Medicare Enrollment Periods Explained
A Simple Guide for Texans
The most critical requirement for obtaining Medicare benefits exists in understanding Medicare enrollment periods.
The timing of your enrollment is determined by your current age, which includes 65 years, your work status beyond 65 years; your upcoming retirement date; and your existing Medicare coverage.
- The enrollment period starts
- The plan modification date
- The late penalty assessment
- The start date of your coverage
Initial Enrollment Period (IEP)
This applies when you turn 65.
Your Initial Enrollment Period is a 7-month window:
- 3 months before your 65th birthday
- Your birthday month
- 3 months after
During this time, most people enroll in:
- Medicare Part A
- Medicare Part B
- Part D (prescription coverage)
- Or a Medicare Advantage plan (Must have A and B)
Missing this window may lead to permanent late enrollment penalties unless you have creditable work coverage.
If you’re turning 65 in Texas and unsure what applies to you, start with a question.
Special Enrollment Period (SEP)
If you’re still working past 65 and have employer coverage, you may qualify for a Special Enrollment Period.
When employer coverage ends, you typically have:
- 8 months to enroll in Part B
- 2 months to enroll in Part C or Part D
This is one of the most common areas where mistakes happen.
We help Texans coordinate Medicare with retirement to avoid gaps and penalties.
Annual Enrollment Period (AEP)
October 15 – December 7
During AEP, people already on Medicare can:
- Switch Medicare Advantage plans
- Move from Advantage to Original Medicare
- Change Part D prescription plans
Changes take effect from January 1.
This is when many Texans review their coverage if costs or provider networks change.
Medicare Advantage Open Enrollment Period (OEP)
January 1 – March 31
This period only applies if you are already enrolled in a Medicare Advantage plan.
You may make one change:
- Switch to another Advantage plan
- Return to Original Medicare
This is a limited one-time adjustment period.
Medigap Enrollment Rules in Texas
If you enroll in a Medigap (Medicare Supplement) plan during your initial 6-month window after enrolling in Part B, you typically do not have to answer health questions.
Outside that window, answering health questions may apply unless you qualify for a special protection.
Understanding this is critical before switching plans.
Why Enrollment Periods Are Confusing
Two people with the same Medicare plan may have completely different rights to change coverage, depending on timing and life circumstances.
That’s why we always recommend:
Before switching plans, find out If a change is allowed.
