ICD-10 Code K82.8 – Other specified diseases of gallbladder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K82.8 – Other specified diseases of gallbladder
What it is
K82.8 identifies gallbladder disorders that are specified in the record but do not fit a more exact ICD-10-CM gallbladder code. Use it only when the documentation names a distinct gallbladder condition that lacks a dedicated code.
Clinical signs
Clinical features vary; refer to documentation. Patients may have right upper quadrant pain, nausea, or imaging findings suggesting gallbladder disease, but the exact diagnosis must be stated in the chart.
When to use this code
Use K82.8 when the provider documents a specific, non-indexed gallbladder disorder and no more specific code is available. It may apply after imaging, operative findings, or specialist assessment. If the note only says “gallbladder disease” or is vague, check documentation first.
Do not use for
Do not use this code for cholelithiasis, acute cholecystitis, or other conditions with their own ICD-10-CM codes. It is also inappropriate when the diagnosis is nonspecific or uncertain.
Coding tip
Match the code to the exact documented gallbladder diagnosis and confirm that no more specific code exists before assigning K82.8.
