Medicare pays $282.66–$314.06 for 75705 in the office in Illinois, from Rest Of Illinois to Chicago. Which amount applies depends on the service address.
Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 75705 covers
This service covers selective contrast imaging of spinal arteries, with radiological supervision and interpretation. It is commonly performed in a hospital or other imaging facility by an interventional radiologist or neuroradiologist when a spinal vascular lesion, such as an arteriovenous malformation or fistula, needs angiographic evaluation. The study may involve imaging multiple spinal arterial feeders to define the lesion’s blood supply.
Report the code for the spinal arterial imaging and interpretation, supported by the angiographic images and a report identifying the vessels studied and findings. Catheter placement is described separately when supported by the procedure performed; the applicable placement code depends on the catheter’s position. Bill globally when one entity provides both the professional interpretation and technical service, or use modifier 26 for the professional component and TC for the technical component. When multiple cardiovascular diagnostic procedures are performed, the multiple procedure reduction applies to the technical component.

How to choose
- 75710Extremity angiography
- 75710 describes unilateral arm or leg arterial imaging. Use 75705 when the selectively studied arteries supply the spine.
- 75726Visceral angiography
- 75726 is for abdominal arterial imaging; 75705 is for selective spinal artery imaging, even when access involves vessels arising from the aorta.
- 75774Arterial imaging
- 75774 describes additional selective vessel imaging beyond a basic examination. It is an add-on, not the primary code for the spinal angiographic study.
75705 billing questions
When should this code be chosen instead of an extremity angiography code?
Use 75705 for selective imaging of spinal arteries. Codes such as 75710 describe angiography of an arm or leg, not the spinal arterial supply.
Can catheter placement be reported separately?
A catheter placement service may be separately reported when supported by the procedure. Select the placement code according to the catheter’s arterial position and order.
How should the professional and technical work be billed?
Report the global service without a component modifier when one entity provides both parts. Use modifier 26 for the interpretation or TC for the technical service when billed separately.
Does the multiple procedure reduction affect both components?
The cardiovascular diagnostic multiple procedure reduction applies to the technical component.
What documentation supports reporting spinal angiography?
Retain the angiographic images and a report identifying the spinal arteries selectively studied and the interpretation of the findings.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
