ICD-10 Code D25.0 – Submucous leiomyoma of uterus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D25.0 – Submucous leiomyoma of uterus
What it is
D25.0 identifies a benign smooth-muscle tumor of the uterus that lies just beneath the endometrial lining. It is a specific type of uterine leiomyoma, often called a fibroid.
Clinical signs
Common findings include abnormal uterine bleeding, pelvic pressure, and infertility or recurrent pregnancy loss. Imaging or hysteroscopic documentation should support the submucous location; clinical features vary, refer to documentation.
When to use this code
Use D25.0 when the provider documents a submucous uterine leiomyoma, or when imaging clearly identifies a fibroid projecting into the uterine cavity. Code it when the record specifies this location rather than a general uterine fibroid.
If the note only says “fibroid uterus” or “uterine leiomyoma” without location, check documentation before assigning D25.0. The exact site matters because other leiomyoma codes describe different uterine locations.
Do not use for
Do not use D25.0 for intramural, subserosal, or unspecified uterine leiomyomas. Also avoid it if documentation refers to a non-uterine mass or a malignant uterine neoplasm.
Coding tip
Confirm the fibroid’s location in the operative report, imaging, or assessment before choosing D25.0.
