Inquiry Details

#1: 2007 MP/H Rules. Benign, borderline CNS

Question:
MP/H Rules/Histology--Brain and CNS: How should histology be coded for the following 2017 cases (pituitary adenoma vs. prolactinoma)? See Discussion.
Discussion:
1. (2017) Pituitary mass resection with a path diagnosis of
Do we code as prolactinoma when the tumor is immunoreactive for prolactin or must there be a definitive statement of ?
2. (2017) Pituitary lesion on imaging, MD diagnosis of
Current (2007) MP/H rule H9 states when there are multiple histologies in the same branch in Chart 1, code the more specific histology. These histologies are NOT in Chart 1, but prolactinoma seems to be a more specific type of pituitary adenoma. The next rule, H10 states to code the numerically higher code, 8272/0 (pituitary adenoma)?
3. (2017) Imaging diagnosis of pituitary macroadenoma with clinical diagnosis by MD of macroprolactinoma.
Current rules indicate when there is no path specimen that physician reference to type of tumor has priority over imaging.
Will these answers/histologies change with the upcoming 2018 Solid Tumor rules?
Answer:
Code each of these 2017 cases as prolactinoma (8271/0), the more specific histology.
If these cases were diagnosed in 2018, the answer would be the same: code as prolactinoma.
