K80.8Other cholelithiasis

K80.8 is the ICD-10-CM diagnosis code for other cholelithiasis. It belongs to category K80 (cholelithiasis), 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.

Within K80, choose K80.8 (Other cholelithiasis) only when documentation doesn't support a more specific option: calculus of gallbladder with acute cholecystitis (K80.0), calculus of gallbladder with other cholecystitis (K80.1), calculus of gallbladder without cholecystitis (K80.2), calculus of bile duct with cholangitis (K80.3), calculus of bile duct with cholecystitis (K80.4), calculus of bile duct without cholangitis or cholecystitis (K80.5), calculus of gallbladder and bile duct with cholecystitis (K80.6) and calculus of gallbladder and bile duct without cholecystitis (K80.7).

To report this condition, pick the subcode that matches the documentation: K80.80 (without obstruction) and K80.81 (with obstruction).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
