This CPT code 73701 represents the performance of a computed tomography (CT) scan of a patient's lower extremity utilizing contrast material.The procedure involves the acquisition and interpretation of cross-sectional images to aid in the diagnosis of fractures or other lower extremity diseases.The code encompasses both the technical and professional components of the service, including patient positioning, contrast administration (intravenously via an upper extremity vein), image acquisition and analysis, and the generation of a diagnostic report.

Example 1: A patient presents to the emergency department following a motor vehicle accident with suspected lower extremity fractures. A CT scan with contrast is ordered to assess the extent of the injuries., A patient with a history of deep vein thrombosis (DVT) in the lower extremity experiences worsening pain and swelling. A CT scan with contrast is performed to evaluate for the presence of thrombus and its location., A patient is referred for a lower extremity CT scan with contrast due to suspected soft tissue infection that involves bone.The study aids in determining the extent and nature of the infection.

* Physician's order specifying the need for a CT scan of the lower extremity with contrast.*Relevant clinical history and physical examination findings.*Imaging report clearly documenting findings of the CT scan, including specific location, measurements and nature of any abnormalities.*Documentation supporting medical necessity for the procedure.
