Fistula of bile duct

This code represents an abnormal, pathological connection between a bile duct and another organ or the skin. This can result in the leakage of bile, leading to symptoms such as pain, infection, or jaundice, depending on the location and nature of the fistula.

Use this code when documentation clearly indicates the presence of a fistula involving any part of the biliary tree. This includes internal fistulas (e.g., choledochoduodenal fistula) and external fistulas (e.g., biliary-cutaneous fistula). Supporting documentation should specify the presence of the fistula and its location.

• Differentiate from other biliary tract disorders such as strictures or obstructions, which have distinct codes.
• If the fistula is a complication of a procedure, consider sequencing the complication code first, followed by this code, if applicable.
• Ensure the documentation specifies "fistula of bile duct" rather than a general "biliary leak" to support this specific diagnosis.
