Answer:
For tumors diagnosed prior to 2007:
Code the Histology and the Grade, Differentiation fields to 8140/33 [adenocarcinoma, poorly differentiated].
The term "non-small cell carcinoma" is used to represent a broad category of epithelial cancers. Non-small cell carcinoma [8046/3] is grouped in the ICD-O-3 under "Epithelial Neoplasms, NOS." The term can be used by a pathologist when he rules out the fact that the patient has a small cell cancer by stating that the malignancy is a non-small cell type of cancer. In this case, the type of non-small cell cancer present in the specimen is adenocarcinoma.
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.
