Question:

MP/H Rules/Histology--Thyroid: How is histology coded for a thyroid tumor described as "predominantly papillary carcinoma, tall cell variant, follicular type"?

Discussion:

Answer:

For cases diagnosed 2007 or later, assign code 8340 [Papillary carcinoma, follicular variant] according to rule H15 for Other Sites.

"Predominantly" and "type" indicate specific histologies. "Variant" does not. See rule H13. The histology in this case is papillary and follicular. Tall cell variant is ignored.
