If they approve the trial they will approve the final unit. When they denied it back in October they said it was because the procedure wasn't "proven"...and they sited that it had not been PUBLISHED. It is FDA approved for CRPS...so it's not an off label use or anything like that. My insurance carrier was the only one at the office denying the treatment (not just for me...but any patients with the same insurance). Now that it's been published they have been approving it...so hopefully that means smooth sailing at this point. Fingers crossed anyway.
