    ICD-10-CM Code For Cholelithiasis: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K80 includes diagnoses for gallstone disease, including gallstones in the gallbladder, bile duct stones, and gallstone-associated inflammation or obstruction. These ICD-10-CM diagnosis codes are used to document clinical presentations such as symptomatic cholelithiasis, choledocholithiasis, and cholecystitis, capturing disease severity and biliary tract involvement. Accurate coding within the ICD-10-CM K80 group supports proper claim adjudication through complete clinical documentation and appropriate reimbursement.

    ICD-10-CM K80: Cholelithiasis Overview

    The ICD-10-CM K80 code group represents cholelithiasis, commonly known as gallstones, and related disorders of the gallbladder and biliary tract. These diagnoses target the hepatobiliary system, including obstructive and nonobstructive gallstone disease and associated inflammation. Accurate coding is important for reflecting clinical complexity and supporting appropriate reimbursement through complete documentation.

    When to Use

    Use a code from this group when documentation indicates the presence of gallstones, whether asymptomatic, symptomatic, or complicated by cholecystitis or biliary obstruction. Select codes that reflect the anatomic site and whether the condition is obstructive, nonobstructive, or associated with infection to ensure accurate clinical and billing records.

    Typical Clinical Scenarios

    • A middle-aged woman presents to the emergency department with sudden onset right upper quadrant abdominal pain, fever, nausea, and elevated white blood cell count after a fatty meal. Ultrasound shows multiple gallstones with an obstructing stone in the cystic duct and sonographic Murphy sign, consistent with acute cholecystitis due to gallstones; a diagnosis from this group is assigned to capture gallstone-related acute inflammation. Typical codes: K80.00, K80.10
    • An older adult with known chronic gallbladder disease reports intermittent postprandial biliary colic over months and undergoes outpatient evaluation; ultrasound demonstrates cholelithiasis without signs of acute inflammation or obstruction. This represents chronic, symptomatic gallstone disease managed electively and coded to indicate presence of gallstones without acute cholecystitis or cholangitis. Typical codes: K80.20, K80.30
    • A patient is admitted with ascending cholangitis and sepsis after a retained common bile duct stone is identified on imaging; ERCP is planned for stone extraction and decompression. Because the primary problem is biliary tract obstruction with infected bile due to gallstones, a code from this group specifying gallstone obstruction of the bile duct with cholangitis or sepsis is assigned. Typical codes: K80.10, K80.11
