Appendix A - Morphology of Neoplasms



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as a number of other morphological names still likely to be encountered on medical records but omitted from ICD-O as outdated or otherwise undesirable.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 carcinomas." "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.
