Question:

Histology (Pre-2007)--Melanoma: How is histology coded if the final diagnosis is "melanoma" and only in the comment section of the pathology report is there an indication of "Type: Lentigo Maligna. Cell Type: Small Cell"?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Code the histology as 8742 [lentigo maligna melanoma]. Code the specific histologic type, even if stated only in the comment section.

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.
