Calculus of gallbladder w chronic cholecyst w/o obstruction

This code signifies the presence of gallstones within the gallbladder, accompanied by persistent inflammation of the gallbladder wall. Crucially, there is no indication of a blockage of the bile ducts caused by these stones. This represents a chronic inflammatory process rather than an acute obstruction.

Use this code when documentation clearly indicates cholelithiasis (gallstones) and chronic cholecystitis, with specific absence of obstruction. This is appropriate for patients experiencing recurrent right upper quadrant pain, dyspepsia, or other symptoms consistent with chronic gallbladder inflammation, where imaging confirms gallstones and no obstructive pathology.

• Ensure documentation explicitly states "chronic" cholecystitis and "without obstruction."
• Do not use this code if acute cholecystitis is present; refer to codes in the K80.0- or K81.0- series.
• If obstruction is noted, even with chronic inflammation, a different code from the K80.1- series specifying obstruction should be selected.
