ICD-10 Code K80.80 – Other cholelithiasis without obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.80 – Other cholelithiasis without obstruction
What it is
K80.80 identifies gallstones in the gallbladder or biliary system when no obstruction is documented. Use it for cholelithiasis that is not causing blockage of the bile ducts.
Clinical signs
Clinical features vary; refer to documentation. Patients may have incidental gallstones or biliary-type discomfort, but the record should not describe duct obstruction or related complications.
When to use this code
Use this code when the provider documents cholelithiasis and specifically states there is no obstruction. It also fits cases where imaging shows gallstones, but the note does not support obstruction or another more specific gallstone code. Check documentation if the anatomy or complication status is unclear.
Do not use for
Do not use K80.80 if the record documents obstruction, cholecystitis, or choledocholithiasis with duct involvement. Also avoid it when the note identifies a more specific gallstone diagnosis.
Coding tip
Code only what the provider documents, and confirm that “without obstruction” is clearly supported in the chart.
