When I was denied by United Healthcare 2 years ago, I was advised by Dr. Getson's office to use the simple phrase "ketamine infusion therapy is an accepted protocol for the treatment of RSD/CRPS.".

I won my case with UHC upon appeal ( the 3rd or 4th time), with just those words. But UHC never remitted what they said they would in payment on my account. I am extremely fortunate that eventually I won my case in WC court in RI, and I don't have to fight with UHC for them to pay their fair share of the infusion expenses.

Good luck!
