Calculus of GB and bile duct w acute cholecyst w/o obst

This diagnosis code signifies the presence of gallstones within both the gallbladder and the bile ducts, accompanied by an acute inflammation of the gallbladder. Importantly, there is no evidence of a blockage or obstruction of the bile flow associated with this condition.

Apply this code when documentation clearly indicates cholelithiasis affecting both the gallbladder and the common bile duct, alongside a diagnosis of acute cholecystitis. This is appropriate when imaging studies and clinical findings confirm inflammation but rule out any obstructive pathology.

• Ensure documentation explicitly states "without obstruction" to differentiate from codes indicating obstruction.
• Verify that both gallbladder and bile duct calculi are present, not just one or the other.
• Do not use if the cholecystitis is chronic or if there is no acute inflammatory component.
