Do Medicare Advantage Plan Benefits Change Every Year?

Posted on October 18th, 2026

ㅤ

If you already have a Medicare Advantage plan, you may wonder whether your coverage will stay the same next year. The answer is that Medicare Advantage plan costs, benefits, provider networks, and coverage rules can change from year to year.

Even if you are happy with your current coverage, reviewing your plan annually is important. A change to your prescription coverage, preferred doctor, or out of pocket expenses could affect whether your current plan remains the right choice.

Health Wealth Protect LLC helps Medicare beneficiaries understand these changes and compare available coverage options.

Why Do Medicare Advantage Plans Change Annually?

Medicare Advantage plans are offered by private insurance companies that contract with Medicare. Plans must follow Medicare requirements, but their specific benefits, costs, and service arrangements can vary.

Insurers may update their plan offerings for a new coverage year. A plan may change its monthly premium, cost sharing, prescription drug formulary, provider network, or supplemental benefits.

Your plan may also change its name, contract, or availability in your area. Review the official notices from your insurer rather than assuming that last year's information still applies.

6 Things to Review Before the New Plan Year

1. Monthly Premiums and Deductibles

Check whether your monthly plan premium or applicable deductibles will change. Also remember to account for your Medicare Part B premium.

A plan with a low premium may still have significant copayments or other out of pocket expenses when you need care.

2. Copayments and Coinsurance

Your costs for doctor visits, specialist appointments, diagnostic tests, hospital stays, and other covered services may change.

Review the plan's Evidence of Coverage to understand what you may pay for the services you use most frequently.

3. Prescription Drug Coverage

A plan may change its formulary, drug tiers, pharmacy arrangements, or coverage restrictions.

Make a current list of your medications and compare it with the upcoming year's drug coverage. Check whether your preferred pharmacy participates in the plan and whether prior authorization or other restrictions apply.

4. Doctors, Hospitals, and Provider Networks

Provider networks can change. Your doctor or specialist may no longer participate in your plan for the next year.

Contact your providers and the insurance company to verify participation for the new plan year. Do not rely solely on an old provider directory.

5. Additional Benefits

Some Medicare Advantage plans offer benefits such as dental services, vision care, hearing benefits, fitness programs, or certain supplemental allowances.

The scope, annual limits, participating providers, and eligibility conditions for these benefits may change. Read the new plan documents carefully.

6. Annual Out of Pocket Maximum

Review the plan's maximum amount you may have to pay for covered Part A and Part B services during the year.

This limit is an important part of comparing financial exposure between plans. Prescription drug costs are handled separately under applicable Part D rules and should also be evaluated.

ㅤ

What Is the Annual Notice of Change?

Your insurer generally sends an Annual Notice of Change outlining significant changes to your plan for the upcoming year.

Read this notice alongside the plan's updated Evidence of Coverage. These documents help explain changes to premiums, benefits, cost sharing, networks, and coverage rules.

If you are unsure how a change affects you, contact your insurer or a licensed insurance professional before making a decision.

When Should You Review Your Medicare Advantage Plan?

The Annual Enrollment Period runs from October 15 through December 7. During this period, eligible beneficiaries can review their options and make permitted changes for coverage beginning January 1.

If you are already enrolled in Medicare Advantage, you may also have an opportunity to make a permitted change during the Medicare Advantage Open Enrollment Period from January 1 through March 31.

Other enrollment opportunities may apply in certain circumstances. Confirm the rules that apply to your situation.

Frequently Asked Questions

Do I have to change my Medicare Advantage plan every year?

No. You can generally keep your plan if it remains available and you remain eligible. Reviewing the new plan documents helps you decide whether keeping it makes sense.

Can my doctor leave my plan's network?

Yes. Provider participation can change. Verify your doctor's network status for the upcoming coverage year.

What if my prescription is no longer covered?

Review the plan's current drug coverage rules and discuss alternatives with your prescriber or insurer. Depending on your circumstances, you may also wish to compare other available plans during an applicable enrollment period.

When do changes to next year's coverage usually take effect?

Changes made during the Annual Enrollment Period generally take effect January 1 of the following year.
