ICD-10 Code D25.1 – Intramural leiomyoma of uterus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D25.1 – Intramural leiomyoma of uterus
What it is
D25.1 identifies a benign smooth muscle tumor, or fibroid, located within the muscular wall of the uterus. It is used when documentation specifies an intramural uterine leiomyoma.
Clinical signs
Clinical features vary; refer to documentation. Common references describe abnormal uterine bleeding, pelvic pressure, or an enlarged, irregular uterus, but the diagnosis should be supported by imaging or clinician assessment.
When to use this code
Use D25.1 when the provider documents an intramural leiomyoma, intramural fibroid, or a fibroid centered in the uterine myometrium. Code it when the record clearly distinguishes this location from submucosal, subserosal, or unspecified uterine leiomyoma. If the site is not stated, check documentation.
Do not use for
Do not use D25.1 for uterine leiomyomas with a different location, such as submucous or subserous tumors. Avoid this code when the chart only says “fibroid uterus” or “leiomyoma” without location.
Coding tip
Confirm the exact uterine location in the note or imaging report before assigning D25.1.
