After losing employer health coverage, you generally have 8 months to sign up for Medicare Part B without a late penalty. This is called a Special Enrollment Period.
When you are covered by an employer health plan based on your own or a spouse's current employment, you can delay Medicare Part B without penalty. But once that coverage ends, a clock starts. You have 8 months from the date that employer coverage ends to enroll in Part B without facing a late enrollment penalty.A few things worth knowing about this window. First, it starts when the employment or the coverage ends, whichever comes first. Second, do not wait until the last week of that 8-month window if you want continuous coverage. Medicare Part B coverage after a Special Enrollment Period typically starts the first of the month after you apply. Waiting too long can create a gap.COBRA and retiree health coverage do not count as employer coverage for this purpose. If you lose your job-based plan and switch to COBRA, the 8-month clock is already running. COBRA does not pause or reset it.If you miss the 8-month window, you may have to wait for the General Enrollment Period, which runs January through March each year, with coverage starting July 1. You could also face a permanent late enrollment penalty added to your Part B premium. Avoiding that penalty is one of the best reasons to act quickly after losing employer coverage.Always confirm your specific situation with Social Security or a Medicare counselor, since enrollment rules can be complex.
In Utah, the Aging and Disability Resource Centers (ADRC) offer free Medicare counseling and can help you understand your enrollment window and avoid costly mistakes when transitioning off employer coverage.
For you, this means 8 months sounds like plenty of time, but acting sooner rather than later protects you from coverage gaps and a penalty that would follow you for as long as you have Medicare.
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.
