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%.

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.

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.
