Medicare SELECT Plans Explained: A Lower-Cost Medigap Alternative With a Network

What Is a Medicare SELECT Plan?

A Medicare SELECT plan is a type of Medicare Supplement (Medigap) policy that requires you to use a defined network of hospitals, and sometimes specific doctors, in exchange for a lower monthly premium. CMS defines Medicare SELECT as a Medigap policy that generally costs less than other Medigap policies but requires you to use specific hospitals or providers (a network), except in emergencies. Other than that network requirement, a SELECT policy must meet all the same rules as a regular Medigap plan. The benefits attached to each plan letter are standardized by federal law, so a SELECT Plan G covers the same standardized Medigap benefits as a non-SELECT Plan G.

The trade is straightforward: you give up some provider flexibility for non-emergency care, and the insurer charges you less. Original Medicare still pays its share no matter which provider you use. Only the supplemental (Medigap) portion is conditioned on staying in network.

SELECT vs. Standard Medigap: The Key Differences

Standard Medigap plans let you see any provider in the United States who accepts Medicare. There are no networks, no referrals, and no service-area restrictions. A SELECT plan keeps the same lettered benefits but layers two extra rules on top:

1. Network use for hospitals (and sometimes doctors) for non-emergency care.
2. Possible referral requirements from a primary care physician to see specialists.

Which Plan Letters Are Sold as SELECT?

Insurers can technically offer any standardized Medigap letter (A, B, C, D, F, G, K, L, M, N) as a SELECT policy. In practice, the most common SELECT offerings are Plan F SELECT, Plan G SELECT, and Plan N SELECT. Plan A is occasionally available as SELECT, but the richer plans (F, G, N) dominate the SELECT market because that is where insurers can offer the most meaningful premium discount.

A few important rules apply:

• Plan C and standard Plan F are no longer available for purchase by people who became newly eligible for Medicare on or after January 1, 2020, as a result of MACRA (Medicare Access and CHIP Reauthorization Act of 2015). That rule applies to SELECT versions of C and F as well. If you were Medicare-eligible before that date, you can read more in our Medicare Plan F guide.
• High-Deductible Plan G is sometimes sold as a SELECT policy, stacking two cost-savings features (a network plus the CMS-set annual deductible, which is $2,950 for 2026, up from $2,870 in 2025). Our High Deductible Plan G guide walks through when this stacked-savings approach makes sense.
• Massachusetts, Minnesota, and Wisconsin use their own non-standardized Medigap frameworks, so SELECT options in those states look different from the federal A-N chart. Our Medicare Supplement plans by state guide walks through how those waiver states handle SELECT.

How Much Cheaper Are Medicare SELECT Plans?

Medicare and most insurers describe SELECT premiums as "generally lower" than the same lettered standard Medigap, without quoting a fixed percentage. Based on 2026 state rate filings and how carriers market these plans, typical savings fall in the 5% to 20% range versus the equivalent non-network Medigap policy in the same ZIP code, though the exact number depends on carrier, age, gender, and tobacco status. In tight-network metro markets the discount can climb toward the top of that range, but for many buyers the savings land closer to 10% to 15%.

For context, the national average Plan G premium at age 65 in 2026 sits around $166 to $220 per month depending on the dataset, and the overall Medigap national average across plan letters is roughly $149.50 per month. A SELECT Plan G in the same market might come in about $20 to $50 lower each month, which adds up to $240 to $600 in annual savings. Your quote will differ by carrier, state, and rating factors, but that gives you a realistic ballpark for how SELECT premiums land this year.

The savings are real but rarely dramatic. If a standard Plan G runs $180 a month, a SELECT Plan G might come in around $145 to $170. Whether it is worth the network limits depends entirely on where you get care. With the 2026 standard Part B premium at $202.90 per month (up 9.7% from $185 in 2025) and the annual Part B deductible at $283 (up from $257), every dollar of Medigap premium savings adds up quickly against a bigger overall Medicare budget.

Network Rules and What Happens Out of Network

The network rule is the heart of how SELECT plans work. Here is the practical breakdown.

In-network non-emergency care

Medicare pays its usual share of approved charges. Your SELECT policy then pays the standardized Medigap benefits exactly as a non-SELECT version of the same letter would. You pay only what the plan letter does not cover (for example, the $283 Part B deductible under Plan G in 2026).

Out-of-network non-emergency care

Medicare still pays its portion of approved charges. However, the SELECT policy is generally not required to pay any supplemental benefits when you use an out-of-network provider for non-emergency services. You are personally responsible for the deductibles and coinsurance the plan would have covered in network.

Emergency care (anywhere)

Emergency care is the major exception. SELECT plans must let you use any hospital in a true emergency and still pay full supplemental benefits, just as if you had been treated in network. This is similar to how emergencies work under Medicare Advantage networks, but the underlying coverage still runs through Original Medicare rather than a private replacement plan.

State Availability of Medicare SELECT

Medicare SELECT is not available everywhere. CMS does not publish a national list, and availability is set by each insurer based on whether it can build a viable hospital network in a given service area. As a general rule:

• SELECT plans are most common in mid-sized to large metro areas where insurers can contract with a few hospital systems.
• They are rarely offered in rural states or low-population counties because there are not enough network hospitals to make the model work.
• A handful of states (notably Massachusetts, Minnesota, and Wisconsin) use non-standardized Medigap rules that reshape how SELECT is sold.

The fastest way to see what is available where you live is to enter your ZIP code on the Medicare Plan Finder and filter for Medigap policies. SELECT versions will be labeled. State insurance departments in Minnesota, Wisconsin, and several other states also publish annual SELECT rate charts you can cross-check. If you are comparing broader Medicare pathways at the same time, our Medigap vs. Medicare Advantage comparison lines up the two side by side.

Pros, Cons, and Who SELECT Plans Are Best For

Who SELECT plans work well for

• Seniors who already use one of the network hospital systems and have no plans to switch.
• People who stay close to home and rarely travel out of state.
• Budget-focused enrollees who want Medigap-style cost predictability at a lower premium.
• Anyone weighing Medicare Advantage against Medigap but uncomfortable with Advantage's prior authorization and narrower provider access. Our gaps in Original Medicare guide shows what Medigap fills that MA does not.

Who should avoid SELECT plans

• Frequent travelers, snowbirds, and adult children of seniors who split time between states. If you travel abroad, review our Medigap foreign travel emergency coverage guide before enrolling.
• People with established specialists outside the SELECT network.
• Anyone with complex or evolving health needs who values maximum provider choice.
• Rural residents where network hospital availability is thin.

Your Right to Switch From SELECT to Standard Medigap

This is one of the most important consumer protections built into Medicare SELECT, and it is frequently missed by enrollees. Federal law gives new SELECT enrollees a 12-month trial right to switch to a standard Medigap policy without medical underwriting. If you buy a Medicare SELECT policy, you have the right to change your mind within 12 months and switch to a standard Medigap policy on a guaranteed-issue basis.

There is also a helpful Medicare.gov rule to know: if you have held your Medicare SELECT policy for more than six months, you generally will not have to answer medical questions when applying for a new Medigap policy in certain situations. That six-month tenure removes some of the underwriting risk that comes with switching later.

Path 1: The 12-month federal trial right

Within 12 months of your Medicare SELECT policy start date, you can move to a standard Medigap policy on a guaranteed-issue basis, without answering health questions. Under federal rules, the guaranteed-issue letters typically available in this scenario include Plans A, B, K, and L (plus Plan C or F if you were first eligible for Medicare before January 1, 2020). Some states extend guaranteed-issue rights to additional letters like G or N, so check your state's rules.

Path 2: Switch back to a prior Medigap plan you held

If you had a regular Medigap policy first, then switched to SELECT, you have the right to switch back to that original Medigap policy if the same insurer still sells it. If not, you can buy Plan A, B, C, D, F, or G from any insurer in your state (subject to the MACRA rules that limit C and F to people eligible before 2020).

Path 3: Move out of the SELECT service area

If you move outside the SELECT plan's service area, you have a guaranteed-issue right to buy most Medigap plans sold in your new state, with no medical underwriting. You must apply no earlier than 60 days before the date your SELECT coverage ends and no later than 63 days after it ends to preserve that protection.

The extra 12-month protection

Medicare notes that your rights may last an extra 12 months in certain circumstances, and it advises contacting your State Insurance Department for details. These extended protections vary by state, so a SHIP counselor is often the fastest way to find out what applies to you.

Federal Medicare Advantage trial rights are a separate 12-month protection that lets you drop a Medigap policy to try Medicare Advantage and come back.

Frequently Asked Questions

Is a Medicare SELECT plan the same as Medicare Advantage?

No. Medicare SELECT is a type of Medigap (Medicare Supplement) policy that works alongside Original Medicare, just with a network requirement. Medicare Advantage (Part C) is a completely different program that replaces Original Medicare with private plan coverage. SELECT plans keep you on Original Medicare and pay secondary to it.

Can I get Plan G as a Medicare SELECT plan in 2026?

Yes, Plan G SELECT is one of the most commonly offered SELECT versions where availability exists. It provides the same standardized Plan G benefits (everything except the $283 Part B deductible in 2026) as long as you use network hospitals for non-emergency care. Premiums typically run 5% to 20% below standard Plan G in the same area, though the exact discount depends on your ZIP code, age, and carrier.

What happens if I have an emergency outside the SELECT network?

Emergency care is fully covered, even at out-of-network hospitals. Both Original Medicare and your SELECT policy pay their normal shares just as if you had been treated in network. The network restriction only applies to non-emergency care, so a genuine ER visit will not leave you stuck with huge unreimbursed bills.

How do I switch from a Medicare SELECT plan to a standard Medigap plan?

You have several options. Within 12 months of your SELECT policy start date, you can switch to a standard Medigap policy on a guaranteed-issue basis under federal rules (typically Plans A, B, K, and L, plus C or F if you were eligible before 2020). If you have had the SELECT policy more than six months, Medicare rules say you generally will not have to answer medical questions in certain switching scenarios. You can also use other guaranteed-issue windows, such as when you move out of the SELECT service area (apply from 60 days before to 63 days after coverage ends).

Are Medicare SELECT plans available in every state?

No. Insurers choose whether to offer SELECT plans based on whether they can contract with hospital networks in a given area. They are most common in metro areas and less available in rural states. Massachusetts, Minnesota, and Wisconsin use their own non-standardized Medigap frameworks, which affects how SELECT is sold there. Check the Medicare Plan Finder for your ZIP code to see what is actually available.
