Chronic persistent hepatitis, not elsewhere classified

This code signifies a long-standing inflammation of the liver that persists for at least six months, characterized by ongoing liver cell damage and inflammation. It represents a chronic form of hepatitis that does not fit into other specific categories of liver disease.

Assign this code when documentation indicates chronic hepatitis without a specified etiology (e.g., viral, autoimmune, alcoholic). This diagnosis is typically supported by liver biopsy findings showing persistent inflammation and necrosis, or by elevated liver enzymes and serological markers over an extended period.

• Ensure documentation clearly states "chronic persistent hepatitis" and explicitly excludes other specific causes.
• Do not use this code if a more specific type of chronic hepatitis (e.g., viral, autoimmune, drug-induced) is identified.
• Consider sequencing this code after any underlying conditions that may contribute to the chronic hepatitis, if applicable.
