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

This code signifies the presence of gallstones within the bile duct (choledocholithiasis) concurrently with inflammation of the gallbladder that exhibits both acute and chronic features. Importantly, there is no blockage of the bile flow associated with these conditions.

Apply this code when documentation clearly indicates choledocholithiasis alongside cholecystitis described as both acute and chronic, and explicitly states the absence of obstruction. This scenario often arises when patients present with symptoms like abdominal pain, fever, and jaundice, but imaging studies confirm stones in the bile duct without evidence of bile flow impediment.

• Ensure documentation specifies both acute and chronic cholecystitis. If only one is mentioned, a different code is required.
• Verify the absence of obstruction is explicitly stated or clearly implied by the clinical findings and imaging reports.
• Do not use this code if the calculus is in the gallbladder (cholelithiasis) rather than the bile duct.
