K80 MS-DRGs
As the principal diagnosis, all 40 billable codes under K80 group to MS-DRG 444, 445, or 446 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.

About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
Gallstones
Your gallbladder is a pear-shaped organ under your liver. It stores bile, a fluid made by your liver to digest fat. As your stomach and intestines digest food, your gallbladder releases bile through a tube called the common bile duct. The duct connects your gallbladder and liver to your small intestine.
