SEER Inquiry System - Question 20061117 Details

For tumors diagnosed prior to 2007:

Assign code 8720/3 [malignant melanoma, NOS] for malignant melanoma arising in a compound nevus. A compound nevus is not the same as a junctional nevus.

ICD-O-3 does not have a specific code for melanoma in a compound nevus. Assign the code for the type of melanoma specified; for example, NOS, superficial spreading, etc.

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.
