2022 ICD-10-CM Code C78.7

Secondary malignant neoplasm of liver and intrahepatic bile duct

Version 2021

Valid for Submission

ICD-10:C78.7
Short Description:Secondary malig neoplasm of liver and intrahepatic bile duct
Long Description:Secondary malignant neoplasm of liver and intrahepatic bile duct

Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of ill-defined, other secondary and unspecified sites (C76-C80)
      • Secondary malignant neoplasm of resp and digestive organs (C78)

C78.7 is a billable diagnosis code used to specify a medical diagnosis of secondary malignant neoplasm of liver and intrahepatic bile duct. The code C78.7 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 C78.7 might also be used to specify conditions or terms like adenocarcinoma of liver, extrahepatic bile ducts tnm finding, gallbladder tnm finding, lymphoma finding, lymphoma involves liver , metastasis to liver from adenocarcinoma, etc.

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

Approximate Synonyms

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

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code C78.7 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The code C78.7 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


Liver Cancer

Your liver is the largest organ inside your body. It helps your body digest food, store energy, and remove poisons. Primary liver cancer starts in the liver. Metastatic liver cancer starts somewhere else and spreads to your liver.

Risk factors for primary liver cancer include

Symptoms can include a lump or pain on the right side of your abdomen and yellowing of the skin. However, you may not have symptoms until the cancer is advanced. This makes it harder to treat. Doctors use tests that examine the liver and the blood to diagnose liver cancer. Treatment options include surgery, radiation, chemotherapy, or liver transplantation.
