What 73701 covers
This service covers CT imaging of a lower extremity using contrast material to help evaluate structures such as bone and soft tissue. It may be used when the clinical question involves a suspected mass, infection, or other abnormality requiring contrast-enhanced cross-sectional imaging. A radiologic technologist performs the acquisition in a hospital or imaging center, and a radiologist typically interprets the images.
Select 73701 when the CT study is performed with contrast only; use 73702 when images are acquired both before and after contrast, and 73700 for a study without contrast. Documentation should identify the imaged extremity, clinical indication, contrast-enhanced technique, and interpretation. Modifier 26 identifies the professional interpretation, modifier TC identifies the technical service, and billing without either modifier represents the global service. For multiple diagnostic imaging services, CMS applies the multiple-procedure reduction to both components. When performed bilaterally, each side is paid separately at 100%.

How to choose
- 73700Extremity CT
- 73700 is for lower-extremity CT without contrast; 73701 is for a contrast-enhanced CT study.
- 73702CT scan
- 73702 applies when CT images are obtained both before and after contrast. Use 73701 when the study is performed with contrast only.
- 73706Ct angio lwr extr w/o&w/dye
- 73706 is for CT angiography of the lower extremity, a vascular imaging study. Use 73701 for a contrast-enhanced CT that is not a CTA examination.
- 73719Extremity MRI
- 73719 describes lower-extremity MRI with contrast. Choose between it and 73701 based on whether the performed modality is MRI or CT.
73701 billing questions
How is 73701 different from 73702?
Use 73701 when the CT is performed with contrast only. Use 73702 when the study includes images both before and after contrast.
When should 73700 be used instead?
73700 describes lower-extremity CT performed without contrast. The documented imaging protocol determines whether 73700 or 73701 is appropriate.
Which modifiers identify the components?
Modifier 26 identifies the radiologist's professional interpretation, while modifier TC identifies the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
How does CMS handle multiple imaging services?
The diagnostic imaging multiple-procedure reduction applies to both the professional and technical components of 73701 when multiple diagnostic imaging services are performed.
How is bilateral imaging paid?
CMS pays each side separately at 100% when the lower extremities are imaged bilaterally.
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.
