After calling yesterday and making sure about the proper process for a walk in and sharing that we would be using Tricare, when we finally got there earlier today, the receptionist said they could not take Tricare. We suggested to do out of pocket and she explained that would be fraud which I still cant understand why. To make it clear this provider appears in the list of providers for Tricare. Already submitted a complaint with the insurance about this issue
