What 74174 covers

This study uses CT acquisition timed to intravenous contrast to show abdominal and pelvic arteries in cross-sectional detail. Image data may be reconstructed into vascular views to assess aneurysm, dissection, narrowing, blockage, or anatomy before or after vascular treatment. Radiologists interpret the examination, commonly ordered by vascular surgeons, emergency clinicians, and other treating physicians when a vascular question involves both regions. Settings include hospital imaging departments and freestanding imaging centers.

Choose 74174 when the CTA examination includes both abdomen and pelvis; 74175 is the abdomen-only counterpart. The order and report should support the vascular indication and anatomic coverage, contrast-enhanced acquisition, and interpretation. Bill the complete service when one entity furnishes acquisition and interpretation; use modifier 26 for the professional interpretation or TC for technical performance when those components are billed separately. CMS diagnostic imaging multiple-procedure reduction applies to both technical and professional components when it applies to multiple procedures.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

74175Cta abdomen w/contrast
74175 is the CTA abdomen-only code. Choose 74174 when the CTA examination also covers the pelvis.
74177CT abdomen and pelvis
74177 represents conventional contrast CT of the abdomen and pelvis, rather than a CT angiography examination focused on vessels.
74178CT abdomen/pelvis
74178 is for conventional abdomen and pelvis CT performed without and with contrast; 74174 is the CTA service.
74185Mra abd w or w/o cntrst
74185 is abdominal MR angiography, not CT angiography. The modality and anatomy documented in the imaging service distinguish the codes.

74174 billing questions

When should 74174 be used instead of 74175?

Use 74174 when the CTA covers both the abdomen and pelvis. Use 74175 when the vascular imaging is limited to the abdomen.

Does 74174 include image acquisition and interpretation?

The global service includes both. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical component when billed separately.

Can 74175 also be reported for the abdominal portion?

Do not report 74175 separately to represent the abdominal portion of the same CTA that covers both abdomen and pelvis.

How does the multiple-procedure reduction affect this code?

When the diagnostic imaging multiple-procedure reduction applies, CMS applies it to both the technical and professional components.

What documentation supports reporting 74174?

The record should establish the vascular indication, that the CTA covered both abdominal and pelvic regions, use of contrast, and the interpreting physician's 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.
