Disorders of gallbladder, biliary tract and pancreas in diseases classified elsewhere
In Disorders of gallbladder, biliary tract and pancreas (K80-K87), chapter 11: Diseases of the Digestive System
- K87 is billable and valid on claims for FY 2027. If the record has more detail, check the other codes under K80-K87 below.
- As a secondary diagnosis it is not a CC or MCC, so it doesn't raise the MS-DRG payment.
- Doesn't count toward a Medicare Advantage risk score (no HCC in V28).
- AHRQ's Chronic Condition Indicator classes it as not chronic (an acute or short-term condition).
- Can't be the principal diagnosis: code the underlying condition first. (Manifestation list)

About the condition

Bile Duct Diseases
Your liver makes a digestive juice called bile. Your gallbladder stores it between meals. When you eat, your gallbladder pushes the bile into tubes called bile ducts. They carry the bile to your small intestine. The bile helps break down fat. It also helps the liver get rid of toxins and wastes.

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.
