Question:

Histology (Pre-2007)--Head & Neck: How is a "sinonasal undifferentiated carcinoma (SNUC)" coded?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Code histology to 8020 [carcinoma, undifferentiated]. "Sinonasal" refers to anatomic location of primary site not histology.

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.
