Calculus of GB w acute and chronic cholecyst w/o obstruction

This code signifies the presence of gallstones within the gallbladder, accompanied by both acute and chronic inflammation of the gallbladder wall. Importantly, there is no blockage of the bile ducts associated with this condition. Patients typically experience recurrent episodes of right upper quadrant pain, often exacerbated by fatty meals, along with more persistent, milder symptoms.

Apply this code when documentation clearly indicates cholelithiasis coexisting with both acute and chronic cholecystitis, and specifically states the absence of obstruction. This diagnosis is often supported by imaging studies (e.g., ultrasound, CT scan) showing gallstones and gallbladder wall thickening, along with clinical findings of inflammation.

• Ensure documentation explicitly states both acute and chronic cholecystitis. If only one is mentioned, a different code may be appropriate.
• Verify the absence of obstruction. If obstruction is present, a code from K80.3-K80.5 would be more accurate.
• Do not use this code if the cholecystitis is specified as gangrenous, emphysematous, or with perforation, as those have more specific codes.
