ICD-10 Code K74.4 – Secondary biliary cirrhosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K74.4 – Secondary biliary cirrhosis
What it is
Use this code for cirrhosis that develops because bile flow has been blocked or impaired over time. It reflects chronic liver scarring caused by a biliary disorder, not primary liver disease.
Clinical signs
Typical findings include chronic cholestasis, jaundice, pruritus, and evidence of progressive liver fibrosis or cirrhosis. Clinical features vary; refer to documentation.
When to use this code
Assign K74.4 when the provider documents secondary biliary cirrhosis, biliary cirrhosis due to obstruction, or cirrhosis from a known bile duct problem. Use it when the record links cirrhosis to an underlying biliary cause. If the cause is not clearly stated, check documentation.
Do not use for
Do not use this code for primary biliary cholangitis or other cirrhosis types without a documented biliary cause. Do not assume secondary biliary cirrhosis from abnormal liver tests alone.
Coding tip
Verify that the record names both cirrhosis and a secondary biliary cause before you assign K74.4.
