ICD-10 Code D12.0 – Benign neoplasm of cecum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D12.0 – Benign neoplasm of cecum
What it is
D12.0 identifies a noncancerous tumor in the cecum, the first part of the large intestine. Use it when documentation states a benign neoplasm of the cecum or a benign cecal polyp.
Clinical signs
Clinical features vary; refer to documentation. These lesions are often found during colonoscopy or imaging and may be asymptomatic, or associated with bleeding, anemia, or bowel habit changes.
When to use this code
Use D12.0 when the provider documents a benign neoplasm specifically located in the cecum. It is also appropriate when pathology confirms a benign cecal tumor and no malignant behavior is reported.
Code the documented site as written. If the record only says “colon polyp” or the exact cecal location is unclear, check documentation before assigning D12.0.
Do not use for
Do not use D12.0 for malignant neoplasms, dysplasia, or inflammatory bowel disease. Do not assign it when the lesion is in another colonic site or the documentation does not confirm the cecum.
Coding tip
Verify the pathology or endoscopy report for the exact site and benign nature before you code D12.0.
