Stay away stay away stay away at least from the Concord office. We went in for a knee consultation and we're recommended for a symbis gel 3 part injection as cortisone has a short effect on my wife's knee. We were told we had to wait for insurance preauthorization. wife was scheduled for 5 weeks later. go in for first appointment and they cancel appointment at their office (little freaking late)on site and say Preauthorization hasn't been completed. I call up and demand an explanation as to why she had to go in and be cancelled on at the office and why a preauthorization took 5 weeks. we were called and told the organization was approved and scheduled for the next day. after getting the three injections, about a week apart, we get a bill no insurance coverage and to add insult to injury the injections are having side effects and we have been waiting three days for a call back from the administering physician after speaking to a nurse about her not being able to stand on knee that injections were put into almost three weeks later horrible service before after care a follow up wasn't even scheduled, we have to pay extra for that, the injections were billed seperatly everything is a la cart STAY AWAY.
