ICD-10 Code D27 – Benign neoplasm of ovary (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D27 – Benign neoplasm of ovary
What it is
D27 identifies a noncancerous tumor of the ovary. It is used when documentation confirms a benign ovarian neoplasm, without evidence of malignant behavior.
Clinical signs
Clinical features vary; refer to documentation. Patients may have an adnexal mass, pelvic pressure, abdominal bloating, or incidental imaging findings, but the diagnosis must be confirmed as benign.
When to use this code
Use D27 when the provider documents a benign ovarian neoplasm, such as a benign tumor or cystic neoplasm, and no malignant or uncertain behavior is stated. Code it from pathology, imaging, or operative findings when the record clearly supports benignity.
If laterality or more specific histology is documented, follow the record and assign the most specific code available. Check documentation when the ovarian lesion is described only as a mass or adnexal cyst.
Do not use for
Do not use D27 for malignant ovarian tumors, borderline tumors, or neoplasms of uncertain behavior. Also avoid it when the chart only says “ovarian mass” without confirming a benign neoplasm.
Coding tip
Verify the pathology or provider diagnosis before assigning D27, and do not code a benign neoplasm from imaging impression alone if the record is unclear.
