CPT code 73706: CT angiography, lower extremity, without and with contrast2026 Medicare rate & RVUs

Medicare pays $321.65 for 73706 nationally in the office.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
