Answer:
For tumors diagnosed 2001-2006:
Code the Histology field to 8046/3 [non-small cell carcinoma] if the pathologist does not provide a more specific histologic type. "Non oat cell" is a synonym for "non-small cell."
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.
