K80 is a non-billable ICD-10-CM category code for cholelithiasis, so it cannot be submitted on claims. Use a more specific code from this category instead, such as K80.00, K80.01, K80.10, and K80.11.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to K80: its own notes plus those printed at Chapter 11. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • retained cholelithiasis following cholecystectomy (K91.86)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 11 (K00-K95) Diseases of the digestive system applies to 863 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Clinical InformationClinical

  • 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

What is the ICD-10 code for cholelithiasis?

K80 is the ICD-10-CM category for cholelithiasis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

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.

Can K80 be reported with K91.86?

Not as a rule. The Excludes1 note on K80 lists "retained cholelithiasis following cholecystectomy (K91.86)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
