Power of attorney, Medicare authorized representative, Social Security representative payee, they sound alike but do different jobs. A plain-English guide for adult children on which one you actually need.
When you start helping a parent, you run into a confusing pile of similar-sounding roles: power of attorney, Medicare authorized representative, Social Security representative payee. They are not the same thing, and you may need more than one. Here's what each does and which you actually need.
Power of Attorney (POA)
A POA is a legal document set up under your state's law, usually with an elder-law attorney, that gives you broad authority over your parent's medical and/or financial decisions. It's the broadest tool. But here's the catch most families don't expect: Medicare does not create or accept a POA on its own forms, so a POA alone won't let you talk to Medicare or file an appeal.
Medicare authorized representative (Form CMS-1696)
This appoints you to act for your parent in a specific Medicare appeal or grievance, filing it, sending evidence, and speaking for them on that matter. It's narrow and matter-specific, and both of you sign it. This is the form you need when a claim is denied.
Authorization to disclose information (Form CMS-10106)
This is about access, not decisions. It lets Medicare share your parent's claims and enrollment details with you and talk to you at 1-800-MEDICARE. Your parent signs it. It's usually the first form a caregiver needs, and it does not, by itself, let you file an appeal.
Social Security representative payee
This is a separate role handled by the Social Security Administration, not Medicare. A representative payee manages a person's Social Security benefit payments when they can't manage them on their own. If that's your situation, you apply through Social Security, it's different from all of the Medicare forms above.
So which do you actually need?
Match the form to the job: to talk to Medicare and see claims, use CMS-10106; to handle an appeal, add CMS-1696; to make broad medical or financial decisions, you need a POA; to manage their Social Security checks, apply as a representative payee with SSA. Often you'll need more than one, and they work together, a POA does not replace the Medicare forms.

Do I need Power of Attorney to help my parent with Medicare?
Usually no. To talk to Medicare and see your parent's information you use Form CMS-10106, and to handle an appeal you use Form CMS-1696. A POA is broader and often still requires those Medicare forms on top, so for Medicare-specific help the two CMS forms are usually enough.
What's the difference between a POA and a Medicare authorized representative?
A power of attorney is a broad state legal document covering medical and/or financial decisions. A Medicare authorized representative (CMS-1696) is a narrow role that lets you act for your parent in a specific Medicare appeal or grievance. They serve different purposes and can be used together.
What is a Social Security representative payee?
It's a person appointed through the Social Security Administration to manage someone's Social Security benefit payments when they can't manage them themselves. It's separate from Medicare's forms and from a power of attorney.
Can one form cover everything?
No. Access to information (CMS-10106), representation in an appeal (CMS-1696), broad decision-making (a POA), and managing Social Security payments (a rep payee) are four different jobs with four different tools. Most caregivers set up whichever ones their situation calls for.
