Question:

Primary Site--Melanoma: How would this field be coded for a pleural effusion consistent with metastatic melanoma and "no skin lesions?"

Discussion:

Answer:

Code primary site as C44.9 [Skin, NOS]. ICD-O-3 does not list a suggested site code for 8720/3 because melanoma can arise in other parts of the body. However, C44.9 [Skin, NOS] is the default when the primary cannot be found.
