0.000What This Code Means
A chronic liver disease where the body's immune system attacks liver cells, causing inflammation and damage. This autoimmune condition requires ongoing monitoring and treatment.
Coding Tips
- •Verify autoimmune markers (anti-smooth muscle antibodies, anti-nuclear antibodies) are documented in the medical record
- •Note the disease stage or severity if documented (mild, moderate, severe, or with cirrhosis)
Clinical Significance
Autoimmune hepatitis is a chronic condition where the immune system attacks liver cells, potentially progressing to cirrhosis without treatment. This diagnosis requires immunosuppressive therapy and lifelong monitoring, significantly impacting care complexity and patient outcomes.
Documentation Requirements
- ✓Positive autoimmune markers (ANA, ASMA, anti-LKM, anti-SLA)
- ✓Elevated serum immunoglobulin G levels
- ✓Interface hepatitis on liver biopsy
- ✓Exclusion of viral hepatitis and other causes
- ✓Elevated transaminases (ALT, AST)
- ✓Response to corticosteroid or immunosuppressive therapy
- ✓Clinical presentation with fatigue, jaundice, or hepatomegaly
- ✓Histological features of chronic active hepatitis
