Calculus of GB and bile duct w chronic cholecyst w/o obst

This code signifies the presence of gallstones within both the gallbladder and the common bile duct, accompanied by persistent inflammation of the gallbladder. Crucially, there is no blockage of the bile flow associated with these stones.

Use this code when diagnostic imaging (e.g., ultrasound, MRI) confirms cholelithiasis and choledocholithiasis, and pathology reports or clinical notes indicate chronic cholecystitis without evidence of obstruction. This applies to patients presenting with recurrent right upper quadrant pain, dyspepsia, or other symptoms consistent with chronic gallbladder inflammation and documented stones in both locations.

• Ensure documentation explicitly states "without obstruction" to differentiate from codes indicating obstruction.
• Do not use this code if acute cholecystitis is present; a different code would be more appropriate.
• Verify the presence of stones in both the gallbladder and bile duct; if only one location, a more specific code is needed.
