Wet beriberi

This code represents wet beriberi, a severe form of thiamine (vitamin B1) deficiency characterized by cardiovascular manifestations. Patients typically present with symptoms such as edema, tachycardia, dyspnea, and cardiomegaly, which can lead to high-output heart failure.

Use this code when documentation clearly indicates a diagnosis of wet beriberi due to thiamine deficiency, specifically noting the presence of cardiovascular involvement. This diagnosis is often supported by clinical findings of heart failure, peripheral edema, and a history of inadequate thiamine intake (e.g., chronic alcoholism, restrictive diets).

• Ensure documentation specifies "wet" beriberi to differentiate from other forms of thiamine deficiency.
• Consider co-reporting codes for underlying causes of thiamine deficiency, such as chronic alcoholism (e.g., F10.20).
• Distinguish from "dry beriberi" (E51.11), which primarily affects the nervous system.
