Calculus of bile duct w acute cholecystitis with obstruction

This code signifies the presence of gallstones (calculi) within the bile duct, concurrently with inflammation of the gallbladder (acute cholecystitis), and an obstruction of the bile flow. This is a complex condition involving both the common bile duct and the gallbladder, leading to acute symptoms.

Apply this code when documentation clearly indicates choledocholithiasis (bile duct stones) alongside acute cholecystitis and evidence of biliary obstruction. This typically presents with right upper quadrant pain, fever, jaundice, and elevated liver enzymes or bilirubin. Supporting documentation would include imaging reports (e.g., ultrasound, MRCP, ERCP) confirming stones in the bile duct and gallbladder inflammation, along with clinical notes detailing acute cholecystitis and obstructive symptoms.

• Ensure documentation specifies acute cholecystitis; chronic cholecystitis with obstruction and bile duct stones would be coded differently.
• Verify the location of the calculus is explicitly stated as the bile duct, not solely the gallbladder.
• Confirm the presence of obstruction, as this is a key component of the code description.
