The short version: your Initial Enrollment Period around age 65

If you are approaching 65 in Charlotte or anywhere in North Carolina, the most important window to know is your Initial Enrollment Period (IEP). It is 7 months long: it starts 3 months before the month you turn 65, includes your birthday month, and ends 3 months after your birthday month. Signing up during your IEP is what lets you avoid the late-enrollment penalties discussed below, so this is the window most people should plan around.

When your coverage actually starts depends on when in that window you enroll:

  • If you sign up during the 3 months before your birthday month, coverage generally starts the first day of your birthday month, so you can be covered the moment you turn 65.
  • If you sign up during your birthday month or the 3 months after, coverage starts the first day of the month after you sign up, which can leave a gap.

The practical takeaway: because signing up early is what lets coverage begin right at 65, it is worth starting your research and paperwork about 3 months before your birthday month rather than waiting until the last minute.

What if you are still working past 65?

Many people in the Charlotte area keep working past 65 and stay on an employer health plan. If you or your spouse have group health coverage through active employment, you can generally delay Part B without penalty and get a Special Enrollment Period (SEP) to sign up while you are still working, or within 8 months of the employment or that coverage ending.

This is an area where a small mistake can be expensive, because the rules differ depending on employer size and whether the coverage is truly "active" versus retiree or COBRA coverage. If you are in this situation, it is worth confirming your exact timeline before you assume you can safely delay.

The other enrollment windows to know

General Enrollment Period (GEP)

The GEP runs January 1 to March 31 every year. It is a fallback for people who missed their IEP and do not qualify for a Special Enrollment Period. Coverage starts the first day of the month after you sign up, and a late-enrollment penalty may apply.

Annual Enrollment Period (AEP) — Medicare Open Enrollment

The AEP runs October 15 to December 7 every year. During this window, anyone with Medicare can join, drop, or switch a Medicare Advantage plan; add, drop, or switch a Part D drug plan; or move between Original Medicare and Medicare Advantage. Changes take effect January 1 of the following year, and your request must be received by December 7. This is the once-a-year window The Jordan Insurance Agency uses to review your plan against next year's options, because plans, drug formularies, and provider networks change every year.

Medicare Advantage Open Enrollment Period (MA OEP)

The MA OEP runs January 1 to March 31 every year and is only for people already enrolled in a Medicare Advantage plan. You may make one change: switch to a different Medicare Advantage plan, or drop Medicare Advantage and return to Original Medicare (and add a Part D drug plan). It does not apply to people in Original Medicare.

Special Enrollment Periods (SEPs)

SEPs let you enroll or change coverage outside the normal windows when certain life events happen, usually without a late penalty. Common ones include:

  • Working past 65 with employer coverage, as described above.
  • Moving to a new address outside your plan's service area, or to a new area with different plan options.
  • Loss of other coverage, such as employer, union, or other creditable coverage.
  • The 5-Star Special Enrollment Period, which lets you make a one-time switch into a Medicare Advantage plan, Part D plan, or Medicare Cost plan with a 5-star CMS quality rating if one is offered in your area. This SEP runs December 8 through November 30 of the following year.

There are many other SEPs (for example, qualifying for Extra Help). For situations not listed here, check Medicare.gov or call 1-800-MEDICARE.

The Medigap window is separate — and timing matters

If you are considering a Medicare Supplement (Medigap) policy to pair with Original Medicare, there is a separate window that is easy to overlook. Your Medigap Open Enrollment Period is 6 months long and starts the first month you have both Medicare Part B and are 65 or older. During this one-time window you have guaranteed issue rights: an insurance company cannot turn you down, cannot use medical underwriting (no health questions used to deny you), and cannot charge you more because of pre-existing conditions.

After this 6-month window ends, insurers generally can use medical underwriting and may deny you or charge more, unless you have a separate guaranteed issue right. That is why timing a Medigap decision correctly matters so much, and why it helps to review it before the window closes rather than after.

What happens if you enroll late

Missing your enrollment window can create penalties that, in some cases, last for life. Here is what to know:

  • Part A late penalty: Most people get premium-free Part A and owe no penalty. If you have to buy Part A and sign up late, the monthly premium may go up 10%, and you pay that higher premium for twice the number of years you could have had Part A but did not. It is not lifelong.
  • Part B late penalty: If you do not sign up when first eligible and do not qualify for an SEP, your Part B premium goes up 10% for each full 12-month period you could have had Part B but did not. This penalty lasts for as long as you have Medicare. For reference, the standard Part B premium is $202.90 per month in 2026, before any penalty and before higher-income adjustments.
  • Part D (drug coverage) late penalty: If you go 63 or more days in a row without Part D or other creditable drug coverage after your IEP, you may owe a penalty. It is calculated as 1% of the national base beneficiary premium ($38.99 in 2026) for each full month you went without coverage, rounded to the nearest 10 cents, added to your monthly drug-plan premium, and it lasts for as long as you have Medicare drug coverage.
