About the K80–K87 Code Range
Gallstones, inflammation, and other disorders can affect the gallbladder, bile ducts, or pancreas. The categories separate these conditions by the organ involved and the type of disorder.
K80 describes gallstones, also called cholelithiasis. Its subdivisions distinguish stones in the gallbladder, bile duct, or both, and whether inflammation is present. K81 describes cholecystitis, or gallbladder inflammation, and distinguishes acute from chronic inflammation. K82 groups other gallbladder diseases, while K83 groups other bile duct disorders.
K85 describes acute pancreatitis, or sudden inflammation of the pancreas, with subdivisions based on its cause. K86 includes chronic pancreatitis, pancreatic cysts, and other pancreatic diseases. K87 groups disorders of these organs in diseases classified elsewhere.
Questions About This Page
How many codes are in the K80-K87 range?
The K80-K87 range contains 112 ICD-10-CM diagnosis codes in FY 2027. 88 of them are billable, and the rest are category headers that organize the section.
What conditions does K80-K87 cover?
The range covers disorders of gallbladder, biliary tract and pancreas. The code ranges listed above break it into groups of related conditions, and each one links to its own page with the full code list.
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.

The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

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.

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
