Question:

Histology (Pre-2007)--Melanoma: How is histology coded for a final pathology diagnosis of "malignant melanoma, NOS" that is clinically described as a nevus?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Code 8720 [malignant melanoma]. Assign the histology code based on the histology stated in the final diagnosis on the pathology report. The pathology report must say melanoma arising in junctional nevus to use the code 8740/3 [Malignant melanoma in junctional nevus].

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.
