Malignant neoplasm of unsp site of unspecified male breast

This code signifies a malignant tumor originating in the breast tissue of a male patient, where the specific location within the breast is not documented. It indicates an invasive carcinoma or other primary malignancy of the male breast without further anatomical specificity.

Use this code when the medical record confirms a primary malignant neoplasm of the male breast, but the physician documentation does not specify the quadrant, central portion, or axillary tail. This code is appropriate when the laterality (right or left) is also unspecified.

• Avoid using this code if the documentation specifies laterality (e.g., right or left breast); instead, use a more specific C50.91- code.
• Always query the provider for more specific anatomical site and laterality information if available in the medical record.
• This code represents an unspecified site and unspecified laterality; strive for greater specificity whenever possible to accurately reflect the patient's condition.
