ICD-10 Code K80.6 – Calculus of gallbladder and bile duct with cholecystitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.6 – Calculus of gallbladder and bile duct with cholecystitis
What it is
This code identifies gallstones in the gallbladder or bile duct when cholecystitis is also present. It tells you the patient has both stone disease and inflammation of the gallbladder.
Clinical signs
Typical findings include right upper quadrant pain, tenderness, and signs of gallbladder inflammation. Clinical features vary; refer to documentation, imaging, and the provider’s diagnosis.
When to use this code
Use K80.6 when the record documents calculus of the gallbladder and bile duct with cholecystitis. It fits cases where both the stone-related obstruction and gallbladder inflammation are clearly stated. If the note does not specify the site or type, check documentation before assigning the code.
Do not use for
Do not use this code for gallstones without cholecystitis, or for cholecystitis without documented calculi. Also avoid it when the record only says “biliary disease” or is otherwise nonspecific.
Coding tip
Match the code to the exact wording in the assessment and imaging report, and confirm that cholecystitis is explicitly documented.
