Summary & Overview
HCPCS G0206: Diagnostic Mammography, Unilateral with CAD
HCPCS Level II code G0206 represents a unilateral diagnostic mammography exam, including computer-aided detection (CAD) when performed. Diagnostic mammography is used to evaluate a specific breast complaint or imaging abnormality and remains a core component of breast imaging services nationwide. Accurate coding for diagnostic mammography affects clinical documentation, access to appropriate imaging, and payer processing across both commercial and public plans.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for unilateral diagnostic mammography, typical sites of service, and common billing elements associated with the procedure. The publication summarizes national benchmarks where available, highlights recent policy or coverage updates relevant to diagnostic breast imaging, and outlines coding nuances that influence reimbursement pathways.
This summary is intended for billing managers, radiology administrators, and policymakers seeking a concise reference on G0206 to inform operations, billing accuracy, and payer communications. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 55-year-old woman presents to an outpatient radiology center for a diagnostic mammography of the right breast following an abnormal screening mammogram that identified a suspicious focal asymmetry. The visit is scheduled as a targeted diagnostic study to evaluate a palpable lump and correlate prior imaging. Clinical workflow: the patient registers at the front desk, clinical indication and prior images are reviewed, and informed consent for imaging is confirmed. A mammography technologist acquires targeted views of the affected breast using digital equipment; computer-aided detection (CAD) is applied if available. Images are transmitted to a radiologist who performs interpretation (professional component) and documents findings in the report. The radiology group bills the technical component (TC) for facility/equipment and supplies and the interpreting physician bills the professional component (26) when billed separately. If additional procedures are required (ultrasound, biopsy), those are scheduled and billed separately under their respective codes.
