ICD-10 Code K80.10 – Calculus of gallbladder with chronic cholecystitis without obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.10 – Calculus of gallbladder with chronic cholecystitis without obstruction
What it is
This code identifies gallstones in the gallbladder along with chronic inflammation of the gallbladder, without blockage of the bile duct. Use it when the record clearly supports both the stone and chronic cholecystitis.
Clinical signs
Typical documentation may describe recurrent right upper quadrant pain, biliary colic, or chronic gallbladder inflammation on imaging or pathology. Clinical features vary; refer to documentation.
When to use this code
Use K80.10 when the provider documents gallstones with chronic cholecystitis and does not mention obstruction. It is appropriate for confirmed gallbladder calculus with chronic inflammatory changes, whether found on imaging, surgery, or pathology. Check documentation if the record uses only “cholelithiasis” or does not specify chronic cholecystitis.
Do not use for
Do not use this code when obstruction is documented, because a different ICD-10-CM code applies. Also avoid it if the note only states acute cholecystitis or gallstones without chronic inflammation.
Coding tip
Verify both elements—gallbladder calculus and chronic cholecystitis—and confirm that “without obstruction” is supported by the documentation.
