Is D26.9 an HCC code?
No. D26.9 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
D26.9 is the ICD-10-CM diagnosis code for other benign neoplasm of uterus, unspecified. A non-cancerous tumor or growth in the uterus (womb) that has not been specifically identified or classified. This is a benign condition meaning it is not cancer and typically does not spread to other parts of the body. D26.9 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D26.9 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code only when the specific type of benign uterine neoplasm cannot be determined or is not documented; if the neoplasm type is known (such as fibroid, polyp, or leiomyoma), use the more specific D26 subcategory code instead.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D26.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the specific type of benign uterine neoplasm cannot be determined or is not documented; if the neoplasm type is known (such as fibroid, polyp, or leiomyoma), use the more specific D26 subcategory code instead
- •Verify documentation for any imaging or pathology reports that might specify the exact nature of the uterine growth, as this could allow for more precise coding with a higher specificity code
