ICD-10 Code K80.62 – Calculus of gallbladder and bile duct with acute cholecystitis without obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.62 – Calculus of gallbladder and bile duct with acute cholecystitis without obstruction
What it is
This code identifies gallstones in the gallbladder or bile duct when the patient also has acute cholecystitis, and there is no documented obstruction. Use it when the record clearly links the stone disease with acute gallbladder inflammation.
Clinical signs
Typical findings include right upper quadrant pain, tenderness, nausea, vomiting, and signs of acute gallbladder inflammation. Imaging may show gallstones and cholecystitis; clinical features vary, so refer to documentation.
When to use this code
Use K80.62 when the provider documents calculus of the gallbladder or bile duct with acute cholecystitis and specifically states no obstruction. It may also apply when the encounter is for evaluation or management of this confirmed condition. Check documentation if the record does not clearly distinguish obstruction status.
Do not use for
Do not use this code if acute cholecystitis is absent, if obstruction is documented, or if the stone is only suspected. Check documentation when the note describes biliary colic or chronic gallbladder disease instead.
Coding tip
Verify both the calculus location and the acute cholecystitis diagnosis, then confirm that obstruction is explicitly ruled out in the record.
