What 77061 covers
This service uses mammographic X-ray images taken from multiple angles to create layered views of one breast for diagnostic evaluation. Breast imaging centers and radiology practices use it when assessing a symptom, such as a palpable finding, or further evaluating an abnormal screening result. It is the unilateral diagnostic code; bilateral diagnostic tomosynthesis and bilateral screening tomosynthesis have separate codes.
Medicare assigns CPT 77061 status I: it is not valid for Medicare reporting, and Medicare uses HCPCS G0279 to report and pay for diagnostic breast tomosynthesis. The CPT code denotes unilateral imaging, not a count of views or reconstructed slices. When conventional diagnostic mammography is also performed, the mammography service has its own code; unilateral diagnostic mammography is represented by 77065.
