Summary & Overview
CPT 73202: CT Upper Extremity, Without and With Contrast
CPT code 73202 denotes CT imaging of the upper extremity performed in two phases: an initial non-contrast acquisition followed by a contrast-enhanced acquisition. This dual-phase study provides comprehensive anatomic and vascular detail useful for assessing trauma, infection, inflammatory disorders, neoplasm, and vascular compromise in the shoulder, arm, elbow, forearm, wrist, or hand. Nationally, accurate coding for combined non-contrast and contrast CT studies affects utilization tracking, payment adjudication, and clinical decision support for advanced imaging.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical purpose and typical sites of service for the procedure, common modifier usage where available, and an outline of areas that influence billing and claims processing. The publication summarizes benchmark considerations, payer coverage patterns, and operational notes relevant to imaging departments and billing teams. It also highlights clinical contexts in which dual-phase CT of the upper extremity is frequently ordered and the implications for documentation and imaging protocol selection. Data not available in the input are noted where applicable.
Billing Code Overview
CPT code 73202 describes a computed tomographic (CT) imaging procedure of the upper extremity performed twice: first without contrast and then repeated after intravenous contrast material is administered. This diagnostic CT imaging captures both non-contrast and contrast-enhanced phases to evaluate bones, joints, soft tissues, and vascular structures of the upper limb.
Service type: Diagnostic imaging — CT of the upper extremity, with and without contrast
Typical site of service: Outpatient radiology department, hospital imaging center, or ambulatory imaging facility
Clinical & Coding Specifications
Clinical Context
A 54-year-old right-handed patient presents to the outpatient imaging center with persistent wrist pain and intermittent paresthesias following a fall six weeks earlier. The referring orthopedic surgeon requests advanced imaging to evaluate for occult fracture, intra-articular joint pathology, and suspected vascular or soft-tissue abnormality. The patient is screened for contrast allergy and renal function; peripheral IV access is established for contrast administration. The CT technologist performs a noncontrast axial CT of the affected upper extremity (wrist and distal forearm), followed by intravenous iodinated contrast injection and timed post-contrast imaging of the same region to assess enhancement patterns of soft tissues, vascular structures, and potential infection or tumor. The interpreting radiologist reviews both noncontrast and contrast-enhanced series, documents comparison with prior radiographs, and provides a structured report with findings and impressions for the referring provider. Typical sites of service are hospital outpatient imaging departments, freestanding radiology centers, or ambulatory surgery centers equipped for CT with contrast capabilities. The anticipated workflow includes patient registration, consent for contrast, pre-scan screening, image acquisition (noncontrast then contrast-enhanced), image reconstruction, radiologist interpretation, and electronic report delivery to the referring clinician.
