What 70544 covers
This study uses magnetic resonance techniques to create angiographic images of blood vessels within the head without contrast material. It is commonly ordered to assess suspected intracranial aneurysm, vessel narrowing, or other vascular abnormalities. A technologist performs the scan in an imaging department or hospital, and a radiologist interprets the images and reports the findings. The study evaluates the intracranial vessels, rather than brain tissue as the primary target.
Report 70544 when the head angiographic examination is performed without contrast; use the applicable contrast-specific code when contrast is administered. Documentation should identify the head vessels examined, the imaging technique, contrast status, and the interpreting physician’s findings. The global service includes both the technical work of image acquisition and the professional interpretation. Modifier 26 identifies the interpretation, while modifier TC identifies the technical service. When multiple diagnostic imaging procedures are performed, the CMS multiple procedure reduction applies to both the technical and professional components.

- 70546Head MR angiographyWithout and with contrast
- Choose 70546 when the head MRA includes imaging both without and with contrast. 70544 describes the study without contrast only.
- 70547Neck MRAWithout contrast
- 70547 examines neck vessels without contrast. Use 70544 for angiographic imaging of vessels within the head.

70544 billing questions
How does 70544 differ from 70545?
70544 describes head MRA performed without contrast. Use 70545 when contrast is used for the head angiographic study.
When is 70546 used instead?
70546 is for head MRA performed both without and with contrast. It is not the code for a study performed only without contrast.
Can a brain MRI be reported with 70544?
A separately performed MRI of the brain may be reported when it is a distinct study, such as a brain MRI without contrast reported with 70551. The documentation should support both examinations.
How should the professional and technical services be billed?
Report 70544 without a component modifier for the global service. Use modifier 26 for the professional interpretation or modifier TC for the technical service when those portions are billed separately.
Does the multiple imaging reduction affect 70544?
Yes. When multiple diagnostic imaging procedures are performed, the CMS multiple procedure reduction applies to both the technical and professional components.
