Question:
MP/H Rules/Histology--Thyroid: Regarding rule H15, is the mixed code 8340 [Papillary carcinoma, follicular variant] used when there are subtypes of these histologies described, such as a tumor diagnosed with follicular and papillary microcarcinoma or should 8341 [Papillary microcarcinoma] be used?
Discussion:
Answer:
For cases diagnosed 2007 or later:
For coding purposes, this is a papillary and follicular combination that would be coded to the combination code 8340/3 [Papillary carcinoma, follicular variant].
For thyroid cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult, usually less than 1 cm. in diameter.
