ICD-10 Code K80.3 – Calculus of bile duct with cholangitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.3 – Calculus of bile duct with cholangitis
What it is
K80.3 identifies a bile duct stone with associated cholangitis. Use it when documentation shows choledocholithiasis and inflammation or infection of the biliary tree.
Clinical signs
Clinical features vary; refer to documentation. Common findings include right upper quadrant pain, fever, jaundice, and evidence of biliary obstruction or infection on imaging or exam.
When to use this code
Use K80.3 when the record clearly links a calculus in the bile duct with cholangitis. It may be supported by provider assessment, imaging, or operative findings that document both conditions. If the note only states a bile duct stone or only cholangitis, check documentation before assigning this code.
Do not use for
Do not use this code for gallbladder stones without bile duct involvement, or for cholangitis without a documented calculus. Check documentation if the site of the stone or the presence of infection is unclear.
Coding tip
Code K80.3 only when both the stone and cholangitis are documented together; otherwise, query the provider.
