Biliary cirrhosis, unspecified

This code represents a chronic, progressive liver disease characterized by inflammation and destruction of the small bile ducts within the liver, leading to scarring (cirrhosis) and impaired bile flow. It signifies a stage of liver damage where the specific type of biliary cirrhosis (e.g., primary or secondary) has not been documented or determined.

Assign this code when documentation indicates biliary cirrhosis without further specification of its etiology. This is appropriate when the provider has diagnosed biliary cirrhosis but has not yet identified it as primary biliary cholangitis (PBC) or secondary biliary cirrhosis. Supporting documentation would include physician notes stating "biliary cirrhosis, unspecified" or "cirrhosis due to biliary disease, type unknown."

• Do not use this code if the documentation specifies primary biliary cholangitis (PBC); instead, use K74.3.
• Avoid using this code if the cause of the biliary obstruction leading to cirrhosis is known and documented (e.g., choledocholithiasis, stricture); in such cases, code the underlying cause and the resulting secondary biliary cirrhosis (K74.4).
• Always query the provider for greater specificity if "biliary cirrhosis" is documented without further clarification to determine if it is primary or secondary.
