Cholelithiasis (K80) ICD-10-CM
The K80 code range covers cholelithiasis with 50 ICD-10-CM diagnosis codes. 40 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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the K80 range.
Cholelithiasis
Presence or formation of GALLSTONES in the BILIARY TRACT, usually in the gallbladder (CHOLECYSTOLITHIASIS) or the common bile duct (CHOLEDOCHOLITHIASIS).
About the K80 Code Range
Gallstones can form in the gallbladder or bile ducts. These codes distinguish where the stones are, whether inflammation is present, and whether there is an obstruction.
Gallbladder stones appear with acute cholecystitis (gallbladder inflammation) in K80.0, with other forms of cholecystitis in K80.1, or without it in K80.2. Bile duct stones appear with cholangitis (bile duct inflammation) in K80.3, with cholecystitis in K80.4, or with neither in K80.5.
K80.6 and K80.7 distinguish stones in both locations by whether cholecystitis is present. Further subdivisions distinguish acute, chronic, or both forms of inflammation where specified, and obstruction from no obstruction.
