. This procedure is a targeted diagnostic vascular study that visualizes pulmonary arterial branches using radiopaque contrast and fluoroscopy; it is an important tool for diagnosing conditions such as pulmonary embolism, vascular malformations, and other pulmonary vascular pathologies. Nationally, this code represents specialized interventional radiology practice with implications for billing, imaging resource use, and inpatient/outpatient workflow.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a concise overview of clinical context, typical settings for service delivery, and what stakeholders need to know about coding and billing considerations for selective pulmonary arterial catheterization.
Readers will find: a clinical description of the service and when it is used; benchmarks and coverage considerations across major payers where available; common billing and documentation points to support claim submission; and links to related interventional radiology and vascular procedure contexts. Data not available in the input is noted where payer- or policy-specific details are not provided.
Billing Code Overview
CPT code 36015 describes the selective placement of a catheter in a segmental or subsegmental pulmonary artery for the purpose of performing an angiography. Angiography is an X‑ray study of the blood vessels that uses a radiopaque contrast agent to visualize vascular anatomy and identify abnormalities such as stenosis, emboli, or malformations.
-
Service type: Selective pulmonary arterial catheterization for diagnostic angiography
-
Typical site of service: Hospital radiology or catheterization laboratory; may also be performed in inpatient or outpatient interventional suites where fluoroscopic imaging and contrast administration are available.
Clinical & Coding Specifications
Clinical Context
A 64-year-old male with sudden onset pleuritic chest pain and unexplained hypoxemia is admitted from the emergency department. CT pulmonary angiography is inconclusive due to renal insufficiency and contrast allergy. The pulmonary medicine and interventional radiology teams collaborate to evaluate for pulmonary embolism and pulmonary vascular abnormalities. After informed consent, the patient undergoes diagnostic catheter-directed pulmonary angiography with selective placement of a catheter into segmental and subsegmental pulmonary arteries to visualize branch vessels using iodinated contrast under fluoroscopy. The typical clinical workflow includes pre-procedure assessment (coagulation status, renal function, allergy review), vascular access (commonly right femoral or internal jugular venous access), catheter navigation into the main pulmonary artery and selective advancement into segmental/subsegmental branches, injection of radiopaque contrast to obtain angiographic images, interpretation by the performing physician, hemostasis and post-procedure monitoring for bleeding and cardiopulmonary complications. This procedure is performed in an angiography suite or interventional radiology lab with continuous hemodynamic and oxygenation monitoring.
