ICD Code K81.2

ICD code K81.2 is acute cholecystitis with chronic cholecystitis, meaning the patient has both a sudden, severe inflammation and a long-standing inflammation of the gallbladder at the same time.

1. Presence of right upper quadrant abdominal pain, often severe and persistent

2. Clinical or imaging evidence of gallbladder inflammation (e.g., gallbladder wall thickening, pericholecystic fluid)

3. Symptoms or history indicating acute onset (e.g., fever, leukocytosis, Murphy’s sign)

4. Documentation or imaging findings of chronic gallbladder changes (e.g., fibrosis, thickened gallbladder wall, history of recurrent episodes)

5. Exclusion of gallbladder perforation, gangrene, or abscess formation

6. No evidence of calculous obstruction causing only chronic symptoms without acute exacerbation
