C50.129 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of central portion of unspecified male breast. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

This code is applicable to male patients only. It is clinically and virtually impossible to use this code on a non-male patient.

Unspecified diagnosis codes like C50.129 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
