Code Classification

  • Neoplasms
    (C00–D49)
    • Malignant neoplasms of digestive organs
      (C15-C26)
      • Malignant neoplasm of other and unspecified parts of biliary tract
        (C24)

C24.0 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of extrahepatic bile duct. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic bile or biliary (tract) duct or passage (common) (cystic) (extrahepatic) ; Neoplasm, neoplastic choledochal duct ; Neoplasm, neoplastic common (bile) duct ; Neoplasm, neoplastic cystic (bile) duct (common) ; Neoplasm, neoplastic extrahepatic (bile) duct ; Neoplasm, neoplastic gall duct (extrahepatic) ; Neoplasm, neoplastic hepatic [See Also: Index to disease, by histology] duct (bile) ; etc

Clinical Classification

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.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Malignant neoplasm of biliary duct or passage NOS
  • Malignant neoplasm of common bile duct
  • Malignant neoplasm of cystic duct
  • Malignant neoplasm of hepatic duct

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Table of Neoplasms

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Patient Education


Bile Duct Cancer

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.

Bile duct cancer is rare. It can happen in the parts of the bile ducts that are outside or inside the liver. Cancer of the bile duct outside of the liver is much more common. Risk factors include having inflammation of the bile duct, ulcerative colitis, and some liver diseases.

Symptoms can include:

  • Jaundice
  • Itchy skin
  • Fever
  • Abdominal pain

Tests to diagnose bile duct cancer may include a physical exam, imaging tests of the liver and bile ducts, blood tests, and a biopsy.

Treatments include surgery, radiation therapy, and chemotherapy.
