Question:

Histology (Pre-2007)--Lung: How is a poorly differentiated non-small cell carcinoma with "squamoid differentiation" coded?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Squamoid and squamous are synonymous. Squamoid is non-standard terminology. It means "squamous like" and is a synonym of squamous.

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.
