How to Help an Aging Parent Review Medicare During Open Enrollment

Medicare Open Enrollment can look like an insurance decision. For a family caregiver, it is often a practical care-planning decision too. You may be the person who knows which prescriptions your parent actually takes, which doctors they depend on, which pharmacy they use, and what changed in their health care over the past year.

That makes this annual enrollment period a useful time to compare the Medicare coverage on paper with the care your parent is actually using.

You do not need to become a Medicare expert. You need a reliable way to gather the right information, notice what changed, ask better questions, and make sure an important coverage decision does not depend on memory alone.

Medicare Open Enrollment 2026 at a glance
  • September: Review the Annual Notice of Change and Evidence of Coverage from the current plan.
  • October 1: Start comparing current Medicare health or drug coverage with available options for 2027.
  • October 15–December 7: Medicare Open Enrollment. Eligible coverage changes can be made during this period.
  • January 1, 2027: Changes made during Open Enrollment generally take effect.

Medicare states that Open Enrollment runs from October 15 through December 7 each year. During this period, people with Medicare can make eligible changes to Medicare Advantage and prescription drug coverage or switch between Medicare Advantage and Original Medicare. Changes generally take effect January 1 of the following year.

The most useful caregiver question is not “Which plan looks best?” It is: “What will be different next year if my parent keeps the coverage they have now?”

Why caregivers should review Medicare coverage every year

A plan that worked well this year may still be the right choice next year. But that is something to confirm rather than assume.

Medicare health and drug plans can change coverage, costs, provider arrangements, pharmacy arrangements, and other plan details from one year to the next. Your parent's needs can change too.

Maybe a new specialist became important. A prescription was added. A preferred pharmacy changed. Your parent started using more outpatient care. They moved, travel more often, or now rely on services that did not matter twelve months ago.

The goal of Open Enrollment is not to switch plans every year. It is to make the choice using current information.

Start with the plan your parent already has

Before comparing new options, gather the information about the current coverage. Starting with plan advertisements before you understand the existing plan can make the comparison harder than it needs to be.

  • Current Medicare card and health or drug plan information.
  • Annual Notice of Change, or ANOC.
  • Evidence of Coverage, or EOC.
  • A current prescription medication list.
  • Preferred pharmacy or pharmacies.
  • Primary care doctor and regularly used specialists.
  • Hospitals, clinics, or facilities used regularly.
  • Other insurance or prescription coverage that may interact with Medicare.

Medicare says plans generally send the Annual Notice of Change and Evidence of Coverage in September. The ANOC describes changes that will take effect in January. The EOC provides more detailed information about coverage and costs.

1. Read the Annual Notice of Change before comparing plans

Do not treat the Annual Notice of Change as routine mail. Read it with one practical question in mind:

What changes in January if my parent does nothing and keeps this plan?

Look for changes involving premiums, deductibles, copayments or coinsurance, prescription coverage, provider or pharmacy arrangements, and other rules that could affect services your parent regularly uses.

A simple caregiver note

“Current: Mom uses this pharmacy every month. Changing: the plan notice says pharmacy arrangements are changing. Question: will this pharmacy still work the same way under the plan next year?”

2. Compare the real medication list

Prescription coverage can create meaningful differences between plans, especially when an older adult takes several medications.

Use the medications your parent actually takes. Do not compare plans using an old list, a partial list, or what everyone remembers from the last appointment.

You can use Medicare’s official Plan Compare tool to compare available Medicare Advantage and drug plans in your parent’s area, review plan costs and services, and enter the prescriptions they actually take to estimate monthly and yearly drug costs.

  • Is each current prescription covered by the plan?
  • What estimated cost applies to the medication under that plan?
  • Is the pharmacy your parent normally uses in the plan's network?
  • Does the plan identify preferred pharmacies that could affect cost?
  • Are there plan requirements attached to any medication your parent uses regularly?
Medication safety comes before insurance convenience. A caregiver can compare drug coverage and identify questions, but medication changes belong with the appropriate prescriber or pharmacist. Do not stop, substitute, split, crush, change the dose of, or otherwise alter a prescribed medication because another option appears less expensive under a plan.

3. Check the doctors and facilities your parent actually uses

A plan comparison becomes much more useful when it is based on real care rather than a general statement that a plan has a “large network.”

Make a short list of the clinicians and facilities your parent depends on most.

Primary care doctor

Verify whether the doctor participates under the plan and whether any relevant plan rules affect access.

Regular specialists

Check the specialists your parent sees for ongoing care and whether referral, network, or authorization requirements may apply.

Hospitals and health systems

If your parent regularly receives care through a particular hospital or health system, include it in the comparison rather than assuming it works the same way under every plan.

Pharmacy

Verify the pharmacy your parent actually uses and whether its network or preferred status changes expected costs.

Provider participation can change. Verify current information with the plan and, when appropriate, the provider rather than relying only on what was true last year.

4. Compare more than the monthly premium

The lowest monthly premium is not automatically the lowest-cost option for the year. Look at the combination of costs that applies to the care your parent is realistically likely to use.

  • Monthly plan premium, if applicable.
  • Deductibles that apply.
  • Copayments or coinsurance for regularly used services.
  • Estimated prescription costs using the current medication list.
  • Costs related to frequently used doctors or specialists.
  • Applicable out-of-pocket limits.
  • Costs or restrictions that matter if your parent travels or lives in more than one area.

A plan can look inexpensive when viewed through one number and much less attractive when viewed through the pattern of care your parent actually uses.

5. Compare the plan with what changed in your parent's life

One of the easiest ways to make Open Enrollment more manageable is to stop looking at every possible health need and focus first on what changed since the previous year.

  • New prescriptions or important medication changes.
  • New doctors or specialists.
  • A hospitalization or new follow-up care.
  • More frequent therapy, testing, or outpatient visits.
  • A move or regular travel to another area.
  • A change in preferred pharmacy.
  • Greater need for family caregiver involvement.
  • New dental, vision, hearing, or other practical needs relevant to the options being compared.

6. Check the plan rules that could create friction later

Coverage is not only a list of benefits. How a plan works can matter when a caregiver is coordinating appointments, prescriptions, referrals, and follow-up care.

Depending on the plan being considered, verify the rules that affect the care your parent is most likely to use. These may include provider networks, referrals, prior authorization, prescription requirements, pharmacy arrangements, geographic coverage, and other plan-specific conditions.

You do not need to understand every rule in Medicare. You need to understand the rules attached to the care your parent is actually likely to use.

7. Be especially careful if switching to Original Medicare

During Medicare Open Enrollment, an eligible person can switch from a Medicare Advantage Plan to Original Medicare.

But that does not mean the person will automatically be able to purchase any Medicare Supplement Insurance, or Medigap, policy they want afterward.

Verify Medigap rights before finalizing the switch. Federal Medigap Open Enrollment is generally a one-time six-month period, not an annual enrollment period. Outside that period, the ability to buy or change a Medigap policy may depend on guaranteed-issue rights, individual circumstances, insurer underwriting where permitted, and state protections.

If Medigap is part of the decision, verify the person's rights and timing before completing the change. Medicare, the appropriate State Health Insurance Assistance Program, and the relevant state insurance authority can help clarify the rules that apply.

8. Get unbiased help when the comparison is not clear

Family caregivers do not have to make a Medicare comparison alone.

State Health Insurance Assistance Programs, commonly called SHIPs, provide local, one-on-one Medicare counseling and assistance to Medicare-eligible people, their families, and caregivers. SHIP assistance is provided at no charge to consumers and is designed to be objective rather than tied to the sale of a specific plan.

SHIP programs can help with Medicare enrollment, coverage changes during Open Enrollment, plan comparison, out-of-pocket cost questions, Medicare rights, and how Medicare coordinates with other insurance.

When asking for help, bring the same information you would use for your own comparison: current coverage, medication list, pharmacies, important doctors, relevant care needs, and the questions created by the Annual Notice of Change.

9. Confirm the final decision before December 7

Do not let several weeks of research end with an unfinished enrollment task.

  • We decided whether to keep or change the current coverage.
  • We reviewed the Annual Notice of Change.
  • We compared current prescriptions and pharmacy needs.
  • We checked important doctors and facilities.
  • We compared costs beyond the monthly premium.
  • We checked the plan rules that matter to the care actually used.
  • We verified Medigap implications separately if a switch to Original Medicare is being considered.
  • We completed any required enrollment action by December 7.
  • We kept confirmation or documentation of the final enrollment decision.

The one-page caregiver check before you choose

If you want the shortest possible version, work through this list before the final decision.

  • I have the current Medicare and plan information.
  • I read the Annual Notice of Change.
  • I know what changes next year if the current plan is kept.
  • I have one current prescription medication list.
  • I checked those medications in the plans being compared.
  • I checked the pharmacy my parent normally uses.
  • I checked the doctors and specialists my parent depends on.
  • I checked relevant hospitals or facilities.
  • I compared more than the monthly premium.
  • I considered what changed in my parent's care during the past year.
  • I checked relevant network, referral, authorization, and geographic rules.
  • I verified Medigap implications if a switch to Original Medicare is being considered.
  • I asked for objective help if important questions remain unresolved.
  • I recorded the final decision and any enrollment confirmation.

What if your parent wants to keep the same plan?

Keeping the same plan can be a reasonable decision.

If the coverage is still available and continues to fit your parent's needs, there may be no reason to change simply because Open Enrollment has arrived.

The important step is the review.

A familiar plan can still change from one year to the next. Your parent's prescriptions, doctors, pharmacy, finances, location, or health-care use may also have changed.

“We are keeping the same plan” is a much stronger decision after you have checked the next year's information than before.

Remember whose decision this is

A family caregiver may do most of the information gathering, but being someone's son, daughter, spouse, or caregiver does not automatically create authority to make every insurance or health-care decision for another adult.

When your parent can participate, involve them in the comparison and final choice. If you need to communicate with Medicare, an insurer, or another organization on their behalf, verify the authorization or representative process that applies.

The caregiver's most useful role is often to make the decision easier to see: gather the documents, keep the medication and provider lists current, write down the questions, verify the answers, and keep a record of the final choice.

There is no single “best Medicare plan” for every parent

The useful question is more specific:

Which available coverage best fits this person's current prescriptions, doctors, expected care, location, preferences, and financial situation under the rules that actually apply to them?

That is why a caregiver checklist helps. It converts a large insurance decision into a series of smaller questions that can be verified one at a time.

You do not need to remember every Medicare rule. You need to know what information matters, what changed, what still needs verification, and where to get an authoritative answer.

Keep the bigger care plan visible

Do not let Medicare become another decision you carry only in your head

If insurance is only one part of a growing caregiving load, organize the other pieces before they become urgent too. A simple long-term care plan can help your family separate current needs, future options, responsibilities, facts that still need verification, and the changes that should trigger a review.
