In short
- The deductible is $2,950 in 2026 and rises to $3,050 in 2027, per CMS. After you meet it, the plan pays like regular Plan G for the rest of the calendar year.
- Your Part A deductible, Part B deductible, Part B coinsurance and other Medicare-covered costs all count toward it. Premiums and prescriptions don't.
- Using an illustrative Lincoln example, High-Deductible Plan G comes out ahead unless your Medicare cost sharing in a year tops about $2,000.
- Your worst case is the deductible plus a year of premiums, so you need savings that can absorb a $3,050 bill in 2027.
- Moving from High-Deductible G to regular Plan G later usually means health questions in Nebraska, since there's no birthday rule.
High-Deductible Plan G is a bet on your own health, with a ceiling on how much you can lose. You pay a much smaller premium every month, and you agree to cover the first few thousand dollars of Medicare-covered costs yourself in a bad year. Here's exactly how big that ceiling is, and how to tell if the bet is a good one for you.
What is High-Deductible Plan G?
It's Plan G with a yearly deductible in front of it. Until your share of Medicare-covered costs reaches the deductible, you pay those costs yourself. Once you reach it, the plan pays exactly like regular Plan G for the rest of the calendar year: the Part A hospital deductible, hospital and skilled nursing coinsurance, the 20% Part B coinsurance and Part B excess charges.
| Year | High-deductible Plan G deductible |
|---|---|
| 2026 | $2,950 |
| 2027 | $3,050 |
CMS sets the deductible each year, and it resets every January 1. Like every supplement, it has no network and works with any provider in the country that accepts Medicare.
What counts toward the $3,050 deductible?
The deductible counts the Medicare-covered costs you'd owe with Original Medicare alone. That includes:
- The Part A hospital deductible ($1,736 per benefit period in 2026).
- The Part B deductible ($283 in 2026).
- The 20% coinsurance on doctors, outpatient surgery, imaging and therapy.
- Skilled nursing coinsurance for days 21 to 100 ($217 a day in 2026).
- Part B excess charges from doctors who don't accept assignment.
What doesn't count: your monthly premiums, your prescriptions (those go through a separate Part D plan with its own $700 deductible and $2,400 cap in 2027), and anything Medicare doesn't cover, like routine dental. Emergency care outside the U.S. carries a separate $250 yearly deductible.
Notice how fast a hospital stay eats the deductible. One admission's $1,736 Part A deductible is more than half of the 2027 deductible by itself. Add the surgeon's 20% and you're likely there.
What does High-Deductible Plan G cost in Nebraska?
On October 2, 2026, the Medicare.gov Medigap tool showed High-Deductible Plan G estimates for a 65-year-old in Nebraska from about $37 to $111 a month. The Nebraska Department of Insurance's 2026 fact sheet listed $38 to $75. For comparison, regular Plan G's starting estimates in Lincoln ran from $137 to $311, with the middle around $205. These are estimates, not quotes.
Medigap companies only have to offer Plan A, so not every company that sells regular Plan G sells the high-deductible version. Your list to compare may be shorter. Rating method still matters here. Most Nebraska Medigap policies are attained-age rated, so a high-deductible premium also rises as you age.
How does the math work against regular Plan G?
Here's an illustration using 2026 rules for a 65-year-old in Lincoln. I'm assuming $205 a month for regular Plan G, near the middle of the Lincoln range, and $60 a month for High-Deductible Plan G. Those are example premiums, not quotes. "Cost sharing" means the Medicare-covered costs Original Medicare would leave you that year.
| Sample year (2026 rules) | Regular Plan G: premiums plus what you pay | High-Deductible Plan G: premiums plus what you pay | Difference |
|---|---|---|---|
| Light year: $500 of cost sharing | $2,460 + $283 = $2,743 | $720 + $500 = $1,220 | High-deductible saves $1,523 |
| Middle year: $1,800 of cost sharing | $2,460 + $283 = $2,743 | $720 + $1,800 = $2,520 | High-deductible saves $223 |
| Bad year: $6,000 of cost sharing | $2,460 + $283 = $2,743 | $720 + $2,950 = $3,670 | Regular G saves $927 |
The break-even in this example is about $2,023 of cost sharing in a year. Below that, the high-deductible plan wins. Above it, regular Plan G wins, but never by more than $927 in this example, because the deductible caps your exposure. In 2027, the higher $3,050 deductible pushes that worst case up by $100.
Run it over several years and the picture gets clearer. Two light years and one bad year still leaves the high-deductible plan ahead in this example: $1,523 + $1,523 minus $927 is about $2,119 saved over three years. A string of bad years flips that. Your own quotes and health history decide which story is more likely.
How does paying the deductible work in real life?
Medicare still pays first, exactly as it would with any supplement. After a visit or a hospital stay, Medicare processes the claim and sends you a Medicare Summary Notice showing the approved amount and your share. Until you've reached the deductible, the provider bills you for that share, and you pay it the way you'd pay any medical bill.
Your Medigap company tracks how much of your share has counted toward the deductible. Once you cross it, the company starts paying your share, and the bills to you stop for the rest of that calendar year. Keep your Medicare Summary Notices and receipts in one folder, so you can check the running total yourself. Then on January 1, it starts over.
That's also why timing matters. A hospital stay in November and a follow-up surgery in February can mean meeting the deductible twice, once in each year.
Who should consider High-Deductible Plan G?
It tends to fit people who:
- Are healthy, take few medications and rarely see specialists.
- Have savings set aside that can cover the full deductible in any given year.
- Want any-doctor freedom, like regular Plan G, at a much lower premium.
- Are disciplined enough to treat the premium savings as their own deductible fund.
It's usually a poor fit if you have a chronic condition with regular specialist visits, an upcoming surgery, or no cushion for a $3,050 bill. Paying the deductible every year makes the lower premium pointless.
Can you use HSA money with High-Deductible Plan G?
You can't contribute to a health savings account once you're enrolled in Medicare, and Part A can be retroactive up to 6 months when you sign up late, so the timing matters. My page on HSAs and Medicare explains that lookback.
Money you've already saved in an HSA is a different story. Under IRS Publication 969, it can generally pay qualified medical expenses, which can include the costs you pay toward the high deductible. It can also pay Medicare premiums once you're 65, such as Part B and Part D. It can't pay Medigap premiums, so the High-Deductible Plan G premium itself has to come from other money. If you have a large HSA balance, this plan and that account can work well together. Talk to your tax adviser about your situation. I'm not an accountant.
What are the risks of High-Deductible Plan G?
- Getting to regular Plan G later isn't guaranteed. Nebraska has no birthday rule. After your Medigap open enrollment window, moving up to regular Plan G means health questions, and the company can say no.
- The deductible goes up. It rose from $2,950 to $3,050 for 2027, and it can rise again.
- Premiums still rise. A low premium can still go up with claims, inflation and age.
- A big year arrives all at once. Your out-of-pocket costs show up in the months right after a hospital stay, not spread across the year.
How does it compare with Plan N and Medicare Advantage?
Plan N gets you a lower premium through small, frequent copays and leaves the big costs covered. High-Deductible Plan G gets you a much lower premium by taking on the first few thousand dollars yourself. Medicare Advantage has a yearly out-of-pocket limit too, but adds networks, prior authorization and copays. See Plan G vs High-Deductible Plan G for the side-by-side and Medigap vs Medicare Advantage for the bigger choice.

Frequently asked questions
CMS set the 2027 deductible for high-deductible Plans F and G at $3,050, up from $2,950 in 2026. You pay Medicare-covered costs, like deductibles, coinsurance and copays, up to that amount in a calendar year. After that, the plan pays its full share for the rest of the year, the same as regular Plan G. The deductible starts over each January.
Yes. The high deductible counts the Medicare-covered costs you pay yourself, and the Part B deductible ($283 in 2026) is one of them. So are the Part A hospital deductible ($1,736 per benefit period in 2026), the 20% Part B coinsurance and skilled nursing coinsurance. Your monthly premiums and your prescription costs don't count toward it.
You can apply, but in Nebraska the company can usually ask health questions and decline you, unless you're in your 6-month Medigap Open Enrollment Period or have a guaranteed issue right. The state has no birthday rule. If you're likely to want regular Plan G within a few years, or your health could change, weigh that before you start with the high-deductible version.
No. Like every standard Medigap plan, it works with any doctor or hospital in the United States that accepts Medicare, with no referrals. That includes Lincoln's Bryan Health and CHI Health hospitals and Nebraska Medicine in Omaha, as long as the provider accepts Medicare. The exception would be a Medicare SELECT version, which uses a hospital network.
You can't put new money into an HSA once you have Medicare. Money already in your HSA can generally pay qualified medical expenses, like the costs you pay toward the deductible. IRS Publication 969 also allows Medicare premiums for people 65 and older, but specifically excludes premiums for a Medicare supplemental policy such as Medigap. Check with your tax adviser for your situation.
Anyone who can buy a Medigap policy in Nebraska, including people new to Medicare on or after January 1, 2020. High-deductible Plan F has the same deductible but can only be sold to people who were eligible for Medicare before 2020. Companies are only required to offer Plan A, so not every company that sells regular Plan G sells the high-deductible version.
