ICD-10 Code K80.41 – Calculus of bile duct with cholecystitis, unspecified, with obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.41 – Calculus of bile duct with cholecystitis, unspecified, with obstruction
What it is
K80.41 identifies a gallstone in the bile duct with cholecystitis, but the type of cholecystitis is not specified. The record also documents obstruction, meaning bile flow is blocked.
Clinical signs
Typical findings include right upper quadrant pain, fever, and tenderness, with signs of biliary obstruction. Clinical features vary; refer to documentation for imaging, operative, or provider-confirmed evidence.
When to use this code
Use this code when the provider documents a bile duct calculus with cholecystitis and obstruction, but does not specify the cholecystitis type. It fits confirmed gallstone disease affecting both the duct and gallbladder. Check documentation if obstruction is implied but not clearly stated.
Do not use for
Do not use this code if the record only shows cholelithiasis without cholecystitis or without obstruction. Also avoid it when the cholecystitis type is documented differently and a more specific code applies.
Coding tip
Verify that both cholecystitis and obstruction are documented; if either element is missing, select a different gallstone code.
