This code is used in medical coding to identify cases of chronic hepatitis that are caused by viral infections not specifically categorized under other codes, such as hepatitis A, B, or C.

Clinical Description

Definition

Chronic viral hepatitis is a long-term inflammation of the liver caused by viral infections. The condition can lead to significant liver damage, cirrhosis, and even liver cancer if not managed properly. The term "other chronic viral hepatitis" encompasses various viral etiologies that do not fall under the more commonly recognized types of hepatitis, such as hepatitis A (B15), B (B16), or C (B17).

Etiology

The viruses that may cause chronic hepatitis but are not classified under the standard codes include:
- Hepatitis D virus (HDV)
- Hepatitis E virus (HEV)
- Other unidentified or less common viral agents

These viruses can lead to chronic liver disease, particularly in individuals with pre-existing liver conditions or those who are immunocompromised.

Symptoms

Patients with chronic viral hepatitis may experience a range of symptoms, which can vary in severity:
- Fatigue
- Jaundice (yellowing of the skin and eyes)
