Medicare 101

Everything You Need to Know

Medicare is your health insurance once you turn 65. It's a federal program that helps cover your medical costs. Like most healthcare plans, it doesn't cover everything, and costs can vary widely depending on your location and specific healthcare needs.

Medicare is a complex system with vast amounts of information and numerous options that can be difficult to navigate. Understanding the Medicare basics will help you make informed decisions about your healthcare and avoid costly mistakes.

This comprehensive Medicare guide is a different type of senior resource center. One that’s designed to help you worry less and live more.

How to Qualify for Medicare

See how to qualify for Medicare and when you can take advantage of it.

Who gets Medicare? It’s pretty straightforward. You qualify for Medicare if you:

  • Are 65 or older
  • Are under 65 with a qualifying disability (after receiving disability benefits for a minimum of 24 months)
  • Have end-stage kidney disease or ALS at any age

Most people become eligible at 65, regardless of whether they're still working or how much they earn.

Can green card holders get Medicare? Yes, green card holders who have lived in the U.S. for at least five years and meet the work requirements can qualify for Medicare, unless this has changed as of the current press time in the U.S.

Important Medicare Enrollment Dates

When and how you can sign up, switch plans, or make changes to your existing coverage throughout the year.

Automatic Enrollment: If you're already receiving Social Security benefits when you turn 65, you'll automatically be enrolled in Parts A and B. You'll receive your Medicare card in the mail.

Manual Enrollment: If you're not receiving Social Security, you need to actively participate in Medicare enrollment through Social Security (online, by phone, or in person). Many people work with a Medicare insurance agent to help navigate their options and ensure proper enrollment.

When to Enroll: Your Initial Enrollment Period is a 7-month window: 3 months before your 65th birthday month and 3 months after. Missing this window can result in late enrollment penalties and gaps in coverage.

Still Working at 65? If you have employer health insurance, you may be able to delay Medicare enrollment without penalties. However, the rules are complex, so check with your HR department and Medicare before making this decision.

Initial Enrollment: When you first become eligible (around your 65th birthday)

Annual Medicare Enrollment Dates (October 15 - December 7):

  • Change Medicare Advantage plans
  • Switch between Original Medicare and Medicare Advantage
  • Change prescription drug plans

Medicare Advantage Open Enrollment (January 1 - March 31):

  • Switch Medicare Advantage plans
  • Or return to Original Medicare

Missing deadlines can mean:

  • Late enrollment penalties that last as long as you have Medicare
  • Gaps in coverage
  • Limited ability to make changes later

Guide to Medigap

Medigap (Medicare Supplement Insurance) is private insurance designed to fill the "gaps" in Original Medicare coverage. Here's how it fits into the Medicare system:

Medigap is NOT a fifth part of Medicare. Instead, it's private insurance that works alongside Original Medicare (Parts A and B) to cover costs that Medicare doesn't pay.

Medigap only works with Original Medicare, never with Medicare Advantage. If you have a Medicare Advantage plan, you cannot have Medigap insurance, and vice versa.

Dive into more details on what Medigap covers, Medigap plan types, Medigap enrollment rules, and more in our Guide to Medigap.

Common Medicare Plan Options

There are lots of Medicare options, but we’ll break down the two most common plan combinations out there.Area Agencies on Aging are nonprofit agencies designated by states to address the needs of all seniors at the local level.

Option 1: Original Medicare (Parts A + B) + Separate Part D

  • More doctor choice and flexibility
  • Higher out-of-pocket costs with no annual limit
  • Need to add a separate prescription drug plan
  • May want to add a Medigap (supplement) policy for extra protection

Option 2: Medicare Advantage (Part C, usually includes Part D)

  • Lower out-of-pocket costs with annual spending caps
  • Often includes extras like dental and vision
  • Limited to the plan's network of doctors and hospitals
  • All-in-one convenience

Key Medicare Decision Points

How should you decide which Medicare plan is right for you or the senior in your life?

When deciding which option is right for you or the senior in your life, there are some important questions to consider:

  1. Would you consider switching doctors to lower your costs? Original Medicare offers broad provider access, even with a Medigap plan. Medicare Advantage may have network restrictions, but it could reduce expenses.
  2. Do you need dental or vision coverage? Original Medicare only covers dental and vision for specific medical needs. Some Medicare Advantage plans offer expanded benefits like exams, eyewear, and dental care.
  3. Do you travel frequently? Original Medicare provides nationwide coverage. Medicare Advantage plans may have network limits, but they often include worldwide emergency benefits.
  4. Do you have chronic conditions? Consider which path gives you better access to specialists.
  5. Do you need additional benefits, such as hearing or transportation? Medicare Advantage may include perks that Original Medicare doesn’t, such as hearing aids, wellness programs, or transportation.
  6. Are you aware of the Part D late enrollment penalty? Medicare encourages early enrollment to avoid gaps in coverage. Late enrollment adds a permanent monthly penalty to your Part D premium. You can enroll in a standalone Part D plan with Original Medicare or choose a Medicare Advantage plan that includes Part D coverage, whichever fits your needs.
  7. Do you anticipate high healthcare costs? Original Medicare does not have a maximum out-of-pocket (MOOP) limit, meaning there is no cap on the amount you may spend on covered services. Medicare Advantage plans, however, do include a Maximum Out-of-Pocket (MOOP) limit, ensuring that once you reach the annual limit, the plan covers 100% of approved costs for the remainder of the year.

Remember, you can make changes during the annual Medicare Open Enrollment Dates (October 15 - December 7), though some changes become more difficult to make as you age.

The most important thing is to enroll as soon as you're first eligible to avoid penalties and coverage gaps. When in doubt, speak with a licensed Medicare agent who can answer questions and help you compare specific plans in your area.

Medicare Costs

We’ll provide a general overview of what to expect from the four parts of Medicare coverage, with some variations depending on your location and enrollment choices.

Medicare costs vary significantly depending on your plan choices and where you live; however, we provide a general breakdown of some typical costs you can expect to encounter. It is essential to check your specific plan for exact costs by location, provider, or service.

Cost Sharing refers to the portion of healthcare expenses that beneficiaries must pay out of pocket, creating a shared financial responsibility between the individual and the Medicare program.

What Medicare Doesn't Cover

A few important things to be aware of as you first enter the Medicare world.

While Medicare covers a wide range of essential healthcare services, many individuals have coverage needs that extend beyond Original Medicare (Parts A and B). Here are a few common areas where you can explore added coverage through Medicare Part C:

  • Most dental care
  • Vision care (routine eye exams, glasses)
  • Hearing aids
  • Long-term care (nursing homes, assisted living)
  • Care outside the United States (care during international travel)
  • Cosmetic surgery
  • Most alternative medicine
  • Allowances for over-the-counter items, food, utilities, wellness, and/or healthcare expenses
  • Preventive and healthy living services

Coverage depends on which Part C plan you enroll in. Please confirm benefit details before enrolling in a specific plan.

One of the most common questions we get: Does Medicare pay for senior living?

Unfortunately, Medicare provides little to no coverage for senior living options. It only covers short-term skilled nursing care after a hospital stay, not ongoing assisted living or memory care. 

Many families are surprised to learn that some assisted living facilities accept Medicaid, which may be an option for those who qualify financially, as Medicaid can help cover long-term care costs that Medicare doesn't cover. This is one of many important distinctions between the two often-confused but very different insurance plans.

Home Care and Medicare

Many seniors prefer to age at home, and there are several benefits of home care that Medicare may help cover. Does insurance cover home care? Medicare covers home health services when you're homebound and need skilled nursing, physical therapy, or other skilled care services. However, Medicare doesn't cover private aide services or custodial care.

Home nursing care costs can be significant when paid privately, so it is important to understand what Medicare covers. Medicare may cover skilled home health services, but families often need to supplement these with private care for daily living assistance.

Additional Considerations for Seniors

Many seniors benefit from exploring senior discounts available through Medicare Advantage plans or community programs. These can include fitness memberships, transportation services, and other wellness benefits.

For families concerned about care quality, it's essential to know that if problems arise in nursing facilities, a nursing home negligence lawyer can help protect residents' rights and ensure proper care standards are maintained and/or enforced.

Medicaid vs Medicare

What’s the difference, and how to remember.

It's important to understand the difference between Medicaid and Medicare. Medicare is primarily based on age or disability, while Medicaid is an income-based assistance program that can work in conjunction with Medicare for those who qualify financially.

Helpful tip: MedicAID is based on income, while MediCARE is usually based on age

Associating the 'i' in' Aid 'with the' i' in 'Income' and the 'A' in 'Care' with the 'A' in 'Age' has been a useful reminder.  🙂
