Neoplasms C00-D49 >

 

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).
