Medicare gives you a strong foundation for healthcare coverage, but Original Medicare does not pay every cost. In 2026, you may still face premiums, deductibles, coinsurance, and other out-of-pocket expenses. That is where Medicare Supplement Insurance: better known as Medigap: can help.
Medigap plans work alongside Original Medicare to help pay certain costs that Medicare Parts A and B leave behind. This can make your healthcare expenses more predictable and support greater financial stability.
This guide explains how Medigap works in 2026, compares Plan G and Plan N, reviews important Medicare Advantage updates, and walks you through enrollment step by step. Super Senior Services helps Medicare beneficiaries in Florida, Georgia, Texas, Tennessee, North Carolina, South Carolina, Virginia, and New York State compare coverage with confidence.
Why Original Medicare Has “Gaps” in 2026
Original Medicare includes Part A hospital insurance and Part B medical insurance. However, it does not have a yearly limit on your out-of-pocket costs unless you have supplemental coverage, such as Medigap.
For 2026, the standard Part B premium is $202.90 per month, and the annual Part B deductible is $283. After meeting the deductible, you typically pay 20% coinsurance for Medicare-approved Part B services.
Hospital expenses can also add up. The Part A inpatient hospital deductible is $1,736 per benefit period in 2026: not necessarily once per calendar year. A benefit period can restart after you have been out of the hospital or skilled nursing facility for 60 consecutive days.
As Medicare explains, “There’s no yearly limit on what you pay out of pocket if you have Original Medicare” unless you have supplemental coverage. A Medigap plan can help reduce those unpredictable bills by paying some or all of eligible deductibles, coinsurance, and copayments.
What Medigap Covers: and What It Does Not
Medigap policies are sold by private insurance companies, but the benefits are standardized by letter in most states. This means a Plan G from one company provides the same standardized medical benefits as Plan G from another company. Premiums, customer service, and underwriting practices can still vary.
Medigap generally helps with:
- Part A hospital coinsurance and eligible hospital costs
- Part B coinsurance or copayments
- Part A deductibles, depending on the plan
- Skilled nursing facility coinsurance
- The first three pints of blood
- Certain foreign travel emergency costs, depending on the plan
Medigap generally does not cover:
- Medicare Part B premiums
- Prescription drug coverage
- Routine dental, vision, or hearing services
- Hearing aids
- Long-term custodial care
- Medicare Advantage copayments or deductibles
You also cannot use Medigap and Medicare Advantage together for the same coverage. If you enroll in Medicare Advantage, you generally should not continue paying for a Medigap policy unless you are carefully using a qualifying trial right or transition period.
Plan G vs. Plan N: Two Popular 2026 Options
Medigap Plan G
Plan G is often chosen by people who want broad protection from Original Medicare cost sharing. It generally pays:
- Part A deductible
- Part A and Part B coinsurance
- Part B excess charges, where permitted
- Skilled nursing facility coinsurance
- Foreign travel emergency benefits up to plan limits
Plan G does not pay the annual Part B deductible. In 2026, that means you pay the first $283 in eligible Part B expenses before Plan G begins paying its share.
The practical benefit is predictability. After you meet the Part B deductible, your eligible Medicare-approved medical expenses may be much easier to budget.
Medigap Plan N
Plan N may offer a lower monthly premium than Plan G, but it requires more cost sharing. You may pay:
- Up to a $20 copayment for certain office visits
- Up to a $50 copayment for emergency room visits when you are not admitted
- Part B excess charges, if applicable
Plan N can be a reasonable fit if you are comfortable with occasional copayments and your doctors accept Medicare assignment. Plan G may be more attractive if you prefer fewer surprise bills or see physicians frequently.
The right choice depends on your healthcare needs, budget, provider relationships, and eligibility rules. A licensed advisor can compare the total cost: not just the monthly premium.
Your Six-Month Medigap Open Enrollment Period
Your federal Medigap Open Enrollment Period is a one-time six-month window. It begins when you are at least 65 and enrolled in Medicare Part B.
During this period:
- You can generally buy any Medigap plan sold in your state.
- An insurer cannot deny you because of pre-existing health conditions.
- The insurer generally cannot use medical underwriting to charge you more based on your health.
- You have more plan choices and stronger enrollment protections.
Medicare states, “The best time to buy a Medigap policy is during your Medigap Open Enrollment Period.”
This period does not repeat every year like Medicare’s October 15–December 7 Annual Enrollment Period. Waiting can mean higher premiums, fewer choices, or a medical underwriting review.
2026 Plan N and Switching Changes
In most states, including Florida, Georgia, Texas, Tennessee, North Carolina, South Carolina, and Virginia, 2026 changes are affecting how Plan N is handled in certain guaranteed issue situations.
Beginning April 9, 2026, industry guidance indicates that Plan N may no longer be available in many federal guaranteed issue situations in most states. In those circumstances, beneficiaries may need to choose from other federally protected plans, such as Plan G, instead.
Additionally, switching from one Medigap plan to another outside your initial six-month enrollment period or a qualifying guaranteed issue event may require medical underwriting. An insurer could ask health questions, charge a higher premium, or decline an application.
These rules can depend on your state, the reason you are changing coverage, and the carrier’s current procedures. Review the federal guidance at Medicare.gov and work with a licensed advisor before canceling existing coverage.
New York State Is Different
New York State has some of the strongest Medigap consumer protections in the country. Under New York rules, Medigap policies generally have:
- Year-round guaranteed issue
- No medical underwriting for eligible applicants
- Pure community rating, meaning premiums are not based on your age or health status
In practical terms, a New York resident with Medicare Parts A and B can generally apply for or switch Medigap plans throughout the year, including Plan N, without being declined because of health history. The 2026 Plan N restrictions affecting many federal guaranteed issue situations do not apply in the same way in New York.
Premiums can still vary by plan, insurance company, and geographic area. You can review New York’s official Medigap information through the New York Department of Financial Services.
Medicare Advantage Updates You Should Know in 2026
Medigap is not the only Medicare option. Medicare Advantage provides another way to receive Part A and Part B benefits through a Medicare-approved private plan.
In 2026:
- The average Medicare Advantage plan premium is approximately $14 per month, while some enrollee-weighted estimates for Medicare Advantage plans with prescription coverage are closer to $15.
- The maximum in-network out-of-pocket limit for covered Part A and Part B services can be as high as $9,250. Individual plans may set a lower limit.
- Most Medicare Advantage plans include Part D prescription drug coverage.
- Networks, formularies, referrals, and prior authorization requirements can vary by plan.
Medicare Advantage plans may also offer dental, vision, hearing, fitness, transportation, or other supplemental benefits. However, you usually need to use the plan’s network for routine care, and your costs may be higher outside the network.
For prescription coverage in 2026, the Part D out-of-pocket cap is $2,100. Once you reach that limit for covered Part D drugs, you pay $0 for covered prescriptions for the rest of the calendar year. Covered insulin is capped at $35 per month, and ACIP-recommended adult vaccines generally have $0 cost-sharing under Part D.
These updates can improve affordability, but your actual savings depend on your prescriptions, pharmacy, plan formulary, providers, and healthcare needs.
How to Enroll: A Step-by-Step Medicare Plan Guide
1. Confirm your Medicare eligibility and timing
Your Initial Enrollment Period generally begins three months before the month you turn 65, includes your birthday month, and ends three months afterward.
If you are still working and have group health coverage based on current employment, you may qualify for a Special Enrollment Period. Confirm the rules before delaying Part B.
2. Enroll in Medicare Parts A and B
If you are not automatically enrolled, apply through Social Security. You generally need both Part A and Part B before purchasing Medigap.
3. Compare Original Medicare plus Medigap with Medicare Advantage
Consider:
- Your doctors and hospitals
- Prescription medications and formularies
- Monthly premiums
- Deductibles and coinsurance
- Provider networks
- Travel needs
- Dental, vision, and hearing benefits
- Your comfort with medical underwriting
4. Protect your Medigap Open Enrollment Period
If you choose Original Medicare, begin comparing Medigap plans as soon as your Part B coverage starts. Do not assume you can obtain the same plan later without underwriting.
5. Add prescription drug coverage
Medigap does not include Part D. You may need a separate Part D plan. If you go 63 days or longer without creditable prescription drug coverage: coverage expected to pay at least as much as standard Medicare drug coverage: you may face a permanent late enrollment penalty.
6. Review your coverage each year
Medicare Advantage and Part D plans can change premiums, formularies, networks, and cost sharing. The Annual Enrollment Period runs from October 15 through December 7, 2026, for coverage changes effective January 1, 2027.
A yearly benefit review helps ensure your coverage continues to support your health and budget.
