About K85.8
K85.8 is the ICD-10-CM diagnosis code for other acute pancreatitis. It belongs to category K85 (acute pancreatitis), 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 3 subcodes must be used instead.
Within K85, choose K85.8 (Other acute pancreatitis) only when documentation doesn't support a more specific option: idiopathic acute pancreatitis (K85.0), biliary acute pancreatitis (K85.1), alcohol induced acute pancreatitis (K85.2), drug induced acute pancreatitis (K85.3) and unspecified (K85.9).
To report this condition, pick the subcode that matches the documentation: K85.80 (without necrosis or infection), K85.81 (with uninfected necrosis) and K85.82 (with infected necrosis).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (expanded into subcodes).
