Calculus of bile duct w cholangitis, unsp, w/o obstruction

This code signifies the presence of gallstones within the bile duct (choledocholithiasis) accompanied by inflammation of the bile ducts (cholangitis). Importantly, it indicates that there is no documented obstruction of the bile duct and the specific type of cholangitis is not specified.

Use this code when documentation clearly states both choledocholithiasis and cholangitis without mention of an obstruction. This typically applies to patients presenting with symptoms like fever, jaundice, and right upper quadrant pain, where imaging confirms bile duct stones and laboratory tests indicate inflammation, but no blockage is identified.

• Ensure documentation explicitly states "without obstruction" to use this specific code. If obstruction is present, a different code from the K80.3 series would be more appropriate.
• If the type of cholangitis (e.g., acute, chronic, suppurative) is specified, a more precise code should be selected.
• Always review the operative report or imaging findings to confirm the presence or absence of obstruction.
