2026 ICD-10-CM Diagnosis Code C50.111 – Malignant neoplasm of central portion of right female breast
What it is
C50.111 identifies a malignant tumor located in the central portion of the right breast in a female patient. Use it when documentation specifies the central breast region and the right side.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may describe a palpable breast mass, imaging abnormality, nipple changes, or biopsy-confirmed malignancy involving the central breast.
When to use this code
Use this code when the provider documents primary cancer of the central portion of the right female breast. It also fits pathology or imaging reports that clearly localize the malignancy to that breast region. If laterality or site is unclear, check documentation before coding.
Do not use for
Do not use it for left breast disease, unspecified breast site, or benign breast lesions. Also avoid it when the record does not confirm a malignant neoplasm.
Coding tip
Confirm both laterality and exact breast subsite in the pathology or operative note before assigning C50.111.
