Clinical Information
  • (hep-a-toe-blas-toe-ma) a type of liver tumor that occurs in infants and children.
  • (hep-a-toe-ma) a liver tumor.
  • (hep-a-toe-sel-yoo-ler kar-sin-o-ma) a type of adenocarcinoma, the most common type of liver tumor.
  • A malignant liver neoplasm that occurs almost exclusively in infants, although isolated cases in older children and adults have been reported. Grossly, hepatoblastoma is solid, well circumscribed, and more often solitary than multiple. Microscopically, most of the tumors are composed exclusively of immature hepatocytic elements. About a fourth of hepatoblastomas contain a stromal component that may be undifferentiated or develop into bone or cartilage. The treatment of choice for hepatoblastoma is surgical excision with adjuvant therapy. Liver transplantation is being increasingly used as well.
  • A malignant tumor that arises from hepatocytes. Hepatocellular carcinoma is relatively rare in the United States but very common in all african countries south of the sahara and in southeast asia. Most cases are seen in patients over the age of 50 years, but this tumor can also occur in younger individuals and even in children. Hepatocellular carcinoma is more common in males than females and is associated with hepatitis b, hepatitis c, chronic alcohol abuse and cirrhosis. Serum elevation of alpha-fetoprotein occurs in a large percentage of patients with hepatocellular carcinoma. Grossly, hepatocellular carcinoma may present as a single mass, as multiple nodules, or as diffuse liver involvement. Microscopically, there is a wide range of differentiation from tumor to tumor (well differentiated to poorly differentiated tumors). Hepatocellular carcinomas quickly metastasize to regional lymph nodes and lung. The overall median survival of untreated liver cell carcinoma is about 4 months. The most effective treatment of hepatocellular carcinoma is complete resection of the tumor. Lately, an increasing number of tumors have been treated with liver transplantation.
  • Malignant liver neoplasm occurring in children and composed of tissue resembling fetal or mature liver cells or bile ducts.
  • Primary malignant neoplasm of epithelial liver cells; it ranges from a well-differentiated tumor with epithelial cells indistinguishable from normal hepatocytes to a poorly differentiated neoplasm; the cells may be uniform or markedly pleomorphic, or form giant cells; associations exist with chronic hepatitis b virus infection, some types of cirrhosis, and hepatitis c virus infection.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 155.0 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
