If you are an adult child helping a parent with Medicare, sooner or later you will run into a wall. You call the insurance company about your mom’s claim and they refuse to talk to you. You try to enroll your dad in a new plan and they will only speak with him. You want to compare options on his behalf and the broker, even me, has to verify he has authorized you to be involved. This is not anyone being difficult. It is privacy law working exactly the way it is supposed to.
The fix is to put the right paperwork in place before you actually need it. I have been a Medicare broker in Mesa for 7 years, and I have watched too many families scramble to get power of attorney signed during a hospital stay or after a stroke. Doing it ahead of time, while a parent is healthy and mentally clear, takes about an hour and saves an enormous amount of stress later.
This guide is about the practical pieces of helping with a parent’s Medicare in Arizona, including what documents you actually need, what each one lets you do, and how to handle the conversations with insurance companies when you need to act on a parent’s behalf.
Why HIPAA Stops You at the Door
The Health Insurance Portability and Accountability Act, or HIPAA, protects the privacy of your parent’s health information. It applies to insurance companies, doctors, hospitals, pharmacies, and Medicare itself. By default, none of those entities can share your parent’s medical or insurance information with anyone, including their adult children.
This is the case even if you are listed as an emergency contact. It is the case even if you are paying their bills. It is the case even if you have been their primary caregiver for years. Without specific authorization, you have no legal standing to access their information or make decisions on their behalf.
There are a handful of ways to gain that authorization. The right ones to set up depend on what you actually need to do.
The Three Documents Most Families Should Consider
There are three legal instruments that come up most often in Medicare situations. Not every family needs all three, but understanding them helps you decide what is right for your situation.
The first is a Medicare Authorized Representative form, often called a Form 1696 or a similar plan-specific form. This document gives a named person the right to act on the Medicare beneficiary’s behalf for Medicare-related matters. With this on file, an insurance company will speak to you about your parent’s plan, claims, appeals, and enrollment. It is the lightest-weight option and is sufficient for most ongoing plan management. It is also revocable at any time and can be limited in scope.
The second is a HIPAA Authorization form. Each carrier has its own version. Once your parent signs and submits one, the carrier can share information with the people listed. This is helpful for getting claim explanations and benefits information but does not let you make decisions or sign on your parent’s behalf.
The third is a durable power of attorney, sometimes split into a financial power of attorney and a healthcare power of attorney. A financial POA gives you legal authority to handle financial matters, including paying premiums, signing enrollment forms, and dealing with insurance and Social Security. A healthcare POA, also called a healthcare proxy or healthcare surrogate in some states, lets you make medical decisions if your parent cannot make them themselves. In Arizona, these are governed by state law and need to be drafted and signed properly to be valid.
For most adult children helping with day-to-day Medicare, a Medicare Authorized Representative form plus a HIPAA authorization is enough. For situations where a parent’s cognitive abilities are declining, where they are unable to make their own decisions, or where you may need to act broadly on their behalf, a durable power of attorney is essential.
How to Get the Documents Set Up
Setting up the basic Medicare authorizations is free and takes about 30 minutes. Each insurance company has a form on its website. You and your parent fill it out together, your parent signs, you submit it. The carrier processes it within a few business days, and from that point forward, you can call and speak with them about your parent’s plan.
Setting up a durable power of attorney is a bigger deal. In Arizona, the documents need to be signed in front of a notary, and the healthcare POA also requires a witness who is not a family member or healthcare provider. You can use a fill-in-the-blank form available from the Arizona Attorney General’s office, hire an estate planning attorney to draft custom documents, or use an online service. For most families, the Attorney General forms are sufficient and free. For families with complex assets or specific concerns, an attorney is worth the cost.
The biggest mistake I see is families waiting until a crisis. Once a parent has had a stroke, a serious cognitive decline, or a hospitalization that affects their decision-making capacity, they may no longer be legally able to sign these documents. At that point, the family has to go through guardianship or conservatorship in court, which is expensive, slow, and stressful. Doing the paperwork while everyone is healthy is one of the kindest gifts you can give your future self.
What You Can Actually Do With Each Authorization
Knowing what authorization gives you what powers helps you avoid frustration on the phone with insurance companies. Here is the practical breakdown.
With a Medicare Authorized Representative form filed with a specific carrier, you can call that carrier, discuss the plan, ask about claims, file appeals, request enrollment forms, and generally handle plan administration. You cannot enroll your parent in a different plan, change their address, or modify their banking information for premium payments. Those actions require their direct involvement.
With a HIPAA authorization, you can request and receive explanations of benefits, claim information, and medical records. You cannot make decisions or take actions.
With a financial power of attorney that includes Medicare and insurance authority, you can do everything above plus enroll, disenroll, change plans, sign forms on your parent’s behalf, and handle premium payments. The carrier will need to see and verify the document, which adds a step.
With a healthcare power of attorney, you can make medical decisions if your parent cannot. This includes consenting to treatments, choosing providers, and making end-of-life decisions consistent with your parent’s wishes. Healthcare POAs do not generally cover insurance and plan decisions, which is why both types are useful.
A Practical Workflow for Working With a Broker
When I take on a new client whose adult child is involved, here is what I usually have us set up at the start.
Your parent and I have an initial conversation. They are the client. They make the decisions. Even with you in the room, my job is to make sure they understand and consent.
Your parent signs a designated representative form for me. This lets me communicate with you on their plan, share documents, and answer your questions. Most carriers do not let me share plan details with anyone outside the household without this.
I help your parent fill out the carrier authorization forms with whichever insurance company they end up enrolling with. We list you as an authorized contact and submit the form during the application.
If your parent has not yet set up power of attorney documents, I usually suggest they do so. I am not a lawyer and cannot draft the documents, but I can point you to the Arizona Attorney General resources or recommend an estate attorney if you want one.
This setup is fast, free, and gives you the ability to actually help when needed. Without it, every call you make on your parent’s behalf turns into a runaround.
Common Situations Where This Matters
A few patterns I see all the time.
A claim gets denied. Your parent does not understand the explanation of benefits and asks you to look at it. Without a HIPAA authorization or representative form on file, the insurance company will not even confirm the claim exists when you call. With the right form on file, you make one call and resolve it.
Your parent is in the hospital and a discharge planner asks about their Medicare coverage. If you have a healthcare POA and a Medicare representative form, you can answer questions, coordinate with the social worker, and arrange home health or skilled nursing without your parent having to manage it from a hospital bed.
Your parent is starting to forget things. They miss premium payments. They lose paperwork. With a financial POA and proper carrier authorization, you can take over premium payments, monitor their plan, and step in to handle administrative tasks before things start falling apart.
Your parent passes away. The family needs to cancel coverage and handle final claims. Without authorization, the insurance company will require you to provide a death certificate and proof of estate authority, which can take weeks. Having a clear paper trail set up in advance shortens this process significantly.
What to Do Before You Need It
If your parent is healthy, mentally clear, and willing to have the conversation, here is what I would do this month.
Get a Medicare Authorized Representative form on file with their current insurance carrier. Free, fast, and lets you handle plan questions immediately.
Get a HIPAA authorization on file with their primary doctors and any specialists. This lets you participate in health discussions when your parent invites you.
Sit down with your parent and decide whether durable power of attorney makes sense. For most families with parents in their late 60s and beyond, the answer is yes. The Arizona Attorney General has free forms online. An estate attorney is a few hundred dollars if you want professional help.
Once these are in place, you can be the helpful adult child your parent needs without running into walls every time you try to act on their behalf.
