Calculus of GB and bile duct w acute cholecyst w obstruction

This code signifies the presence of gallstones within both the gallbladder and the bile duct, concurrently causing acute inflammation of the gallbladder (cholecystitis) and an obstruction of the bile flow. This is a severe form of gallstone disease, often presenting with significant pain and systemic symptoms.

Use this code when documentation clearly indicates cholelithiasis affecting both the gallbladder and the common bile duct, alongside a diagnosis of acute cholecystitis and evidence of biliary obstruction. This typically occurs in patients presenting with acute right upper quadrant pain, fever, elevated white blood cell count, and imaging (e.g., ultrasound, MRCP) confirming stones in both locations with signs of acute inflammation and obstruction.

• Ensure documentation explicitly states "acute" cholecystitis and "obstruction" in addition to stones in both locations.
• Distinguish from codes for cholelithiasis without obstruction or without acute cholecystitis, or stones confined to only one location.
• Consider sequencing with codes for associated complications, such as cholangitis or pancreatitis, if documented.
