Cholelithiasis (K80) ICD-10-CM

About the K80 Code Range

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.
