(Chief Complaint: Palpable lump in the left breast.

This is adiagnosticmammogram (not screening) performed onone breast (left). CPT distinguishes screening from diagnostic:77067is screening mammography and is not appropriate because there is a symptom (palpable lump) and the service is diagnostic. CPT also distinguishes unilateral vs bilateral diagnostic:77065isdiagnostic mammography, unilateral, and77066is diagnostic mammography, bilateral—so the correct selection is77065. The vignette mentions CAD, but current mammography CPT coding incorporates digital and CAD elements into the diagnostic mammography code structure in typical CPC-style testing, and the question asks which code(s) are reported, offering only single-code answers.77061is not the primary diagnostic mammography code; it relates to breast tomosynthesis add-on concepts in many coding frameworks, but the stem describes diagnostic mammography with additional views, not explicit tomosynthesis reporting. Therefore, for unilateral diagnostic mammography of the left breast, the correct code is77065.
