CT imaging
About 73702: Lower extremity CT without and with contrast
Reports CT imaging of a lower extremity when the examination includes both unenhanced images and subsequent contrast-enhanced images in the same study.
This service covers CT imaging of a lower extremity, such as the foot, ankle, knee, or hip, performed first without contrast and then with contrast during the same examination. Radiologists interpret the images; technologists perform the scan in hospital imaging departments, outpatient imaging centers, and other CT-equipped settings. A combined protocol may be selected when the clinical question calls for both unenhanced and contrast-enhanced views, such as evaluating a suspected soft-tissue infection or mass.
Report this code for the combined examination rather than separately reporting the unenhanced and contrast-enhanced phases as individual CT studies. Documentation should identify the body region and support the need for both phases. The service has professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff portion, and billing without either modifier represents the global service. When multiple diagnostic imaging services are performed, CMS's multiple-procedure reduction applies to both components. When imaging is performed on both sides, each side is paid separately at 100%.

73702 billing questions
When should this code be chosen instead of 73700 or 73701?
Use this code when the same lower-extremity CT examination includes images without contrast followed by images with contrast. Use 73700 for an unenhanced-only study and 73701 for a contrast-only study.
Can the unenhanced and contrast phases be billed as separate CT codes?
No. This code represents the combined examination when both phases are performed as one study.
How are the professional and technical portions reported?
Use modifier 26 for the physician's interpretation and report, or modifier TC for the technical service. Without either modifier, the claim represents the global service.
How is bilateral lower-extremity imaging paid?
CMS pays each side separately at 100% when both sides are imaged. The documentation should identify the side or sides examined.
What documentation supports reporting this code?
Document the lower-extremity region examined and the clinical reason for obtaining both unenhanced and contrast-enhanced images. The record should support that both phases were performed in the same examination.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
