ICD-10 Code D26.1 – Other benign neoplasm of corpus uteri (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D26.1 – Other benign neoplasm of corpus uteri
What it is
D26.1 identifies a noncancerous tumor in the body of the uterus. Use it when documentation states a benign neoplasm of the corpus uteri, including unspecified benign growths in that location.
Clinical signs
Clinical features vary; refer to documentation. Benign uterine tumors may be found on imaging, pelvic examination, or pathology, and they can be asymptomatic or associated with abnormal uterine bleeding or pelvic pressure.
When to use this code
Use D26.1 when the provider documents a benign neoplasm arising in the corpus uteri and does not name a more specific site or type. It also fits confirmed pathology reports describing a benign uterine body tumor.
Code this only when the record supports a benign neoplasm, not a suspected mass or a general uterine lesion. If the documentation is unclear about location or behavior, check documentation before assigning the code.
Do not use for
Do not use D26.1 for malignant uterine tumors, leiomyoma, or endometrial hyperplasia. If the lesion is not documented as benign or is located outside the corpus uteri, choose the more accurate code.
Coding tip
Verify both behavior and site in the pathology or provider note before coding; benign does not automatically mean D26.1.
