2026 ICD-10-CM Diagnosis Code K80.20 – Calculus of gallbladder without cholecystitis without obstruction
What it is
This code identifies gallstones located in the gallbladder when there is no cholecystitis and no obstruction. Use it for uncomplicated cholelithiasis documented by the clinician.
Clinical signs
Patients may have no symptoms or may report episodic right upper quadrant pain, nausea, or indigestion. Clinical features vary; refer to documentation.
When to use this code
Use K80.20 when the record clearly states gallbladder stones without inflammation and without blockage of the biliary tract. It also applies when imaging confirms gallstones and the provider documents the condition as uncomplicated. Check documentation if the note mentions cholecystitis, obstruction, or another biliary disorder.
Do not use for
Do not use this code if the chart documents cholecystitis, biliary obstruction, or gallstones in another site. If the record is unclear, check documentation.
Coding tip
Verify that “without cholecystitis” and “without obstruction” are both documented before assigning K80.20.
