The 4 Parts of Medicare


Medicare is a government-run healthcare program that offers coverage to individuals who meet certain criteria. It is available to those who are 65 years and older, as well as individuals under 65 who receive Social Security Disability Insurance (SSDI) or have End-Stage Renal Disease (ESRD). The Centers for Medicare & Medicaid Services (CMS) is the federal agency responsible for managing the Medicare program. It is important to note that Medicare is not provided free of charge. The program is funded, in part, by the social security and Medicare taxes that individuals have contributed over the years. 

Medicare Part A

@ Glance


Medicare Part A is an important component of the Medicare program, providing coverage for hospitalization and inpatient care. It is often referred to as "hospital insurance."

Here's an overview of Medicare Part A:

  • Coverage: Part A covers various hospital services, including inpatient stays, skilled nursing facility care, hospice care, and some home health services. This includes room and board, necessary supplies, medications, and other medically necessary services received during a hospital stay.
  • Hospital stays: Part A provides coverage for hospital stays, including semi-private rooms, meals, general nursing care, and necessary hospital services and supplies.
  • Skilled nursing facility care: Part A covers skilled nursing facility care following a hospital stay of at least three consecutive days, for up to 100 days. This includes skilled nursing care, rehabilitation services, and other medically necessary services.
  • Hospice care: Part A provides coverage for hospice care for individuals with a terminal illness, including pain management, counseling, and support services.
  • Home health services: Part A covers some medically necessary home health services, such as skilled nursing care, therapy services, and home health aide services, if you meet certain criteria.

While Part A provides coverage for many hospital-related services, it's important to note that it does not cover all costs. You may still have out-of-pocket expenses, such as deductibles, coinsurance, and copayments. Understanding the specific coverage and associated costs under Medicare Part A is crucial, and it's recommended to consult Medicare resources or healthcare providers for more detailed information.

Medicare Part B

@ Glance

Medicare Part B provides coverage for ambulatory medical services and preventive services. It is often referred to as "medical insurance."

Here's an overview of Medicare Part B:

  • Coverage: Part B covers a wide range of medical services necessary for diagnosing and treating medical conditions. This includes doctor visits, emergency care, laboratory tests, medical equipment or devices, and other medically necessary services.
  • Preventive services: Part B includes coverage for preventive care aimed at preventing illness or detecting health conditions at an early stage. This can include vaccinations, cancer screenings, routine physical examinations, and more.
  • Additional coverage: Part B also covers ambulance services, outpatient mental health services, durable medical equipment (DME), and prescription drugs administered in medical settings.
  • Cost-sharing: While Part B provides coverage, it's important to note that it does not cover all costs. There is an annual deductible, which is $266 in 2023, and after meeting the deductible, there is a 20% coinsurance for most services.

It's essential to understand that Part B coverage has certain out-of-pocket costs that you are responsible for. These costs include the annual deductible and the coinsurance. Consulting Medicare resources or healthcare providers can provide more specific information on what is covered and the associated costs under Medicare Part B..

Medicare Part C

@ Glance

Medicare Part C, also known as Medicare Advantage plans, offers an alternative to Original Medicare. These plans are administered by private insurance companies that work in partnership with the federal government.

Here are the key points to understand about Medicare Part C and Medicare Advantage plans:

  • Coverage: Medicare Advantage plans are required by law to cover all the services provided under Medicare Parts A and B. This includes hospitalization, medical services, and outpatient care. Some Medicare Advantage plans may also offer coverage for prescription drugs, going beyond what Original Medicare provides.
  • Additional services: Part C plans often offer extra benefits that are not covered by Original Medicare. These may include dental, vision, and hearing services, as well as over-the-counter benefits and access to fitness memberships.
  • Premiums and cost-sharing: Medicare Advantage plans typically have low or even $0 monthly premiums, making them an affordable option for beneficiaries. However, it's important to note that these plans may have copayments, deductibles, and coinsurance for different services. For instance, you might have a $0 copayment for primary care visits, but a $50 copayment for specialist visits.
  • Maximum-Out-Of-Pocket (MOOP): All Medicare Advantage plans have a MOOP, which is the maximum amount you would have to pay out-of-pocket for covered services in a given year. This protects you from excessive medical expenses and sets a cap on your healthcare costs.

It's essential to carefully review and compare Medicare Advantage plans to understand their specific coverage, costs, and network of healthcare providers. You can refer to plan documents or consult with insurance agents or brokers for more detailed information.

Medicare Part D

@ Glance

Medicare Part D is dedicated to providing prescription drug coverage to Medicare beneficiaries. Here are some important points to know about Part D:

  • Coverage through private insurance companies: Part D Prescription Drug Plans (PDPs) are approved by CMS (Centers for Medicare & Medicaid Services) but are offered by private insurance companies. These plans are designed to help cover the costs of prescription medications.
  • Standalone and integrated options: Beneficiaries have the choice to enroll in a standalone Prescription Drug Plan (PDP) if they have Original Medicare (Parts A and B). Alternatively, they can opt for a Medicare Advantage Plan (Part C) that includes Part D coverage. However, to join a Medicare Advantage plan with prescription drug coverage (MAPD), enrollment in both Parts A and B is necessary.
  • Formularies and drug coverage: Each insurance company that offers Part D plans provides a formulary, which is a list of approved prescription drugs covered under their plans. It's crucial to review the formulary to ensure that the medications you need are included in the coverage.
  • Out-of-pocket costs: Part D plans have different tiers or cost-sharing structures for prescription medications. This means that you may have varying copayments or coinsurance amounts for different drugs. It's important to pay attention to your out-of-pocket expenses and understand how much you would need to contribute for your prescriptions.

When considering a Part D plan, it's recommended to compare different options, review the formularies, and consider your specific medication needs. This will help you choose a plan that provides the coverage you require at a reasonable cost.
