ICD-10 Code D25.2 – Subserosal leiomyoma of uterus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D25.2 – Subserosal leiomyoma of uterus
What it is
D25.2 identifies a benign smooth muscle tumor of the uterus that grows on the outer surface, or serosal side, of the uterus. It is a fibroid located beneath the outer lining rather than within the cavity.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a palpable pelvic mass, pressure symptoms, or imaging evidence of a uterine fibroid arising from the serosal surface.
When to use this code
Use D25.2 when the provider documents a subserosal uterine leiomyoma or imaging clearly localizes the fibroid to the outer uterine wall. You may also use it when the diagnosis is confirmed in operative or pathology documentation. Check documentation if the location is not specified.
Do not use for
Do not use this code for intramural, submucosal, or unspecified uterine leiomyomas. If the record only says “uterine fibroid” without location, check documentation before assigning D25.2.
Coding tip
Code the fibroid location exactly as documented, because leiomyoma codes depend on whether it is subserosal, intramural, or submucosal.
