CPT 93580: Transcatheter Atrial Septal Defect Closure

CPT code 93580 represents a percutaneous transcatheter atrial septal defect (ASD) closure procedure in which an implant is delivered via catheter to seal an opening in the atrial septum. Nationally, this code captures an important, minimally invasive alternative to open surgical repair for congenital or iatrogenic atrial septal communications and is relevant for cardiac interventionalists, hospitals, and payers managing complex cardiovascular care.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and the common modifiers that may accompany claims. The publication also highlights benchmarking elements commonly reviewed by payers and providers (procedure utilization, site-of-service patterns, and coding nuances) and notes where input data is not provided.

This summary provides the groundwork to understand billing and administrative considerations tied to CPT code 93580, situating the code within cardiovascular service lines and hospital-based interventional care. Data not available in the input is flagged where relevant.

Billing Code Overview

CPT code 93580 describes a percutaneous transcatheter procedure to close an opening in the atrial septum (an atrial septal defect or surgically created opening). The provider advances a catheter through a large vein in the groin into the right side of the heart, injects contrast dye, obtains imaging of the atrial chambers and ventricles, and deploys an implant to occlude the septal defect.

Service type: Percutaneous transcatheter atrial septal defect closure
Typical site of service: Hospital catheterization laboratory or specialized cardiac interventional suite

Clinical & Coding Specifications

Clinical Context

A 7-year-old child with a history of exertional dyspnea and recurrent right-sided cardiac murmurs is referred for transcatheter closure of an atrial septal defect (ASD). Prior transthoracic echocardiography documents a secundum-type ASD with right atrial and right ventricular enlargement. The interventional cardiology team schedules a catheter-based procedure under general anesthesia in a cardiac catheterization laboratory. A femoral venous access is obtained, a catheter is advanced to the right atrium, and contrast angiography and transesophageal echocardiography (TEE) or intracardiac echocardiography (ICE) are used to define the defect size and rims. Hemodynamic measurements and imaging guide selection and deployment of a septal occluder device. Post-deployment angiography and echocardiography confirm device position and absence of residual shunt or obstruction. The patient is monitored in a post-anesthesia care area and typically discharged same day or after an overnight observation with instructions for activity restriction and endocarditis prophylaxis guidance as indicated.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when reporting only the physician interpretation/management component separate from technical services (rare for this code).
`52`	Reduced services	Use when the procedure is partially performed or curtailed for clinical reasons.
`53`	Discontinued procedure	Use when procedure is started but terminated due to patient instability or other emergent clinical issue.
`59`	Distinct procedural service	Use when an unrelated procedure or distinct service is performed on the same day and must be distinguished.
`62`	Two surgeons	Use when two surgeons with different specialties perform substantial, separate portions of the procedure.
`63`	Procedure performed on infants less than 4 kg	Use when patient weight meets that criterion and payer requires the modifier.
`76`	Repeat procedure by same physician	Use when the same physician repeats the procedure later the same day (not in provided list; omitted).
`78`	Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period	Use when a return to the cath lab is required for a complication or revision.
`79`	Unrelated procedure or service by the same physician during the postoperative period	Use when an unrelated procedure is performed during the global period.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist services in state with scope-of-practice requirement (Anesthesia modifier in some contexts)	Rarely used; include when applicable to anesthesia component reporting if required by payer.
`TC`	Technical component	Use when billing only the facility/technical component of imaging or monitoring associated with the procedure.
`QK`	Medical direction of two, three, or four concurrent anesthesia procedures involving qualified individuals	Use when the physician medically directs multiple concurrent anesthesia cases.
`XE`	Separate encounter, a service that is distinct because it occurred during a separate encounter	Use to indicate a distinct encounter separate from the primary procedure when allowed by payer.
