What This Code Means
K14 is the ICD-10-CM diagnosis code for diseases of tongue. K14 sits in the ICD-10-CM chapter for diseases of the digestive system (k00-k95), within the section covering diseases of oral cavity and salivary glands (k00-k14).
Header codes like K14 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 K14 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
