ICD-10 Code K82 – Other diseases of gallbladder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K82 – Other diseases of gallbladder
What it is
K82 is used for gallbladder disorders that are not classified elsewhere. It covers conditions affecting the gallbladder when the record does not support a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Gallbladder disorders may present with right upper quadrant pain, nausea, or findings noted on imaging, but you should code only what is documented.
When to use this code
Use K82 when the provider documents a gallbladder disease that does not fit a more specific ICD-10 code. It is appropriate when the chart states an unspecified or other gallbladder disorder and no alternate diagnosis is confirmed.
Review the note for a named condition such as cholelithiasis, cholecystitis, or a congenital anomaly before assigning K82. If the documentation is vague, check documentation rather than assuming a specific gallbladder disease.
Do not use for
Do not use K82 for gallstones, acute or chronic cholecystitis, or other separately coded gallbladder conditions. Those diagnoses have their own ICD-10-CM codes.
Coding tip
Match K82 only to the exact wording in the provider record and confirm that no more specific gallbladder code applies.
