Question:

Histology (Pre-2007)--Skin: Are "atypical melanocytic hyperplasia" and "severe melanotic dysplasia" synonyms for melanoma in situ?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

No. SEER determines its reportable list from the ICD-O-3. The above terms are listed as tumor-like lesions and conditions, but are not in situ or malignant.

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.
