Question:

Histology (Pre-2007): Do the terms "keratinizing" or "non-keratinizing" have to be present in the final diagnosis to use codes 8071 through 8073? See discussion.

Discussion:

Should "squamous cell carcinoma, small cell variant" be coded to 8073 even though the final diagnoses does not include the phrase "non-keratinizing?"

Answer:

For tumors diagnosed prior to 2007:

It is acceptable to assign code 8073/3 for squamous cell carcinoma, small cell, NOS. Code squamous cell carcinoma, large cell, NOS to 8072/3. Code to non-keratinizing unless the pathology report specifies keratinizing.

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.
