Calculus of gallbladder w oth cholecystitis with obstruction

This code signifies the presence of gallstones (calculi) within the gallbladder, accompanied by inflammation of the gallbladder (cholecystitis) due to causes other than acute or chronic cholecystitis, and with a blockage of the bile flow. This obstruction is typically caused by the gallstones themselves.

Use this code when documentation clearly indicates gallstones in the gallbladder, cholecystitis specified as "other" (e.g., emphysematous, gangrenous, or xanthogranulomatous cholecystitis), and evidence of biliary obstruction. This often presents with symptoms like severe right upper quadrant pain, fever, and jaundice.

• Ensure the documentation specifies "other cholecystitis" and not just acute or chronic, which have separate codes.
• Verify that obstruction is explicitly documented as present, as codes exist for calculus with cholecystitis without obstruction.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter.
