Yes. A person with dementia can still make their own Medicare coverage choices as long as they have legal capacity, meaning they understand each choice and its consequences. A dementia diagnosis alone does not remove that right. According to the Alzheimer's Association, the person keeps the right to make medical and Medicare decisions while capacity remains, as explained in the Alzheimer's Association legal planning guide.

When Does Decision-Making Ability Remain?
Many people in the early stage of Alzheimer's can still understand information and take part in legal, financial, and care choices. That window makes early action important.
Families should treat planning as urgent after diagnosis. Complete documents while the person can still explain wishes and grasp results.
What Medicare Visits Cover Thinking and Planning?
Medicare's yearly Wellness visit includes a check for dementia signs. According to Medicare, the visit looks for trouble remembering, concentrating, managing finances, and making everyday decisions, as described on Medicare's yearly Wellness visit page.
The visit also offers a chance to discuss advance directives. Medicare Part B also covers a separate cognitive assessment and care-plan visit. According to Medicare, it reviews cognitive function, helps establish or confirm dementia, builds a symptom care plan, and develops or updates an advance care plan, as described on Medicare's cognitive assessment coverage page.
How Do You Name Backup Help in Time?
Advance directives state health preferences for later use. Federal guidance from Alzheimers.gov says they apply only if the person becomes unable to decide, including a durable power of attorney for health care that names a proxy.
Create these papers while understanding remains. Financial and estate directives require legal capacity at signing.
- Choose a trusted health proxy and backup proxy.
- Write care wishes and review them with a clinician.
- Sign financial and estate papers while choices are clear.
- Share copies with family, doctors, and the proxy.
Where Do Family Permissions Stop?
A state power of attorney alone does not automatically give authority with Medicare. An authorized Medicare representative also cannot make medical treatment choices without a separate health-care proxy or advance directive.
For coverage disputes, another person needs formal permission. According to Medicare, family, friends, advocates, or attorneys can use the Appointment of Representative form CMS-1696 to help file appeals, as explained on the federal appeals forms page. File that form before an appeal deadline passes.
