# Neoplasms (C00-D48)Neoplasms (C00-D48)

    This chapter contains the following broad groups of neoplasms:
    C00-C75 Malignant neoplasms, stated or presumed to be primary (of specified sites), and certain specified histologies, except neuroendocrine, and of lymphoid, hematopoietic and related tissue

       C64-C68 Malignant neoplasms of urinary tract

    Notes: 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. To identify the morphology for the majority of Chapter 2 codes that do not include the histologic type, comprehensive separate morphology codes are provided. These morphology codes are derived from the International Classification of Diseases for Oncology (ICD-O).
    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).
