Head or Neck

70544, 70545, 70546, 70547, 70548, and 70549

An MRA of the head or neck is a benefit when indicated and used to visualize or rule out cerebrovascular disease, subarachnoid and intracerebral hemorrhage, and occlusion or stenosis of intracranial vessels.

Chest

71555

An MRA of the chest is a benefit when performed to evaluate coronary artery disease or anomalous arteriopulmonary systems and to identify thoracic aneurysms or pulmonary embolisms in cases when contrast material is contraindicated. MRAs are also benefits for evaluating the coronary vessels in coronary artery disease, vasculitis, or vessel patency postoperatively.

An MRA of the chest is a benefit when used to diagnose a pulmonary embolism only when the client has a documented allergy to iodinated contrast material.

Abdomen

74185

An MRA of the abdomen is a benefit when used to assess the main renal arteries for the evaluation of renal artery stenosis, abdominal aortic aneurysm or dissection, and associated occlusive disease.

Pelvis

72198

An MRA of the pelvis is a benefit when performed to evaluate pelvic arteries for stenosis and for the detection, grading, and differentiation of renovascular disease.

Lower Extremities

73725

An MRA of the lower extremities is a benefit when indicated for the evaluation of peripheral vascular disease related to the lower extremities, such as hemangioma, atherosclerosis, arterial embolism and thrombosis, and arterial anomalies.

If an MRA and a conventional angiography are performed on the same day, the documentation of medical necessity must indicate that a conventional angiography did not identify a viable run off vessel for bypass, or that MRA results were inconclusive, or other medical necessity documentation.
