ICD-10 Code K80.5 – Calculus of bile duct without cholangitis or cholecystitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.5 – Calculus of bile duct without cholangitis or cholecystitis
What it is
This code identifies a stone in the bile duct when there is no documented cholangitis or cholecystitis. Use it for choledocholithiasis or related bile duct calculus cases without those inflammatory complications.
Clinical signs
Patients may have biliary colic, jaundice, dark urine, pale stools, or abnormal liver tests. Clinical features vary; refer to documentation for evidence of bile duct obstruction without infection or gallbladder inflammation.
When to use this code
Use K80.5 when the record clearly states a bile duct stone and does not document cholangitis or cholecystitis. It also fits cases where imaging, surgery, or endoscopy confirms a ductal calculus and the provider excludes inflammatory complications.
Do not use for
Do not use this code if cholangitis or cholecystitis is documented. Check documentation if the note only says gallstones, gallbladder stone, or unspecified biliary obstruction.
Coding tip
Verify the provider’s wording and code any documented inflammatory condition separately when supported.
