ICD-10 Code C50.02 – Malignant neoplasm of nipple and areola, male (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C50.02 – Malignant neoplasm of nipple and areola, male
What it is
C50.02 identifies a malignant tumor arising in the nipple and areola of the male breast. Use it when the documentation specifies cancer in that exact anatomic site.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe a palpable nipple or areolar mass, nipple changes, ulceration, discharge, or other findings consistent with breast malignancy.
When to use this code
Use this code when the provider documents primary malignant neoplasm of the nipple and areola in a male patient. It also fits pathology or imaging-confirmed cancer at that site when the anatomic location is clearly stated. Check documentation if the record only says male breast cancer without a precise location.
Do not use for
Do not use it for benign breast lesions, inflammatory conditions, or unspecified male breast cancer. If the cancer site is elsewhere in the breast or not documented, choose the more accurate code or check documentation.
Coding tip
Verify both laterality and exact breast subsite in the record before assigning C50.02.
