ICD-10 Code K74.5 – Biliary cirrhosis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K74.5 – Biliary cirrhosis, unspecified
What it is
K74.5 identifies biliary cirrhosis when the record does not specify a more precise type. It refers to chronic liver scarring associated with bile duct disease or impaired bile flow.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include chronic cholestatic liver disease, jaundice, pruritus, fatigue, and evidence of progressive hepatic fibrosis or cirrhosis.
When to use this code
Use K74.5 when the provider documents biliary cirrhosis without naming primary biliary cholangitis or another specific subtype. It is also appropriate when the chart confirms biliary cirrhosis but does not provide enough detail for a more specific code. Check documentation if the cause is unclear.
Do not use for
Do not use this code for general cirrhosis without biliary involvement, or for a more specific biliary cirrhosis diagnosis when documented. If the record only says liver disease or fibrosis, code the documented condition instead.
Coding tip
Look for exact provider wording and code the most specific cirrhosis type supported by the note.
