Question:

MP/H Rules/Histology--Skin: How is the histology coded for a "malignant baso-melanocytic tumor" arising in the skin of right shoulder?

Discussion:

Answer:

Code the histology as melanoma, NOS [8720/3].

This is a malignant skin tumor with both melanoma and basal cell carcinoma histologies. There is no ICD-O-3 code for this entity. Per our subject matter expert, code the histology to 8720/3 [melanoma, NOS] and document the diagnosis of malignant baso-melanocytic tumor in a text field because melanoma is reportable to SEER and basal cell carcinoma is not.
