What 75756 covers
This service covers angiographic images and their interpretation for an internal mammary artery, a chest artery often used as a coronary bypass graft. It is commonly performed in a catheterization laboratory or interventional radiology setting when a physician selectively evaluates a mammary artery, such as to assess a graft in a patient with prior coronary bypass surgery. The interpreting physician reviews the contrast images and documents the findings for the artery examined.
Report the service for the internal mammary artery actually evaluated, with documentation identifying the vessel and supporting the medical reason for imaging. CMS recognizes professional and technical components: report modifier 26 for the physician’s interpretation, modifier TC for equipment and staff, or no component modifier for the global service. When multiple cardiovascular diagnostic procedures are performed, the multiple-procedure reduction applies to the technical component.

- 75726Visceral angiography
- 75726 is for abdominal visceral arterial imaging, not an internal mammary artery.
- 75774Arterial imaging
- 75774 describes selective imaging of an additional vessel after a basic examination; 75756 identifies internal mammary artery imaging.
75756 billing questions
When is this code more appropriate than an extremity angiography code?
Use this code for angiographic evaluation of an internal mammary artery. Codes such as 75710 and 75716 describe imaging of limb arteries instead.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service; billing without either modifier represents the global service.
What documentation supports reporting this service?
The record should identify the internal mammary artery examined, the clinical reason for imaging, and the physician’s interpretation of the angiographic findings.
Does the cardiovascular multiple-procedure reduction affect both components?
CMS applies the reduction to the technical component when multiple cardiovascular diagnostic procedures are performed.
How is this code distinguished from 75774?
This code identifies angiography of an internal mammary artery. Code 75774 describes selective imaging of an additional vessel after a basic examination.
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.
