CPT 77047: Bilateral Breast MRI, Non-Contrast

CPT code 77047 represents a bilateral, non-contrast breast magnetic resonance imaging (MRI) exam that produces three-dimensional images using magnetic fields and radiofrequency waves. This diagnostic imaging code is nationally relevant for breast cancer screening, diagnostic workups, and surveillance when contrast is not administered or is contraindicated. Breast MRI is an important tool in high-risk screening, problem-solving imaging, and preoperative planning, and proper coding affects clinical documentation, payer coverage determinations, and facility planning.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication summarizes how 77047 is used across settings, typical billing considerations, and where policy updates could affect coverage and coding practice.

Readers will learn the clinical context for use of CPT code 77047, the typical sites where the service is delivered, and the implications for billing and reimbursement workflows. The report includes benchmarking and payment context, common modifiers and billing considerations (where provided), and notes on documentation elements that support the use of a non-contrast bilateral breast MRI. Data not available in the input is identified where applicable.

Clinical & Coding Specifications

Clinical Context

A 48-year-old woman with dense breast tissue and a prior history of suspicious findings on screening mammography is referred for a diagnostic breast MRI without contrast to further evaluate complex parenchymal asymmetries and to localize architectural distortion identified on prior imaging. The patient arrives at an outpatient radiology center and is registered, screened for MRI contraindications (eg, pacemaker, metallic implants, pregnancy, renal failure is not relevant for non-contrast), and provided ear protection. The MRI technologist positions the patient prone with the breasts placed in a dedicated bilateral breast coil. The protocol includes multiplanar, high-resolution, non-contrast sequences such as T1-weighted, T2-weighted, STIR/fat-suppressed, and diffusion-weighted imaging to characterize lesions. The interpreting radiologist reviews images, documents BI-RADS assessment, and provides an impression indicating whether further evaluation with contrast-enhanced MRI, ultrasound, or biopsy is recommended. Image post-processing generates three-dimensional reconstructions. Final images and report are transmitted to the referring clinician for management decisions.
