C50.11 identifies a malignant tumor in the central portion of the female breast, typically involving the nipple and areolar region. Use it when documentation specifies this exact breast location.
Clinical signs
Clinical features may include a breast mass, nipple changes, skin dimpling, or nipple discharge. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a primary breast malignancy centered in the central portion of the female breast. It is appropriate for pathology-confirmed cancer, imaging-supported diagnosis, or a documented clinical diagnosis when the site is clearly stated. If laterality or site is unclear, check documentation.
Do not use for
Do not use it for benign breast disease, unspecified breast cancer sites, or male breast malignancy. Check documentation if the record does not clearly identify the central portion of the female breast.
Coding tip
