Question:

Reportability/Histology--Head and Neck: Is mammary analogue secretory carcinoma (MASC) of the left submandibular gland reportable and how is it coded? See Discussion.

Discussion:

The physician is calling it an indolent tumor, pT3/NX/M0 stage 3 with positive margins. Is the correct code C509, 8502/3?

Answer:

Mammary analogue secretory carcinoma (MASC) is reportable. MASC is a recently described tumor that predominantly arises in the parotid gland. In this case, if the primary site is submandibular gland, assign C080. We contacted our expert pathologist and he stated that the best code to use for MASC is 8502/3. Override any edits triggered by the combination of C080 and 8502/3.
