Medicare Supplement Birthday Rule: Can You Change Your Medigap Plan Without Medical Underwriting?

Did you know your birthday could be an opportunity to save money on your Medicare Supplement insurance?
If you already have a Medicare Supplement plan, also known as Medigap, you may be paying more than you need to. In certain states, a law commonly called the Medicare Supplement Birthday Rule lets eligible policyholders switch insurance companies around their birthday without medical underwriting.
For Indiana residents, this opportunity became available on January 1, 2026. Kentucky residents have had similar protections since January 1, 2024. But what exactly does the Birthday Rule mean? Who qualifies? And can you keep the same Medicare Supplement benefits while potentially lowering your monthly premium?
Let's break it down.
What is the Medicare Supplement Birthday Rule?
The Medicare Supplement Birthday Rule is a state-level insurance protection that lets eligible individuals with a Medigap policy change coverage during a special enrollment window tied to their birthday.
Under qualifying circumstances, an insurance company cannot deny your application because of your medical history or existing health conditions. This is especially important for folks who may have developed health conditions since they purchased their original Medicare Supplement policy.
Without a guaranteed-issue right, changing Medigap insurance companies after your initial enrollment period may require you to answer medical questions and qualify through underwriting.
The Birthday Rule creates another opportunity to compare insurance companies without those medical underwriting barriers.
Indiana's Medicare Supplement Birthday Rule: What Changed in 2026?
Indiana's new Medigap Birthday Rule, established through House Enrolled Act 1226, became effective January 1, 2026. As we move into 2027, too few people know about this opportunity. This law gives eligible Indiana Medicare Supplement Policyholders age 65 and older an annual opportunity to change insurance companies without medical underwriting.
Who Qualifies for Indiana's Birthday Rule?
To use Indiana's Birthday Rule, you generally must:
Be at least 65 years old
Already have an active Medicare Supplement insurance policy
Apply to a different insurance company
Apply within the state's 60-day birthday-related enrollment window
Select the same lettered Medicare Supplement plan you currently have, including the applicable plan variation
For example, if you currently have Medicare Supplement Plan G with one insurance company, you may qualify to switch to Plan G with another company. Indiana's Birthday Rule does not guarantee a right to switch from Plan G to Plan N.
When Can an Indiana Resident Use the Birthday Rule?
Indiana's State Health Insurance Assistance Program (9SHIP) explains that the annual opportunity begins about one month before your birthday and continues about one month afterward.
Because the law specifies a 60-day application period, verify your exact eligibility dates before applying.
Can You Be Denied Because of Your Health?
If you qualify under Indiana's Birthday Rule, the new insurer cannot deny or medically underwrite your application based on your health status, medical conditions, or previous claims. For someone managing diabetes, heart disease, cancer, or another medical condition, this protection can make comparing Medicare Supplement companies much more accessible.
Remember: Guaranteed acceptance does not mean every insurance company charges the same premium. Rates can still vary based on permitted rating factors.
Does Kentucky Have a Medicare Supplement Birthday Rule?
Yes! Kentucky also has a Medicare Supplement Birthday Rule. Kentucky's law took effect January 1, 2024, giving eligible policyholders an annual opportunity to switch Medicare Supplement insurance companies without medical underwriting.
Kentucky's rule generally allows an eligible individual to apply for the same lettered Medigap plan with a different insurance company during a 60-day period beginning on their birthday.
For example, a Kentucky resident currently enrolled in Medicare Supplement Plan N may be able to compare Plan N premiums from other insurance companies during this period. Although Indiana and Kentucky have similar protections, their enrollment windows differ. This is one reason it can help to work with an insurance professional familiar with your state's requirements.
Is the Medicare Supplement Birthday Rule Available in Every State?
No. No nationwide federal Medicare Supplement Birthday Rule exists.
Instead, states decide whether to offer additional guaranteed-issue protections beyond federal Medicare requirements. As of November 2026, states with birthday-related Medigap switching protections include California, Delaware, Idaho, Illinois, Kentucky, Louisiana, Maryland, Nevada, Oklahoma, Oregon, Utah, Virginia, West Virginia, and Wyoming.
Other states may offer different protections. For example, Missouri has a switching rule tied to the anniversary of a Medicare Supplement policy, not the policyholder's birthday. The specific requirements, enrollment windows, insurance company restrictions, and plan options vary by state.
The takeaway: Before assuming you must remain with your current Medicare Supplement company, check whether your state offers a guaranteed-issue switching opportunity.
Why Would You Want to Change Medicare Supplement Insurance Companies?
One of the biggest reasons is cost. In most states, Medicare Supplement plans are standardized by letter. This means the core benefits of a standard G plan, for example, are the same regardless of which insurance company offers the policy.
However, the monthly premiums can vary between companies. You could potentially be paying more for the same standardized coverage.
Example: Comparing Medicare Supplement Plan G Premiums
This is hypothetical
Insurance Company | Monthly Premium |
Company A, current Plan G | $225 |
Company B, new Plan G | $180 |
Potential Savings | $45 |
Potential Annual Savings | $540 |
Illustration only, not an actual insurance quote or guaranteed savings.
Both policies would provide the same standardized Plan G benefits, assuming they are the same plan variation. The difference is the premium.
Over time, even a modest monthly reduction can lead to meaningful savings.
Can You Change Medicare Supplement Plans If You Have Preexisting Conditions?
Under a qualifying Birthday Rule, yes. This is one of these laws' most valuable aspects. For example, suppose you purchased a Medicare Supplement Plan G when you first became eligible for Medicare. Since then, you have developed a chronic medical condition.
Under ordinary circumstances, applying for a different Medicare Supplement policy outside a protected enrollment period would most likely involve medical underwriting. But if you qualify for your state's Birthday Rule, you may be able to switch insurance companies without having your application denied because of that condition. This does not mean you can automatically move to any Medicare Supplement plan. State-specific restrictions still apply.
Is the Medicare Supplement Birthday Rule the Same as Medicare Open Enrollment?
No, and this distinction matters. Medicare has several different enrollment periods.
What Should You Compare Before Switching Medicare Supplement Companies?
A lower premium matters, but it shouldn't be your only consideration. Before changing companies, you need to consider:
Your current premium: How much are you paying each month?
Available insurance companies: Are other companies offering your same Medicare Supplement plan at a lower price?
Future premium increases: How has the company historically adjusted rates? Past increases do not fully guarantee future results.
Policy details: Are you comparing the same standardized plan and applicable variation?
Your enrollment deadline: Are you applying within the guaranteed-issue window?
Coverage effective dates: Will the new policy begin without an unintended gap in coverage?
Do not cancel your current Medicare Supplement policy until your new coverage has been approved and its effective date is confirmed.
Your Birthday Could Be a Good Time for a Medicare Supplement Review
Many people review their Medicare coverage when they first turn 65, but their insurance needs and monthly premiums can change over time. That monthly premium surely increases year after year. If you already have a Medicare Supplement policy, your birthday may just be a valuable reminder to review what you're paying and determine whether another insurance company could offer a better rate for the same standardized benefits.
You do not necessarily have to wait until Medicare's Annual Enrollment Period to review your Medicare Supplement coverage.

Does Kentucky have the Medicare Supplement Birthday Rule?
Yes! Kentucky's Birthday Rule took effect January 1, 2024. Eligible Medicare Supplement policyholder can apply to a different insurance company for the same lettered plan during the 60-day period beginning on their birthday.
Can I switch from Medicare Supplement Plan G to Plan N using the Indiana Birthday Rule?
Not with guaranteed-issue protection under Indiana's Birthday Rule. Indiana requires applicants using this protection to maintain the same lettered Medicare Supplement plan, including the applicable variation. You may still apply for another plan through regular underwriting or qualify under another guaranteed-issue right.
Can I use the Birthday Rule every year?
In states such as Indiana and Kentucky, eligible Medicare Supplement policyholders have an annual birthday-related opportunity. Eligibility and timing must be verified under the applicable state law.

However, if your Medicare Supplement premiums are becoming too expensive overall, a Medicare Advantage plan may be worth exploring. You can make this change during this timeframe.
