Question:

MP/H Rules/Histology--Melanoma: How should histology be coded for a melanoma arising in a compound nevus, NOS or a nevus, NOS?

Discussion:

Answer:

For cases diagnosed 2007 or later, assign code 8720 [Melanoma, NOS] to melanoma arising in a nevus that does not have a specific code or to melanoma arising in a nevus, NOS.

Currently, ICD-O-3 does not have a specific classification for a melanoma arising in a compound nevus.
