What This Code Means
E78 is the ICD-10-CM diagnosis code for disorders of lipoprotein metabolism and other lipidemias. E78 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering metabolic disorders (e70-e88).
Header codes like E78 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 E78 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
