The Ultimate Guide to Understanding Medicare

Published: Dec 30, 2022. Last Updated: Jan 8, 2023.

If you're new to Medicare or considering enrolling in the program, it's important to understand the different types of coverage available and how to enroll. Medicare is a federally funded insurance program that provides healthcare coverage for those over the age of 65, as well as some younger individuals with disabilities.

It can be overwhelming to navigate the various options and requirements, but this guide is here to help you understand the basics and make informed decisions about your healthcare coverage. We'll cover the different types of Medicare plans, how to enroll, what's covered under each plan, and additional resources to help you stay up to date with your coverage.

Whether you're just starting to research your options or you're ready to enroll, this guide will provide you with the information you need to make informed decisions about your healthcare coverage.

Types of Medicare Plans

Understanding the different types of Medicare plans available to you is essential in making informed decisions about your healthcare coverage.

Original Medicare

Original Medicare, also known as traditional Medicare, consists of two parts: Part A and Part B. Part A covers hospital insurance, including inpatient care in hospitals and skilled nursing facilities, hospice care, and some home health services. Part B covers medical insurance, including doctor's visits, ambulance, and preventative services.

Medicare Advantage

Medicare Advantage, also known as Part C, is an alternative to Original Medicare. Medicare Advantage plans are offered by private insurance companies and must cover at least the same benefits as Original Medicare. However, some Medicare Advantage plans may offer additional coverage, such as vision, dental, and hearing services. Medicare Advantage plans may have lower out-of-pocket costs than Original Medicare, but they also often have stricter rules for receiving care, such as requiring a referral to see a specialist.

Medicare Part D

Medicare Part D[1] is a separate prescription drug coverage plan that can be added to Original Medicare or a Medicare Advantage plan. It covers prescription medications and can help lower the cost of your medication expenses.

It's important to carefully consider your healthcare needs and budget when deciding which type of Medicare plan is right for you. Original Medicare may offer more flexibility in terms of where you can receive care, but it also often has higher out-of-pocket costs. Medicare Advantage plans may have lower costs, but they may not cover all the same benefits as Original Medicare and may have more restrictions on care. It's also worth noting that you can enroll in a Medicare Advantage plan or Medicare Part D plan only during certain enrollment periods, so it's important to be aware of these deadlines.

Take the time to carefully consider your needs and budget, and don't hesitate to ask questions or seek out additional resources to help you make the best decision for your situation.

Enrolling in Medicare

Enrolling in Medicare can be a confusing process, especially for those who are new to the program or have never enrolled before. Understanding the eligibility requirements, when to enroll, and how to enroll are all important steps in making sure you have the coverage you need.

Eligibility for Medicare

To be eligible for Medicare, you must be a U.S. citizen or permanent resident who is 65 years or older, or you must meet certain disability requirements. If you are under 65 but have a disability or End-Stage Renal Disease (ESRD), you may also be eligible for Medicare.

If you are receiving Social Security benefits or Railroad Retirement Board benefits, you will automatically be enrolled in Medicare when you become eligible. If you are not receiving these benefits, you will need to actively enroll in Medicare.

When to Enroll in Medicare

There are certain times when you can enroll in Medicare, known as enrollment periods. It is important to enroll during these periods to avoid late enrollment penalties and to ensure that you have continuous coverage.

The initial enrollment period for Medicare is the seven-month period surrounding your 65th birthday. This includes the three months before, the month of, and the three months after your birthday. If you are already receiving Social Security benefits when you turn 65, you will be automatically enrolled in Medicare Part A and Part B. If you are not receiving Social Security benefits, you will need to actively enroll during this initial enrollment period.

If you miss your initial enrollment period, you can enroll during the general enrollment period, which runs from January 1 to March 31 of each year. Coverage will begin on July 1 of that year. There are also special enrollment periods for those who are losing employer or union coverage, or for those who have certain medical conditions or disabilities.

How to Enroll in Medicare

There are several ways to enroll in Medicare:

  • Online: You can enroll online through the Medicare website.
  • By phone: You can call the Medicare hotline at 1-800-MEDICARE (1-800-633-4227) to enroll over the phone.
  • In person: You can visit your local Social Security office to enroll in person.
  • By mail: You can complete a paper enrollment form and mail it to your local Social Security office. When enrolling in Medicare, you will need to choose between Original Medicare (Part A and Part B) and a Medicare Advantage plan (Part C). You will also need to decide whether or not you want to enroll in a Medicare Part D plan for prescription drug coverage. It is important to carefully consider your coverage options and to review your coverage annually during the annual enrollment period.

Coverage Under Original Medicare

If you're new to Medicare or considering enrolling, it's important to understand what coverage is included under Original Medicare. Let’s take a closer look at the Part A and Part B of this plan:

Part A (Hospital Insurance)

Part A covers inpatient hospital care, as well as some other medical services. This includes:

It's important to note that Part A only covers these services if they are medically necessary. If you choose to receive care in a facility that is not Medicare-approved, you may be responsible for paying some or all of the costs.

Part B (Medical Insurance)

Part B covers a wide range of medical services and supplies that are deemed medically necessary. This includes:

  • Doctor's visits
  • Outpatient care
  • Certain preventive services
  • Durable medical equipment (such as wheelchairs or oxygen tanks) It's worth noting that Part B does not cover all medical services. Some services, such as most prescription drugs, are not covered under Original Medicare. However, you can enroll in a separate Medicare Part D plan to get coverage for prescription drugs.

In addition to the services listed above, Original Medicare also covers certain diagnostic tests, surgeries, and other medical procedures. Some examples of covered services include:

  • X-rays and laboratory tests
  • Physical therapy and occupational therapy
  • Mental health care
  • Cancer treatment

Again, it's important to note that not all services are covered under Original Medicare. If you're considering a medical procedure or treatment, it's a good idea to check with Medicare to see if it is covered.

Costs Associated with Original Medicare

While Original Medicare does cover a wide range of medical services, it is not a free program. There are several costs associated with Original Medicare, including:

  • Deductibles: These are the costs you must pay before Medicare begins to cover your medical expenses. For example, you may have to pay a deductible before Medicare will cover your hospital stay.
  • Coinsurance: This is the percentage of the cost of a covered service that you must pay. For example, you may have to pay 20% of the cost of a surgery after you meet your deductible.
  • Premiums: These are the monthly fees you must pay to enroll in Original Medicare. The amount you pay will depend on your income and whether you are enrolled in Part A and/or Part B. In addition to these costs, you may also be responsible for paying for certain services that are not covered under Original Medicare. This is where supplemental insurance, such as Medigap, can be helpful in covering these additional costs.

Medicare Advantage Plans

Medicare Advantage plans, also known as Part C, are an alternative to Original Medicare that are offered by private insurance companies. These plans generally include all the benefits covered under Original Medicare, as well as additional benefits such as coverage for vision, hearing, and prescription drugs. If you're considering enrolling in a Medicare Advantage plan, it's important to understand the advantages and disadvantages, as well as the different types of plans available and how to enroll.

Advantages of Medicare Advantage Plans

One of the main advantages of Medicare Advantage plans is that they often offer more comprehensive coverage than Original Medicare. In addition to covering hospital stays, medical visits, and lab tests, many Medicare Advantage plans also include coverage for routine vision and hearing services, as well as prescription drugs. Some plans may also offer additional benefits such as dental and wellness programs.

Another advantage of Medicare Advantage plans is that they often have lower out-of-pocket costs compared to Original Medicare. Many plans have $0 premiums and offer copayments or coinsurance for certain services, which can make it easier to budget for your healthcare expenses.

Disadvantages of Medicare Advantage Plans

While there are many advantages to Medicare Advantage plans, it's important to also consider the potential drawbacks. One potential disadvantage is that you may have limited access to certain providers. Many Medicare Advantage plans use networks of providers, and you may need to see in-network providers to get coverage for your healthcare needs.

Another potential disadvantage is that you may have to pay more for certain services that are not covered under your Medicare Advantage plan. For example, if you need to see a specialist or have a procedure that is not covered under your plan, you may have to pay out-of-pocket for those services.

Types of Medicare Advantage Plans

There are several different types of Medicare Advantage plans available, each with its own set of benefits and limitations. Here are a few of the most common types of Medicare Advantage plans:

HMO (Health Maintenance Organization)

HMO plans typically require you to see in-network providers and may require you to get a referral from your primary care doctor to see a specialist. These plans often have lower premiums and out-of-pocket costs, but may have more limited coverage compared to other types of plans.

PPO (Preferred Provider Organization)

PPO plans typically allow you to see in-network or out-of-network providers, but you may pay more for out-of-network services. These plans often have higher premiums and out-of-pocket costs compared to HMO plans, but may offer more flexibility in terms of provider choice.

SNP (Special Needs Plan)

SNP plans are designed for people with specific health needs, such as chronic conditions or disabilities. These plans often offer additional benefits and services tailored to meet the needs of their enrollees.

PFFS (Private Fee-for-Service)

PFFS plans allow you to see any provider that accepts your plan's terms and conditions. These plans may have more flexibility in terms of provider choice, but may also have higher premiums and out-of-pocket costs compared to other types of plans.

How to Enroll in a Medicare Advantage Plan

If you're interested in enrolling in a Medicare Advantage plan, you'll need to first make sure you're eligible for Medicare. To be eligible for Medicare, you must be 65 or older, or have a qualifying disability or condition.

Once you're eligible for Medicare, you can enroll in a Medicare Advantage plan during your Initial Enrollment Period (IEP). Your IEP is a seven-month period that begins three months before the month you turn 65,includes the month you turn 65, and ends three months after the month you turn 65. If you're already enrolled in Medicare, you can switch to a Medicare Advantage plan during the Annual Enrollment Period (AEP), which runs from October 15 to December 7 each year.

To enroll in a Medicare Advantage plan, you'll need to choose a plan that meets your needs and budget, and then enroll through the insurance company offering the plan. You'll need to provide your Medicare information, as well as any additional information required by the insurance company. Once you're enrolled, you'll receive a Medicare Advantage plan card that you can use to access your benefits.

Costs Associated with Medicare Advantage Plans

Medicare Advantage plans generally have lower out-of-pocket costs compared to Original Medicare, but they may have higher premiums. The premiums for Medicare Advantage plans can vary depending on the plan and your location. In addition to premiums, you may also have copayments or coinsurance for certain services, such as hospital stays or medical visits.

Most Medicare Advantage plans offer $0 premiums, but it's important to consider all the costs associated with the plan, including copays, coinsurance, and deductibles, to make sure the plan fits your budget. It's also important to keep in mind that you'll still need to pay your Part B premium if you enroll in a Medicare Advantage plan.

Medicare Part D (Prescription Drug Coverage)

Medicare Part D can be a valuable addition to Original Medicare (Part A and Part B) that helps cover the cost of prescription drugs. It is important to understand the options available for prescription drug coverage and how to enroll in a Medicare Part D plan to ensure you have the coverage you need.

To be eligible, you must be enrolled in either Original Medicare or a Medicare Advantage plan that does not include prescription drug coverage. If you are already enrolled in a Medicare Advantage plan with prescription drug coverage, you do not need to enroll in a separate Medicare Part D plan.

There are several ways to enroll in a Medicare Part D plan. The easiest way is to enroll through the Medicare website. You can also enroll over the phone by calling 1-800-MEDICARE (1-800-633-4227). If you prefer to enroll in person, you can visit your local Social Security office or a Medicare help center.

The cost of a Medicare Part D plan will vary depending on the plan you choose and your location. Most plans have a monthly premium, which is an additional cost you pay to have the coverage. In addition to the premium, you may also have to pay a deductible, coinsurance, or copayments for your prescriptions. These costs will depend on the specific plan you choose and the medications you are prescribed.

It is important to carefully review the coverage offered by different Medicare Part D plans to find the one that best fits your needs. If you are having difficulty paying for your prescription drugs, you may be eligible for the Extra Help program, which provides assistance with the cost of Medicare Part D coverage. To find out if you qualify for Extra Help, you can visit the Medicare website or call 1-800-MEDICARE.

Supplemental Insurance (Medigap)

If you're on Medicare, you may have heard of Medigap insurance, also known as supplemental insurance. But what is Medigap insurance and how can it help you?

Medigap insurance is a type of insurance policy that is designed to supplement Original Medicare (Parts A and B). It helps to cover some of the costs that Original Medicare does not cover, such as copayments, coinsurance, and deductibles. Medigap insurance is sold by private insurance companies and is not affiliated with the government's Medicare program.

There are 10 standardized Medigap policies available, labeled A through N. Each policy covers a different set of benefits, such as skilled nursing facility coinsurance, foreign travel emergency coverage, and Medicare Part B excess charges. It's important to note that Medigap policies do not cover long-term care, vision or dental care, hearing aids, or private-duty nursing.

How Can Medigap Insurance Supplement Original Medicare Coverage?

Medigap insurance can help to reduce your out-of-pocket costs for medical expenses that Original Medicare does not cover. For example, if you have a Medigap policy that covers Part A deductibles, you will not have to pay the deductible for hospital stays out of pocket. Medigap policies can also cover copayments and coinsurance for medical services, such as doctor's visits or hospital stays.

Enrolling in Medigap Insurance

If you're interested in enrolling in Medigap insurance,[2] it's important to do so during your Medigap open enrollment period. This period begins on the first day of the month in which you turn 65 and are enrolled in Medicare Part B. During this time, insurance companies are required to sell you a Medigap policy at the standard rate, regardless of your health status.

After your open enrollment period ends, you may still be able to purchase a Medigap policy, but the insurance company may consider your health status and charge you a higher premium. It's also important to note that you can only have one Medigap policy at a time.

Staying Up to Date with Medicare

As a Medicare beneficiary, it's important to stay up to date with your coverage and make sure you have the right plan for your needs. This can be especially important during the annual enrollment period, when you have the opportunity to review and potentially change your coverage.

Annual Enrollment Period for Medicare

The annual enrollment period for Medicare[3] is a specific time each year when you can review and make changes to your Medicare coverage. This includes enrolling in or switching between Medicare Advantage plans, switching back to Original Medicare, and enrolling in or switching between Medicare Part D prescription drug plans.

The annual enrollment period for Medicare typically runs from October 15 to December 7 each year. During this time, you can make changes to your coverage that will go into effect on January 1 of the following year. It's important to note that outside of the annual enrollment period, you may only be able to make changes to your Medicare coverage under certain circumstances, such as moving to a new location or losing employer coverage.

Reviewing and Updating Coverage Options

During the annual enrollment period, it's important to review your current coverage and consider whether it still meets your needs. This might include considering factors such as your current health, any changes in your medications, and your budget.

If you're enrolled in Original Medicare (Part A and Part B), you might consider enrolling in a Medicare Advantage plan or adding a Medicare Part D prescription drug plan if you don't already have one. Medicare Advantage plans offer an alternative way to receive your Medicare benefits, and many plans include additional coverage such as vision, hearing, and dental. Medicare Part D plans offer prescription drug coverage to help lower the cost of your medications.

If you're already enrolled in a Medicare Advantage plan or a Medicare Part D plan, you might consider switching to a different plan if your current plan no longer meets your needs. It's also a good idea to compare the costs and coverage of different plans to see if there is a plan that might be a better fit for you.

Resources for Staying Informed about Medicare

There are a number of resources available to help you stay informed about Medicare and your coverage options. Here are a few to consider: Medicare.gov: This is the official website for Medicare, and it's a great resource for finding information about different types of coverage, enrolling in Medicare, and comparing plans. Your Medicare Handbook: You should have received a "Medicare & You" handbook when you first enrolled in Medicare. This handbook provides detailed information about your Medicare coverage and is a good resource to refer to throughout the year. State Health Insurance Assistance Program (SHIP): SHIP is a free program that provides one-on-one counseling and assistance to Medicare beneficiaries. SHIP counselors can help you understand your coverage options and assist you with enrolling in a plan. Social Security Office: You can visit your local Social Security office or call the Social Security Administration to get information about your Medicare coverage and make changes to your enrollment.
