Question: The physician's documentation shows a neoplasm with uncertain behavior of the female genital organs. Which diagnosis code(s) should I select? Do you have any helpful diagnoses guidelines for this code(s)? Georgia Subscriber Answer: The diagnosis codes from which you should select include but are not limited to: Check the subhead under which you find these codes for other relevant codes for unspecified behavior of a neoplasm in the ovaries or fallopian tubes or any other genital organs. These codes do not describe the differential diagnosis of patients with pelvic masses and sensitivity, so you want to verify that the neoplasm's presence is in a genital organ.
