ICD-10 Code K80.34 – Calculus of bile duct with chronic cholangitis without obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.34 – Calculus of bile duct with chronic cholangitis without obstruction
What it is
K80.34 identifies a bile duct stone with chronic inflammation of the bile ducts, and no obstruction is documented. Use it when the record clearly links the calculus and chronic cholangitis.
Clinical signs
Clinical features vary; refer to documentation. Records may note recurrent cholangitis, biliary pain, jaundice, or imaging evidence of bile duct calculi with chronic duct inflammation.
When to use this code
Use this code when the provider documents a bile duct calculus and chronic cholangitis, and specifically states there is no obstruction. It fits encounters where the diagnosis is confirmed by imaging, operative findings, or specialist assessment. If obstruction is not addressed, check documentation before coding.
Do not use for
Do not use it if the stone is in the gallbladder rather than the bile duct. Also avoid it when obstruction is documented or when chronic cholangitis is not clearly linked to the calculus.
Coding tip
Match the code to the exact anatomic site and obstruction status in the note.
