CPT 93582: Transcatheter Closure of Patent Ductus Arteriosus

CPT code 93582 denotes the percutaneous transcatheter closure of a patent ductus arteriosus (PDA), a congenital connection between the pulmonary artery and aorta. This minimally invasive interventional cardiology procedure provides an alternative to open surgical ligation and is significant for reducing recovery time and resource utilization for pediatric and adult congenital heart patients. Nationally, transcatheter PDA closure is an established treatment within congenital heart disease programs and cardiac catheterization laboratories.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication covers payer coverage considerations and typical site-of-care configurations for this service across major commercial and public payers.

Readers will find an overview of clinical context for PDA closure, typical sites of service and care settings, common billing modifiers relevant to procedure reporting, and guidance on coding nomenclature. Where available, benchmarking information and policy updates affecting authorization and coverage processes are summarized. Data gaps in the input are noted as unavailable; the content focuses on the procedural description, payer landscape, and operational implications for facilities and billing teams.

Billing Code Overview

CPT code 93582 describes a percutaneous, catheter-based closure of a patent ductus arteriosus (PDA), a congenital vascular connection between the pulmonary artery and the aorta. The procedure is performed by inserting a catheter through the skin and advancing it through the vascular system to deploy a closure device at the PDA, achieving occlusion without an open surgical approach.

Service type: Interventional cardiology procedure — transcatheter PDA closure

Typical site of service: Cardiac catheterization laboratory or interventional radiology suite

Clinical & Coding Specifications

Clinical Context

A typical patient is an infant or young child diagnosed with a hemodynamically significant patent ductus arteriosus (PDA) presenting with signs of congestive heart failure, poor weight gain, tachypnea, or a continuous murmur on exam. The cardiology team schedules a transcatheter device closure under general anesthesia in a pediatric cardiac catheterization laboratory. Vascular access is obtained percutaneously (commonly femoral vein and/or artery), and fluoroscopic and echocardiographic guidance (often transesophageal or transthoracic) is used to cross the ductus, size the defect with angiography, and deploy an occlusion device. Hemodynamic measurements, oxygen saturations, and angiographic runs are performed before device selection. Post-deployment angiography and echocardiography confirm device position and absence of residual shunt or obstruction to adjacent structures. The patient is monitored in a post-anesthesia care unit or pediatric cardiac observation unit for complications such as vascular injury, device embolization, arrhythmia, or hemolysis before discharge or admission for observation. The procedural workflow typically involves the interventional pediatric cardiologist, pediatric cardiac anesthesiologist, catheterization lab nursing and technologist staff, and echocardiography support for intra-procedural imaging.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when billing only the physician’s professional interpretation or supervision portion of a service if separated from technical component.
`50`	Bilateral procedure	Use when procedure is reported for bilateral structures (rare for PDA closure; generally not applicable but listed for completeness if bilateral lesions documented).
`51`	Multiple procedures	Use when multiple distinct procedures are performed in the same session in addition to PDA closure.
`52`	Reduced services	Use when the procedure is partially reduced or not completed as originally planned.
`53`	Discontinued procedure	Use when the procedure is started but terminated due to unforeseen circumstances before completion.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons during the procedure.
`78`	Return to operating room for related procedure during global period	Use when a return-to-OR procedure related to the original surgery occurs during the global period.
`80`	Assistant surgeon	Use when an assistant surgeon performs part of the procedure.
`81`	Minimum assistant surgeon	Use when a minimum assistant is documented and appropriate.
`82`	Assistant surgeon (when qualified resident not available)	Use when an assistant surgeon is required and no qualified resident is available.
`73`	Discontinued outpatient hospital/ambulatory surgery before anesthesia	Use when the outpatient procedure is cancelled after preparation but before administration of anesthesia.
`22`	Increased procedural services	Use when work required to perform the service is substantially greater than typically required.
`26`	Professional component	(listed above; applicable when imaging or interpretation is billed separately)
`CQ`	Service furnished by a CRNA under direction of a physician	Use when a CRNA furnishes anesthesia services and reporting of provider type is needed.
`QX`	CRNA service performed with medical direction by a physician	Use when a CRNA provides services with physician medical direction.
