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.
