ICD-10 Code K80.19 – Calculus of gallbladder with other cholecystitis with obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.19 – Calculus of gallbladder with other cholecystitis with obstruction
What it is
This code identifies gallstones in the gallbladder when they are associated with cholecystitis and there is obstruction. Use it when the record shows both inflammation and blockage related to the gallbladder stone.
Clinical signs
Typical findings include right upper abdominal pain, tenderness, and signs of gallbladder inflammation. Clinical features vary; refer to documentation for evidence of obstruction and the type of cholecystitis.
When to use this code
Use K80.19 when the provider documents gallstones in the gallbladder with cholecystitis and obstruction, but does not specify acute or chronic cholecystitis. It is appropriate when the note clearly links the stone to the inflammatory and obstructive process. Check documentation if the type of cholecystitis is unclear.
Do not use for
Do not use this code if the record does not mention obstruction or if cholecystitis is not documented. Do not assign it when a more specific gallstone code is supported by the chart.
Coding tip
Confirm that both obstruction and cholecystitis are documented before coding K80.19.
