What This Code Means
D13.39 is the ICD-10-CM diagnosis code for benign neoplasm of other parts of small intestine. A noncancerous tumor in a specific part of the small intestine, such as the jejunum or ileum. D13.39 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D13.39 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 when the small intestine location is specified but not the duodenum.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D13.39 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code when the small intestine location is specified but not the duodenum
- •Document the specific segment (jejunum, ileum, or other) when available for clinical clarity
