Our recommendation is that you first speak to your benefits coordinator. He/she give you advice on the right person to contact at your insurance company. Take careful notes on the conversations you have with your insurers and health care professionals. Include names, dates and complete descriptions of your discussions.
If after speaking with your insurance company’s customer service department you are not granted coverage, ask for a claims supervisor. If that is not effective, search your health and dental plans for information on the appeals process. Appeals are not easy, but they might be the best way for you to get coverage. If need be, consult an attorney who specializes in this area.
