Congratulations — and Take a Breath
Turning 65 and approaching Medicare can feel overwhelming. There are decisions to make, windows to hit, and penalties to avoid. But the process is manageable — especially with a local licensed agent guiding you through it. This page walks you through everything you need to do and when.
Step 1 — Know Your 7-Month Window
Your Initial Enrollment Period (IEP) is 7 months long: the 3 months before your birthday month, your birthday month, and the 3 months after. Enrolling in the first 3 months — before your birthday month — means your coverage starts on the first day of your birthday month, giving you the smoothest transition.³
Start 4–5 months early: Begin your Medicare research 4–5 months before your 65th birthday. This gives you time to understand your options, compare plans, and enroll without rushing.
Step 2 — Decide About Your Current Coverage
What you need to do at 65 depends entirely on your current health coverage situation. Find your scenario below — each one has a different rule and a different right answer.
Action: Enroll in Medicare Parts A and B during your Initial Enrollment Period. Then choose either a Medicare Advantage plan or Original Medicare with a Medigap policy and Part D. Do not delay — there is no qualifying reason to.
Action: You may delay Medicare Part B without penalty while your employer coverage is active — your group plan is the primary insurer. Get written confirmation from your HR department that your coverage is considered creditable. Enroll within 8 months of losing that coverage when the time comes.
Action: Enroll in Medicare at 65 regardless of your employer coverage. Once you turn 65, Medicare becomes your primary insurer — your employer plan becomes secondary. Delaying Part B in this situation will trigger the permanent late enrollment penalty. Do not assume your group plan protects you here.
Action: Enroll in Medicare at 65. Retiree health plans are almost always designed to be secondary to Medicare — meaning Medicare pays first and your retiree plan covers what remains. Skipping Medicare could leave significant gaps in your coverage and may even invalidate your retiree plan benefits.
Action: Enroll in Medicare during your Initial Enrollment Period. COBRA does not count as qualifying coverage for the purpose of delaying Medicare — this is one of the most common and costly mistakes new Medicare enrollees make. Staying on COBRA past your IEP will trigger permanent Part B and Part D penalties.
Not sure which scenario applies to you? This is exactly the conversation to have with a local agent before your window opens. Getting this wrong means a penalty that lasts as long as you have Medicare.
Step 3 — Understand Your Three Main Path Options
Path 1: Medicare Advantage
Enroll in Parts A and B, then choose a Medicare Advantage plan that bundles A, B, drug coverage, and often dental/vision. Many plans have low or no additional premium. Best for people with stable local provider relationships.
Path 2: Original Medicare + Medigap + Part D
Enroll in Parts A and B, add a Medigap supplement policy (during your guaranteed 6-month window), then add a Part D drug plan. Higher monthly cost but maximum flexibility and predictable expenses. Best for frequent travelers and people who want to see any Medicare provider.
Path 3: Original Medicare + Part D Only
Enroll in Parts A and B plus Part D, with no supplemental coverage. Lowest initial cost but exposes you to the unlimited 20% coinsurance under Part B. Generally only appropriate for people with very limited budgets who are in excellent health.
Step 4 — The Medigap Window You Cannot Miss
If you choose Path 2, you have a critical 6-month window starting the month your Part B begins in which you have guaranteed acceptance for any Medigap plan sold in your state — regardless of your health history. After this window closes, insurers can deny you or charge more based on health conditions. Do not delay Medigap enrollment.
Step 5 — How to Actually Sign Up
You sign up for Medicare Parts A and B through the Social Security Administration. If you are already receiving Social Security benefits, you are likely enrolled automatically. If not, you need to apply during your IEP through Social Security. Your Part D plan, Medicare Advantage plan, or Medigap policy is then selected with the help of your agent and enrolled directly with the insurance company.
A Local Agent Makes This Significantly Easier
The decisions you make at 65 set the foundation for years of healthcare coverage. A local independent agent who represents 29 carriers has no incentive to push any particular plan — their only job is to find the right fit for your specific doctors, medications, and budget. Most people who work with an independent agent feel significantly more confident in their enrollment decisions.
