Toxic liver disease with chronic lobular hepatitis

This code signifies liver damage resulting from exposure to toxins, specifically manifesting as chronic inflammation primarily affecting the liver lobules. It indicates persistent, long-term inflammation and damage to the liver's functional units due to an identified toxic agent.

Apply this code when documentation clearly links chronic lobular hepatitis to a specific toxic exposure (e.g., drugs, chemicals, environmental toxins). Supporting documentation should include a definitive diagnosis of chronic lobular hepatitis and a confirmed toxic etiology.

• Ensure the documentation explicitly states "chronic lobular hepatitis" and identifies a toxic cause.
• Distinguish from acute toxic liver injury or other forms of chronic hepatitis not specifically lobular.
• Code the specific toxic agent (e.g., drug, chemical) as an additional diagnosis, if known and documented, using codes from Chapter 20 (External Causes of Morbidity).
