Calculus of bile duct w chronic cholecystitis w obstruction

This code signifies the presence of gallstones within the bile duct, accompanied by persistent inflammation of the gallbladder and a blockage in the bile flow. It describes a complex biliary condition involving both choledocholithiasis and chronic cholecystitis, complicated by obstruction.

Apply this code when documentation clearly indicates stones in the common bile duct, long-standing gallbladder inflammation, and evidence of biliary obstruction (e.g., elevated bilirubin, dilated ducts, jaundice). This diagnosis is typically supported by imaging studies (ultrasound, MRCP, ERCP) and clinical findings.

• Ensure documentation specifies chronic cholecystitis, not acute.
• Verify the obstruction is due to the calculus in the bile duct.
• Do not use this code if the cholecystitis is acute or if the obstruction is from a cause other than a bile duct stone.
