Cholelithiasis (K80)

The ICD-10 codes K80 through K80.81 are used to classify various forms of cholelithiasis, a condition characterized by gallstones affecting the gallbladder and bile ducts. This coding group covers cholelithiasis with different types of inflammation such as acute, chronic, or combined cholecystitis and cholangitis, as well as instances with or without obstruction.

The ICD-10 code for cholelithiasis helps medical professionals and coders identify specific presentations including gallbladder stones with acute or chronic cholecystitis (e.g., codes K80.00 for acute cholecystitis without obstruction and K80.01 with obstruction). It also includes conditions like gallstones causing bile duct cholangitis (e.g., K80.30 series), and cases where gallstones exist without inflammation (e.g., K80.20). Several codes detail the presence or absence of obstruction, important for treatment planning. Synonyms such as "gallbladder calculus," "cholecystolithiasis," "biliary colic," and "common bile duct calculus" correspond directly to these codes, guiding diagnosis and documentation. These codes also cover complications like obstruction of the gallbladder or bile ducts caused by stones, helping accurately capture biliary tract disease variations.

Instructional Notations

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

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Choledocholithiasis

Presence or formation of GALLSTONES in the COMMON BILE DUCT.

Cholelithiasis

Presence or formation of GALLSTONES in the BILIARY TRACT, usually in the gallbladder (CHOLECYSTOLITHIASIS) or the common bile duct (CHOLEDOCHOLITHIASIS).
