Secondary biliary cirrhosis
ICD-10 K74.4 is a billable code used to indicate a diagnosis of secondary biliary cirrhosis.
Secondary biliary cirrhosis (K74.4) is a liver condition characterized by the progressive scarring (fibrosis) of the liver due to prolonged obstruction of the bile ducts. This obstruction can arise from various causes, including gallstones, strictures, or tumors that impede bile flow. Clinically, patients may present with symptoms such as jaundice, pruritus, abdominal pain, and fatigue. The anatomy involved primarily includes the liver and biliary system, where bile produced by the liver is stored in the gallbladder and transported through the bile ducts. Over time, the continued obstruction leads to increased pressure in the bile ducts, resulting in liver cell damage and eventual cirrhosis. Diagnostic considerations for K74.4 include imaging studies such as ultrasound, CT scans, or MRCP to identify the cause of bile duct obstruction, along with liver function tests to assess the extent of liver damage. A liver biopsy may also be performed to confirm the diagnosis and evaluate the degree of fibrosis.

K74.4 encompasses cirrhosis resulting from secondary causes of biliary obstruction, including but not limited to gallstones, strictures, and malignancies affecting the bile ducts.
K74.4 should be used when cirrhosis is specifically due to secondary biliary obstruction, as opposed to primary biliary cirrhosis (K74.3) or cirrhosis due to other etiologies.
Documentation should include clinical findings, imaging results indicating bile duct obstruction, liver function test results, and any relevant history of biliary disease or interventions.
