Is K68.9 an HCC code?
No. K68.9 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.

What This Code Means
K68.9 is the ICD-10-CM diagnosis code for other disorders of retroperitoneum. Other unspecified disorders or conditions affecting the retroperitoneal space that do not fit into more specific categories. K68.9 sits in the ICD-10-CM chapter for diseases of the digestive system (k00-k95), within the section covering diseases of peritoneum and retroperitoneum (k65-k68).
K68.9 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 a more specific retroperitoneal disorder code is not applicable.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for K68.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
