Most people should apply for Medicare three months before their 65th birthday. That gives you the earliest possible coverage start and avoids gaps or late penalties.
The short answer is three months before you turn 65. That is the opening of your Initial Enrollment Period, and applying then means your coverage starts on the first day of your birthday month with no delays.That said, not everyone needs to rush to sign up at 65. If you are still working and covered by an employer health plan through your job or your spouse's job, you may be able to delay Part B without a penalty. The key word is employer coverage. Coverage through COBRA, a retiree plan, or the health insurance marketplace does not count, and delaying because of those could trigger a lifetime late enrollment penalty.If you are already receiving Social Security benefits before you turn 65, you will likely be enrolled in Medicare automatically and get a card in the mail about three months before your birthday. In that case, there is nothing extra you need to do unless you want to delay Part B.For people not yet receiving Social Security, you need to actively apply, either online at SSA.gov, by phone, or at a local Social Security office. Do not wait for something to arrive in the mail if you have not started Social Security yet.The worst outcome is missing your window without qualifying coverage in place, because the late penalty for Part B adds 10 percent to your premium for every 12-month period you delayed, and that extra cost lasts for life.
If you are unsure whether your current coverage qualifies as a valid reason to delay, the Utah ADRC (the state's free Medicare counseling program, also called SHIP) can review your situation at no cost.
For you, this means putting a reminder on your calendar three months before your 65th birthday and taking action then, unless you have confirmed employer coverage that lets you delay safely.
Our Commitment to Reliable Medicare Information
At Resting Sycamore Advisors, we work to provide accurate, current, and trustworthy information about Medicare Advantage, Medicare Part D, and Special Needs Plans.
To do that, we use data published by the Centers for Medicare & Medicaid Services (CMS), which is the official source for Medicare plan and enrollment information.
Our Medicare plan pages and comparison tools are powered by CMS datasets, including:
When possible, we link to the original CMS resources so you can review the source material directly.
We follow the CMS release schedule and update our website as new data becomes available.
We load new plan year Landscape and PBP files before the Medicare Annual Enrollment Period (October 15 through December 7). We also monitor CMS.gov for updates or revisions and refresh our content when needed.
We update enrollment and performance data as CMS publishes revised files, which are typically released monthly or quarterly.
We routinely monitor CMS announcements for corrections, reissued files, or other changes and update our pages accordingly.
Each plan page includes a Last Accessed date so visitors can see when the source information was most recently reviewed.
CMS data can be difficult to read in raw form. To make it easier to use, we format and organize the data for clarity.
This includes:
All data values come from CMS. We do not change the underlying values beyond formatting, organization, and presentation.
We keep internal records of the CMS dataset versions used on our site.
If CMS issues corrected or revised files, we update our website to reflect the latest available version.
