APPENDIX A
                        MORPHOLOGY OF NEOPLASMS

The World Health Organization has published an adaptation of the
International Classification of Diseases for oncology (ICD-O). It contains
a coded nomenclature for the morphology of neoplasms, which is reproduced
here for those who wish to use it in conjunction with Chapter 2 of the
International Classification of Diseases, 9th Revision, Clinical Modification.

The morphology code numbers consist of five digits; the first four identify
the histological type of the neoplasm and the fifth indicates its behavior.
The one-digit behavior code is as follows:

    /0 Benign

    /1 Uncertain whether benign or malignant
        Borderline malignancy

    /2 Carcinoma in situ
        Intraepithelial
        Noninfiltrating
        Noninvasive

    /3 Malignant, primary site

    /6 Malignant, metastatic site
        Secondary site

    /9 Malignant, uncertain whether primary or metastatic site

In the nomenclature below, the morphology code numbers include the behavior
code appropriate to the histological type of neoplasm, but this behavior code
should be changed if other reported information makes this necessary. For
example, "chordoma (M9370/3)" is assumed to be malignant; the term "benign
chordoma" should be coded M9370/0. Similarly, "superficial spreading
adenocarcinoma (M8143/3)" described as "noninvasive" should be coded M8143/2
and "melanoma (M8720/3)" described as "secondary" should be coded M8720/6.
 
The following table shows the correspondence between the morphology code and
the different sections of Chapter 2:

Morphology Code ICD-9-CM Chapter 2
Histology/Behavior

Any 0 210-229 Benign neoplasms
M8000-M8004 1 239 Neoplasms of unspecified nature
M8010+ 1 235-238 Neoplasms of uncertain behavior
Any 2 230-234 Carcinoma in situ
Any 3 140-195 Malignant neoplasms, stated or
                  200-208 presumed to be primary
Any 6 196-198 Malignant neoplasms, stated or
                                     presumed to be secondary

The ICD-O behavior digit /9 is inapplicable in an ICD context, since all
malignant neoplasms are presumed to be primary (/3) or secondary (/6)
according to other information on the medical record.

Only the first-listed term of the full ICD-O morphology nomenclature appears
against each code number in the list below. The ICD-9-CM Alphabetical Index
(Volume 2), however, includes all the ICD-O synonyms as well as a number of
other morphological names still likely to be encountered on medical records
but omitted from ICD-O as outdated or otherwise undesirable.

A coding difficulty sometimes arises where a morphological diagnosis contains
two qualifying adjectives that have different code numbers. An example is
"transitional cell epidermoid carcinoma." "Transitional cell carcinoma NOS"
is M8120/3 and "epidermoid carcinoma NOS" is M8070/3. In such circumstances,
the higher number (M8120/3 in this example) should be used, as it is usually
more specific.
