What 74175 covers
This study uses CT and contrast to show abdominal blood vessels and surrounding anatomy. It is commonly ordered to assess concerns such as an abdominal aortic aneurysm, arterial narrowing, or suspected vascular injury. A radiology technologist performs the scan in a hospital or imaging center; a radiologist interprets the images. The study may include noncontrast images and image processing as part of the CTA protocol.
Select this code when the examination is a CTA of the abdomen, rather than a routine contrast-enhanced abdominal CT or a CTA that also covers the pelvis. Documentation should identify the clinical indication, abdominal territory examined, CTA protocol, and interpretive findings. The global service is billed without a component modifier; modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service. Medicare's diagnostic imaging multiple procedure reduction applies to both the technical and professional components when applicable.

74175 billing questions
How is this different from a routine abdominal CT with contrast?
Use 74175 for a CT angiographic examination focused on abdominal vessels. A routine contrast-enhanced abdominal CT, without a CTA vascular protocol, is generally reported with 74160.
When should the pelvis be included in the CTA code?
When the CTA examination covers both the abdomen and pelvis, consider 74174 rather than 74175. The documented scan territory should support the code selected.
What do modifiers 26 and TC represent?
Modifier 26 reports the physician's interpretation, and modifier TC reports the technical service, including equipment and staff. Billing without either modifier represents the global service.
Can the noncontrast images be billed as a separate abdominal CT?
Noncontrast images may be part of the CTA protocol for 74175. Do not treat that phase alone as a separate CT service without documentation supporting a distinct examination.
What documentation supports reporting 74175?
The record should establish the vascular indication, that the abdomen was examined using a CTA protocol with contrast, and the interpreting physician's findings.
How does the imaging multiple procedure reduction affect this code?
When the reduction applies, Medicare's diagnostic imaging multiple procedure reduction affects both the technical and professional components of 74175.
