ICD-10 Code K83 – Other diseases of biliary tract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K83 – Other diseases of biliary tract
What it is
K83 covers disorders of the biliary tract that are not classified elsewhere. Use it for documented biliary conditions involving the ducts or related structures when a more specific code is not available.
Clinical signs
Clinical features vary; refer to documentation. Findings may include biliary pain, jaundice, cholestatic symptoms, or imaging evidence of ductal abnormality, depending on the specific disorder.
When to use this code
Use K83 when the provider documents a biliary tract disease without a more specific diagnosis in the record. It may apply to nonspecific duct disorders, structural abnormalities, or other biliary conditions that are not separately indexed.
If the chart names a more exact biliary diagnosis, code that condition instead. Review imaging, operative notes, and the final assessment to confirm the documented disorder before assigning K83.
Do not use for
Do not use K83 for gallbladder disease, pancreatic disorders, or liver conditions. If the diagnosis is specified elsewhere in ICD-10-CM, choose the more precise code.
Coding tip
Query the provider when the note says “biliary disease” or “duct disorder” but does not identify the exact condition.
