    Clinical & Coding Specifications

    Clinical Context

    A 52-year-old woman presents to an outpatient radiology center for routine breast cancer screening. The facility performs screening digital mammography and digital breast tomosynthesis (3D mammography). The technologist acquires screening images, which are interpreted by a board-certified radiologist. The radiologist documents the screening or diagnostic mammography results, including BI-RADS assessment, comparison to prior exams if available, and any recommended additional imaging or biopsy. The documented review of images is then recorded in the radiology report and routed to the referring provider and the patient portal. Typical site of service is an outpatient imaging center or hospital outpatient department. The service type is diagnostic and screening breast imaging interpretation and documentation of results for film, digital, or digital breast tomosynthesis (3D) mammography, corresponding to administrative and clinical review of mammography images and formal reporting.
