Key facts

• Your Medigap Open Enrollment Period lasts 6 months. It starts the first month you have Part B and are 65 or older.
• During that window, insurers generally can't deny you or charge more because of health problems.
• The 2026 Part A hospital deductible is $1,736 per benefit period. The 2026 Part B deductible is $283.
• The 2026 standard Part B premium is $202.90 a month, and you pay it in addition to any Medigap premium.
• Medigap works only with Original Medicare. It can't pay Medicare Advantage costs.
• Medigap policies sold today don't include drug coverage. Drug coverage comes from Part D or other creditable coverage.
• Each Medigap policy covers one person. Spouses buy their own.
• Figures shown are for 2026 and change every year.

What does a Medicare Supplement do for a veteran?

A Medicare Supplement helps pay some of the costs Original Medicare doesn't, like deductibles, coinsurance, and copays, when you get care outside the VA. For veterans, it can turn Original Medicare into a fuller backup for the doctors, hospitals, and emergencies the VA doesn't cover, depending on the policy you choose.

Original Medicare pays a big share of covered care, but not all of it. In 2026, the Part A deductible is $1,736 for each hospital benefit period, and the Part B deductible is $283 a year. After the Part B deductible, you generally pay 20% coinsurance for most covered services, with no yearly cap under Original Medicare alone. Medigap is private insurance designed to help with those leftover costs.

Here's why that matters to veterans. VA health care generally covers care at VA facilities or care the VA authorizes. A heart attack on a road trip, a specialist near your daughter's house, a local hospital closer than the nearest VA: those can fall outside the VA. With Original Medicare, you can generally use any doctor or hospital in the U.S. that takes Medicare. Medigap helps cover what Medicare leaves behind there.

That's the gap Veteran Savings Network helps veterans spot and close. Book a free call and a licensed agent will walk you through it.

Is Medigap worth it if you have VA health care?

For many veterans, it comes down to how much care you expect to get outside the VA. If you rely almost entirely on the VA, Medigap may add less. If you want freedom to use non-VA doctors and hospitals, travel often, or live far from a VA facility, it can fill meaningful gaps.

VA and Medicare don't coordinate. VA doesn't bill Medicare, so they won't split the same bill. The VA may bill Medicare supplemental insurance for covered non-service-connected care, but that's between the VA and the insurer. Medigap's real job for a veteran is covering your share when you use Medicare outside the VA.

Some questions that help frame it:

• How far is your nearest VA facility, and how long are the waits where you live?
• Do you have non-VA doctors you want to keep seeing?
• Do you travel, spend winters elsewhere, or visit family out of state?
• Would a large hospital bill outside the VA be a financial problem?
• Do you have TRICARE For Life, CHAMPVA, or retiree coverage that already fills these gaps?

There's no one right answer, and we don't push one plan over another. Our licensed agents can show you the options in your area and the tradeoffs in plain English. Talk it through with us.

What does Medigap cover, and what doesn't it cover?

Medigap helps pay Original Medicare's cost sharing, like deductibles and coinsurance, depending on the standardized plan. Many plans include foreign travel emergency coverage up to plan limits. Medigap generally doesn't cover dental, vision, hearing aids, glasses, long-term care, or prescription drugs, so those gaps need another answer.

Because Medigap doesn't cover dental, vision, or hearing, some veterans look at other ways to fill those specific gaps. That's part of what our licensed agents help sort out on a free call.

Do you need a Medicare Supplement if you have TRICARE For Life?

In most cases, Medigap is redundant with TRICARE For Life. TFL works with Original Medicare: Medicare pays first, and TRICARE pays second. When both cover a service, TRICARE says you generally won't pay anything out of pocket. Paying a Medigap premium in addition to that usually adds little.

TRICARE For Life requires Part A and Part B. Once you have both, TFL coverage is automatic. TRICARE's own handbook describes Medigap as optional and advises beneficiaries to carefully evaluate their needs before keeping a supplement. For most TFL beneficiaries, the math rarely favors paying for both.

There are edge cases, like services Medicare covers that TRICARE doesn't, so it's worth a conversation before you drop or buy anything. Our TRICARE For Life and Medicare guide goes deeper, and our licensed agents can walk through your exact setup. Book a free call.

When is the Medigap Open Enrollment Period?

Your Medigap Open Enrollment Period is a one-time, 6-month window that starts the first month you have Part B and are 65 or older. During it, insurers generally can't deny you a policy or charge more because of health problems. After it ends, that protection generally goes away.

This is the window that matters most, and it doesn't come back each year. If you start Part B at 65, your Medigap Open Enrollment Period starts then. If you delay Part B because you have qualifying job-based coverage, it starts when your Part B starts.

Outside that window, in most states, an insurer can ask health questions and may deny you or charge more, unless you have a guaranteed issue right. Some states have extra protections, so check with your State Insurance Department. Federal law also generally doesn't require insurers to sell Medigap to people under 65, though some states do.

Many veterans don't realize this window is ticking once Part B starts. If you're close to 65 or just started Part B, talk with a licensed agent before it closes.

What are Medigap guaranteed issue rights?

Guaranteed issue rights are situations where an insurer generally must sell you certain Medigap policies, can't deny you for health problems, and can't charge more for them, even outside your open enrollment window. They usually apply when other coverage ends through no fault of your own.

Medicare lists situations like these, generally:

• Your Medicare Advantage plan leaves Medicare, stops serving your area, or you move out of its service area.
• Employer, retiree, COBRA, or union coverage that pays after Medicare ends.
• Your Medigap insurer goes bankrupt or your policy ends through no fault of your own.
• You leave a Medicare Advantage plan or drop Medigap because the company broke the rules or misled you.

Trial rights

Medicare also has trial rights. If you joined a Medicare Advantage plan when first eligible at 65, you can generally switch to Original Medicare and buy a Medigap policy within your first year. If you dropped Medigap to join a Medicare Advantage plan for the first time, you can generally get your old policy back, or a comparable one, if you leave within the first 12 months.

The rules have conditions and time limits. A licensed agent can help you check whether one applies to you.

Medigap vs Medicare Advantage: which fits veterans?

Medigap with Original Medicare generally means more freedom to see any provider that takes Medicare, usually with a higher monthly premium. Medicare Advantage generally means a network, copays, a yearly out-of-pocket limit, and extras some plans may include. Neither is right for everyone, and VA care works alongside either one.

That last row is the one veterans most often miss. Leaving Medigap for a Medicare Advantage plan is generally easy. Coming back can be hard if you're past your guaranteed windows. Read more in our Medicare Advantage for veterans guide, and a licensed agent at Veteran Savings Network can check what's available where you live.

How does drug coverage work with a Medicare Supplement for veterans?

Medigap policies sold today don't include drug coverage. Veterans who use Medigap generally rely on VA pharmacy coverage, a separate Part D plan, or other creditable coverage like TRICARE. VA drug coverage generally counts as creditable, which helps avoid the Part D late enrollment penalty if you rely on it.

The Part D late enrollment penalty is 1% of the national base beneficiary premium for each full month you went without Part D or creditable coverage. In 2026, that base premium is $38.99. The penalty generally lasts as long as you have Medicare drug coverage. The VA notes you can join Part D within 63 days of losing VA health care or other creditable drug coverage without that penalty.

One thing to plan for: the VA pharmacy generally fills prescriptions from VA providers. If you see a non-VA doctor through Medicare and get a prescription, how it gets filled is worth thinking through ahead of time. Our licensed agents can lay out the options.

Common mistakes we see with Medigap for veterans

The mistakes we see most are missing the one-time Medigap Open Enrollment Period, paying for Medigap alongside TRICARE For Life without checking, dropping Part B, assuming Medigap covers dental or drugs, and assuming a spouse is covered under the veteran's policy. Each one can be avoided with a little planning.

• Waiting too long. After your 6-month Medigap Open Enrollment Period, health questions may apply in most states.
• Doubling up with TFL. TRICARE For Life generally already pays what Medicare doesn't.
• Dropping Part B. Medigap requires Original Medicare. If you cancel Part B, the VA notes you generally can't get it back until the following January, and a penalty may apply.
• Expecting dental, vision, or drugs. Medigap generally doesn't cover these.
• Forgetting the spouse. Each Medigap policy covers one person, and VA care generally doesn't cover spouses.
• Switching without a way back. Leaving Medigap for a Medicare Advantage plan can be hard to undo after trial rights end.

Every one of these is easy to avoid with a second set of eyes. That's what we're here for.

What should veterans do next? Step by step

Start by confirming your Part A and Part B dates, since your Medigap window starts with Part B at 65 or older. Then list your other coverage, the non-VA care you expect, and how you'll handle drugs. Compare Medigap and Medicare Advantage side by side with a licensed agent before the window closes.

• Confirm your Part B start date. That's when your 6-month Medigap Open Enrollment Period generally starts, if you're 65 or older.
• List your other coverage: VA, TRICARE For Life, CHAMPVA, employer, or retiree coverage.
• Think through where you'll get care outside the VA, including travel.
• Decide how you'll handle drug coverage: VA pharmacy, Part D, or other creditable coverage.
• Compare Original Medicare plus Medigap with Medicare Advantage in your area.
• Plan separately for your spouse's coverage.
• Talk it through with a licensed agent before you decide.
