Question:
Discussion:
How are terms that are modified by parentheses to be interpreted? Do terms in parentheses modify the stated diagnosis and thus have priority over the stated diagnosis? Or would rule H17 apply and histology would be coded as duct and other carcinoma? For this case, the wording of the diagnosis and use of parentheses seem to indicate that tubular is a type of ductal carcinoma. Tubular is not listed as a specific duct carcinoma in the MP/H rules histology tables for breast.
