ICD-10 Code K80.30 – Calculus of bile duct with cholangitis, unspecified, without obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.30 – Calculus of bile duct with cholangitis, unspecified, without obstruction
What it is
This code identifies a stone in the bile duct with cholangitis, but the documentation does not specify the stone type and no obstruction is documented. Use it when the record clearly supports both choledocholithiasis and cholangitis.
Clinical signs
Typical findings include right upper abdominal pain, fever, jaundice, or other signs of biliary infection. Clinical features vary; refer to documentation, and confirm that cholangitis is documented rather than isolated bile duct stone disease.
When to use this code
Use K80.30 when the provider documents a bile duct calculus with cholangitis and does not specify the calculus as impacted, obstructing, or another subtype. You should also use it when the note states no obstruction. If the record is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for gallbladder stones without bile duct involvement, or for bile duct stones with obstruction or impaction. Do not assign it if cholangitis is not documented.
Coding tip
Verify both elements—bile duct calculus and cholangitis—before coding, and match the absence of obstruction exactly as documented.
