Code Description

ICD-10 E51.1 is a billable code used to indicate a diagnosis of beriberi.

Key Diagnostic Point:

Beriberi is a disease caused by a deficiency of thiamine (vitamin B1), which is essential for carbohydrate metabolism and nerve function. The condition can manifest in two primary forms: wet beriberi, which affects the cardiovascular system, leading to symptoms such as edema, heart failure, and increased heart rate; and dry beriberi, which primarily impacts the nervous system, resulting in peripheral neuropathy, muscle weakness, and ataxia. Beriberi is often seen in populations with a high intake of polished rice, which lacks thiamine, and in individuals with malabsorption syndromes, chronic alcoholism, or those on parenteral nutrition without adequate vitamin supplementation. Diagnosis is typically based on clinical presentation and dietary history, and treatment involves thiamine supplementation and dietary modifications to include thiamine-rich foods such as whole grains, legumes, nuts, and seeds. Early recognition and intervention are crucial to prevent irreversible neurological damage.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between wet and dry beriberi for accurate coding.
  • Understanding the underlying causes of thiamine deficiency.
  • Documenting dietary history and supplementation accurately.
  • Recognizing associated conditions that may complicate the diagnosis.

Audit Risk Factors

  • Inadequate documentation of dietary history.
  • Failure to specify the type of beriberi.
  • Lack of evidence for thiamine supplementation.
  • Misclassification of symptoms related to other conditions.

Frequently Asked Questions

What are the symptoms of beriberi?

Symptoms of beriberi can vary based on the type. Wet beriberi typically presents with cardiovascular symptoms such as edema and heart failure, while dry beriberi presents with neurological symptoms like peripheral neuropathy and muscle weakness.

How is beriberi treated?

Treatment for beriberi involves thiamine supplementation and dietary changes to include thiamine-rich foods. In severe cases, hospitalization may be required for intravenous thiamine administration.
