You’ve just turned 65, there’s a stack of Medicare mail on your kitchen table, and one envelope promises to protect you from “unlimited out-of-pocket costs.” You open it. The monthly premium makes your coffee go cold. Is that price reasonable? Too high? Is there something cheaper that does the same job?
I hear these questions every single week. The honest answer: Medigap pricing is genuinely complicated, but it’s absolutely learnable. Here’s what actually drives those costs, what you can expect to pay, and how to make sure you’re not leaving money on the table.
What Is Medigap and Why Does It Cost Anything?
Medigap, also called Medicare Supplement Insurance, is private health insurance designed to fill the “gaps” in Original Medicare (Parts A and B). Original Medicare is powerful. It’s not complete.
You get stuck with a Part A hospital deductible (which resets every benefit period, not every year), a Part B deductible, and a 20% coinsurance charge on most outpatient services. There’s no annual cap on what you owe. A long hospital stay or serious diagnosis can expose you to tens of thousands of dollars in cost-sharing.
Medigap policies are sold by private insurance companies to cover some or all of those costs. The federal government standardizes what each plan must cover, which is genuinely helpful. A Plan G from Blue Cross Blue Shield and a Plan G from Mutual of Omaha must cover the same benefits by law. What they don’t have to match is the premium they charge you for it.
So why does Medigap cost money on top of your Part B premium? Because you’re buying a real insurance product, underwritten by a private company, and that company needs to price it so it can pay claims. Think of it like homeowner’s insurance layered on top of a base warranty. The government sets the rules; the market sets the price.
The Real Range: What People Actually Pay for Medigap
| Medigap Plan | Monthly Premium Range (65yo) | Coverage Level | Key Limitation |
|---|---|---|---|
| Plan G | $80-$300+ | Most comprehensive | Doesn’t cover Part B deductible ($240/year in 2024) |
| Plan N | $80-$300+ | Moderate | $20 office visit copays, $50 ER copay, no Part B excess coverage |
| High-Deductible Plan G | Under $50-$300+ | Comprehensive after deductible | $2,800 annual deductible (2024) |
| Plan K | Lower | Limited | Only partial cost-sharing coverage |
| Plan L | Lower | Limited | Only partial cost-sharing coverage |

There is no single “typical” Medigap premium. The range is genuinely wide.
Monthly premiums for Plan G and Plan N, the most popular options, generally fall somewhere between $80 and $300 or more per month for a 65-year-old woman in good health. Men often pay slightly more because insurers can factor in gender in most states. A 75-year-old shopping for the same coverage can see premiums that are significantly higher, sometimes double what a 65-year-old pays, depending on how the insurance company prices its policies.
Plan G is currently the most comprehensive plan available to new Medicare enrollees. Plan F, which was slightly richer, closed to new enrollees in 2020. Plan G covers everything except the Part B deductible, which in 2024 is $240 per year. Plan N is a step down. It has lower premiums, but you’ll pay up to $20 copays for office visits and up to $50 for emergency room visits, and it doesn’t cover Part B excess charges.
High-deductible Plan G is a third option worth knowing about. It carries a deductible of $2,800 in 2024, meaning you pay that amount in costs before the plan kicks in. In exchange, monthly premiums can be dramatically lower, sometimes under $50 per month for a healthy 65-year-old in a favorable zip code. If you’re relatively healthy and rarely use medical care, this version can save you significant money over time.
The lowest-cost options, Plan K and Plan L, cover only a portion of your cost-sharing and have annual out-of-pocket limits. They’re less common, but they might suit someone who wants catastrophic protection without comprehensive first-dollar coverage.
The Four Factors That Move Your Premium Up or Down
Understanding what drives the price helps you shop smarter.
1. Where you live. This is the biggest one. Insurance is regulated state by state, and premiums can vary dramatically between zip codes, even within the same state. Someone in rural Kansas might pay half what someone in urban Florida pays for identical Plan G coverage. Some states, including Massachusetts, Minnesota, and Wisconsin, have their own standardized plan structures that differ from the federal framework, which changes the pricing picture entirely.
2. How the insurance company prices its plans. This is called the “rating method,” and it’s one of the most important concepts in Medigap shopping. There are three types:
- Community-rated: Everyone in the plan pays the same premium regardless of age. A 65-year-old and an 80-year-old pay the same. Premiums can still rise over time due to inflation and claims experience, but age isn’t a factor.
- Issue-age-rated: Your premium is locked in based on the age you were when you enrolled, and it never goes up because you get older. It can still rise due to inflation.
- Attained-age-rated: Your premium increases as you get older. This is the most common method and it’s why many people see their Medigap bills creep up year after year, sometimes significantly.
If a company is offering you a very low price today, ask which rating method they use. A rock-bottom attained-age-rated premium at 65 can become painful at 75.
3. Your age and gender at the time of enrollment. Older applicants pay more with attained-age and issue-age plans. Gender is a factor in most states, with men typically paying somewhat higher premiums.
4. Whether you use tobacco. Most insurers charge smokers a surcharge, sometimes 10% to 20% more.
One thing that does NOT typically affect your Medigap price: your health history, at least during your Open Enrollment Period. During the six months that starts the month you’re both 65 and enrolled in Part B, insurers must sell you any plan they offer at the standard rate, no matter your health conditions. Miss that window, and in most states, companies can medically underwrite you and either charge more or deny coverage altogether.
How to Shop and Compare Medigap Prices Step by Step
Shopping for Medigap doesn’t have to feel overwhelming.
Step 1: Nail down your enrollment period. Know whether you’re in your Open Enrollment Period, another guaranteed-issue period, or applying outside any protected window. This determines whether you’ll face medical underwriting.
Step 2: Decide which plan letter fits your situation. For most people, the choice comes down to Plan G, High-Deductible Plan G, or Plan N. If you see a lot of specialists and want zero out-of-pocket surprises, Plan G is the cleanest option. If you want lower premiums and can handle modest copays, Plan N makes sense. If you’re healthy and comfortable with a deductible acting as a self-insurance buffer, High-Deductible Plan G deserves a serious look.
Step 3: Use Medicare.gov’s Medigap comparison tool. Go to Medicare.gov and use their plan finder. You can see which companies sell a given plan in your zip code, though this tool doesn’t always show live premium quotes.
Step 4: Get quotes from multiple companies. Because benefits within a plan letter are identical, you’re purely shopping on price, financial strength, and customer service. Get quotes from at least four or five insurers. Independent brokers who specialize in Medicare can pull these quotes quickly across many carriers. AARP’s Medicare resource center at aarp.org also has tools and guidance.
Step 5: Check the rating method. Ask each company directly: “Is this plan community-rated, issue-age-rated, or attained-age-rated?” Get the answer in writing if you can.
Step 6: Look up financial ratings. Use AM Best or similar rating agencies to check the insurer’s financial strength. You want a company that will be around and solvent for decades.
Step 7: Talk to a free SHIP counselor. The State Health Insurance Assistance Program, SHIP, offers free one-on-one counseling from trained volunteers in every state. They have no financial incentive to sell you anything. Find your local program at shiphelp.org. I always recommend this step, especially for anyone who feels unsure.
Medigap vs. Medicare Advantage: A Quick Cost Comparison
A lot of people ask whether Medigap is worth the premium when Medicare Advantage (Part C) plans often advertise $0 monthly premiums. It’s a fair question.
| Factor | Medigap + Part D | Medicare Advantage |
|---|---|---|
| Monthly premium | $80 to $300+ | Often $0 to $50 |
| Deductibles / copays | Mostly covered by Medigap | Varies; can be significant |
| Network restrictions | None (any provider that takes Medicare) | Usually limited network |
| Out-of-pocket maximum | Usually very low or none | Legally capped but can be high |
| Prescription drugs | Requires separate Part D plan | Usually included |
| Best for | Frequent healthcare users, travelers, people who want predictability | Healthy people who prefer lower upfront costs and don’t mind networks |
Neither is automatically better. But if you develop a serious illness and your costs spike, Medigap’s predictability has real value. If you’re healthy and rarely go to the doctor, the lower upfront cost of Advantage can work in your favor. Just know that switching from Medicare Advantage back to Medigap later in life can be very difficult if you have health conditions, because you’ll likely face underwriting outside your Open Enrollment Period.
The real takeaway: Medigap pricing rewards people who shop actively, enroll at the right time, and understand how rating methods affect long-term costs. Don’t take the first quote you see, and don’t let anyone pressure you into a decision. Take your time, get several quotes, call a SHIP counselor if you want an unbiased second opinion, and choose a plan that fits how you actually live and use healthcare, not just the one with the lowest number on the flyer. You’ve earned this coverage, and getting it right matters.
