This billing/coding guideline complements LCD L33459 (Computerized Axial Tomography (CT), Thorax); follow the LCD for clinical coverage and any required documentation or prior authorization rules.
All documentation must be maintained in the patient's medical record and made available to the contractor upon request.
Every page of the record must be legible and include appropriate patient identification information such as complete name and dates of service.
The documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care.

Diagnostic abdominal aortography and renal angiography are covered when they meet the reasonable and necessary clinical requirements specified in LCD L35092.
When femoral or iliac angiography is performed at the time of coronary angiography, bill using HCPCS code G0278.
MRA is covered to evaluate blood flow in the internal carotid vessels of the head and neck.
MRA of peripheral arteries of the lower extremities is covered to determine the presence and extent of peripheral vascular disease and may substitute for conventional angiography (CA).
MRA is covered for pre-operative evaluation of patients undergoing elective abdominal aortic aneurysm (AAA) repair when it is comparable to CA for determining extent of AAA and evaluating aortoiliac occlusive disease and renal artery pathology necessary for surgical planning.
MRA of the renal arteries and aortoiliac arteries (in the absence of AAA or aortic dissection) is covered when MRA is expected to avoid CA, physician history/physical and standard assessments are insufficient, and obtaining MRA has a high probability of positively affecting patient management.
