0.000What This Code Means
Cirrhosis of the liver caused by obstruction or damage to the bile ducts from another condition, such as gallstones or strictures.
Coding Tips
- •Identify and document the underlying cause of bile duct obstruction or damage when possible
- •Distinguish from K74.3 (primary biliary cirrhosis) which is autoimmune in origin
Clinical Significance
Secondary biliary cirrhosis results from chronic bile duct obstruction or damage from external causes, leading to progressive liver scarring and dysfunction. This condition requires treatment of the underlying obstruction and monitoring for cirrhosis complications.
Documentation Requirements
- ✓Evidence of bile duct obstruction or external biliary tract damage
- ✓Imaging showing biliary dilation or strictures
- ✓History of biliary surgery, stones, or strictures
- ✓Elevated alkaline phosphatase and bilirubin levels
- ✓Liver biopsy showing portal fibrosis and bile duct proliferation
- ✓Documentation of underlying obstructive cause
- ✓Clinical presentation with jaundice or cholestasis
- ✓Exclusion of primary biliary cirrhosis (negative AMA)
Commonly Confused Codes
K74.3 — Primary biliary cirrhosis is autoimmune rather than obstructiveK74.5 — Biliary cirrhosis unspecified when primary vs secondary not documentedK83.1 — Bile duct obstruction without established cirrhosisK74.60 — Unspecified cirrhosis when biliary nature not documentedK76.6 — Portal hypertension may be consequence but not the primary diagnosis
