Question:

MP/H Rules--Breast: What histology code is used for lobular with focal ductal features? Do we ignore the focal features and code as lobular or do we use the combination code for duct and lobular?

Discussion:

Answer:

For cases diagnosed 2007 or later, use rule H14 and assign code 8520 [lobular]. Ignore histologies described as "focal," "foci," or "focus." This instruction will be added to the next version of the MP/H manual.
