Coronary CT Angiography (CCTA) Medicare Information
Effective November 27, 2006

---

Medicare approved uses of Coronary CT Angiography (CCTA) include:

• Signs or symptoms of coronary artery disease (chest pain, angina, anginal equivalent, newly abnormal EKG). CCTA may precede stress testing or be used to clarify a non-diagnostic or equivocal stress test.

• Symptomatic or asymptomatic patients at high cardiovascular risk (e.g., left ventricular systolic dysfunction of unknown etiology, diabetes).

• Recurrent symptoms following stent placement or CABG to guide the decision for repeat invasive evaluation.

• Anatomic assessment of coronary artery grafts prior to repeat coronary surgery.

• Coronary artery assessment prior to non-coronary cardiovascular surgery.

• Anatomic evaluation before or after therapeutic electrophysiology procedures.

• Suspected aortic dissection or injury.

• Suspected congenital anomalies of the coronary circulation of the great vessels.

• Coronary artery evaluation following technically inadequate cardiac catheterization.

• Coronary artery anatomy following heart transplantation.
