ICD-10 Code K80.11 – Calculus of gallbladder with chronic cholecystitis with obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.11 – Calculus of gallbladder with chronic cholecystitis with obstruction
What it is
K80.11 identifies gallstones in the gallbladder with long-standing inflammation and blockage. Use it when documentation shows chronic cholecystitis plus obstruction related to the gallbladder calculus.
Clinical signs
Typical findings include recurrent right upper abdominal pain, gallbladder inflammation, and evidence of obstruction. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider clearly documents calculus of the gallbladder with chronic cholecystitis and obstruction. It fits imaging, operative, or pathology reports that support both the chronic inflammatory process and obstructive component. If obstruction is not stated, check documentation.
Do not use for
Do not use K80.11 for gallstones without chronic cholecystitis, or for acute cholecystitis. If the record describes a different site of stone disease or does not confirm obstruction, check documentation.
Coding tip
Confirm that both chronic cholecystitis and obstruction are documented before assigning K80.11.
