Inquiry Details
References:
2007 MP/H Rules. Other Sites
Question:
MP/H Rules/Histology--Skin: What histology code and MP/H Rule apply to a skin primary with the final diagnosis, ? See Discussion.
Discussion:
The patient had an upper arm shave biopsy with final diagnosis of basaloid carcinoma with squamous and neuroendocrine differentiation. The pathologist also comments: Further resection was negative for residual malignancy.
Would SINQ 20150033 apply, thus resulting in final histology of carcinoma with neuroendocrine carcinoma (8574/3)?
Answer:
Assign 8574/3 according to Other Sites rule H17 for basaloid carcinoma with squamous and neuroendocrine differentiation.
There is no combination code that includes basal cell, squamous, and neuroendocrine. We can combine basal cell with squamous, 8094/3, or carcinoma with neuoendocrine differentiation, 8574/3. Rule H17 directs us to assign the higher code, 8574/3.
