Medicare Basics

Understanding Medicare doesn’t have to be confusing. We’ve gathered the things you need to know and resources to help you find plans that work for you.


What is Medicare

Medicare was established in 1965 to help people who are 65 and over or have certain disabilities or conditions pay for the rising costs of medical care. You are eligible if:

  • You are age 65 or above.
  • You already receive Social Security or Railroad Retirement Board (RRB) benefits
  • You have been diagnosed with end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS, “Lou Gehrig’s disease”)
  • You are under age 65 and are permanently disabled and have received Social Security disability payments for at least 24 months.

Deciding The Plan for You

Medicare Advantage vs Medicare Supplement
  • Medicare Advantage 2024

    Medicare Advantage

    Medicare Advantage combines Original Medicare and sometimes Prescription Drug Plans (Part D) for an all-in-one solution with extra perks. These plans are good for:

    • People who want to keep costs more predictable
    • People who wish to see their established, in-network care team
    • People who want extra benefits
  • medicare-sup-image-original

    Medicare Supplement

    Medicare Supplement plans, or Medigap, provide extra insurance for the things Original Medicare doesn’t cover. These plans are typically good for:

    • People who want coverage that travels with them
    • People who want more flexibility and choice in providers
    • People with budget flexibility

When is My Enrollment Period?

Your Initial Enrollment Period (IEP) is based on your birth month. Enrollment begins three months before you turn 65 and extends until three months after.

If you miss the IEP there is also the Special Enrollment Period (if you qualify) and the General Enrollment period.

Each year, you can change your plan options during the Annual Enrollment Period (AEP) from October 15 to December 7.

Medicare FAQs

  • 1. You can choose Original Medicare. If you want prescription drug coverage, you must join a Medicare Prescription Drug Plan (Part D).
    2. You can choose to join a Medicare Advantage plan (like an HMO or PPO). Most Medicare Advantage plans include prescription drug coverage.
  • Medicare doesn't cover everything. If you need certain services that aren't covered under Medicare Part A or Part B, you'll have to pay for them yourself. Medicare generally does not cover items such as dental care, eye exams, hearing services, and outpatient prescription drugs.
  • All of these plans help cover healthcare expenses not covered by Medicare. MA plans include your Original Medicare benefits and other benefits in one plan. If you join an MA plan, you will use one member ID card for your healthcare and prescription drug needs. You do not need an additional Medicare plan. You can choose either a Medicare Advantage or a Medicare Supplement plan but not both. MA plans generally have lower out-of-pocket costs and offer health and wellness benefits.

  • Prescription drug costs can add up quickly and many people need financial assistance covering some of the costs. If you meet certain income requirements, you could be eligible for Medicare's assistance program, Extra Help.

    To see if you qualify for Extra Help, contact Medicare, the Social Security Administration, or your state Medicaid office.

  • To be eligible for either a Medicare Advantage or a Medicare Supplement plan, you must reside in the plan’s service area, have Medicare Part A and Part B and continue to pay your Part B premiums (and Part A, if applicable) unless otherwise paid for by a third party. To be eligible for a Medicare Part D plan, you must be enrolled in Part A and/or Part B and you don’t have other drug coverage (creditable coverage).
  • This is coverage that pays as much as or more than Medicare's standard prescription drug coverage. If you have prescription drug coverage through your employer, it may be creditable (contact your benefits administrator or human resources contact to find out). That means, if you decide to switch to a stand-alone prescription drug plan later, you would not have to pay the Part D late enrollment penalty (LEP). If your coverage is not creditable, you may have to pay the Part D LEP.
