Calculus of bile duct w chronic cholecyst w/o obstruction

This code signifies the presence of gallstones within the bile duct (choledocholithiasis) in a patient also diagnosed with long-standing inflammation of the gallbladder (chronic cholecystitis). Importantly, there is no indication of a blockage or obstruction caused by these calculi.

Use this code when documentation clearly states both chronic cholecystitis and choledocholithiasis without any mention of obstruction. This typically applies to patients experiencing symptoms related to these conditions, but without acute obstructive complications like jaundice or cholangitis.

• Ensure documentation explicitly states "without obstruction" to use this specific code.
• Do not use this code if acute cholecystitis is present; refer to codes within K80.3-K80.8.
• If obstruction is noted, a different code from the K80.5 series would be more appropriate.
