Malignant neoplasm of nipple and areola, unsp female breast

This code signifies a cancerous tumor originating in the nipple or areola region of an unspecified female breast. It indicates the presence of a primary malignancy in this specific anatomical area without further detail regarding laterality.

This code is appropriate when documentation confirms a malignant neoplasm of the nipple and areola in a female patient, and the medical record does not specify whether it is the right or left breast. It is used when the physician's diagnosis explicitly states "unspecified breast" or when laterality cannot be determined from the available clinical notes.

• Ensure the documentation clearly states "nipple and areola" as the tumor site.
• Avoid using this code if laterality (right or left breast) is documented; instead, select the more specific code.
• This code should be sequenced as the primary diagnosis when it is the reason for the encounter.
