ICD-10 Code E51.12 – Wet beriberi (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E51.12 – Wet beriberi
What it is
Wet beriberi is a thiamine deficiency disorder that affects the cardiovascular system. It is used when documentation identifies beriberi with cardiac involvement.
Clinical signs
Clinical features vary; refer to documentation. Commonly described findings include edema, tachycardia, and signs of heart failure related to thiamine deficiency.
When to use this code
Use this code when the provider documents wet beriberi, cardiac beriberi, or thiamine deficiency with cardiovascular manifestations. It may also apply when the record clearly links beriberi to edema or heart failure. Check documentation if the type is not specified.
Do not use for
Do not use this code for dry beriberi, nonspecific malnutrition, or thiamine deficiency without cardiac involvement. If the note only says “beriberi” and does not identify wet form, check documentation.
Coding tip
Code E51.12 only when the record supports a wet, cardiac presentation of beriberi.
