What 75774 covers
This add-on covers angiographic imaging of a separately selected artery beyond the initial examination. A physician, commonly an interventional radiologist or another specialist performing an angiographic procedure, evaluates the additional vessel using selective contrast injection and imaging, then interprets the findings. It may be useful when the initial study identifies a need to assess another artery for a stenosis, aneurysm, bleeding source, or other vascular finding.
Report one unit for each additional vessel actually studied, alongside the primary angiography code; it cannot be billed by itself. The procedure report should identify the additional vessel, describe the selective injection and images, and document the interpretation. This add-on is paid within the primary procedure’s global period. Modifier 26 identifies the interpretation, modifier TC identifies the equipment-and-staff portion, and billing without either modifier represents the global service.

How to choose
- 75710Extremity angiography
- Use 75710 for the initial unilateral extremity angiographic examination. 75774 represents an additional selectively studied vessel after a primary examination.
- 75716Extremity angiography
- Use 75716 for the initial bilateral extremity angiographic examination. Report 75774 only for additional vessel imaging beyond that examination.
- 75726Visceral angiography
- Use 75726 for the primary abdominal visceral angiographic examination. 75774 is for a separately studied additional vessel, not another primary abdominal study.
75774 billing questions
Can 75774 be billed by itself?
No. It is an add-on and must be reported with a primary angiography procedure. The record should support imaging of an additional, separately selected vessel.
What supports reporting an additional unit?
Document each additional vessel studied, including its selective injection, images, and interpreted findings. Extra views of the same vessel alone do not establish another vessel.
How does 75774 differ from 75710 or 75716?
Those codes describe the initial unilateral or bilateral extremity angiographic examination. Use 75774 for an additional selectively studied vessel beyond the primary examination, not to represent the initial study.
When should modifier 26 or TC be used?
Use modifier 26 for the physician’s interpretation or TC for the technical service involving equipment and staff. Without either modifier, the claim represents the global service.
Does 75774 require a primary angiography code on the claim?
Yes. Submit it with the primary angiography procedure that provides the initial examination; payment is within that procedure’s global period.
