Question:

Histology (Pre-2007)--Corpus Uteri: How should this field be coded when the D&C which shows "adenocarcinoma with mucinous and papillary features" and the TAH demonstrates only "endometroid carcinoma"? See Discussion.

Discussion:

Should Histology be coded to 8380 [endometroid adenocarcinoma] because it is the most representative sample or to 8323 [mixed cell adenocarcinoma], per the Complex Morphology Coding Guidelines? The instructions in the Guidelines seem to imply that it is most important to represent combination histologies first, with majority (most representative sample) of tumor having a lower priority.

Answer:

For tumors diagnosed prior to 2007:

Code Histology based on the pathology report from the most representative tissue. For the example above, code Histology to 8380 [Endometroid adenocarcinoma] based on the TAH/BSO pathology report.

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.
