What ICD-10 codes are used for liver metastases?

Liver metastases refer to cancerous tumors that have spread to the liver from another part of the body. These metastases are not the same as primary liver cancers originating in the liver. The ICD-10-CM system offers specific codes for secondary liver tumors or metastases.

The primary ICD-10-CM code for liver metastases is C78.7: Secondary malignant neoplasm of liver and intrahepatic bile duct. This code describes tumors metastasizing to the liver from other primary cancer sites.

Clinical information

Liver metastases are more common than primary liver cancer and often originate from colorectal, breast, lung, pancreas, and stomach cancers.
The presence of liver mets usually indicates advanced-stage cancer.
Symptoms might include jaundice, abdominal pain, unexplained weight loss, fatigue, and loss of appetite.
Imaging tests like CT, MRI, and ultrasound are often used for detection.
Management options include surgery, chemotherapy, radiation, targeted therapy, and other advanced interventional techniques.
The prognosis largely depends on the primary cancer type, the extent of liver involvement, and the patient's overall health.
