What Is the Medicare Supplement (Medigap) Birthday Rule—and Why It May Hurt More Than Help?
The Medicare Supplement Birthday Rule, or Medigap Birthday Rule, is a state-level policy that allows Medicare beneficiaries to change their Medigap plan annually around their birthday without medical underwriting. While intended to help those with pre-existing conditions access new coverage, the rule often leads to unintended negative consequences, including increased premiums and reduced plan availability. These rules, now active in several states like California, Oregon, and Idaho, may seem consumer-friendly on the surface but are ultimately a regulatory misstep that disrupts pricing stability.
According to MedigapSeminars.org, the Birthday Rule backfires by forcing insurers to accept applicants without assessing health risk, which drives up costs for all enrollees. As premiums rise, some consumers are priced out of Medigap entirely and pushed into less suitable Medicare Advantage plans. Additionally, insurers are exiting states with birthday rules, and brokers are increasingly uncompensated—limiting consumer access to guidance. The article warns that well-meaning state legislation is inadvertently harming the very people it aims to protect and proposes a more targeted solution that better balances access with sustainability.
As the title of the video indicates, I will be discussing Medicare supplement Birthday rules in this video. But if you think that is what this video is really about, you would be wrong.
The real theme of this video is the unintended and disastrous consequences of state government Medicare override rules and how they harm the consumer they were intended to protect. Birthday rules are just one such beast that is doing more harm than good. The unintended consequences are a disappointing surprise, like finding a nice lump of coal wrapped, with a bow on top.
I have got some real entertaining examples for you of the mess created by Birthday Rules and other state government actions in this video. It doesn’t matter if your state has a birthday rule or is considering one or not, this video will show you why you need to tell your state legislature to stop trying to protect you from the evil corporations that provide your healthcare insurance.
But this isn’t just a rant. Not only will it show you what others have hidden, I will provide a potential solution to this rather significant problem. A simple solution that protects all consumers

Introduction to Medicare Supplement
Medicare Supplement, commonly known as Medigap, is a type of private insurance designed to bridge the gaps in original Medicare coverage. These gaps often include out-of-pocket costs such as deductibles, copays, and coinsurance, which can add up quickly and become a financial burden. Medigap plans come in various types, each offering a unique set of benefits and coverage levels to suit different healthcare needs and budgets.
Understanding the different Medigap plans is crucial for Medicare beneficiaries. For instance, some plans might cover additional services like foreign travel emergencies, while others might offer lower premiums but higher out-of-pocket costs. By familiarizing themselves with these options, beneficiaries can make informed decisions that best align with their healthcare needs and financial situation. In essence, Medigap plans provide a safety net, ensuring that unexpected medical expenses don’t derail one’s financial stability. Medigap Seminars is dedicated to educating clients about their Medicare options, ensuring informed decision-making.
Understanding Medicare Part B and Part A
Medicare is a comprehensive program divided into several parts, each covering different aspects of healthcare. Medicare Part A, often referred to as hospital insurance, covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health care. On the other hand, Medicare Part B, known as medical insurance, covers doctor visits, outpatient care, medical supplies, and preventive services.
Medicare Part C, or Medicare Advantage, offers an alternative to original Medicare. These plans are provided by private insurance companies and often include additional benefits such as dental, vision, and hearing coverage. Medicare Part D focuses on prescription drug coverage, helping beneficiaries manage the costs of their medications.
Understanding how these parts work together is essential for navigating the complex healthcare system. For example, while original Medicare (Parts A and B) provides broad coverage, it doesn’t cover everything. This is where Medigap plans come into play, filling in the gaps and providing more comprehensive coverage. By grasping the nuances of each part, beneficiaries can better manage their healthcare and ensure they have the coverage they need.
What is a Birthday Rule?

A Birthday Rule is a general term for a state law that overrides Medicare and creates a window of time annually where a person can switch Medigap plans or insurance companies without medical underwriting. The Birthday Rule allows beneficiaries to switch their supplemental insurance without going through the underwriting process. The insurance company must accept your application.
Some states call this an Anniversary Rule with the window of time to apply for a supplement around your current Medigap policy anniversary. Beneficiaries must stay with the same insurance carrier to take advantage of the Birthday Rule.
The Birthday Rule allows beneficiaries to switch to plans with fewer benefits without going through medical underwriting. This means that beneficiaries can change their Medigap plans without facing the typical restrictions associated with pre-existing conditions.
The state’s birthday rule allows beneficiaries to switch to a plan of equal coverage. This flexibility ensures that beneficiaries can adjust their coverage to better suit their needs.
The benefit of the Birthday Rule is that it allows beneficiaries to change their Medigap plan annually. This provides an opportunity to reassess and adjust coverage based on changing health or financial situations.
The Birthday Rule eliminates the waiting period for switching Medigap insurance. This means beneficiaries can change their plans without delay.
Beneficiaries with health conditions should consult their department of insurance for more information. This ensures they understand the specific regulations and options available to them.
The Birthday Rule is subject to specific rules and allows switching to plans with equal or lesser coverage. This ensures beneficiaries have the flexibility to adjust their plans without facing unnecessary barriers.
Beneficiaries can switch to a new insurance plan with equal or lesser coverage. This provides an opportunity to find a plan that better meets their needs.
Beneficiaries enrolled in a Medicare Advantage plan cannot switch back to Original Medicare. This restriction is important to understand when considering coverage options.
Switching to plans with the same or lesser benefits does not require health underwriting. This makes it easier for beneficiaries to adjust their coverage without facing medical assessments.
Medigap enrollees can switch to a new plan during the Birthday Rule window. This provides an annual opportunity to reassess and adjust their coverage.
Beneficiaries must stay with the same insurance carrier to switch from their current plan. This requirement is crucial for taking advantage of the Birthday Rule.
Each state has its own rules for switching from traditional Medicare to Medigap. Understanding these state-specific regulations and how HSAs interact with Medicare is essential for making informed decisions.
Medigap policyholders have a 30-day window during their birthday month to switch plans. This designated period provides flexibility for adjusting coverage.
Beneficiaries can switch to a supplemental insurance plan of equal or lesser value. This ensures they can find a plan that meets their needs without facing additional underwriting.
Why are there Birthday Rules?



On an annual basis, 15% to 20% of Medicare supplement policy applications are rejected due to pre-existing medical conditions. In most states, those people with serious critical or chronic illness cannot change their Medicare supplement because of their health.
The birthday rule gives them that opportunity.
Now, while a birthday rule sounds warm and fuzzy and would make such a nice feel good law to force evil insurance companies to help the disadvantaged, the truth is that Birthday Rules are double Edged sword that do more harm than good.
I will explain why and share some great examples in a moment. We are going to have some fun with this one.
An important problem is that state legislatures often think there are no unintended consequences for their feel-good laws. They usually think that because Medicare Advantage plans have no medical underwriting, Medicare supplement plans should too, so in the words of the great Jean Luke Picard, captain of the Enterprise, they “make it so” with a new law.
Medicare Advantage Plans are subsidized by you and I, the U.S. taxpayer. They are financially compensated monthly by The U.S. Government to accept everyone who applies.
Medicare supplement plans do not enjoy such taxpayer funded compensation.
The result, while the 15% or 20% of people who have health issues can make changes, everyone, all 100% of the people who have or want a Medicare supplement in that state will pay higher rates. Everyone is harmed.
Studies show that on an annual basis, Medicare supplement rate increases in states with Birthday rules are 15% to 20% higher than states without those rules. That is annually, and compounds out to be a significant difference over time.
In some cases, the prices in Birthday rule states are so high that the people the legislation was trying to help can no longer afford a supplement. They are priced out of the market and pushed into zero premium Medicare Advantage plans.
Why do Medigap Premiums Increase?
I showed in my last video on Massive Medicare supplement price increases <insert thumbnail in upper right> that the insurance companies will often solicit underwritten business in order to improve the average health of their Medicare supplement pool. People that can pass medical underwriting are healthier than those that cannot, so targeting that group helps to stabilize the policy premiums.
Well, when the state has a Birthday Rule, the insurance company is knee capped. They can’t solicit healthy people because everyone waits for their birthday rule window and the insurance company has no idea if they are healthy or a massive healthcare expense. As a result, the insurance company is forced to increase their rates and charge everyone as if they were unhealthy.
It typically takes two to three years or so after the implementation of a birthday rule to start to see the impact on prices. But let’s take a look at a few real life examples.
Let’s start with Idaho, who recently made two changes to their rules on Medicare supplement plans. Pay attention to this…it’s classic
That means that all Medicare supplement plans offered in Idaho were priced using the Issue Age model. In my opinion the most consumer-friendly pricing models.
Issue Age means that you will always pay the price for the age you were when you were first issued the policy. If you bought your policy at age 65, you always pay the age 65 rate. That rate can increase over time, but your premium will be whatever other people that age are paying.
There was No birthday rule.
At the start of the year 2022, a 65 year old man in Boise Idaho could purchase a Plan N at $117 / month, then pay the age 65 year old rate the rest of their life.
If you waited until age 85 to purchase a Plan N supplement, it would cost you $162 / month.
In February 0f 2022 state legislature introduced a Birthday rule and made all new Medigap Plans Community Rated so that when you switched plans your age was not factor in the price.
Today, just three years later, at age 65 a man can buy a Plan N and will need to pay between $162 and $180 / month…at age 65. $162 a month instead of $117.
In addition, one in four Medicare supplement insurance companies in Idaho stopped offering plans in that state. Now consumers have fewer choices.
Because their state government stepped in to “save them”, Idaho residents turning age 65 will pay more than some of their peers would ever have to pay, ever, before the government saved them from the evils of capitalism.
Way to-go Idaho legislature. You get the trophy for stupid mistakes. Don’t worry, seven other states are trying hard, as I speak, to take that trophy from you. I am sure one will win that trophy from you soon enough.
How the Birthday Rule Works
The Medigap Birthday Rule is a provision that allows Medicare beneficiaries to switch their Medigap plan to another plan with equal or lesser benefits without undergoing medical underwriting. This rule is available in certain states and provides an annual opportunity for beneficiaries to reassess and change their Medigap coverage based on their current healthcare needs and financial situation.
Typically, the birthday rule offers a 30-day window following the beneficiary’s birthday to make a switch. During this period, beneficiaries can enroll in a new Medigap plan without being turned away due to pre-existing conditions or medical history. This flexibility is particularly beneficial for those whose healthcare needs have changed over the year or who have found a more affordable plan that better suits their situation. By allowing these changes without the hurdle of medical underwriting, the birthday rule ensures that beneficiaries can maintain appropriate and cost-effective coverage.
Guaranteed Issue Right
A Guaranteed Issue Right, also known as Medigap protection, ensures that an insurance company cannot deny a beneficiary a Medigap policy or charge them higher premiums due to pre-existing conditions or medical history. Similarly, the Medicare Hold Harmless Provision ensures protection for Social Security Income (SSI) recipients from increased Medicare premiums. This right is typically available during the initial open enrollment period or in specific situations where the beneficiary’s health coverage changes, such as losing other health coverage or moving out of a Medicare Advantage plan’s service area.
With a Guaranteed Issue Right, beneficiaries can enroll in a Medigap plan without answering health questions or undergoing medical underwriting. This protection is crucial for those with pre-existing conditions, as it prevents insurance companies from denying coverage or imposing higher premiums based on health status. By guaranteeing access to Medigap policies, this right helps ensure that all beneficiaries can obtain the supplemental coverage they need to manage their healthcare costs effectively.
Birthday rules help the few at a cost to everyone.



Just a few years ago there were only nine states that had birthday rules. Today there are seventeen states and seven other states who have proposed laws in legislature.
I will scroll on one side of the video screen those states with current birthday or anniversary like rules, followed by those states with proposed legislation.

Benefits of the Medicare Birthday Rule
The Medicare Birthday Rule offers several significant benefits to Medicare beneficiaries. Firstly, it provides an annual opportunity to reassess and change Medigap coverage based on current healthcare needs and financial situation. This flexibility allows beneficiaries to switch to a plan with equal or lesser benefits without undergoing medical underwriting, which can be a significant advantage for those with pre-existing conditions.
Additionally, the birthday rule can help beneficiaries save money by allowing them to switch to a more affordable Medigap plan. For instance, if a beneficiary finds a plan that offers the same or better coverage at a lower premium, they can make the switch during the birthday rule window without the fear of being denied due to their medical history. Overall, the Medicare Birthday Rule is an important protection for Medicare beneficiaries, providing them with more flexibility and control over their healthcare coverage, ensuring they can adapt their plans to meet their evolving healthcare needs and financial circumstances.
Which States Have a Birthday rule?
As of May 2025, several U.S. states have implemented the Medicare Supplement “state’s Birthday Rule”, which grants Medigap policyholders an annual opportunity to switch plans without medical underwriting. This rule is designed to offer flexibility and potentially more affordable options for beneficiaries.
Which States Have Birthday Rules?



The following states have enacted the Medigap Birthday Rule:
California: The California Birthday Rule provides a 90-day window starting 30 days before and ending 60 days after the beneficiary’s birthday to switch to a Medigap plan with equal or lesser benefits, including changing insurance carriers .
Idaho: Allows a 63-day period post-birthday to change to a plan with equal or lesser benefits, with the option to switch carriers .
Illinois: Offers a 45-day window from the beneficiary’s birthday for those aged 65 to 75 to switch to a plan with equal or lesser benefits, limited to the same insurance company or its affiliates .
Kentucky: As of January 1, 2024, provides a 60-day window starting on the beneficiary’s birthday to switch to a plan with the same benefits, including changing insurance carriers .
Louisiana: The Louisiana Birthday rule grants a 63-day period from the beneficiary’s birthday to switch to a plan with equal or lesser value benefits, limited to the same insurance company or its affiliates .
Maryland: Effective July 1, 2023, allows a 30-day window from the beneficiary’s birthday to switch to a plan with equal or lesser value benefits, including changing insurance carriers .
Nevada: Provides a 60-day period starting on the first day of the beneficiary’s birth month to switch to a plan with equal or lesser benefits, including changing insurance carriers .
Oregon: Offers a 30-day window starting on the first day of the beneficiary’s birth month to switch to a plan with equal or lesser benefits, including changing insurance carriers .
Oklahoma: Allows beneficiaries to switch to another plan at any time outside of the open enrollment period, provided they have maintained coverage for at least 90 days. For those with Medigap Plans B through N, they can switch to any Plan B through N with no health questions asked.



States Considering Medigap Birthday Rules in 2025
Several states are evaluating the adoption of the Medigap Birthday Rule in 2025:
Wyoming: A proposal is under consideration to allow a 63-day window around the beneficiary’s birthday to switch to a plan with equal or lesser benefits without health underwriting .
Indiana: Legislation introduced in early 2025 proposes a 60-day window starting on the beneficiary’s birthday to switch to a plan with the same benefits, including changing insurance carriers .
Delaware: Currently reviewing legislation to implement a Medigap birthday rule, though specific details are pending.
Nebraska: Considering a 30-day window starting on the beneficiary’s birthday to switch to any Medigap plan, regardless of current coverage .
Iowa: Proposed legislation suggests a 30-day window starting on the beneficiary’s birthday to switch to a plan with equal or lesser benefits, including changing insurance carriers .
Rhode Island: Evaluating a 30-day window starting on the beneficiary’s birthday to switch to any Medigap plan, with provisions for those transitioning from Medicare Advantage .
New Mexico: Considering a 60-day window post-birthday for beneficiaries aged 65 and older to switch Medigap plans.
With each of these, the Medigap birthday rule is starting to significantly disrupt the insurance company’s ability to manage their premiums.
OK, as of right now here is what we know:
When a state initiates a birthday rule for Medicare supplement plans, everyone’s premium rates increase. It often takes a couple years, but once prices increase they continue at a rate higher than those states without the birthday rule.
Second, Medigap insurance companies exit the market. I mentioned Idaho earlier; I know also that Nevada had 34 Medicare supplement insurance companies doing business in the state prior to their birthday rule announcement in 2023. As of last week, there are only 25 insurance companies remaining. None have left, with more about to leave. The consumer is left with fewer choices.
Lastly, there is another problem that Medigap birthday rules create. A problem that hits closer to home for me and some of my audience will be very surprised by.
All but a few insurance companies do not compensate agents or brokers for an application made using the Medigap birthday rule. This means no guidance. No help. We try, but no company can afford to work for free for long.
There are a few states, nine I believe, that require insurance companies to compensate agents for guaranteed issue business, like birthday rule applications.
But all of this is about to take a turn for the worse, for consumers and agents alike.
As I was writing this video outline, several insurance companies warned me to be on the lookout for letters coming to agents in the next couple weeks. These letters will announce changes in their contracts stating that certain insurance companies will no longer compensate agents for any business in birthday rule states.
The message they are sending us is that they no longer want the business. For now, they don’t want Medicare supplement sales in these states. The Medigap Birthday Rule is making it too difficult to manage premiums.
I guess I will know exactly who and how many insurance companies soon, but I have already letters from two companies and expect more.
Personally, I believe that after a hiatus these SOME of these insurance companies will come back with plans priced much higher, perhaps similar to what we see in New York.
Why New York?
New York is among the most expensive states in the country for Medicare supplement plans because New York has perpetual open enrollment and a lot of corporate regulations.
A 65-year-old in New York will pay $350 to $600 a month for a Plan G Medigap insurance.
In addition, there are only six or seven insurance companies left offering Medicare supplement plans in New York. No one else wants to offer Medicare supplemental insurance products in that market.
So, in addition to higher prices, and fewer choices, state legislatures are putting the small independent Medicare insurance broker out of business. I feel sad for some of the agents trying to build a good business, often working alone and almost every day of the week….and now their state is threatening their livelihood.
Can someone remind me who is supposed to win with a birthday rule?

The Medigap Birthday rule solution
Here, in my opinion, is a solution.
Instead of having a Medigap birthday rule where everyone can shop for a Medigap policy annually without medical underwriting, make the rule more specific for those who need it.
The rule should simply be that if a person applies for a Medicare supplement plan via medical underwriting and is denied, then that person can have a Medigap birthday rule option on the next birthday. They can then apply for any plan offered by the same insurance company or any affiliate and cannot be turned down.
This is a Simple solution that serves those who the current birthday rules are trying to help, without overwhelming an insurance company with countless applications for annual Medicare supplement switches.
It’s a surgical approach to Medigap Birthday rule benefits that is more manageable and sustainable.
A Medicare supplement is not an Advantage plan and is not subsidized by the taxpayer. They do not have the money to take on everyone regardless of health. If the state government attempts to force this change without providing taxpayer funding to support it, the only place that funds can come from is via higher premiums. You and everyone in your state who has a Medicare supplement plan will pay the higher cost.
Even more, many insurance companies and individual agents who specialize in Medicare will simply walk away from offering a Medigap policy. They are driven out of business or out of state. For those interested in the exceptional service and positive reviews clients have shared, read more about Medigap Seminars.
In my opinion, the unintended consequences of implementing a birthday rule are much worse than the benefits of such state legislation. Medigap coverage becomes more costly, sometimes too costly as premium increases of more than 40% become commonplace.
