2026 ICD-10-CM Diagnosis Code K80

Cholelithiasis

ICD-10-CM Code:
K80
ICD-10 Code for:
Cholelithiasis
Is Billable?
Not Valid for Submission
Code Navigator:

K80 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity from the list below for a diagnosis of cholelithiasis. The code is not specific and is NOT valid for the year 2026 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Cholelithiasis

Non-specific codes like K80 require more digits to indicate the appropriate level of specificity. Consider using any of the following billable codes with a higher level of specificity when coding for cholelithiasis:

  • K80.0 for Calculus of gallbladder with acute cholecystitis

  • Use K80.00 for Calculus of gallbladder with acute cholecystitis without obstruction

  • Use K80.01 for Calculus of gallbladder with acute cholecystitis with obstruction

  • K80.1 for Calculus of gallbladder with other cholecystitis

  • Use K80.10 for Calculus of gallbladder with chronic cholecystitis without obstruction

  • K80.2 for Calculus of gallbladder without cholecystitis

  • Use K80.20 for Calculus of gallbladder without cholecystitis without obstruction

  • Use K80.21 for Calculus of gallbladder without cholecystitis with obstruction

Clinical Information

  • 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).

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Patient Education


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.

Your gallbladder is most likely to give you trouble if something blocks the flow of bile through the bile ducts. That is usually a gallstone. Gallstones form when substances in bile harden. Gallstone attacks usually happen after you eat. Signs of a gallstone attack may include nausea, vomiting, or pain in the abdomen, back, or just under the right arm.

Gallstones are most common among older adults, women, overweight people, Native Americans and Mexican Americans.

Gallstones are often found during imaging tests for other health conditions. If you do not have symptoms, you usually do not need treatment. The most common treatment is removal of the gallbladder. Fortunately, you can live without a gallbladder. Bile has other ways to reach your small intestine.
