  • C00-D49
    2022 ICD-10-CM Range C00-D49


    • 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).

    Hodgkin lymphoma
Clinical Information
  • A monoclonal b-cell lymphoproliferation in the vast majority of cases. It is characterized by a bimodal age distribution (15-30 years of life and late life) and is often associated with ebv infection. In less than 5% of cases it is a monoclonal proliferation of t-lymphocytes. Morphologically, it is characterized by the presence of reed-sternberg cells and mononuclear hodgkin cells. The reed-sternberg and mononuclear hodgkin cells are cd30 positive in nearly all cases and cd15 positive in the majority of cases.
  • The most common type of hodgkin lymphoma, which is a cancer of the immune system. Classical hodgkin lymphoma is marked by the presence of a type of cell called the reed-sternberg cell.
