Question:

MP/H Rules/Histology: What is the correct histology code for a NUT midline carcinoma?

Discussion:

Answer:

Code histology to 8010/3.

NUT carcinoma is identified by the NUTM1 gene rearrangement.

NUT midline carcinomas (NMC) are lethal and morphologically indistinguishable from other poorly diff carcinomas. They are epithelial tumors which can range from undifferentiated carcinomas to carcinomas with prominent squamous differentiation.

A new proposed ICD-O-3 code has been suggested for NUT tumors but it is not yet approved for implementation. Do not use the new code until it is approved for use in the United States.
