One of the physicians that we bill for has a couple of questions? Are the reimbursements higher in an out patient surgery center than a regular imaging center? Would there be any difference in a MRI vs. a MRI under general anesthesia??

I found some information about billing CPT code 01922 with the MRI for the anesthesia, does anyone have any experience billing anesthesia with MRI/CT?? Any payment issues?

Thank you in advance for your help,
