We are being denied ALL of our facility fee charges for our ASC from Medicaid due to "Taxonomy codes not supporting our CPTs."
Our ASC is billing out with the taxonomy code for ambulatory surgery center, and a rep from Medicaid tells me that we should be using the taxonomy code for Gastroenterology.
We are managed by a large corporation, and they are insisting that the gastroenterology taxonomy code is not needed, and that I should be billing out with a TC and 26 modifier instead.

any input would be greatly appreciated!!!
