I had medial branch block on right side which they kill the nerves in my back. Took 4 mths to get approved and now have to wait for the other side to be approved. What takes so long? I make my monthly payments which i haven't worked since March of 2013 after a failed back surgery. I call and i get the run around. Other than the long wait the insurance is good...just slow for approval.
