Question
MP/H Rules/Multiple primaries--Breast: Does breast Rule M10, 'Tumors that are lobular (8520) and intraductal or duct are a single primary” apply if you have two tumors in the same breast, one ductal and the other tubulolobular (8524) or are they considered separate primaries per Rule M12?

Discussion


Answer
Apply Rule M10 to this case. Tubulolobular is now classified as a variant of lobular. Code to lobular, NOS (8520) because Tubulolobular does not have a specific ICD-O-3 code.
