ICD-10 Code K80.32 – Calculus of bile duct with acute cholangitis without obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.32 – Calculus of bile duct with acute cholangitis without obstruction
What it is
K80.32 identifies a bile duct stone associated with acute cholangitis, without documented obstruction. Use it when the record clearly links choledocholithiasis to an acute biliary infection and does not state obstruction.
Clinical signs
Typical findings include right upper quadrant pain, fever, jaundice, and evidence of biliary infection. Clinical features vary; refer to documentation for the confirmed diagnosis and whether obstruction is present.
When to use this code
Use this code when the provider documents a calculus in the bile duct and acute cholangitis, and specifically notes no obstruction. It also fits when the note states cholangitis due to a bile duct stone without obstruction. Check documentation if the record mentions obstruction, because that changes code selection.
Do not use for
Do not use K80.32 if the chart documents obstruction, since that requires a different code. Also avoid it when cholangitis is absent or the stone is only in the gallbladder.
Coding tip
Verify both the stone location and the presence or absence of obstruction before assigning the code.
