High Deductible Plan G

High Deductible Plan G covers the same benefits as standard Plan G, but only after you pay a separate annual deductible out of pocket each calendar year. In exchange, its monthly premium is typically lower than standard Plan G’s, though how much lower depends on the insurer. Until you reach the deductible, the plan pays nothing. For some people that trade-off makes sense and for others it doesn’t, so it’s worth running the numbers first. Ohio’s Medigap rule (Ohio Administrative Code 3901-8-08) allows this plan and lets insurers sell it to people who became eligible for Medicare before or after January 1, 2020, though not every insurer chooses to sell it.

How High Deductible Plan G Works

High Deductible Plan G is built on the same benefit package as standard Plan G — Part A coinsurance and up to 365 extra hospital days, Part B coinsurance, blood, Part A hospice and skilled nursing coinsurance, the Part A deductible, Part B excess charges, and foreign travel emergency care. The difference is timing: instead of Plan G paying its share from the very first dollar of Medicare-covered cost-sharing, you pay those costs out of pocket first, up to an annual deductible. That deductible amount is adjusted every year for inflation under the federal standards that Ohio’s rule follows, and Medicare’s “Choosing a Medigap Policy” guide publishes the current figure, so it’s worth confirming it with us rather than relying on an old number. Once you’ve paid that amount in a calendar year, High Deductible Plan G pays 100% of the covered costs for the rest of that year. Like standard Plan G, it does not pay the Part B deductible, but the Part B deductible you pay counts toward the high deductible. The Part B excess charges benefit matters less in Ohio than elsewhere, because state law (Ohio Revised Code 4769.02) bars Ohio-licensed health care practitioners from balance billing Medicare beneficiaries, though a provider outside Ohio may be able to charge excess amounts.

Foreign travel emergency care is the one exception to the “same as Plan G” rule. It has its own separate calendar-year deductible (the standardized benefit sets it at $250), which you pay in addition to the high deductible. After that, the plan pays 80% of billed charges for covered emergency care during the first 60 days of each trip, up to a $50,000 lifetime maximum.

What Actually Counts Toward the Deductible

This trips people up more than any other detail: the High Deductible Plan G deductible counts your out-of-pocket costs for services that Medicare Part A and Part B cover — your deductibles, copayments and coinsurance that Medicare doesn’t pay, such as Part B coinsurance, the Part A deductible and the Part B deductible. It does not count your monthly premiums (for the plan itself or for Part B), it doesn’t count costs for anything Medicare doesn’t cover in the first place, and it doesn’t count the separate foreign travel deductible. In other words, it’s not just “money you spend on healthcare in general” — it’s specifically the Medicare-covered cost-sharing that you pay before the plan starts paying.

The Actual Math: Standard G vs. High Deductible G

The way to think about this clearly: take the annual premium difference between standard Plan G and High Deductible Plan G from the same carrier. If that premium savings is larger than the extra amount you’d actually have to pay under High Deductible Plan G, it costs you less in total even in a year where you hit the deductible completely. (One wrinkle: because the Part B deductible counts toward the high deductible, and you’d pay the Part B deductible yourself under standard Plan G anyway, the extra amount High Deductible Plan G puts on you is somewhat less than the full deductible.) If the premium savings is smaller than that extra amount, the comparison depends on how much of the deductible you actually expect to use in a typical year. For someone in good health with mostly routine care, a low-cost year can leave the lower premium well ahead, but the result depends on the two actual premiums and on your actual year, and premiums for both plans can change over time, so it’s a comparison to redo each year rather than a promise about future years. That’s the exact calculation we run with actual current rates pulled from your specific carrier options, rather than relying on generic national averages that may not reflect real Ohio pricing.

Who High Deductible Plan G Fits Best

This plan tends to make the most sense for people who are in reasonably good health, have enough savings set aside to comfortably cover the annual deductible in a worse-than-expected year, and would rather keep significantly more money in their pocket every month than pay for coverage they may not fully use. It’s a poor fit for someone who’s already managing an ongoing condition that reliably generates high Part B costs every year, since they’d likely hit the deductible annually anyway and might have been better off with standard Plan G’s spread-out premium.

A Real Comparison We Ran

A recently retired client in good health, with no ongoing conditions, asked us to compare his options after seeing standard Plan G’s premium and feeling like it was more than he wanted to commit to monthly. We pulled High Deductible Plan G rates from the same carriers, and the annual premium savings alone exceeded the deductible amount by a comfortable margin — meaning even in his worst-case year, he’d come out ahead of standard Plan G, and in a typical low-usage year, he’d save considerably more. He enrolled in High Deductible Plan G and set aside the deductible amount in savings just in case, which is exactly the kind of planning that makes this plan work well rather than becoming a financial surprise.

The Deductible Resets Every Year

Like most Medicare-related deductibles, the High Deductible Plan G deductible resets on January 1st regardless of when you enrolled or when you last used care. If you have a planned procedure, it’s worth thinking about the calendar — a procedure in late December followed by follow-up care in January could mean working toward the deductible twice in a short window, once for each calendar year.

Switching Between Standard and High Deductible Plan G

If your health changes — say, a new diagnosis makes frequent care more likely — you can apply to switch to standard Plan G, but outside a guaranteed-issue window, that application would typically be subject to medical underwriting, the same as any new Medigap application. Ohio has no “birthday rule” that would give you a yearly window to switch without health questions. That’s worth thinking about before enrolling: High Deductible Plan G works best when you’re comfortable with some uncertainty about your future health, since switching later isn’t automatically guaranteed.

Guaranteed Issue Rights

During your 6-month Medigap Open Enrollment Period, which starts the month you’re 65 or older and enrolled in Part B, an Ohio insurer that sells High Deductible Plan G can’t turn you down or charge you more because of your health (Ohio Administrative Code 3901-8-08(N)). Certain other guaranteed-issue situations, such as losing employer coverage or a Medicare Advantage plan leaving your area, can also open a window, but each right covers specific plan letters. Ohio’s rule names Plan F (including High Deductible F) for many of those rights and treats High Deductible Plan G as its equivalent for people who became eligible for Medicare on or after January 1, 2020, so whether a particular right lets you buy High Deductible Plan G depends on your situation, and it’s worth confirming with us or with the Ohio Department of Insurance (OSHIIP, 1-800-686-1578) before relying on it. Applying during your open enrollment window is especially worth prioritizing here, since re-qualifying for a Medigap plan later in life, after health changes, isn’t something you can count on.

Common Questions About High Deductible Plan G

Is this the same as a Medicare Advantage plan with a deductible?

No — High Deductible Plan G is still a Medigap plan that works alongside Original Medicare. You can generally see any provider that accepts Medicare, with no referrals needed (unless you choose a Medicare SELECT version of a Medigap plan, which uses a network). Medicare Advantage plans replace Original Medicare and set their own cost-sharing (copayments, coinsurance and sometimes a deductible, with a yearly out-of-pocket limit) and typically involve provider networks. They’re two fundamentally different approaches, not variations of the same thing.

Can I use an HSA to pay the deductible?

You can’t add new money, but money already in an HSA can generally still be used. Once you’re enrolled in Medicare, you’re no longer eligible to contribute to a Health Savings Account (IRS Publication 969), and the rule can reach back to the months your Medicare coverage was backdated. Funds you contributed before enrolling can generally still be used for qualified medical expenses, which can include Medicare-covered out-of-pocket costs. If you have an existing HSA balance, ask us or your tax adviser how it applies to your situation so you don’t run into a tax problem.

Does High Deductible Plan G cost less than Plan N?

It depends on the carrier and your usage — sometimes High Deductible Plan G’s premium alone beats Plan N’s, and sometimes not. Since you might reasonably be considering all three (standard Plan G, Plan N, and High Deductible Plan G), we typically compare all three together rather than looking at any pair in isolation.

Building a Cushion, Not Just Buying a Plan

We tell every client considering High Deductible Plan G the same thing: this plan works best when it’s paired with an actual savings plan, not just a lower premium bill. Since the deductible is a real, known number that resets annually, the smart approach is treating it like a bill you’re pre-paying into savings rather than hoping you won’t need it. Clients who set aside the deductible amount (or build toward it over their first year or two on the plan) tend to feel far more at ease with High Deductible Plan G than those who simply pocket the premium savings and hope for the best. We’re glad to help you think through that budgeting piece, not just the insurance comparison. See what cancer, heart attack, and stroke actually cost for exactly why that cushion matters.

What Happens the Year You Hit the Deductible

If you do happen to have a genuinely high-cost year and meet the full deductible, High Deductible Plan G pays 100% of covered Part A and Part B cost-sharing for the remainder of that same calendar year — Part A and Part B coinsurance, the Part A deductible, excess charges and the rest of the Plan G benefit list. That’s an important reassurance: the plan isn’t “cheap coverage with a catch,” it’s Plan G coverage with a delayed start each year. Once you’ve paid in for the year, the Medicare-covered benefits match standard Plan G (except for the Part B deductible, which neither version pays, and the separate foreign travel deductible) until the calendar flips again.

Let’s Run the Numbers on All Three

Because so many of our clients in Bethel, Cincinnati, Hamilton County, Clermont County, Butler County, and Warren County end up genuinely weighing standard Plan G, Plan N, and High Deductible Plan G against each other, we’ll pull real quotes for all three from the carriers actually available in your specific area and walk through the trade-offs side by side — no real pressure at all, and no assumption that any one of the three is automatically the right choice for you before we’ve actually run your numbers. Bring a rough sense of your typical annual healthcare spending if you have it, since that single detail often does more to settle the comparison than any general rule of thumb ever could.
