Benign neoplasm of ovary

This code signifies the presence of a non-cancerous growth or tumor originating in the ovary. These benign neoplasms are typically slow-growing and do not metastasize to other parts of the body, distinguishing them from malignant ovarian tumors.

Apply this code when documentation clearly indicates a benign ovarian mass, cyst, or tumor identified through imaging, surgical pathology, or clinical examination. This code is appropriate for conditions such as serous cystadenoma, mucinous cystadenoma, or mature cystic teratoma (dermoid cyst) of the ovary.

• Ensure pathology reports explicitly state "benign" to avoid miscoding.
• Do not use this code for ovarian cysts that are physiological (e.g., follicular cysts, corpus luteum cysts) unless they are specifically identified as neoplastic.
• If the laterality (left or right ovary) is specified, consider if a more specific ICD-9-CM code is available for laterality.
