2022 ICD-10-CM Code C24.0

Malignant neoplasm of extrahepatic bile duct

Version 2021

Valid for Submission

ICD-10:C24.0
Short Description:Malignant neoplasm of extrahepatic bile duct
Long Description:Malignant neoplasm of extrahepatic bile duct

Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of digestive organs (C15-C26)
      • Malignant neoplasm of other and unsp 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 C24.0 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code C24.0 might also be used to specify conditions or terms like carcinoma common bile duct, carcinoma of extrahepatic bile duct, cholangiocarcinoma of biliary tract, extrahepatic bile ducts tnm finding, extrahepatic bile ducts tnm finding , extrahepatic bile ducts tnm finding, etc.

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

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code C24.0:


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.

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code C24.0 are found in the index:

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Table of Neoplasms

The code C24.0 is included 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.

Information for Patients


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

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.
