ICD-10 Code D27.1 – Benign neoplasm of left ovary (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D27.1 – Benign neoplasm of left ovary
What it is
D27.1 identifies a noncancerous tumor of the left ovary. Use this code when documentation clearly states a benign ovarian neoplasm on the left side.
Clinical signs
Clinical features vary; refer to documentation. Patients may be asymptomatic or have pelvic pain, bloating, or an adnexal mass found on exam or imaging.
When to use this code
Use D27.1 when the provider documents a benign neoplasm limited to the left ovary. It is appropriate for confirmed pathology, imaging-supported diagnosis, or a clearly recorded clinical impression of a benign left ovarian tumor. If the record only says ovarian cyst or mass, check documentation before coding.
Do not use for
Do not use this code for malignant ovarian tumors, uncertain behavior neoplasms, or benign neoplasms of the right ovary or unspecified ovary. Check documentation if laterality is not clearly stated.
Coding tip
Always verify laterality and whether the provider documented benign neoplasm rather than cyst, mass, or neoplasm of uncertain behavior.
