Obstruction of bile duct

This code signifies a blockage within the bile duct system, which can impede the flow of bile from the liver and gallbladder to the small intestine. This obstruction can lead to a buildup of bilirubin and other substances, potentially causing jaundice, pain, and liver dysfunction.

Assign this code when documentation clearly indicates a diagnosis of bile duct obstruction, regardless of the underlying cause. This includes scenarios such as choledocholithiasis, strictures, or external compression. Supporting documentation should specify the presence of an obstruction within the biliary tree.

• Do not use this code for conditions like cholelithiasis without documented obstruction.
• Consider sequencing this code after the underlying cause of the obstruction, if known (e.g., gallstones, tumor).
• Ensure documentation specifies "obstruction" rather than just inflammation or presence of stones.
