Medigap Under 65: Can You Buy It in Your State? (2026–2027)
Bottom Line
Medigap access before 65 depends on your state's protections; federal law doesn't require insurers to sell it to you. Check which plans are guaranteed, your application window, and actual under-65 premiums before comparing insurers.
If you qualify for Medicare before 65 because of a disability or ESRD, whether you can buy a Medigap (Medicare Supplement) policy depends almost entirely on where you live. Federal law does not require insurance companies to sell Medigap policies to anyone under 65, so in many states you may not be able to buy the policy you want — or any policy — until you turn 65. Several states, however, guarantee under-65 access by state law. Checking your own state’s rules is the first step, before comparing plan letters or prices.
If you also own a business and are weighing an SBA loan, life insurance for an SBA loan is a separate financing topic to discuss with your lender. It has no role in Medicare enrollment or Medigap eligibility.
Why Under-65 Medigap Is Different
Medigap is private insurance that helps pay your share of costs in Original Medicare — copayments, coinsurance, and deductibles. You generally must have both Part A and Part B to buy one, and it only works alongside Original Medicare, not a Medicare Advantage plan.
The standard guaranteed-access window — the one-time 6-month Medigap Open Enrollment Period — starts the first month you have Part B and you are 65 or older. If you enroll in Part B at, say, age 52 due to disability, that federal window has not opened yet. Outside it, insurers can generally use medical underwriting: they can decline your application or price it based on health history.
States can provide additional Medigap buying rights before 65, but the eligibility conditions and required plans differ:
- Some states allow anyone with Medicare under 65 to buy a Medigap policy.
- Some states only guarantee access if you have Medicare due to ESRD or disability.
- Many states offer no under-65 guarantee at all.
Ask your state insurance department which protections apply to your Medicare eligibility basis and Part B start date.
State Examples: What a Guarantee Actually Looks Like
State rules differ in three ways: who is guaranteed access, when the window opens, and what insurers may charge. These examples illustrate the range — always confirm current rules with your own state before applying.
Florida
Under Florida law, every insurer selling Medicare Supplement policies in the state must offer its policies to people under 65. Once you are enrolled in both Part A and B — regardless of age — you have 6 months of guaranteed-issue access, plus a 2-month window after employer group coverage ends. Florida also requires issue-age pricing, so your premium does not rise solely because you get older, but it can increase for other reasons. Also, under-65 rates for disability and ESRD beneficiaries are higher than age-65 rates, and you can re-apply at 65 for the lower rate.
If you spend part of the year in Florida, note the distinction that matters here: residence, not travel, determines which state’s rules and rates apply. Medigap is portable for care anywhere in the U.S. that accepts Medicare, but the policy you buy — and the protections that come with it — are governed by your state of residence. That is why comparing Medigap plans in Florida only answers the question for someone who actually lives there.
Pennsylvania
Pennsylvania’s open enrollment rule prohibits insurers from denying or pricing a Medigap policy based on health status during the 6-month period beginning when an individual enrolls in Part B, and requires each currently offered policy to be made available “without regard to age“. Because the protection attaches to Part B enrollment rather than age 65, under-65 beneficiaries who enroll in Part B fall inside it. Pre-existing condition exclusions are reduced or waived with at least 6 months of prior creditable coverage. This is a good illustration of why, when evaluating Pennsylvania Medigap rates and insurers, the state’s open-enrollment structure matters as much as any individual premium.
Virginia
Virginia requires every insurer issuing Medigap policies in the Commonwealth to offer at least one policy to residents under 65 who are eligible for Medicare due to disability and enrolled in Parts A and B, with a 6-month application window starting the month of disability-based Medicare eligibility (or notification of a retroactive SSA eligibility decision), and a 63-day window after group coverage ends. Effective January 1, 2024, insurers also may not charge under-65 disability enrollees more than the 65-year-old rate for the same plan. When reviewing Virginia Medigap rates and switching options, remember these protections are Virginia-specific and do not transfer if you move to another state.
New York
New York goes further than almost any state: state law requires any insurer writing Medigap to accept a Medicare enrollee’s application at any time of year, with no denial or premium discrimination based on health status — and those protections apply whether you are eligible by age, disability, or ESRD.
Comparison Framework: What to Check in Your State
| Question to answer | Why it matters |
|---|---|
| Does my state guarantee under-65 Medigap access at all? | Determines whether you can apply now or must wait until 65 |
| Which plans must insurers offer under-65 applicants? | Guarantees often cover a limited set (for example, at least Plan A), not every lettered plan |
| When does my window open and close? | Windows are typically 6 months from Part B enrollment or 63 days after losing other coverage |
| May insurers charge under-65 applicants more? | Some states allow separate (higher) under-65 rate classes; some cap them |
| Do I have a pre-existing condition waiting period? | Up to 6 months is possible, usually reduced by prior creditable coverage |
If your state offers no guarantee, your realistic alternatives are usually a Medicare Advantage plan (available in most areas to people with Medicare due to disability), Medicaid if your income qualifies, or keeping employer/union coverage as long as it lasts. Note that insurers generally cannot sell you Medigap if you have Medicaid or a Medicare Advantage plan.
If You Have Both Medicare and Medicaid
Eligibility changes the analysis entirely. If you qualify for both programs, Medigap is generally off the table — insurers usually cannot sell you a policy — but Medicaid itself covers many cost-sharing gaps. In that situation, the more relevant comparison is among Medicare Advantage options for dual-eligible beneficiaries, which exist specifically for people with both Medicare and Medicaid and depend on the plans available in your county. Eligibility and plan availability are local, so verify both before drawing conclusions.
Where This Fits in Your Broader Medicare Decision
This article is one piece of a larger question. Age of enrollment, prior coverage, employer situations, and health history all interact with the rules above, so it helps to understand your Medigap eligibility options as a whole before submitting any application. A wrong-timed application can mean a denial on record or a medically underwritten premium you did not need to accept.
If Cost, Not Access, Is Your Problem
Some readers under 65 should not buy Medigap at all because programs exist to cover their gaps directly. If your income and resources are limited, look into Medicare Savings Programs, which help pay Part A and/or Part B premiums and, at some levels, deductibles and coinsurance, plus the federal Extra Help program for Part D drug costs. These are public assistance programs with their own eligibility rules and application routes through your state Medicaid office or the Social Security Administration — they are not private-plan benefits, and qualifying for them changes which private coverage makes sense. If that sounds like your situation, start with this overview of help paying Medicare premiums and prescription costs before comparing Medigap premiums.
How to Compare Quotes the Right Way
Policies with the same standardized letter have the same basic benefits, so compare premiums, pricing methods and discount terms for equivalent coverage. Insurer service and the ability to afford future premiums also matter:
- Pick your plan letter first. For people new to Medicare on or after January 1, 2020, Plans C and F are not available; Plan G is the most comprehensive widely sold option, with Plan N as a lower-premium, shared-cost alternative.
- Identify every insurer licensed in your state that sells that letter. Medicare.gov’s plan finder and your State Insurance Department list them.
- Request actual under-65 rates in writing. Do not rely on 65-year-old sample rates; several states permit higher under-65 rate classes.
- Ask the pricing method — community-rated, issue-age-rated, or attained-age-rated — because it determines whether your premium climbs as you age.
- Ask about underwriting if you are outside a guaranteed window, and about pre-existing condition waiting periods and creditable-coverage credit if you are inside one.
- Use your free SHIP counselor (shiphelp.org) for unbiased, state-specific help.
No published table can substitute for step 3: rates are set by zip code, age class, and pricing method, so the only meaningful comparison uses quotes generated for your actual situation.
Bottom Line
Under 65, the answer to “can you buy Medigap?” is written in state law, not federal law. Confirm your state’s guarantee (or lack of one), confirm the timing of your enrollment window, and only then compare same-letter premiums from licensed insurers in your state. Before you commit to any plan or carrier, gather same-letter quotes for your exact age and zip code and have them reviewed side by side — that side-by-side comparison is the single most valuable next step, and it is the one an independent agent can help you prepare.
