ICD-10 Code C50.92 – Malignant neoplasm of breast of unspecified site, male (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C50.92 – Malignant neoplasm of breast of unspecified site, male
What it is
C50.92 identifies a malignant breast tumor in a male when the site within the breast is not specified. Use it when documentation confirms breast cancer but does not name a more exact quadrant or location.
Clinical signs
Clinical features may include a palpable breast mass, nipple changes, or breast enlargement. Clinical features vary; refer to documentation, pathology, and imaging for the confirmed diagnosis.
When to use this code
Use this code when the provider documents primary malignant neoplasm of the breast in a male and does not specify the breast site. It also fits when the record supports breast cancer but laterality or exact location is not documented. Check documentation if the tumor site is later clarified.
Do not use for
Do not use it for benign breast lesions, gynecomastia, or unspecified breast symptoms without a cancer diagnosis. Avoid it if a more specific breast site code is documented.
Coding tip
Verify that the record states malignancy and male breast before assigning C50.92.
