Question:

Histology (Pre-2007): Can we ever code this field using a more specific cell type from a metastatic site specimen rather than to a less specific cell type from the primary site specimen? See Discussion.

Discussion:

The histology for a metastatic deposit biopsy is mucin-producing adenocarcinoma. This report states that the primary site is the stomach. It is more specific than the histology from the stomach biopsy described as adenocarcinoma, NOS.

Answer:

For tumors diagnosed prior to 2007:

Code the histology for the case example to 8481/3 [mucin-producing adenocarcinoma], the more specific histology.

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.
