Neoplasm of uncertain behavior of female genital organ, unsp

This code signifies a tumor within the female reproductive system whose biological behavior (benign vs. malignant) cannot be definitively determined from pathology. It indicates that the pathologist has identified atypical cells but lacks sufficient information to classify the neoplasm as clearly benign or malignant.

Use this code when pathology reports describe a neoplasm of a female genital organ as "uncertain behavior," "borderline," or "indeterminate," and further specification is not provided. This applies when the physician's documentation aligns with the pathologist's inability to classify the tumor definitively.

• Always seek clarification from the pathologist or physician if a more specific diagnosis (benign or malignant) can be obtained.
• Avoid using this code if the documentation clearly states a benign or malignant diagnosis; instead, use the appropriate C (malignant) or D25-D28 (benign) codes.
• Ensure the documentation specifies a female genital organ; if the site is unknown or unspecified, a different "unspecified site" code for uncertain behavior would be more appropriate.
