MP/H Rules/Histology/Behavior--Ovary: How are these fields coded for a 20 cm borderline mucinous tumor with a 0.3 cm minor focus of intraepithelial carcinoma of the ovary that the pathologist stages as T1a?
MP/H Rules/Histology/Ambiguous terminology: Can synonyms of listed terms, such as "variety" for the list termed "type," be used to code a more specific histology? See Discussion.
MP/H Rules/Histology--Urinary System: What is the histology code for a 2007 and later diagnosis of papillary carcinoma of the urinary system organs? See Discussion.
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?
MP/H Rules/Histology--Thyroid: Is a "papillary carcinoma of the thyroid" coded to 8260/3 [Papillary adenocarcinoma] per the ICD-O-3 because it lists "papillary carcinoma of the thyroid" as a synonym for that code or should it be coded to 8050 [Papillary carcinoma, NOS]?
MP/H Rules/Histology--Thyroid: How should histology be coded for a diagnosis of "papillary sclerosing carcinoma" with an additional description of the tumor being "nonencapsulated"? See Discussion.
MP/H Rules/Histology--Thyroid: How many primaries are to be reported and what histology is to be coded for an anaplastic/undifferentiated thyroid carcinoma with sarcomatoid transformation likely arising in association with a papillary thyroid carcinoma? Thyroid contains one tumor: 12.5 cm in greatest dimension...almost completely replaces entire thryroid gland.
MP/H Rules/Histology--Thyroid: How many primaries and what histology(ies) are coded when the pathology report shows a, 1.9 cm Hurthle cell carcinoma, probable follicular variant of papillary carcinoma, with Hurthle cell features and a 2 mm focus of follicular variant, papillary carcinoma? See Discussion.
