ICD-10 Code K80 – Cholelithiasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80 – Cholelithiasis
What it is
K80 identifies cholelithiasis, meaning gallstones are present in the gallbladder or biliary tract. Use it when the record documents stones, with or without symptoms.
Clinical signs
Clinical features vary; refer to documentation. Common findings include right upper quadrant pain, nausea, or incidental imaging evidence of gallstones, and the chart may specify obstruction or inflammation.
When to use this code
Use K80 when the provider documents gallstones as the diagnosis, including asymptomatic or symptomatic cases. Code selection may depend on whether there is obstruction, cholecystitis, or other specified complications. Check documentation for the exact type and site.
Do not use for
Do not use K80 for biliary colic without documented stones, or for gallbladder disease that is not confirmed as cholelithiasis. If the record is unclear, check documentation before assigning the code.
Coding tip
Review the note for obstruction and cholecystitis details, because those specifics drive the correct K80 subcategory.
