ICD-10 Code K80.8 – Other cholelithiasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.8 – Other cholelithiasis
What it is
K80.8 identifies gallstones in the gallbladder or biliary system when the record does not fit a more specific cholelithiasis code. Use it when documentation clearly says “other cholelithiasis” or gives an equivalent unspecified variant.
Clinical signs
Clinical features vary; refer to documentation. Patients may have biliary colic, right upper quadrant pain, nausea, or incidental imaging findings of gallstones without acute infection or obstruction.
When to use this code
Use K80.8 when the provider documents cholelithiasis as “other” or describes a gallstone condition that is not captured by a more specific ICD-10 option. It is appropriate when the record supports gallstones but does not specify acute cholecystitis, obstruction, or another listed subtype. Check documentation if the note is vague.
Do not use for
Do not use this code for acute cholecystitis, choledocholithiasis, or gallstone obstruction when those conditions are documented. If the record names a more specific gallstone diagnosis, code that instead.
Coding tip
Match the code to the exact documented gallstone diagnosis and avoid defaulting to K80.8 when a more specific option is available.
