Medicare Supplement premiums can increase even when your benefits stay exactly the same. Rates may rise because of your policy's pricing method, your age, rising healthcare costs, claims experience within the insurer's policy block, or an insurance-company rate adjustment filed or approved under your state's rules. The reason for your increase matters — an age-related change and a carrier-wide rate increase are not necessarily the same thing.

What You'll Learn Here
Frequency
Yes. There's no rule that limits a Medigap policy to a certain number of increases, or that guarantees a rate stays flat for any period of time. In practice, most Medicare Supplement policyholders can expect their premium to change in most years — either from aging (if the policy is attained-age-rated), from a carrier-wide block adjustment, or both at once. A year without any change is possible, but it isn't something you should plan around.
The Core Confusion
Almost every question about a Medigap rate increase comes back to this distinction. It helps to know which one — or both — applies to your notice.
Tied to your birthday, not the company's finances
If your policy is attained-age rated, your premium can rise simply because you got a year older — separate from any company-wide rate action. This type of increase is predictable and usually disclosed when you first bought the policy.
Applied to an entire class of policyholders
The insurer can also raise rates for an entire policy block because of claims experience, healthcare utilization, medical inflation and other actuarial factors — regardless of your individual age or health. This type of increase is harder to predict and can vary sharply by state and company.
You can see an age-related increase, a carrier rate increase, or both on the same notice. Which pricing method your policy uses determines whether age plays a role at all — which brings us to the next question.
How Your Policy Is Priced
Insurance companies price Medicare Supplement policies using one of three methods. The method your policy uses determines whether your age is part of the increase at all.
Your premium is based partly on your age today, so it's built to increase as you get older — on top of any separate carrier rate change.
Your original premium is based on your age when you bought the policy. It won't rise simply because you have another birthday — but the insurer can still raise rates for the whole block for other reasons.
Everyone with the same policy in the community generally pays the same base premium regardless of age. The premium can still rise for other reasons, but age itself isn't one of them.

Common Misconception
The Part That Feels Unfair
Because coverage and price are two separate things by design. Medigap plan letters are standardized by the federal government, so a Plan G's benefits can't quietly shrink — what a Plan G covers this year is what it covered last year. Your premium, on the other hand, is set by the insurance company and can change based on your age, the block's claims experience, or rising healthcare costs generally, none of which touch the benefits themselves.
That separation is actually useful information: it means a rate increase is not a signal that something is wrong with your coverage. It's a pricing decision, and pricing decisions can be shopped.
Regulation
Medicare Supplement insurance is regulated at the state level, and state insurance departments generally review a carrier's rate filings before an increase can take effect. But there is no single nationwide cap on how much a Medigap rate can increase, and the review process, required justification, and any practical limits vary meaningfully from one state to the next.
In practice, this means the same carrier can file for very different increases in different states in the same year — which is exactly why we track filings state by state rather than quoting one national number. If you want to know what's actually been approved for your carrier and state recently, your state insurance department's rate-filing records are the most direct source, or we can walk through it with you.
Looking Ahead
Rate history provides context. It does not predict a carrier's future increases. A company's past filings can suggest a pattern — steady and moderate, or aggressive and volatile — but future increases still depend on that year's claims experience, medical cost trends, and what state regulators approve. Treat rate history as one input, not a guarantee.
When you do compare rate history — your own policy's or a company you're considering — make sure you're comparing the same things:
Two "20% increase" headlines can mean very different things in dollars depending on the starting premium — which is one more reason a single national statistic rarely tells the whole story.

Next Steps
Check whether it references your age, a policy-block or class-wide adjustment, or both. This tells you what you're actually dealing with.
A rate increase is not a cancellation. Your coverage continues as long as you keep paying the new premium — there's no reason to drop it while you look into your options.
Because Medigap benefits are standardized, another company may offer the same coverage at a different premium. It isn't guaranteed, but it's worth checking.
Outside your Open Enrollment Period or a guaranteed-issue situation, a new company may ask medical underwriting questions. Knowing this upfront avoids surprises.
If you do decide to switch, keep your current policy until the new one is confirmed, to avoid any gap in coverage.
