Information release

If you would like a friend, relative, doctor, or other person to act for you as your “representative” to ask for a coverage decision (such as whether a service is covered) or make an appeal, you may need to appoint them as your representative. If that person is already legally authorized to act as your representative under State law, you do not need to appoint them to represent you. If you want to appoint someone to be your representative, complete the “Appointment of Representative” form. The form gives that person permission to act on your behalf. It must be signed by you and by the person who you would like to act on your behalf. You must give Mass General Brigham Health Plan a copy of the signed form. You also have the right to hire a lawyer to act for you. You may contact your own lawyer, or get the name of a lawyer from your local bar association or other referral service. There are also groups that will give you free legal services if you qualify. However, you are not required to hire a lawyer to ask for any kind of coverage decision or to appeal a decision.
