Clinical InformationClinical

  • Choledocholithiasis

    presence or formation of gallstones in the common bile duct.

  • Cholelithiasis

    presence or formation of gallstones in the biliary tract, usually in the gallbladder (cholecystolithiasis) or the common bile duct (choledocholithiasis).

Patient EducationClinical

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.

Questions About K80Overview

Is K80 (Cholelithiasis) a billable code?

No. This is a category header that groups the codes for cholelithiasis, and headers cannot be submitted on claims. Claims for cholelithiasis need a more specific code from this category, such as K80.00, K80.01, and K80.10.
