Medicare General Enrollment Period

Medicare General Enrollment Period

Navigating the world of Medicare can feel overwhelming, especially with all the different enrollment periods. One important period to understand is the Medicare General Enrollment Period (GEP). So, what is the Medicare General Enrollment Period? This specific timeframe can be a lifeline for those who missed their initial enrollment window or special enrollment periods. 

Let’s dive in and explore what the Medicare General Enrollment Period is when it happens, and why it matters for your healthcare coverage.

Start with Understanding the Medicare General Enrollment Period

The Medicare General Enrollment Period runs annually from January 1 to March 31. During this time, individuals who didn’t sign up for Medicare Part A and/or Part B when they were first eligible have another chance to enrol. However, it’s essential to note that this isn’t an open season for all Medicare plans—this period specifically applies to those who need to enrol in Original Medicare (Part A and Part B).

Why Is the General Enrollment Period Important?

Missing your Initial Enrollment Period (IEP) can lead to significant gaps in healthcare coverage and, in some cases, late enrollment penalties. The General Enrollment Period offers a crucial opportunity to get back on track. Enrolling during this time ensures that your coverage begins on July 1 of the same year. While it means you might still face a delay in receiving benefits, it prevents further penalties and coverage gaps.

Who Needs to Use the General Enrollment Period?

Typically, the General Enrollment Period is used by individuals who didn’t sign up for Medicare Part A and/or Part B during their Initial Enrollment Period and who aren’t eligible for a Special Enrollment Period (SEP). For instance, if you didn’t enrol because you were still working and had employer-sponsored insurance, you might qualify for a Special Enrollment Period once that coverage ends. But if you missed that window too, the General Enrollment Period becomes your next option.

Late Enrollment Penalties

It’s crucial to be aware that enrolling late in Medicare Part A and/or Part B can result in penalties. For Part B, the penalty is an increase in your premium by 10% for each full 12-month period that you could have had Part B but didn’t sign up. This penalty is not a one-time fee—it lasts as long as you have Part B. For Part A, if you have to buy it, the penalty could increase your premium by 10% as well, and you’ll have to pay that higher premium for twice the number of years you could have had Part A but didn’t sign up.

How to Enroll During the General Enrollment Period

Enrolling in Medicare during the General Enrollment Period is relatively straightforward. You can sign up by visiting your local Social Security office, calling Social Security at 1-800-772-1213, or applying online at the Social Security website. Remember, any changes or new coverage won’t take effect until July 1, so plan accordingly to avoid any coverage gaps.
