Answer:
The difference is that 8150 is for islet cell tumors. The preferred name was changed by WHO/IARC to reflect the current language used by pathologists to describe islet cell tumors [8150].
The 8240 histology code added the neuroendocrine tumor, grade 1, low or well differentiated terms to the carcinoid ICD-O name.
Islet cell tumors are more aggressive than the pancreatic NET tumors. Treatment and prognosis are determined by the histologic type. While the histology code 8150 is not new, the histology name has been updated.
