Switching from Medicare Advantage Back to a Supplement (Medigap)

What you need to know before making the move in 2026
Many people start out in a Medicare Advantage plan because the low premiums and extra perks look attractive. But after a few years, some realize they’d rather have the freedom and predictability of Original Medicare plus a Supplement (Medigap) policy.
If you’ve been thinking about switching back, here’s what you should know.
It’s common for beneficiaries to re-think their choice after a few years. Some reasons include:
  • Network frustrations — doctors or hospitals you want aren’t covered.
  • Prior authorizations —needing plan approval for tests, procedures, or even prescriptions.
  • High out-of-pocket costs — Advantage plans cap expenses, but the MOOP in 2026 is still $9,250

    A bad health year can make costs add up quickly.
  • Benefit changes — Advantage plans can change coverage, networks, or drug formularies every year.
  • Desire for stability — Supplements don’t change benefits annually, and you can see any doctor who accepts Medicare.

Why People Consider Leaving Medicare Advantage

Know Your State

One of the most important factors in switching back to a Supplement is where you live .
  • Some states (like New York, Connecticut, and a few others) have guaranteed issue protections — meaning you can apply for a Supplement at any time without answering health questions. In those states, the transition from Advantage back to Medigap is much easier.
  • Most states however, require medical underwriting if you apply for a Supplement outside your initial enrollment period or without a special right. This means the insurance company can:
    • Ask about your health history
    • Charge higher premiums
    • Exclude coverage for certain conditions
    • Or, in some cases, decline your application

Exceptions to Know:

  • If you’re in your first year of trying a Medicare Advantage plan , you have a “trial right” to switch back to Original Medicare and buy a Supplement without underwriting.
  • A few states have special rules, such as limited open enrollment windows each year where underwriting is waived.
Bottom line: Before switching, know your state’s rules. In guaranteed issue states, your options are wide open. In others, health conditions may limit your choices or make premiums higher.

Steps to Take If You’re Considering Switching

  1. Check your eligibility — Find out if you qualify for a guaranteed issue right in your state.
  2. Apply for a Supplement before dropping Advantage — Don’t leave your plan until you’re approved.
  3. Compare Supplement options — Plan G and High Deductible G are the most popular in 2026, with Plan N also growing in interest.
  4. Review prescription coverage — If you leave Advantage, you’ll need to add a stand-alone Part D drug plan.

Costs to Keep in Mind

  • Medicare Advantage: Often $0–$50/month premiums, but with cost-sharing for services and a cap at $9,250 in 2026.
  • Medigap + Part D: Higher monthly premiums, but much lower out-of-pocket costs when you need care.
Example: Someone with frequent specialist visits and a hospitalization may find Medigap’s higher premiums worth it because their out-of-pocket costs are nearly eliminated.

Key Takeaway

Switching from Medicare Advantage back to a Supplement can be the right move if you want stability, nationwide access, and predictable costs. But it’s not always easy — medical underwriting and state rules matter.
Before making a move, the safest step is to talk with your broker. They can check your eligibility, review plan costs, and guide you through the application process so you don’t lose coverage.

Part D Stand-Alone vs. Medicare Advantage Drug Coverage

Which option makes more sense in 2026?
Prescription drug costs are one of the biggest concerns for Medicare beneficiaries. You have two main ways to get drug coverage:
  • A stand-alone Part D plan (used with Original Medicare, with or without a Supplement)
  • Prescription drug coverage bundled into a Medicare Advantage plan (MAPD)
At first glance, they may look similar, but there are important differences. Let’s break it down.

Stand-Alone Part D (With Original Medicare)

If you stay with Original Medicare, you’ll likely need to buy a separate Part D plan for prescriptions.

What You Pay in 2026

  • Deductible: Up to $615 (up from $590 in 2025)
    MEDICARE COST SHARE 2026
  • Out-of-Pocket Cap: $2,100 annually for covered drugs (slightly higher than 2025’s $2,000)
    MEDICARE COST SHARE 2026
  • Average Premium: $34.50/month, down from $38.31 in 2025
    MEDICARE COST SHARE 2026
  • Insulin: No more than $35/month (or 25% of negotiated price, whichever is less)
    MEDICARE COST SHARE 2026

Pros

  • Freedom to pair with any doctor coverage. Works alongside Medigap for broad provider access.
  • Flexibility in choosing your drug plan. You can select based on your prescriptions and preferred pharmacies.

Cons

  • Separate policy to manage. You’ll have Medicare + Supplement + Part D, which can be three different bills.
  • May cost more than Advantage drug coverage.Depending on your meds, premiums plus copays can add up.

Choosing the Right Medicare Coverage

Selecting the best Medicare coverage depends on factors like your healthcare needs, budget, and preferred providers. You can choose between:
  • Original Medicare (Parts A & B): Allows you to see any doctor or
    hospital that accepts Medicare but does not include prescription drug
    coverage (Part D) or additional benefits.
  • Medicare Advantage (Part C): Offers bundled coverage with
    potential extra benefits but may require using a network of providers.
  • Medigap (Medicare Supplement Insurance): Helps cover
    out-of-pocket costs not covered by Original Medicare, such as
    copayments and deductibles.

Key Medicare Enrollment Periods

It is crucial to enroll in Medicare at the right time to avoid penalties and ensure continuous coverage:
  • Initial Enrollment Period (IEP): A seven-month window starting
    three months before your 65th birthday month.
  • General Enrollment Period (GEP): From January 1 to March 31
    each year for those who missed their IEP.
  • Annual Election Period (AEP): From October 15 to December 7,
    allowing you to switch or enroll in Medicare Advantage and Part D
    plans.
  • Open Enrollment Period(OEP): From January 1 to March 31 for
    those who missed AEP and want to make certain changes.
  • Special Enrollment Period(SEP): Can be used anytime during the
    calendar year for those that meet certain criteria such as moving to a
    new service area.

Finding Help with Medicare

Understanding Medicare can be complex, but you don’t have to do it alone. Licensed Insurance Brokers, Medicare.gov, and state health assistance programs can provide guidance tailored to your specific needs.
By taking the time to explore your Medicare options, you can make informed decisions that ensure you receive the healthcare coverage that best suits your lifestyle and budget.
Do I have to sign up for Medicare?
It depends upon your current coverage. If you are employed and your employer has over 20 employees then you can delay signing up for Medicare and avoid penalties.
No, You will have to enroll in a stand alone Part D plan or a Medicare Advantage Plan(Part C) to get coverage.
There are no networks with Medicare and most doctors and hospitals accept it. However, Medicare does not cover 100% of services so a Medicare Supplement or Medicare Advantage plans is advisable.
