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

This code describes the presence of gallstones within the bile duct (choledocholithiasis) concurrently with inflammation of the gallbladder (cholecystitis). Importantly, the documentation does not specify the type of cholecystitis, and there is no mention of an obstruction caused by the calculus.

Use this code when documentation confirms both bile duct calculus and cholecystitis, but the physician does not specify whether the cholecystitis is acute or chronic. This code is appropriate when imaging or surgical findings identify choledocholithiasis and cholecystitis, and there is no evidence of bile duct obstruction.

• Ensure documentation explicitly states the presence of both bile duct calculus and cholecystitis.
• Do not use this code if the cholecystitis is specified as acute or chronic; instead, select a more specific code from the K80.4 series.
• Verify that the documentation explicitly states "without obstruction" or implies its absence; otherwise, a code indicating obstruction may be more appropriate.
