Calculus of GB and bile duct w ac and chr cholecyst w/o obst

This code signifies the presence of gallstones in both the gallbladder and the bile ducts, accompanied by inflammation of the gallbladder that exhibits both acute and chronic features. Importantly, there is no blockage of the bile flow associated with this condition.

Apply this code when documentation clearly indicates cholelithiasis and choledocholithiasis, along with a diagnosis of acute and chronic cholecystitis. This is appropriate when imaging or clinical findings confirm the absence of an obstruction, such as a dilated common bile duct or signs of cholangitis.

• Ensure documentation explicitly states both acute and chronic cholecystitis. If only one is present, a different code is required.
• Verify the absence of obstruction. If obstruction is present, a code from K80.3x, K80.4x, or K80.5x would be more appropriate.
• Do not use this code if the calculus is only in the gallbladder (K80.2x) or only in the bile duct (K80.5x).
