2026 ICD-10-CM Diagnosis Code C50.112 – Malignant neoplasm of central portion of left female breast
What it is
This code identifies a malignant breast tumor located in the central portion of the left breast in a female patient. Use it when documentation specifies this exact site and laterality.
Clinical signs
Clinical features vary; refer to documentation. Breast cancer may present as a palpable mass, nipple changes, skin dimpling, or abnormal imaging findings, but the coded site must be clearly documented.
When to use this code
Use C50.112 when the provider documents primary malignancy in the central portion of the left female breast. It is appropriate for confirmed cancer diagnoses, including pathology or oncology notes that specify this location. If laterality or exact breast site is unclear, check documentation before coding.
Do not use for
Do not use this code for unspecified breast cancer, benign breast masses, or lesions in a different breast quadrant. If the record does not confirm the central left breast site, choose a more accurate code or verify the note.
Coding tip
Match the code to the exact breast site and laterality in the provider’s documentation before assigning C50.112.
