Other diseases of biliary tract (K83) ICD-10-CM
The K83 code range covers other diseases of biliary tract with 11 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- postcholecystectomy syndrome K91.5
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the K83 Code Range
These biliary tract diseases include bile duct conditions, a spasm of the sphincter of Oddi, and cysts.
K83.0 groups cholangitis, with separate entries for primary sclerosing and other forms. Other entries distinguish bile duct obstruction, perforation, and fistula from sphincter of Oddi spasm and biliary cyst. The remaining entries separate other specified diseases from disease left unspecified.
