Obstruction of bile duct

This code represents a blockage within the bile ducts, preventing the normal flow of bile from the liver to the small intestine. This obstruction can lead to jaundice, abdominal pain, and impaired digestion. It encompasses various causes of acquired bile duct obstruction, excluding those due to gallstones or congenital anomalies.

Use this code for documented cases of acquired bile duct obstruction, such as those caused by strictures, tumors, parasites, or inflammation, when cholelithiasis is explicitly ruled out. Documentation should clearly state "obstruction of bile duct" and specify the underlying cause if known and not separately coded.

• Do not use this code if the obstruction is due to gallstones; instead, refer to the K80.- series.
• Avoid using this code for congenital bile duct obstructions; refer to Q44.3.
• Always seek to code the underlying cause of the obstruction if known and documented (e.g., neoplasm, stricture) in addition to this code.
