Benign neoplasm of unspecified ovary

This code signifies a non-cancerous growth originating in an ovary where the specific laterality (left or right) is not documented. These benign neoplasms are typically discovered incidentally during imaging or gynecological examination and may or may not cause symptoms.

Apply this code when medical record documentation confirms a benign ovarian neoplasm, but the physician's notes do not specify which ovary is affected. This is often used when imaging reports or operative notes simply state "benign ovarian mass" without further laterality detail.

• Avoid using this code if laterality (left or right ovary) is clearly documented; instead, choose the more specific D27.0 (left) or D27.1 (right).
• Ensure the pathology report or physician's final diagnosis explicitly states "benign" to differentiate from malignant or uncertain behavior neoplasms.
• Do not use this code for ovarian cysts without a definitive diagnosis of a benign neoplasm; refer to codes in the N83 series for non-neoplastic ovarian cysts.
