Neoplasm of uncertain behavior of other and unspecified female genital organs

This code signifies a tumor originating in female reproductive organs, excluding the ovary, uterus, placenta, and specified sites like the vulva or vagina, where the pathologist cannot definitively classify it as benign or malignant. It indicates that the biological behavior of the neoplasm is currently indeterminate, requiring further investigation or follow-up.

Assign this code when pathology reports describe a neoplasm of uncertain behavior found in female genital organs such as the fallopian tube, broad ligament, round ligament, or parametrium. This code is appropriate when the documentation explicitly states "uncertain behavior," "borderline malignancy," or "of unknown malignant potential" for these specific sites.

• Do not use this code for neoplasms of uncertain behavior of the ovary (236.2), uterus (236.0), or placenta (236.1).
• Ensure the documentation clearly specifies "uncertain behavior" and the affected female genital organ is not otherwise classified.
• If a definitive diagnosis of benign or malignant is later established, update the code accordingly.
