About K82.A
K82.A is the ICD-10-CM diagnosis code for disorders of gallbladder in diseases classified elsewhere. It belongs to category K82 (other diseases of gallbladder), block K80-K87 (disorders of gallbladder, biliary tract and pancreas) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Related codes cover obstruction of gallbladder (K82.0), hydrops of gallbladder (K82.1), perforation of gallbladder (K82.2), fistula of gallbladder (K82.3), Cholesterolosis of gallbladder (K82.4), other specified diseases of gallbladder (K82.8) and disease of gallbladder, unspecified (K82.9).
To report this condition, pick the subcode that matches the documentation: K82.A1 (cholecystitis) and K82.A2 (cholecystitis).
