The Medicare Supplement Companies We'd Compare First in 2026

Every Standardized Medigap Plan Is Identical — So What Actually Separates These Companies?

Every standardized Medicare Supplement plan — whether it's Plan N, Plan G, or Plan A — provides the exact same medical benefits, regardless of which company sells it.

Medigap plans are standardized by federal law — a Plan N, G, or A from a small regional carrier covers the same things as the same plan from the largest national insurer.

The same is true of High-Deductible Plan G.

So if the coverage never changes, what are you actually comparing?

After quoting thousands of Medigap plans, we've found it comes down to four things: current price, underwriting, discounts and extra benefits, and — for a couple of carriers — a genuinely unique plan design.

Below, we walk through each company individually, including current sample pricing, before pulling those four factors together.

The Medicare Supplement Companies Still Worth Comparing in 2026

There are dozens of Medicare Supplement carriers across the country, but not all of them make this guide. We focused on companies that:

• Have an established history in the Medicare Supplement market — generally five years or longer
• Have demonstrated long-term financial stability
• Are companies we regularly compare for our clients
• Continue to offer value through competitive pricing, underwriting, discounts, or unique plan features

With some carriers exiting the Medicare Supplement market in recent years, we've deliberately prioritized companies with a demonstrated long-term commitment to it.

Some companies on this list are among the cheapest today. Others aren't.

But every company below has earned a place because we believe they're established, trustworthy insurers still worth considering depending on your situation.

These are estimated sample premiums based on market trends; exact rates vary by age, ZIP code, gender, tobacco use, and household discounts, so treat these as a starting comparison, not a quote.

Companies Leading the Market Right Now

These are the companies doing something that genuinely separates them right now — whether that's price, underwriting, or plan design.

Established Companies That Continue to Earn Our Consideration

They're still reliable, trustworthy companies — they're just not as competitive right now.

Each of these has an established history and financial strength, even if pricing isn't their strongest selling point today.

The gap between the lowest and highest quote above can run $50–100 a month — hundreds to over a thousand dollars a year — for what is, letter for letter, identical coverage on whichever plan you choose.

That gap, not brand name, is what a real comparison should be based on.

And as market conditions shift, companies move between these two groups — this guide gets reorganized as that happens, not rewritten from scratch.

Which Company Leads in Which State?

Pulling every sample premium above into one place, here's who comes out ahead state by state — and it's worth noting the leader isn't always the same company across Plan N, Plan G, and Plan A, even within the same state.

High-Deductible Plan G and Physicians Mutual's Innovative Plan G aren't included in this comparison since they use different pricing structures — see the sections above for those.

*We don't have a HealthSpring sample premium for California in this data set, so treat UnitedHealthcare's Plan G lead there cautiously — get a direct HealthSpring quote for California before assuming the statewide pattern doesn't hold.

Notice Illinois, Pennsylvania, and California: UnitedHealthcare leads on Plan A even where HealthSpring or Mutual of Omaha wins Plan N and Plan G in those same states.

Don't assume the company that wins one plan wins them all.

If you're comparing Florida Blue specifically, its ZIP-code-based premiums for Plan N, Plan G, and Plan A all follow a similar pattern to each other, running roughly $180 to $332 depending on location and plan.

Even its cheapest sample ZIP doesn't beat HealthSpring's statewide Florida figures above.

Just How Big Is the Price Gap?

Here's the same data with real numbers attached — the lowest and highest premium we found for each plan in each state, and how much more the priciest company charges compared to the cheapest, for identical coverage.

▸

State — Plan	Lowest	Highest	% More Expensive
Pennsylvania — Plan N	HealthSpring $100.65	UnitedHealthcare $172.00	71% more
Pennsylvania — Plan G	HealthSpring $151.86	Mutual of Omaha $221.79	46% more
Pennsylvania — Plan A	UnitedHealthcare $119.54	Aetna $189.42	58% more
California — Plan N	Mutual of Omaha $151.57	Humana $231.29	53% more
California — Plan G	UnitedHealthcare $199.12**	Aetna $307.13	54% more
California — Plan A	UnitedHealthcare $150.16	Humana $268.10	79% more
New Jersey — Plan N	HealthSpring $122.56	UnitedHealthcare $186.80	52% more
New Jersey — Plan G	HealthSpring $181.47	Humana $244.81	35% more
New Jersey — Plan A	Mutual of Omaha $148.91	UnitedHealthcare $218.48	47% more

*Texas Plan A is the one figure on this whole page we'd flag as unusual — UnitedHealthcare's $409.75 doesn't match the pattern of any other state in its own table (all $119–$218) and is worth confirming with a current quote rather than treating as reliable.

**No HealthSpring sample premium exists for California in this data set, so this comparison is between the other carriers only.

Leave the Texas Plan A outlier aside, and the typical gap between the cheapest and priciest company for the same plan in the same state runs about 30% to 55% — averaging roughly 48%, with Pennsylvania Plan N (71%) and California Plan A (79%) as the widest legitimate spreads in this data.

That means picking the wrong company, even among established, reputable carriers, can cost close to half again as much for coverage that's letter-for-letter identical — which is why we run the numbers for each client's specific state and plan rather than defaulting to the same recommendation, or assuming your neighbor's company still applies to you.

Underwriting: Not Every Company Approves the Same Way

This is one of the biggest reasons people call an agent instead of shopping alone. A few things worth knowing:

• During your Medigap Open Enrollment period, you generally can't be denied or charged more for pre-existing conditions
• Outside that window, most companies require medical underwriting, and approval isn't guaranteed
• Certain situations trigger guaranteed issue rights regardless of timing — for example, losing other coverage involuntarily
• Underwriting flexibility varies by carrier and by state, and it can change year to year, so it's worth confirming current requirements rather than relying on general reputation alone

Companies that stand out for underwriting — not because one is universally "easier," but because each does something different:

• Mutual of Omaha: fast, largely electronic underwriting, including instant decisions for many people brand new to Medicare Part B, plus electronic policy and ID card delivery. That speed and simplicity is a big part of why it's usually one of the first quotes we run for HDG shoppers.
• Physicians Mutual: its Second-Chance Guarantee lets many new policyholders switch to another eligible Physicians Mutual Medigap plan within the first two years without answering health questions — a different kind of underwriting flexibility than a fast initial approval.

Underwriting approaches at other carriers on this page vary by state and can change year to year — worth confirming current rules with us directly rather than assuming last year's process still applies.

Discounts & Extra Benefits

You saw these called out under each company above — here's the same information side by side for a fast scan.

Notice the pattern: almost none of these are free, bundled perks.

They're either paid add-ons or discount programs, which is exactly why we weigh them below price and underwriting rather than above them.

Companies That Actually Do Something Different

This is where the article gets genuinely different from a standard company comparison — a small number of carriers offer something beyond the usual Plan G, Plan N, or HDG lineup.

Physicians Mutual — Innovative Plan G

Unlike most Medicare Supplement companies that compete primarily on price, Physicians Mutual offers a patented Innovative Plan G design that combines features of High-Deductible Plan G and standard Plan G.

Who should consider it: someone comparing standard Plan G versus High-Deductible Plan G, healthy beneficiaries planning to keep a Medigap policy long-term, people who want lower premiums initially without staying permanently in an HDG design, and beneficiaries who value additional preventive-care options where available.

Physicians Mutual is one of the few companies we don't compare solely on price. We compare it because it offers something genuinely different.

If a client is deciding between standard Plan G and High-Deductible Plan G, Innovative Plan G deserves to be part of that conversation.

It isn't automatically the right answer, but it's one of the few Medicare Supplement products that changes the discussion from simply "who's cheapest" to "which long-term plan design fits me best."

Mutual of Omaha — High-Deductible Plan G

Best for: someone who wants to see every option on the table — not just standard Plan G — before deciding.

Common Mistakes to Avoid

• Choosing a plan letter and a company at the same time, instead of deciding on the plan first and then comparing companies for that plan
• Assuming coverage differs by company for a standardized plan — it doesn't; Plan N, Plan G, and Plan A benefits are all federally standardized
• Applying outside your Open Enrollment window without checking underwriting first
• Picking a company based on brand recognition rather than current price and rate history
• Assuming you can switch Medigap companies anytime without answering health questions — outside Open Enrollment, most switches require underwriting

Why This Guide Changes Every Year

Five years ago, this guide would have looked completely different.

Aetna would have been near the top because of its pricing. Mutual of Omaha was far more competitive for standard Plan G. Physicians Mutual didn't have Innovative Plan G. HealthSpring wasn't winning as many quote comparisons as it is today.

That's exactly why we don't believe in permanent "best company" rankings. The Medicare Supplement market changes every year, and the companies that offer the best value change with it.

Every year we compare thousands of Medicare Supplement quotes. Some companies rise because they become more competitive on price. Others fall because premiums increase or competitors offer better value.

This guide reflects what we're seeing in today's market — not what was true five years ago, and not necessarily what will be true five years from now.

Bottom Line

If there's one lesson we've learned after 15+ years helping Medicare beneficiaries, it's this: since Plan G, Plan N, and HDG benefits are standardized, the company you pick doesn't change your coverage — it changes your price, underwriting, discounts, and occasionally your plan design options.

Every company on this page has an established history and financial stability. Some — HealthSpring, Mutual of Omaha, and Physicians Mutual — are also winning today on price, underwriting, or plan design. Others — UnitedHealthcare, Florida Blue, Humana, and Aetna — remain reliable and trustworthy, just not as competitive right now. Both groups are worth knowing.

Don't ask "which company is the best." Ask "which company is most competitive right now for my ZIP code and plan." That's the same question we ask for every client — and taking a few extra minutes to compare carriers offering identical benefits can easily save hundreds or thousands of dollars over the life of your policy.
