I am 86 years old, on Medicare Advantage, have no family, and wonder if I need a Power of Attorney? Thanks.

You may appoint a nonfamily member to be a POA. Is there anyone you would consider? I'd likely schedule an appointment with an Elder Law attorney to get information about arranging your affairs. It's your decision as to whether you wish to appoint someone. But, I would at least have an Advanced Healthcare Directive.

Kevin, if you were disabled in some way and unable to handle your finances, what would happen?

If you are unable to continue to take care of yourself, or if you wind up in an ER or are admitted to the hospital and can't speak for yourself, what would happen?

If you are satisfied with the current answer, then I guess you don't need POA. But if you'd prefer to have someone you trust to be able to act for you, then you should probably assign a financial and a medical POA.
