ICD-10 Code C50.119 – Malignant neoplasm of central portion of unspecified female breast (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C50.119 – Malignant neoplasm of central portion of unspecified female breast
What it is
This code identifies a malignant tumor in the central portion of a female breast when the side is not documented. Use it for a breast cancer diagnosis centered near the nipple or areola area.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include a palpable breast mass, nipple changes, skin retraction, or abnormal imaging that supports malignancy in the central breast.
When to use this code
Use this code when the record clearly states malignant neoplasm of the central portion of the female breast and does not specify left or right side. It is appropriate for confirmed breast cancer documented by the clinician, pathology, or oncology note. If the site is described differently, code the more specific breast location instead.
Do not use for
Do not use this code for benign breast disease, unspecified breast mass, or lesions in a different breast quadrant. Check documentation if the laterality or exact site is missing.
Coding tip
Always confirm both the central location and the unspecified laterality before assigning C50.119.
