About K83.0
K83.0 is the ICD-10-CM diagnosis code for cholangitis. It belongs to category K83 (other diseases of biliary tract), 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 K83 (other diseases of biliary tract), K83.0 is specifically for cholangitis. Related codes cover obstruction of bile duct (K83.1), perforation of bile duct (K83.2), fistula of bile duct (K83.3), spasm of sphincter of Oddi (K83.4), biliary cyst (K83.5), other specified diseases of biliary tract (K83.8) and disease of biliary tract, unspecified (K83.9).
To report this condition, pick the subcode that matches the documentation: K83.01 (cholangitis) and K83.09 (cholangitis).
Don't report K83.0 together with the conditions in its Excludes1 note: cholangitic liver abscess (K75.0) and cholangitis with choledocholithiasis (K80.3-, K80.4-).
The conditions in its Excludes2 note aren't part of K83.0, but may be coded alongside it if the patient has both: chronic nonsuppurative destructive cholangitis (K74.3), primary biliary cholangitis (K74.3) and primary biliary cirrhosis (K74.3).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2019 (expanded into subcodes).
Before ICD-10, this condition was coded in ICD-9-CM as 576.1 (cholangitis).
