Encounter for prophylactic removal of ovary(s)

This diagnosis code signifies a patient encounter for the surgical removal of one or both ovaries performed as a preventive measure. It indicates that the procedure is undertaken to avert the potential development of a disease, rather than to treat an existing condition.

Apply this code when a patient undergoes an oophorectomy due to a significantly elevated risk of ovarian cancer, such as in cases of BRCA1 or BRCA2 gene mutations, or a strong family history of the disease. It is also appropriate for prophylactic removal in patients with endometriosis or other conditions where future malignancy is a concern.

• Always confirm the intent of the surgery was prophylactic, not therapeutic.
• Do not use this code if the patient has a confirmed diagnosis of ovarian cancer or another ovarian pathology requiring removal.
• Consider sequencing this code with a personal or family history code (e.g., Z80.41, Z80.42) to provide further clinical context.
