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.

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.
