Is K28.7 an HCC code?
No. K28.7 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
K28.7 is the ICD-10-CM diagnosis code for chronic gastrojejunal ulcer without hemorrhage or perforation. A long-term gastrojejunal ulcer without bleeding or perforation. K28.7 sits in the ICD-10-CM chapter for diseases of the digestive system (k00-k95), within the section covering diseases of esophagus, stomach and duodenum (k20-k31).
K28.7 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 for chronic gastrojejunal ulcer when no hemorrhage or perforation is present.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for K28.7 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
