What 93563 covers

During congenital heart catheterization, the physician selectively engages the coronary arteries, injects contrast, and obtains angiographic images for interpretation. A congenital or interventional cardiologist typically performs this work in a cardiac catheterization laboratory. The images may help define coronary anatomy, such as the origin and course of the arteries, in a patient with congenital heart disease.

Report 93563 as an add-on with the primary congenital heart catheterization procedure, not as a stand-alone service. Documentation should identify the congenital catheterization, the selectively imaged coronary arteries, the injection and imaging performed, and the physician’s interpretation. Distinguish native coronary angiography from angiography of bypass grafts, which is described by a different add-on code. Under the CMS rule, payment for 93563 falls within the primary procedure’s global period.

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.

93563 billing questions

Can 93563 be billed by itself?

No. It is an add-on code and must be reported with a primary congenital heart catheterization procedure.

How does 93563 differ from 93564?

93563 describes selective imaging of the coronary arteries during congenital catheterization. 93564 describes selective opacification of aortocoronary bypass grafts.

Does 93563 describe left- or right-heart chamber angiography?

No. It concerns coronary angiography. Selective left- or right-heart chamber angiography is described by 93565 or 93566, respectively.

What documentation supports reporting 93563?

Document the primary congenital catheterization, selective coronary engagement and contrast imaging, the arteries imaged, and the interpretation of the angiographic findings.

How does CMS treat the payment period for 93563?

CMS treats 93563 as an add-on paid within the global period of the primary procedure.

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.
