Question:

Histology (Pre-2007)--Testis: What code is used to represent the histology of "mixed germ cell tumor, embryonal carcinoma and mature teratoma" of the testis? See discussion.

Discussion:

Is the teratoma required to be described as "immature" or "malignant" in order to use the histology code of 9081/3 [mixed embryonal carcinoma and teratoma]?

Answer:

For tumors diagnosed prior to 2007:

Code the Histology field to 9081/3 [Teratocarcinoma, mixed embryonal carcinoma and teratoma], in both ICD-O-2 and ICD-O-3.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
