What This Code Means

E79.0 is the ICD-10-CM diagnosis code for hyperuricemia without signs of inflammatory arthritis and tophaceous disease. A condition characterized by elevated uric acid levels in the blood without causing joint inflammation or gout deposits. E79.0 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering metabolic disorders (e70-e88).

E79.0 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

Verify that the patient does not have inflammatory arthritis or tophi before assigning this code.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for E79.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
