ICD-10 Code D27.9 – Benign neoplasm of unspecified ovary (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D27.9 – Benign neoplasm of unspecified ovary
What it is
D27.9 identifies a noncancerous ovarian tumor when the ovary is documented but the side is not specified. Use this code for benign neoplasm of the ovary without further laterality detail.
Clinical signs
Clinical features vary; refer to documentation. Patients may have an adnexal mass, pelvic discomfort, bloating, or an incidental imaging finding consistent with a benign ovarian lesion.
When to use this code
Use D27.9 when the provider documents a benign ovarian neoplasm and does not specify right or left ovary. It also fits cases where imaging or pathology confirms a benign ovarian tumor, but laterality is missing in the record. Check documentation before assigning a more specific code.
Do not use for
Do not use this code for malignant ovarian neoplasms, borderline tumors, or ovarian cysts without a documented neoplasm. If the ovary side is known, choose the laterality-specific code instead.
Coding tip
Query for laterality whenever the record says “ovarian benign tumor” but does not name the affected ovary.
