    ICD-10-CM Code For Other Diseases Of Gallbladder: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K82 includes miscellaneous and other specified diseases of the gallbladder such as bile-containing cysts, perforation, and other specified or unspecified gallbladder disorders that do not fall under cholelithiasis or cholecystitis headings. These ICD-10-CM diagnosis codes are used to document a range of gallbladder conditions, capturing organ-specific pathology, complications, and clinical complexity relevant to biliary disease. Accurate coding within the ICD-10-CM K82 group supports complete clinical documentation and appropriate reimbursement.

    ICD-10-CM K82: Other Diseases Of Gallbladder Overview

    The ICD-10-CM K82 group represents miscellaneous gallbladder disorders not classified elsewhere, including bile-containing cysts, perforation, and other specified or unspecified gallbladder diseases. These conditions affect the hepatobiliary system and can impact biliary drainage, gallbladder function, and abdominal symptomatology. Accurate coding matters for appropriate clinical documentation and reimbursement because it communicates disease specificity and clinical complexity to payers.

    When to Use

    Use a code from this group when documentation indicates a gallbladder condition that is specified as other or unspecified and does not fit into K80 or K81 categories. Select the most specific code based on clinical documentation to reflect complications, laterality if documented, and any associated procedures or findings.

    Typical Clinical Scenarios

    • A middle-aged woman presents to the emergency department with sudden onset right upper quadrant pain, fever, and jaundice after a recent episode of biliary colic. Imaging shows a distended gallbladder with mural thickening but no gallstones visualized; lab tests show cholestatic liver enzyme elevation. A diagnosis from this group is assigned for acute inflammatory gallbladder disease without cholelithiasis. Typical codes: K82.0, K82.3
    • An elderly patient with a history of chronic biliary symptoms reports months of intermittent postprandial right upper quadrant discomfort, nausea, and dyspepsia; ultrasound demonstrates a contracted, thick-walled gallbladder consistent with chronic gallbladder disease without stones. This chronic, non-acute presentation warrants assignment of a chronic gallbladder disorder code from the group to reflect ongoing structural and symptomatic disease. Typical codes: K82.1, K82.4
    • A hospitalized patient recovering from abdominal surgery develops fever and right upper quadrant pain; HIDA scan indicates bile leak or biliary peritonitis as a postoperative complication. In this setting a complication or other specified gallbladder disorder code from the group is used to capture the postoperative biliary complication. Typical codes: K82.2, K82.8, K82.A1
