Calculus of bile duct w cholecystitis, unsp, w obstruction

This code signifies the presence of gallstones (calculi) within the bile duct, concurrently with inflammation of the gallbladder (cholecystitis). The specific type of cholecystitis is not documented, and there is an associated blockage or impedance of bile flow.

Apply this code when documentation clearly indicates choledocholithiasis (bile duct stones) along with cholecystitis, without further specification of the cholecystitis type (e.g., acute or chronic), and evidence of obstruction. This is appropriate when the physician explicitly states "calculus of bile duct with cholecystitis, unspecified, with obstruction."

• Ensure documentation specifies both bile duct calculi and cholecystitis, plus obstruction.
• Do not use if the type of cholecystitis (e.g., acute, chronic) is specified; more specific codes exist.
• Distinguish from codes for cholelithiasis (gallbladder stones) without bile duct involvement.
