Fistula of bile duct

This code represents an abnormal, often pathological, connection or tract that forms between a bile duct and another organ, body surface, or cavity. This can result in the leakage of bile outside its normal pathway, leading to various complications.

Use this code when documentation clearly indicates the presence of a fistula originating from a bile duct. This includes scenarios such as a choledochoduodenal fistula, a biliary-cutaneous fistula, or a fistula to another internal organ. Supporting documentation should specify the bile duct as the origin of the fistula.

• Differentiate from fistulas involving other parts of the digestive system; ensure the bile duct is explicitly stated as the origin.
• Consider additional codes for the underlying cause of the fistula (e.g., trauma, infection, surgical complication) if known and documented.
• Review operative reports and imaging studies (e.g., cholangiography) for definitive diagnosis and anatomical details.
