CPT code 70552 represents a contrast-enhanced magnetic resonance imaging (MRI) study of the brain and brain stem. This diagnostic imaging code is frequently used in evaluating neurological symptoms, suspected intracranial lesions, inflammatory and infectious conditions, and when enhanced visualization of vascular and soft-tissue detail is required. Nationally, contrast MRI exams are key components of neuroimaging pathways and influence utilization, outpatient imaging capacity, and payer coverage policy.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical indications and typical sites of service, common modifiers and billing considerations, and a summary of payer coverage patterns where available. The publication also highlights benchmarks and utilization context relevant to radiology and neurology service lines.

This report provides clinicians, billing staff, and policy analysts with concise reference material on coding practice for contrast-enhanced brain MRI, expected service settings, and the payer landscape. Data not available in the input is noted where applicable. The goal is to clarify the code's clinical purpose and the administrative considerations that commonly accompany billing for this MRI study.
