My wife was involved in an auto accident in 2007. That same year and in 2008, she went to a physical therapist. The physical therapist did not file with either the Auto Insurance Co. nor with our health insurance company. Now the physical therapist is claiming we are personally responsible. I told them that they were provided insurance information and since they did not file, we were not responsible for the total amount. IF the physical therapist now files, it will be denied by the insurance company because it wasn't timely filed. Can the physical therapist come after us because they didn't file with our insurance company?
