Is it possible to use segmentations as a dimension in Revenue Cycle Explorer reports?
Or if not, is there any way around it?
Go to the Admin area and sync the fields to revenue explorer. They should then become visible a while later.
Segmentation isn't a field that can be synced. You can create a custom field and populate the segment values in there and sync that field over to RCE by using the instructions in the above product document.
