Obstruction of gallbladder

This diagnosis code signifies a blockage within the gallbladder, preventing the normal flow of bile. This obstruction can be caused by gallstones, tumors, strictures, or other masses, leading to symptoms such as right upper quadrant pain, nausea, and jaundice.

Apply this code when documentation clearly indicates an obstruction of the gallbladder lumen. This is typically supported by imaging studies (e.g., ultrasound, CT, MRI) demonstrating a blockage and clinical findings consistent with biliary obstruction.

• Differentiate from cholelithiasis without obstruction, which has a separate code.
• Always look for the underlying cause of the obstruction (e.g., calculus, tumor) and code it as a primary or secondary diagnosis as appropriate.
• Ensure documentation specifies "obstruction" rather than just inflammation or stones.
