ICD-10 Code K82.3 – Fistula of gallbladder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K82.3 – Fistula of gallbladder
What it is
K82.3 identifies an abnormal passage connecting the gallbladder to another organ or structure. It is used when documentation specifically states a gallbladder fistula.
Clinical signs
Clinical features vary; refer to documentation. Findings may include imaging or operative evidence of an abnormal gallbladder communication, often in the setting of chronic gallbladder disease.
When to use this code
Use K82.3 when the provider documents a fistula involving the gallbladder, such as a cholecystoenteric or other gallbladder fistula. Code it when the diagnosis is confirmed by imaging, surgery, or clear specialist documentation. Check documentation if the record only suggests a complication without confirmation.
Do not use for
Do not use this code for gallstones, cholecystitis, or biliary obstruction without a documented fistula. If the note describes a suspected communication only, check documentation before assigning K82.3.
Coding tip
Assign K82.3 only when the fistula is explicitly documented; otherwise, query the provider for clarification.
