What 73706 covers
A CT technologist acquires noncontrast and postcontrast images of the lower-extremity arteries, with image processing to support vascular assessment. A radiologist or other qualified physician interprets the study. Common clinical situations include peripheral arterial disease, acute limb ischemia, and arterial injury, when clinicians need to define arterial anatomy for treatment planning. The examination focuses on vessels rather than routine assessment of bones, joints, or soft tissues and may be performed in a hospital imaging department or outpatient imaging center.
Select this code when the examination includes both noncontrast and postcontrast CT angiographic imaging of the lower extremity. Document the clinical indication, side examined, imaging performed, and interpretation. The global service includes the technical acquisition and professional interpretation; modifier 26 identifies the professional component, and modifier TC identifies the technical component. CMS applies the diagnostic imaging multiple procedure reduction to both components. When both sides are performed, CMS pays each side separately at 100%.

How to choose
- 73702CT scanWithout and with contrast
- 73702 is a routine lower-extremity CT with and without contrast, not an angiographic study. Choose 73706 when the examination is designed to depict arterial anatomy.
- 73725MR angiographyLower-extremity arteries
- 73725 reports lower-extremity MR angiography. Code 73706 reports the CT angiographic method.
- 75635CTA runoffAbdominal aorta and both legs
- 75635 covers CTA of the abdominal aorta with bilateral iliofemoral runoff. Use 73706 for lower-extremity CTA without that broader anatomic coverage.
73706 billing questions
How is this different from a routine CT of the lower extremity?
Code 73706 is for CT angiography depicting lower-extremity arteries. Code 73702 is a routine CT with and without contrast, not an angiographic study.
Can the professional interpretation and technical service be billed separately?
Yes. Use modifier 26 for the professional interpretation or modifier TC for the technical service; billing without either modifier represents the global service.
How should bilateral examinations be handled?
CMS pays each side separately at 100% when both sides are performed. Document the side examined and follow applicable claim-line instructions.
Does the multiple procedure reduction affect only the technical service?
No. CMS applies the diagnostic imaging multiple procedure reduction to both the technical and professional components.
What documentation supports reporting this code?
Document the vascular indication, the side examined, the noncontrast and postcontrast CT angiographic imaging performed, and the interpreting physician's findings.
