K80.5: Calculus of bile duct without cholangitis or cholecystitis

Calculus of bile duct without cholangitis or cholecystitis, often referred to as a bile duct stone, is a specific medical condition involving the formation of hard, stone-like substances in the bile duct. These stones result from an accumulation of digestive fluids within the bile duct, a tube that carries bile from the liver and gallbladder to the small intestine. This condition tends to occur when the bile contains too much cholesterol or bilirubin and not enough bile salts. Common symptoms usually involve abdominal pain particularly in the upper right area, fever, jaundice (a yellowing of the skin and eyes), and changes in urine and stool color. While this condition can occur without inflammation, it can sometimes lead to serious complications if the stone hinders the free flow of bile.
