ICD-10 Code K80.61 – Calculus of gallbladder and bile duct with cholecystitis, unspecified, with obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.61 – Calculus of gallbladder and bile duct with cholecystitis, unspecified, with obstruction
What it is
This code identifies gallstones in the gallbladder or bile duct with cholecystitis, when the type of cholecystitis is not specified and there is obstruction. Use it for documented stone-related inflammation with blocked bile flow.
Clinical signs
Typical findings include right upper quadrant pain, nausea, vomiting, and signs of gallbladder inflammation. Clinical features vary; refer to documentation for evidence of obstruction and whether the stones involve the gallbladder, bile duct, or both.
When to use this code
Use K80.61 when the record documents calculi plus cholecystitis and also states obstruction, but does not specify the cholecystitis type. It fits encounters where imaging, surgery, or provider assessment confirms gallstone disease with inflammatory change. Check documentation if the site or type is unclear.
Do not use for
Do not use this code if cholecystitis is documented without obstruction, or if the record specifies a different cholecystitis type that maps to another code. Do not assign it when gallstones are absent or obstruction is not stated.
Coding tip
Verify that both cholecystitis and obstruction are documented before selecting K80.61.
