Medicare AEP 2027 Key Changes You Need to Know

Medicare’s Annual Enrollment Period is open—and this is not a “set it and forget it” year.

Even if you like your current plan, it deserves a fresh look. Medicare Advantage and Part D plans can change their costs, provider networks, prescription coverage and supplemental benefits every year. A plan that worked well for you in 2026 may still be your best choice for 2027—but let’s make sure.

Annual Enrollment runs from October 15 through December 7. Changes made during this period generally take effect on January 1, 2027. You can change Medicare Advantage or Part D plans, move between Original Medicare and Medicare Advantage, or return to Original Medicare and select separate prescription coverage. medicare.gov

Start With What Matters to You

The biggest mistake people make is looking only at the monthly premium.

A $0-premium plan may still cost more over the year if your doctor leaves the network, a medication moves to a higher tier or your hospital copay increases. Extra benefits are nice—but they should not distract you from the coverage you rely on most.

Your review should begin with a few practical questions:

• Are your doctors, specialists and preferred hospitals still in the network?

• Are your prescriptions still covered—and at what cost?

• Have your copays, deductibles or maximum out-of-pocket limit changed?

• Is your pharmacy still preferred?

• Have dental, vision, hearing, transportation or over-the-counter benefits changed?

• Will you need prior authorization for services or medications you regularly use?

You do not necessarily need to change plans. You simply need to know what is changing before you decide to stay.

Prescription Costs Are a Major 2027 Change

For 2027, the standard Part D deductible increases from $615 to $700, although individual plans may structure their deductibles differently.

The annual out-of-pocket limit for covered Part D medications also increases from $2,100 in 2026 to $2,400 in 2027. Once you reach that limit, you pay nothing for covered Part D drugs for the remainder of the year. cms.gov

That makes your medication list one of the most important parts of an annual review. A drug plan can change:

• Its formulary

• Drug tiers

• Prior-authorization requirements

• Step-therapy rules

• Preferred pharmacies

• Mail-order pricing

• The way its deductible applies

Before reviewing plans, gather the exact name and dosage of each medication, how often it is filled and which pharmacy you prefer.

One medication moving to a different tier can make a meaningful difference in your yearly costs.

Medicare Advantage Benefits May Change

Medicare Advantage plans must cover medically necessary services covered by Original Medicare, but their networks, copays, authorization requirements and supplemental benefits can vary. medicare.gov

For 2027, look carefully at changes involving:

• Specialist and hospital copays

• Maximum out-of-pocket limits

• Dental allowances and participating dentists

• Hearing-aid coverage

• Vision benefits

• Over-the-counter allowances

• Transportation and meal benefits

• Prior authorization

• Provider and hospital networks

Do not compare plans based only on the largest dental allowance or OTC benefit.

A generous dental benefit is not especially valuable if your dentist does not accept the plan—or if the services you need are limited or excluded. The same is true of hearing, vision and transportation benefits. The headline number does not always tell the whole story.

Prior Authorization Deserves a Closer Look

Prior authorization may be required for imaging, surgery, rehabilitation, skilled nursing care, home health services, specialty medications and other treatments.

This is especially important if you receive ongoing physical therapy, injections, infusions, imaging or specialist care.

The question is not simply whether a plan uses prior authorization. Most plans use it in some form. The better question is whether its requirements are likely to affect the care you expect to use.

Compare the Whole Plan—not Just the Premium

Before comparing plans, create a simple snapshot of your current needs:

• Doctors and specialists

• Preferred hospitals and medical groups

• Prescription medications

• Preferred pharmacy

• Expected procedures, therapies or treatments

• Dental, hearing and vision needs

• Travel or time spent outside your plan’s service area

• Monthly budget

• Comfort with unexpected medical expenses

Then compare the total picture:

• Monthly premium

• Medical and drug deductibles

• Primary-care and specialist copays

• Hospital and outpatient costs

• Prescription costs

• Maximum out-of-pocket exposure

• Provider access

• Supplemental benefits you will actually use

The best plan is not necessarily the one with the lowest premium or the longest list of extras. It is the one that works with your healthcare needs and budget.

Confirm Your Providers Carefully

Provider directories are helpful, but they can sometimes be incomplete or outdated.

Before enrolling, confirm that your providers accept the exact 2027 plan—not simply the insurance company.

Ask:

• Is my doctor accepting this specific 2027 plan?

• Is the medical group in the network?

• Is my preferred hospital included?

• Will I need referrals to see specialists?

• Does the plan provide appropriate coverage when I travel?

When possible, confirm network participation with both the insurance company and the provider’s office.

Review the Documents Your Plan Sent You

If you already have a Medicare Advantage or Part D plan, your Annual Notice of Change explains what will be different in 2027.

Also review the:

• Summary of Benefits for common costs and benefits

• Evidence of Coverage for detailed plan rules

• Drug formulary for medication coverage, tiers and restrictions

• Provider directory for doctors, hospitals and other providers

Do not rely only on television commercials, postcards or benefit highlights. Those materials may introduce a plan, but they rarely show the full cost and coverage picture.

Should You Change Plans?

Changing may make sense if:

• A doctor or hospital leaves the network.

• A medication becomes more expensive or is no longer covered.

• Copays, deductibles or maximum out-of-pocket exposure increase.

• New restrictions could affect your care.

• Important supplemental benefits are reduced.

• Another plan better matches your actual needs.

• Your current plan will not be offered in 2027.

Staying may make sense if:

• Your providers remain in the network.

• Your medications remain covered at manageable costs.

• The plan has worked well when you needed care.

• Its supplemental benefits are useful and accessible.

• Its total expected cost remains competitive.

• Its rules continue to fit your healthcare needs.

There is no prize for changing plans—and no prize for staying. The goal is to make an informed decision.

Let’s Review Your Coverage

Medicare changes every year, but reviewing your plan does not have to be overwhelming.

We’ll start with your doctors, prescriptions and healthcare priorities. Then we’ll compare costs, coverage and the benefits you are most likely to use.

If your current plan still fits, I’ll tell you that too.

The deadline to make most changes is December 7, and new coverage begins January 1, 2027. A careful review now can help prevent expensive or frustrating surprises later.
