Autoimmune hepatitis

This code identifies an inflammatory liver disease characterized by the immune system attacking healthy liver cells. It results in chronic inflammation and can lead to cirrhosis and liver failure if untreated. The condition is distinct from other forms of hepatitis, such as viral or alcoholic.

Apply this code for patients diagnosed with autoimmune hepatitis based on clinical presentation, elevated liver enzymes, autoantibodies (e.g., ANA, ASMA, anti-LKM1), and characteristic liver biopsy findings. Documentation should clearly indicate the autoimmune etiology of the liver inflammation.

• Do not confuse with other forms of chronic hepatitis (e.g., viral hepatitis B or C, alcoholic hepatitis) which have distinct codes.
• Always look for specific documentation of autoimmune markers or biopsy confirmation.
• Consider sequencing with codes for associated conditions or complications, such as cirrhosis (K74.-) if present.
