When it comes to coding aortic graft procedures, a couple of factors have to be considered to arrive at the correct CPT code.
1) What section of the aorta is the graft being placed in? The aorta is divided into the following sections:
– The abdominal aorta which begins at the level of the diaphragm (the muscle that separates your chest cavity from your abdomen) and continues to what is known as the iliac bifurcation where the abdominal aorta branches into the right and left common iliac arteries which supply blood flow to your legs.
– The descending thoracic aorta which begins at the lower end of the aortic arch (explained below) and proceeds down to the level of the diaphragm.
– The aortic arch which is located between the ascending aorta and the descending thoracic aorta and is the portion of the aorta that the “head vessels” (the subclavian, the carotid, and the brachiocephalic trunk arteries which supply blood flow to the head, neck, and arms) branch off of.
– The ascending aorta which begins at the upper end of the aortic arch and continues through the aortic root and down to the aortic valve. The aortic root is where the coronary arteries which supply blood flow to your heart connect to the aorta. The aorta ends at this point (the heart is located on the other side of the aortic valve).
