Calculus of GB and bile duct w chronic cholecyst w obst

This code signifies the presence of gallstones in both the gallbladder and the bile ducts, accompanied by long-standing inflammation of the gallbladder and an obstruction of the bile flow. This condition often leads to persistent abdominal pain, jaundice, and digestive issues.

Use this code when documentation clearly indicates cholelithiasis (gallstones) in both the gallbladder and the common bile duct, along with a diagnosis of chronic cholecystitis and evidence of biliary obstruction. This is typically supported by imaging studies (e.g., ultrasound, MRI, ERCP) and clinical findings.

• Ensure documentation specifies both gallbladder and bile duct calculi.
• Verify the cholecystitis is explicitly documented as "chronic," not acute.
• Confirm the presence and nature of the obstruction (e.g., partial, complete) is noted.
