Malignant neoplasm of central portion of right female breast

This code signifies a cancerous tumor located in the central part of the right breast in a female patient. This area typically includes the nipple and areola, as well as the underlying breast tissue directly beneath them. It indicates a primary malignancy originating in this specific anatomical region.

Apply this code when documentation confirms a primary malignant neoplasm identified in the central portion of the right breast. This is appropriate for initial diagnoses, subsequent encounters for active treatment, or surveillance following treatment for this specific cancer. Supporting documentation includes pathology reports, operative reports, and physician notes detailing the tumor's location.

• Always confirm laterality (right vs. left) and the specific anatomical quadrant or central portion.
• Distinguish from overlapping lesion codes (C50.9-) if the tumor extends beyond the central portion into multiple quadrants.
• Ensure documentation specifies "female" if the patient's sex is not explicitly stated but implied by the breast cancer diagnosis.
