Your Medicare Initial Enrollment Period is a 7-month window around your 65th birthday when you can first sign up for Medicare Parts A and B. Missing it can mean late enrollment penalties and gaps in coverage.
The Initial Enrollment Period, often called the IEP, lasts seven months total. It starts three months before the month you turn 65, includes your birthday month, and ends three months after. So if you turn 65 in June, your window runs from March through September.When you sign up within that window matters. If you enroll in the three months before your birthday month, your coverage can start the month you turn 65. If you wait until your birthday month or after, your start date gets pushed back. Waiting until the final months of your IEP can mean a two or three month delay before coverage actually begins.Most people who are already receiving Social Security benefits get enrolled in Part A and Part B automatically. If that's you, you'll get a Medicare card in the mail before you turn 65. If you're not yet collecting Social Security, you'll need to sign up yourself, through Social Security's website, by phone, or in person.Part A (hospital coverage) is premium-free for most people, so there's little reason to delay it. Part B (outpatient and doctor coverage) has a monthly premium. Some people with employer coverage through a current job choose to delay Part B, but that decision has rules and consequences worth understanding before you make it. Talking with a licensed Medicare agent before your IEP closes is a smart move.
Utah residents can get free one-on-one help understanding their enrollment options through the Aging and Disability Resource Centers (ADRC), which is Utah's State Health Insurance Assistance Program (SHIP). They can walk you through your timeline and help you avoid costly mistakes.
For you, this means the months around your 65th birthday are the most important window to pay attention to, and acting before it closes can protect you from penalties and coverage delays.
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.
