What This Code Means
K50.11 is the ICD-10-CM diagnosis code for crohn's disease of large intestine with complications. K50.11 sits in the ICD-10-CM chapter for diseases of the digestive system (k00-k95), within the section covering noninfective enteritis and colitis (k50-k52).
Header codes like K50.11 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for K50.11 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
