This policy applies to all physicians, other health care professionals, inpatient hospitals, outpatient hospitals and ASCs.


Spinal Angiography
Placement of a catheter via the femoral artery into paired spinal arteries (intercostal above and lumbar below the diaphragm) with injection of contrast and imaging of the blood flow to the spine or spinal cord. This may also include injection of supreme intercostal, subclavian, thyrocervical, vertebral, internal iliac and median sacral arteries.

Vascular Family
A group of vessels or arteries that are fed by a primary branch of the aorta or a primary branch of vessel punctured. A vascular family is divided into a primary branch, secondary branches and tertiary branches. Each primary branch with its secondary and tertiary branches would be a single vascular family. The primary branch would be the first order; the secondary branch would be the second order and the tertiary branch and beyond would be the third order.

Selective Catheterization
The movement, manipulation or guidance of the catheter into a part of the arterial system beyond the aorta or the original vessel punctured.

Supervision and Interpretation (S/I)
The personal supervision of the performance of the radiologic portion of a procedure and the interpretation of the findings.

Policy statement

Our health plan considers arterial branches off the aorta as one vascular family. Per Medicare Benefit Policy Manual, diagnostic tests including spinal angiography are eligible for reimbursement when all the following are met:

  • When supported by a referring physician's signed written order in the patient's medical record.
  • When the attending or supervising physician is present during the procedure.
  • When there is a documented signed procedure report by the supervising/attending physician in the patient's medical record.

Spinal angiography is not eligible for reimbursement when performed by an Interventional Radiology fellow without the presence of an attending physician.

Spinal angiography may be performed in the outpatient or inpatient hospital setting.
