Before you schedule an appointment, check with your benefits information packet to see what doctors are covered. Remember, you will need to use a doctor in your network if you want to be covered. If you need to see a doctor who is not in your network, you may still be able to have your prescription glasses covered by filling your prescription elsewhere, but you will have to pay out of pocket for your exam.
When it is time for your eye exam, make sure you talk to your optometrist about your insurance. Most policies require the doctor to seek pre-authorization before they treat you if you are going to be covered. If this is necessary, have the doctor make the necessary calls before your appointment.
