Question:

MP/H Rules/Histology--Breast: How do you code histology for a breast tumor when the comment section of the pathology report compares the current resected specimen with a previous needle biopsy? See Discussion.

Discussion:

A single tumor is described on the breast needle biopsy as "infiltrating lobular carcinoma and ductal carcinoma in situ" and on the lumpectomy specimen as "infiltrating duct carcinoma." Per the COMMENT section on the pathology report: "Tumor resection was compared to previous needle biopsy. The appropriate designation is probably a terminal duct/lobular lesion."

Answer:

For cases diagnosed 2007 or later, assign code 8522 [Infiltrating duct and lobular carcinoma] according to Breast MP/H rule H16. The comment on the lumpectomy pathology report takes both the lumpectomy information and the biopsy information into consideration. "Probable" is an ambiguous term used to code histology.
