The main difference between being in network vs. out of network is the level of reimbursement you will receive from your insurance company.  When GFD is in network with an insurance company, we have signed a contract with that insurance company to provide care for their patients at a defined rate of reimbursement. Sometimes there is no difference between in or out of network reimbursement rates. A more comprehensive or complete answer can be obtained by the policy holder calling the insurance company, searching the insurance company web site or contacting the employers Human Resource Department.
