Best Medicare Supplement Companies in New Jersey

After helping Medicare beneficiaries compare Medigap plans for more than 15 years — including many clients in New Jersey — here's what I tell almost everyone who calls me about this.

The company matters less than most people think.

For most people, the decision that has the biggest impact on both premiums and out-of-pocket costs is choosing between Plan G, Plan N, and High-Deductible Plan G.

Once you've picked the plan letter, the company comparison is a much smaller decision than people expect.

The standardized Medicare benefits are the same regardless of which company sells the Plan G policy.

Why New Jersey Is Different

The Biggest Mistake We See

Plan G, Plan N, or High-Deductible Plan G?

This is the decision I'd spend the most time on before you ever look at a company name.

Plan G and Plan N cover almost identical Medicare-approved expenses.

The difference is premium and a small amount of outpatient cost-sharing.

Most of the first-time Medicare beneficiaries I work with end up choosing Plan G, and the reason is simple: they want to open a bill, pay it, and move on with their day.

If you see specialists often, don't want to track copays, or just want the simplest possible experience, Plan G is usually the easiest recommendation I can make.

Plan N tends to fit a different kind of client — someone who's generally healthy, doesn't mind an occasional office-visit copay, and would rather see that difference show up as real monthly savings.

When the gap between Plan G and Plan N is $40 or more, Plan N becomes hard to argue against.

High-Deductible Plan G is the one I'm more careful about recommending.

It tends to work best for someone who rarely goes to the doctor and has enough set aside to comfortably cover the $2,950 deductible if a heavier medical year happens.

It's mainly a fit for someone trying to lower a fixed monthly cost, not someone who can't absorb a bad year.

I'd steer someone away from it if covering that deductible would actually cause financial strain — the whole point of Medigap is protection from big, unpredictable bills.

The clients who end up regretting their choice are almost always the ones who picked based on premium alone, without thinking through how they actually use healthcare.

Someone who chose Plan N to save $15 a month sometimes ends up regretting it.

They feel anxious every time they schedule an appointment because they hadn't budgeted for the copay, and usually switch back to Plan G at their next opportunity.

This lines up with what New Jersey's own enrollment data shows.

Based on 2024 NAIC filings, 205,739 New Jersey Medigap policyholders (40.5%) are enrolled in Plan G, versus 92,348 (18.2%) in Plan N.

Another 143,117 (28.2%) are still on legacy Plan F, which is closed to anyone who became Medicare-eligible on or after January 1, 2020.

That's part of why we lead with Plan G here — it's already the plan most New Jersey beneficiaries land on.

Both plans still leave you responsible for the annual Part B deductible, which is $283 in 2026.

High-Deductible Plan G's deductible is $2,950 in 2026.

In many ZIP codes we've quoted recently, High-Deductible Plan G deserves a fresh look because the premium savings have become large enough that it's no longer automatically a niche option.

2026 New Jersey Medicare Supplement Rates

Your actual rate depends on ZIP code, gender, tobacco status, discounts, underwriting, and effective date.

See our Medigap cost by state breakdown for a wider comparison.

A brand note before you compare prices: Cigna sold its Medicare Supplement business to HCSC in 2025, so "Cigna" no longer appears on New Jersey's age-65 rate chart.

That business now shows up as HealthSpring National Health Insurance Co.

If you see either name while shopping, they're part of the same transition.

Plan G, age-65 male, June 2026.

The spread between the cheapest and most expensive company here is about $45 a month — wider than it's been in past years.

That's worth noticing before you assume brand-name pricing has stayed close together.

Over a year, that's roughly $535 in premium for the exact same standardized Plan G benefits — exactly the kind of gap comparing companies is meant to catch.

Plan N, age-65 male, June 2026.

HealthSpring National was cheapest on both plan letters this time.

But notice that Aflac and Horizon swap places between Plan G and Plan N — Aflac is more expensive on Plan G but cheaper than Horizon on Plan N.

That's exactly why we still say: compare the same plan letter across carriers, and don't assume any single company's ranking carries over from one plan to the other.

How I'd Shop If I Were New to Medicare

First, I'd decide how much risk I'm comfortable taking on — that's really what the Plan G vs. Plan N vs. HDG decision comes down to.

Then I'd compare all three side by side using my own numbers, not just a rule of thumb.

Once I knew which plan actually fit my budget and comfort level, I'd request quotes from several companies offering that exact plan, and only compare apples to apples.

Finally, if two companies landed within $10 to $15 of each other, that's when I'd stop looking at premium alone.

I'd start comparing household discounts, financial strength ratings, complaint history, and how often each company has raised rates recently.

Here's that same process as a quick checklist:

• Decide whether I want Plan G, Plan N, or High-Deductible Plan G.
• Get quotes from at least four companies.
• Compare the same plan letter only — never Plan G against Plan N pricing.
• Ask about household discounts.
• Pick the lowest-priced, financially strong carrier.
• If two companies are within about $10–15 a month of each other, compare household discounts, financial strength, complaint history, and recent rate increases before making a final decision.

Category Winners in New Jersey

Now that you know how to compare, here's how these four carriers actually stack up.

There isn't one objectively "best" company here — there's a best company for what you're prioritizing.

Because saving even $10 to $15 a month adds up over the course of a policy, we spend more time comparing premiums and discounts than brand names.

Why these four companies? We didn't choose Aflac, HealthSpring National, UnitedHealthcare, and Horizon because they're the biggest names available.

Two of them are, in a very literal sense: 2024 NAIC filings show UnitedHealthcare holds about 47.1% of New Jersey's Medigap premium and Horizon holds about 14.7%.

Together, that's roughly six out of ten Medigap dollars in the state.

The other two consistently show up among the more competitive rates on New Jersey's own SHIP chart.

If a fifth company is quoting you a meaningfully better rate, that's absolutely worth a look too.

Can You Switch Later?

During your six-month Medigap Open Enrollment Period — which starts once you're 65 or older and enrolled in Part B — your health history generally can't be used to deny you coverage.

It also can't be used to raise your premium.

Outside that window, insurers can typically require medical underwriting, with some guaranteed issue exceptions.

You can apply to switch at any time, but don't cancel an existing policy until the new one is actually approved.

New Jersey's SHIP program spells out these enrollment rules directly if you want to see them straight from the source.

If you don't buy during that first six-month window and try to enroll later, you're not locked out.

But the insurer can generally ask health questions and decide whether to accept you, and at what price.

That's exactly why I tell people not to wait for "the perfect plan" during their own enrollment period.

It's far easier to enroll while you have guaranteed acceptance and fine-tune later than to try switching in after the fact.

New Jersey also has protections that most state guides skip: an under-50 program offering Plan D to younger disabled Medicare beneficiaries, and a 12-month Part B window for disabled applicants ages 50–65.

If you're on Medicare due to disability, you also get a fresh six-month open enrollment window once you turn 65 and have Part B.

Turning 65 isn't just an age milestone here — it's another guaranteed-acceptance opportunity.

Bottom Line

If you remember only one thing from this guide, remember this: choose your plan before you choose your insurance company.

Once you've decided on Plan G, Plan N, or High-Deductible Plan G, comparing companies becomes much simpler.

The core Medicare benefits are standardized no matter who sells the policy.

Everything else — the company, the logo on the ID card, and the extra member perks — is secondary to making that first decision correctly.

With two carriers controlling roughly six out of every ten Medigap premium dollars in New Jersey, the plan-letter decision matters more here.

It matters more than which of a handful of large companies you end up with.
