CPT code 73223 denotes an MRI study of one or more joints of the upper extremity performed both without and with intravenous contrast. This two-phase MRI protocol is used to evaluate shoulder, elbow, wrist, and hand joint pathology where contrast-enhanced imaging can clarify soft-tissue, synovial, or vascular findings. Nationally, this code matters because MRI utilization, appropriate use, and correct coding affect imaging quality, care pathways, and payer reimbursement across outpatient settings.

Key payers commonly involved in coverage and payment considerations include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for contrast and noncontrast joint MRI, typical sites of service where the procedure is delivered, and the common modifiers associated with imaging service lines. The publication summarizes what to expect in payer coverage patterns and documentation requirements, highlights national coding nomenclature, and identifies where input is unavailable.

This summary is intended for a national audience of coding professionals, radiology administrators, and policy analysts seeking a clear, practical reference for CPT code 73223 and its role in upper-extremity MRI diagnostic workflows.
