ICD-10 Code D25 – Leiomyoma of uterus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D25 – Leiomyoma of uterus
What it is
D25 identifies a benign smooth muscle tumor of the uterus, also called a uterine fibroid or leiomyoma. It is used when documentation confirms a noncancerous uterine mass arising from myometrial tissue.
Clinical signs
Clinical features vary; refer to documentation. Common findings include an enlarged or irregularly shaped uterus, pelvic pressure, and abnormal uterine bleeding. Imaging or gynecologic examination may support the diagnosis.
When to use this code
Use D25 when the record clearly states uterine leiomyoma, fibroid, or myoma. Assign it for confirmed benign uterine tumors, whether found during evaluation for bleeding, pain, pressure, or incidental imaging.
Choose the code that matches the documented site or type if the record provides more detail. If the note only says “uterine mass” without confirmation, check documentation before coding D25.
Do not use for
Do not use D25 for malignant uterine neoplasms, unspecified pelvic masses, or nonuterine fibroids. If the diagnosis is uncertain or the location is not documented, check documentation.
Coding tip
Code D25 only when the provider documents a uterine leiomyoma diagnosis, not merely suspected fibroids or imaging findings alone.
