Medicare Part A, B, C and D Explained in Plain English

Frequently Asked Questions About Medicare

Can I change my Medicare coverage every year?

Yes. You can switch between Medicare Advantage plans or change your Part D drug coverage annually during Open Enrollment from October 15 to December 7.

Switching from Medicare Advantage back to Original Medicare with a Medigap policy may require medical underwriting if you are outside your initial guaranteed-issue window.

What happens if I keep working past age 65?

If your employer has 20 or more employees, your group health plan remains primary to Medicare. You can delay Part B without penalty until that employment ends.

Confirm with your benefits administrator that your job coverage qualifies as creditable before delaying enrollment, as COBRA and retiree plans do not qualify.

Does Medicare cover routine dental, vision, and hearing care?

Original Medicare excludes routine dental exams, cleanings, eyeglasses, and hearing aids from coverage.

Many Medicare Advantage plans offer supplemental allowances for these routine services, or you can purchase separate private dental and vision policies.
