What This Code Means
E51.11 is the ICD-10-CM diagnosis code for dry beriberi. Dry beriberi is a neurological form of thiamine (vitamin B1) deficiency that causes nerve damage, weakness, and numbness, typically affecting the legs and feet. E51.11 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering other nutritional deficiencies (e50-e64).
E51.11 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.
Distinguish between dry beriberi (E51.11) and wet beriberi (E51.12) based on whether cardiac symptoms are present.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for E51.11 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Distinguish between dry beriberi (E51.11) and wet beriberi (E51.12) based on whether cardiac symptoms are present
- •Document the underlying cause of thiamine deficiency (alcoholism, malnutrition, dialysis) for more complete coding
