Quick Answer

When should you sign up for Medicare?

Most people get a 7-month Initial Enrollment Period around their 65th birthday. It starts 3 months before the month you turn 65, includes your birthday month, and ends 3 months after.

During this window, you may need to enroll in Medicare Part A, Part B, Part D, Medicare Advantage, or Medicare Supplement depending on your situation.

If you are still working or covered through a spouse’s employer plan, your decision may be different. Before delaying Part B or Part D, confirm whether your employer coverage is considered creditable and whether you can delay Medicare without penalties.

Enrollment Timing

Your 7-month Medicare Initial Enrollment Period

For most people, the Medicare Initial Enrollment Period is the first major deadline to understand.

3 months before Start comparing
Birthday month Confirm effective dates
3 months after Enrollment window ends

If your birthday is on the 1st day of the month, your Medicare timing may start earlier. If you already receive Social Security benefits, you may be enrolled in Medicare automatically. If you are still working, your decision may depend on your employer coverage.

Checklist

Turning 65 Medicare checklist

Three things to confirm before you enroll, delay, or choose a plan.

1

Confirm your Part A and Part B timing

Know your 7-month Initial Enrollment Period dates and whether you need to enroll now or can delay without a penalty.

2

Check employer coverage, HSA, and drug coverage rules

If you are still working, confirm employer size, whether your drug coverage is creditable, and whether HSA contributions are affected.

3

Compare plans before your effective date

Review Medicare Advantage, Medicare Supplement, and Part D options before your Medicare start date — not after.

Still Working?

Turning 65 and still working?

If you or your spouse are still working and you have employer coverage, do not assume you should automatically take or delay Medicare Part B. The right answer can depend on employer size, whether the coverage is active employer coverage, whether your drug coverage is creditable, and whether you contribute to an HSA.

Before delaying Medicare, ask:

  • Is my employer coverage based on current employment?
  • Does the company have 20 or more employees?
  • Is my prescription coverage creditable?
  • Do I contribute to an HSA?
  • Will Medicare become primary or secondary?
  • What happens when I retire?

Avoid Costly Mistakes

The three Medicare mistakes that cost people the most

These are not obscure edge cases. They happen to people turning 65 every day.

1

Delaying Part B on COBRA, retiree, or small-employer coverage

COBRA, retiree coverage, and Marketplace plans do not allow a penalty-free Part B delay. Neither does coverage from an employer with fewer than 20 employees. This mistake can mean a permanent 10% penalty per year and uncovered claims.

2

Triggering the retroactive Part A and HSA trap

If you enroll in Medicare after 65, Part A can start retroactively up to 6 months. If you were contributing to an HSA during that period, you may owe IRS tax penalties. Stop contributions at least 6 months before any Medicare enrollment.

3

Waiting until your Medicare effective date to choose a plan

Your Medicare Advantage, Part D, or Supplement plan needs to be selected and submitted before your Medicare effective date — not after. Waiting until the last moment can leave you without drug coverage or force you into a less competitive plan.

Review My Situation Before I Make a Mistake

Big Decision

Advantage or Supplement?

This is one of the most important choices you make when starting Medicare. Medicare Advantage may appeal to people who want lower monthly premiums, bundled drug coverage, and extra benefits. Medicare Supplement may appeal to people who want broader provider access, more predictable medical costs, and the ability to see any provider who accepts Medicare.

Compare Paths

Should you choose Medicare Advantage or Medicare Supplement when turning 65?

There is no one right answer for everyone. Your best fit depends on doctors, prescriptions, pharmacy, travel, monthly premium comfort, and how you prefer to pay for care.

Common Questions

Turning 65 Medicare questions

For many people, the Medicare Initial Enrollment Period begins 3 months before the month they turn 65, includes their birthday month, and ends 3 months after. If your birthday is on the first day of the month, your timing may start earlier.
When turning 65, you should know your enrollment dates, decide whether you need Part A and Part B, review employer coverage if you are still working, compare Medicare Advantage and Medicare Supplement, consider Part D drug coverage, and check your doctors and prescriptions before choosing a plan.
Not always. Some people enroll at 65, while others may be able to delay certain parts of Medicare if they have qualifying employer coverage. You should verify your situation before delaying Part B or Part D.
It depends on your employer coverage, whether the coverage is based on current employment, employer size, whether your drug coverage is creditable, and whether you contribute to an HSA. Do not assume you should automatically enroll or automatically delay.
If you miss the wrong enrollment window and do not have qualifying coverage, you may face delayed coverage and possible late enrollment penalties. The rules can differ depending on whether you are still working and what coverage you have.
If you are still working and covered by current employer coverage, your Part B timing may depend on employer size and whether Medicare would be primary or secondary. Check with your employer benefits administrator before delaying Part B.
If you are already receiving Social Security benefits before 65, you may be automatically enrolled in Medicare. If you are not receiving Social Security benefits, you may need to enroll yourself.
Your Medicare start date depends on when you enroll and your birthday timing. If you enroll before your birthday month, coverage often starts the month you turn 65, but special rules can apply if your birthday is on the first day of the month.
Even if you do not take prescriptions now, you should understand Part D and creditable drug coverage. Going without creditable drug coverage can lead to a late enrollment penalty if you enroll later.
One of the biggest mistakes is waiting too long to understand your deadlines and coverage choices. Missing enrollment windows, delaying Part B incorrectly, ignoring Part D, or picking a plan without checking doctors and prescriptions can create problems.
Yes. Lehigh Partners Senior Benefits can help compare Medicare Advantage, Medicare Supplement, and Part D options based on your doctors, prescriptions, pharmacy, ZIP code, budget, and coverage preferences.
