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. Medicare SELECT is described as a Medigap policy that usually has lower premiums 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 nine 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's where insurers can offer the most meaningful premium discount.

A few important rules apply:

• Plan C and the high-deductible Plan F are no longer available for purchase by people who become newly eligible for Medicare on or after January 1, 2020, as a result of the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA). That rule applies to SELECT versions of C and F as well.
• High-Deductible Plan G is sometimes sold as a SELECT policy, stacking two cost-savings features (a network plus a $2,950 annual deductible in 2026).
• 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.

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 how insurers 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 some tight-network markets, the discount can climb higher, but that is the exception rather than the rule.

The savings are real but rarely dramatic. If a standard Plan G runs $170 a month, a SELECT Plan G might come in around $140 to $155. That is roughly $180 to $360 a year. 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 and the annual Part B deductible at $283, 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's 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 doesn't 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 benefits when you use an out-of-network provider for non-emergency services. You're 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'd been treated in network. This is similar to how emergencies work under Medicare Advantage networks.

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 they 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 aren't enough network hospitals to make the model work.
• A handful of states (notably Massachusetts and Minnesota) use non-standardized Medigap rules that limit or reshape how SELECT is sold.

The fastest way to see what's 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-by-state Medigap rules also matter here, and our Medicare Supplement plans by state guide walks through how those local rules interact.

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 choosing between Medicare Advantage and Medigap but uncomfortable with Advantage's prior authorization and broader limitations. If you're weighing that choice, our Medigap vs. Medicare Advantage comparison walks through both sides.

Who should avoid SELECT plans

• Frequent travelers, snowbirds, and adult children of seniors who split time between states.
• People with established specialists outside the SELECT network.
• Anyone with complex or evolving health needs who values maximum provider choice.
• Rural residents where network 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's frequently missed by enrollees. Federal law gives SELECT enrollees a 12-month window to switch to a standard Medigap policy without losing guaranteed-issue protection. In some states, you may be able to buy another type of Medigap policy called Medicare SELECT. 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.

Path 1: The 12-month federal switch 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. This is spelled out in Medicare.gov's Medigap basics and repeated in the 2026 Medicare & You handbook.

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 for a Medigap policy 60 days before the date your coverage ends and no more than 63 days after your coverage ends.

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 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'd been treated in network. The network restriction only applies to non-emergency care, so you don't have to worry about being stuck with huge bills after a genuine ER visit.

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. You can also buy Plan A, B, C, D, F, or G in your state during specific guaranteed-issue windows, such as when you move out of the SELECT service area (60 days before to 63 days after coverage ends). Outside those situations, you may need to pass medical underwriting.

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're 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's actually available.
