Question:

MP/H Rules/Histology--Breast: How is histology coded for an "infiltrating papillary carcinoma" of the breast when there is no mention of ductal or adenocarcinoma in the pathology report?

Discussion:

Answer:

For cases diagnosed 2007 or later, assign histology code 8503 [Papillary adenocarcinoma]. Rule H14 applies.

ICD-O-3 code 8050 does not apply in this case. Refer to the numeric listing in ICD-O-3. 8050 is a squamous cell neoplasm. Papillary carcinoma of the breast is NOT a squamous cell neoplasm. It is a neoplasm of the breast parenchyma - ducts, lobules or connective tissue. 8503 is the correct code in this case.
