What it is
The Medigap birthday rule is a name people use for a state law that gives current Medigap policyholders a short window each year to change plans. The window is usually tied to the person's birthday. During it, a person may be able to move to a different plan without the usual medical underwriting.
Outside of special windows, a company in most states may ask health questions when you apply for a new Medigap plan. It may then accept, decline or price the plan based on your answers. A birthday or anniversary rule is one way some states limit that.
These rules are set by each state, so they vary. Some states have a birthday rule, some use an anniversary date, and others have no such rule. Massachusetts, Minnesota and Wisconsin also standardize Medigap differently from most states. Details can change over time, so always confirm current rules.
How it’s traditionally been approached
People have traditionally looked at the birthday rule when their current plan no longer feels like the right fit. A premium change, a new health need or a wish for different coverage are common reasons. Others simply like to review their options once a year.
The rule often comes with conditions. A state may only allow a switch to a plan with the same or fewer benefits. It may also limit the window to a set number of days after the birthday. The exact conditions depend on the state.
Many people start by checking with Medicare.gov or their State Health Insurance Assistance Program (SHIP). Some also talk with a licensed agent. Neither route is wrong. It comes down to how much help a person wants.
How the right licensed agent may help
A Medigap agent may help you find out whether your state has a birthday rule and whether it could apply to you. Agents who work with many carriers may also be able to explain how plans compare. Nothing here is a promise that a switch is possible or that it will lower your costs.
A visit or call is usually a relaxed conversation. You might be asked which Medigap plan letter you have now, what you like or dislike about it, and your birthday. Having your current policy and Medicare card nearby can help.
Good questions to ask include: Does my state have a birthday or anniversary rule? How long is the window? Can I move only to the same or fewer benefits? What happens if I miss the window? Call 1-800-MEDIGAP for more information.
The bigger picture
Insurance choices can weigh on the mind. Wondering whether you are in the right plan, or whether you can change it, may add stress. Knowing there may be a set time to review your options can bring some calm.
A plan that fits your health, budget and comfort level may help you feel more at ease about care. If you also want to think about wellness more broadly, Providers.plus may be a helpful place to explore. Take your time and involve someone you trust.
Keep in mind
- Not every state has a birthday rule, and the length of the window and its conditions vary by state.
- Missing the window may mean answering health questions later, and a company may decline or price a plan based on the answers.
- Plan letters matter. Plans C and F are available only to people who became eligible for Medicare before January 1, 2020, and Plan H was discontinued and is not sold today.
- This is education only, not insurance, legal, tax or medical advice. Confirm current rules at Medicare.gov, with your SHIP, or with a licensed agent.

Frequently asked questions
What is the Medigap birthday rule?
The Medigap birthday rule is a state rule that lets some current Medigap policyholders switch plans during a window around their birthday without health questions. It does not exist in every state. Check with your state's SHIP or Medicare.gov for current details.
Which states have a Medigap birthday rule?
The states with a birthday or anniversary rule change over time, so no list here is a safe one to rely on. Several states have some version of it, and the details differ. Confirm with Medicare.gov, your SHIP or a licensed agent.
How long is the Medigap birthday rule window?
The length of the window depends on your state. It is usually a limited number of days that starts around your birthday or policy anniversary. Ask your SHIP or a licensed agent for the current window in your state.
Can I switch to any Medigap plan under the birthday rule?
Not always. Many states only allow a switch to a plan with the same or fewer benefits than your current one. Plan availability also depends on when you became eligible for Medicare, since Plans C and F are limited to people eligible before January 1, 2020.
What happens if I miss my Medigap birthday rule window?
If you miss it, you may need to wait for the next year's window, if your state has one. In the meantime, a company may ask health questions and could decline or price a plan based on your answers. Other special rights, such as guaranteed issue, may apply in certain situations.
Is the Medigap birthday rule the same as open enrollment?
No. The Medigap open enrollment period is a separate window that starts when you are 65 or older and enrolled in Medicare Part B. The birthday rule is a state rule for people who already have a Medigap plan. Call 1-800-MEDIGAP for more information.
