CPT code 70543 represents an MRI examination of the orbits, face, and/or neck performed with multi-sequence, multi-planar imaging first without contrast and then with contrast. This combined non-contrast and contrast study enables detailed evaluation of soft-tissue structures and is commonly used to detect and characterize tumors, inflammatory or infectious processes, vascular abnormalities, and other pathologies affecting the orbits and adjacent facial and neck tissues. Nationally, this code is clinically significant because it guides imaging strategy for complex head and neck presentations and influences resource use in radiology departments.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise benchmarks and clinical context related to utilization of MRI with and without contrast for orbital and head/neck indications, common billing considerations, and policy-relevant updates affecting coverage and coding practice. The publication summarizes typical sites of service, expected clinical scenarios for use of CPT code 70543, and common administrative concerns such as prior authorization and documentation standards.
