What 93580 covers

This service closes an atrial septal defect or another congenital communication between the atria by delivering an occlusion device through a catheter. It is commonly performed for a suitably selected secundum ASD by an interventional cardiologist or congenital heart specialist in a cardiac catheterization laboratory, with imaging used to guide device placement and assess the result.

Report the code for the transcatheter closure service, supported by documentation of the defect or communication, its clinical indication and anatomy, device deployment, and the completion assessment. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Use 93580 for closure of a communication between the atria; use 93581 for a ventricular septal defect.
93582PDA closure
93582 treats a patent ductus arteriosus, not an opening between the atria.
93583Septal reduction
93583 is for transcatheter septal reduction, not device closure of an ASD or other interatrial communication.

93580 billing questions

How is this code distinguished from 93581?

93580 is for catheter-based closure of an interatrial communication, such as an ASD. 93581 describes closure of a ventricular septal defect.

Is this code reported for each closure device?

The code represents the transcatheter closure service, not a separate line for each device. Document the defect treated and the device deployment; do not infer units from the number of devices.

Can modifier 50 be used?

No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate for the anatomy and service.

How does the multiple procedure rule affect same-session services?

When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
