As noted previously, the ICD-10 categories C00-C97 include
a few categories that are either based on morphology or denote
metastatic or secondary neoplasms which are described by the
behavior code in ICD-O. Table 5 shows the ICD-10 categories
omitted from the topography section of ICD-O.

The C81-C96 section of ICD-10 is used for malignant neoplasms
of lymphoid, hematopoietic and related tissues. In ICD-O,
Third Edition, these are assigned specific morphology codes
and the behavior code /3. The morphology code, combined with
the appropriate topography code in the range C00-C80, expresses
the complete diagnosis. For example, in ICD-10, lymphocytic
lymphoma of the stomach is coded C83.0. In ICD-O, small cell
(diffuse) non-Hodgkin lymphoma would be coded to stomach C16.9
and the morphology to M-9670/3 (diffuse small cell lymphoma).
The C97 category in ICD-10 is not included in ICD-O as each
primary site is usually coded separately. Guidelines for determining
what constitutes multiple primaries vary among countries.
