Obstruction of gallbladder

This code signifies a blockage within the gallbladder itself, preventing the normal flow of bile. This obstruction can arise from various causes other than gallstones, such as strictures, tumors, or external compression. It leads to symptoms like right upper quadrant pain, nausea, and jaundice.

Use this code when documentation clearly indicates an obstruction of the gallbladder without mention of cholelithiasis. This diagnosis is often supported by imaging studies (e.g., ultrasound, CT scan, MRI) showing a blockage within the gallbladder lumen or wall, and clinical findings consistent with biliary obstruction.

• Do not use this code if gallstones are present and causing the obstruction; instead, refer to codes in the K80.- series.
• Ensure documentation specifies the gallbladder is obstructed, not just the bile ducts.
• Look for specific causes of obstruction (e.g., stricture, tumor) as these may require additional, more specific coding.
