Code Classification
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:
- Adenocarcinoma of liver
- Extrahepatic bile ducts TNM finding
- Gallbladder TNM finding
- Lymphoma finding
- Lymphoma involves liver
- Metastasis to liver from adenocarcinoma
- Metastasis to liver of unknown primary
- pT3 and/or N1
- pT3: Tumor invades the liver, gallbladder, pancreas, and/or ipsilateral branches of the portal vein
- pT3: Tumor perforates the serosa
- Secondary malignant neoplasm of biliary tract
- Secondary malignant neoplasm of intrahepatic bile ducts
- Secondary malignant neoplasm of liver
- Secondary squamous cell carcinoma of liver
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code C78.7 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 435 | MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITH MCC | 07 | 1.7528 |
| 436 | MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITH CC | 07 | 1.1202 |
| 437 | MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITHOUT CC/MCC | 07 | 0.8945 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert C78.7 to ICD-9 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
- Having hepatitis B or C
- Heavy alcohol use
- Having cirrhosis, or scarring of the liver
- Having hemochromatosis, an iron storage disease
- Obesity and diabetes
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.
