    Neoplasms

    Note
    • Functional activity
    • All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
    • Morphology [Histology]
    • Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
    • Primary malignant neoplasms overlapping site boundaries
    • A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
    • Malignant neoplasm of ectopic tissue
    • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

    Malignant neoplasm of liver and intrahepatic bile ducts
Approximate Synonyms
  • Cancer of the liver, hepatoblastoma
  • Hepatoblastoma (clinical)
Clinical Information
  • (hep-a-toe-blas-toe-ma) a type of liver tumor that occurs in infants and children.
  • A malignant liver neoplasm composed of immature hepatocytic elements.
  • 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 neoplasm occurring in young children, primarily in the liver, composed of tissue resembling embryonal or fetal hepatic epithelium, or mixed epithelial and mesenchymal tissues. (stedman, 25th ed)
  • A type of liver tumor that occurs in infants and children.
  • Malignant liver neoplasm occurring in children and composed of tissue resembling fetal or mature liver cells or bile ducts.
ICD-10-CM C22.2 is grouped within Diagnostic Related Group(s) (MS-DRG v37.0):
  • 435 Malignancy of hepatobiliary system or pancreas with mcc
  • 436 Malignancy of hepatobiliary system or pancreas with cc
  • 437 Malignancy of hepatobiliary system or pancreas without cc/mcc
