Medicare Plan G Pros and Cons: Is the Premium Worth It?

Medicare Supplement Plan G is the most enrolled Medigap plan in the United States. It covers nearly everything Original Medicare does not, which makes it appealing. But with premiums ranging from $130 to over $300 per month in 2026, and many carriers raising rates by 12% to 26% this year, the question is no longer just 'what does Plan G cover?' The real question is whether the premium is worth what you get in return.

This article gives you an honest breakdown of the pros and cons of Plan G, not a sales pitch. We will cover what it actually costs, what it does not cover, and who should consider alternatives like Plan N or High-Deductible Plan G instead.

What Plan G Actually Covers

Plan G is a federally standardized Medigap plan. This means every Plan G from every insurance company covers the exact same benefits. The only differences between carriers are price, customer service, and rate increase history.

Here is what Plan G pays for in 2026:

• Part A hospital deductible ($1,736 per benefit period)

• Part A coinsurance and hospital costs up to 365 additional days after Medicare benefits are exhausted

• Part B coinsurance (the 20% you normally owe on outpatient services)

• Part B excess charges (amounts above Medicare's approved rate)

• Skilled nursing facility coinsurance ($217.50/day for days 21-100)

• First three pints of blood

• 80% of foreign travel emergency care (up to plan limits)

The only Medicare cost-sharing Plan G does not cover is the annual Part B deductible, which is $283 in 2026. Once you pay that $283, Plan G covers 100% of your remaining Medicare-approved costs for the year.

The Pros of Medicare Plan G

1. Near-complete cost predictability

With Plan G, your maximum annual out-of-pocket cost for Medicare-covered services is $283 (the Part B deductible) plus your monthly premium. That is it. No surprise hospital bills. No 20% coinsurance on a $50,000 surgery. No skilled nursing facility charges. For people on fixed incomes who need to budget precisely, this predictability is the single biggest advantage.

2. No network restrictions

Unlike Medicare Advantage, Plan G has no provider network. Any doctor, specialist, or hospital in the country that accepts Medicare accepts your Plan G. You never need referrals. You never need prior authorization. If you travel, see specialists in other states, or simply want the freedom to choose any provider, this is a significant advantage over network-based plans.

3. Part B excess charge protection

Doctors who accept Medicare but do not accept 'assignment' can charge up to 15% above Medicare's approved amount. Plan G covers these excess charges in full. Plan N does not. While excess charges are relatively uncommon (only about 1% of Medicare claims involve them), they can add up if you see specialists who do not accept assignment.

4. Guaranteed renewable

Once you have Plan G, your insurer cannot cancel your policy or change your benefits regardless of your health. As long as you pay your premium, you keep your coverage. This is particularly valuable as you age and develop health conditions that might make you uninsurable under a new policy.

5. Portable across all 50 states

If you move, your Plan G moves with you. Coverage works identically in every state because it supplements Original Medicare, which is a federal program. Your premium may change based on your new location, but your benefits remain the same.

6. Simpler claims process

In most cases, your doctor bills Medicare, Medicare pays its share, and then automatically forwards the remaining claim to your Medigap insurer. You rarely have to file paperwork or fight claim denials the way Medicare Advantage enrollees sometimes do.

The Cons of Medicare Plan G

1. The premium is not cheap

This is the biggest con. Plan G premiums in 2026 typically range from $130 to $300+ per month depending on your age, location, gender, and carrier. That is $1,560 to $3,600+ per year before you use a single medical service. For comparison, many Medicare Advantage plans have $0 monthly premiums (though they shift costs to when you actually use care).

2. Premiums increase every year

Plan G premiums are not locked in. They rise annually due to medical inflation, your aging, and the overall claims experience of your carrier's risk pool. In 2026, many carriers raised Plan G rates by 12% to 26%, with some filing increases above 40%. Over a 20-year retirement, compounding rate increases can make Plan G significantly more expensive than it was when you first enrolled.

3. Does not cover the Part B deductible

Plan G leaves the $283 annual Part B deductible uncovered. This is a minor con in dollar terms, but it is worth noting because Plan F (no longer available to new beneficiaries after 2020) did cover it. If you are comparing Plan G to a grandfathered Plan F, this is the only coverage difference.

4. No dental, vision, or hearing coverage

Plan G covers Medicare cost-sharing only. It does not add any benefits that Original Medicare itself does not cover. That means no dental cleanings, no eyeglasses, no hearing aids, and no routine foot care. You need separate policies or out-of-pocket spending for these. Medicare Advantage plans often include these benefits at no additional premium.

5. No prescription drug coverage

Plan G does not cover medications. You must enroll in a separate Medicare Part D plan for prescription drug coverage, which adds another $10 to $100+ per month in premiums. This is another area where Medicare Advantage plans often bundle drug coverage into the plan.

6. Medical underwriting outside Open Enrollment

If you do not enroll in Plan G during your 6-month Medigap Open Enrollment Period (starting when you turn 65 and enroll in Part B), you may face medical underwriting. Insurers can deny you coverage or charge higher premiums based on pre-existing conditions. This makes timing critical and creates a 'lock-in' effect: once you leave Plan G, getting back in may be difficult or impossible if your health has changed.

7. You pay the premium whether you use care or not

If you are healthy and rarely visit the doctor, you are paying $1,560 to $3,600+ per year for coverage you may not use much. Unlike Medicare Advantage, where your costs are lower when you use less care, Plan G charges the same premium regardless of utilization. For healthy 65-year-olds, this can feel like overpaying for peace of mind.

Pros and Cons Summary Table

Is the Premium Worth It? A Real Cost Analysis

Whether Plan G's premium is 'worth it' depends on how much healthcare you actually use. Here is a straightforward comparison for a 67-year-old in 2026:

The math is clear: Plan G is expensive insurance against expensive outcomes. In healthy years, you are overpaying relative to what you would have spent without it. In major medical years, it saves you tens of thousands of dollars. The question is whether you can afford to self-insure the risk of a bad year.

Who Should Choose Plan G

Plan G is the right choice if you match most of these criteria:

• You want maximum cost predictability and are willing to pay a higher monthly premium for it

• You have chronic conditions or anticipate significant healthcare usage

• You travel frequently or see providers in multiple states

• You want freedom to see any specialist without referrals or prior authorization

• You are within your Medigap Open Enrollment Period and can lock in coverage without underwriting

• You can comfortably afford $150-$250/month in premiums on top of your Part B premium ($202.90/month in 2026)

Who Should Consider Alternatives

Plan G may not be the best fit if:

• You are healthy, rarely visit the doctor, and are comfortable taking on more financial risk in exchange for lower premiums

• Your budget is tight and $150-$300/month in Medigap premiums (on top of Part B) strains your finances

• You want dental, vision, hearing, and drug coverage bundled into one plan (consider Medicare Advantage)

• You primarily see local providers and do not need nationwide network freedom

• You are outside your Open Enrollment Period and would face high underwriting premiums

💡 Eddie's Pro Tip

Do not compare Plan G's premium to zero. Compare it to what you would actually spend without it. Pull up last year's Medicare Summary Notices and add up your cost-sharing. Under $2,000? Plan N might save you money. Over $3,000? Plan G is already paying for itself.
