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.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	When reporting only the physician interpretation of diagnostic images separate from technical services (rare for angiography billing split).
`50`	Bilateral procedures	When bilateral pulmonary angiography elements are specifically reported and payer requires bilateral modifier (uncommon).
`52`	Reduced services	When the procedure is partially reduced or not completed as planned (e.g., limited selective catheterization).
`53`	Discontinued procedure	When the procedure is terminated due to patient instability before completion.
`59`	Distinct procedural service	When another unrelated procedure is performed the same day and needs to be identified as separate.
`62`	Two surgeons	When two surgeons share responsibility for a complex procedure per payer policy.
`76`	Repeat procedure by same physician	When the physician repeats the angiography procedure during the same episode.
`78`	Unplanned return to operating/procedure room by same physician following initial procedure for a related complication.
`TC`	Technical component	When reporting only the technical component (facility/technical staff, equipment) separate from physician interpretation.
`22`	Increased procedural service	When work, time, or complexity substantially exceeds that usually required.
`53`	Reduced services	When the service was started but discontinued; used for aborted procedures (listed here for emphasis).
