What are the various components of Medicare?

Understanding Medicare: A Comprehensive Guide to Parts A, B, C, and D

 

Medicare, the federal health insurance program primarily for people aged 65 or older, and certain younger people with disabilities, can seem complex with its various "parts."1 However, understanding these components is crucial for making informed decisions about your healthcare coverage. Let's break down Medicare into its four main parts: Part A, Part B, Part C, and Part D.

​

Choosing Your Medicare Path

 

When you become eligible for Medicare, you generally have two main ways to get your coverage:

​

1. Original Medicare (Part A & Part B) + Optional Add-ons: You can choose Original Medicare and then decide to add a separate Part D plan for prescription drug coverage. You can also purchase a Medicare Supplement Insurance (Medigap) policy to help cover out-of-pocket costs like deductibles and coinsurance associated with Original Medicare.

2. Medicare Advantage Plan (Part C): This option bundles your Part A and Part B benefits, and often Part D, into a single plan offered by a private company.

​

Understanding the distinct roles of Medicare Parts A, B, C, and D is the first step toward navigating your healthcare options and selecting the coverage that best fits your individual needs and budget. It's highly recommended to review your options annually during the Medicare Open Enrollment Period to ensure your plan continues to meet your healthcare requirements.

Original Medicare: Parts A and B

 

Original Medicare is the traditional fee-for-service program provided directly by the federal government.2 It consists of two main parts:

 

 

Medicare Part A (Hospital Insurance)

 

Part A primarily covers inpatient care in hospitals, skilled nursing facilities, hospice care, and some home health care. Think of it as your "hospital insurance."

 

What it Covers :​​​​​

​

• Some home health care: If you're homebound and require skilled care.

• Hospice care: For individuals with a terminal illness.

• Skilled nursing facility (SNF) care: Covers skilled nursing and rehabilitation services after a qualifying hospital stay.

• Inpatient hospital stays: This includes semi-private rooms, meals, nursing services, and medical supplies and equipment used during your stay.

• Costs: Most people do not pay a monthly premium for Part A if they or their spouse paid Medicare taxes through employment for a sufficient period (usually 10 years or 40 quarters). However, there are deductibles and coinsurance costs for services.

   

 

Medicare Part B (Medical Insurance)

 

Part B is your "medical insurance" and covers services from doctors and other healthcare providers, outpatient care, medical supplies, and preventive services.

 

What it Covers :​​​​

​

• Some prescription drugs: Primarily those administered in a doctor's office or outpatient setting (e.g., chemotherapy).

   

• Many preventive services: Such as flu shots, various screenings (e.g., for cancer, diabetes), and yearly "Wellness" visits.

   

• Durable medical equipment (DME): Like wheelchairs, walkers, and oxygen equipment.

   

• Outpatient care: Such as services received in a hospital outpatient department or clinic, lab tests, and X-rays.

   

• Doctor's services: Including office visits, consultations, and surgeries.

   

• Costs: Most individuals pay a monthly premium for Part B, which can be deducted from Social Security benefits. There's also an annual deductible, and after that, you typically pay 20% of the Medicare-approved amount for most services (coinsurance).

   

 

Beyond Original Medicare: Parts C and D

 

While Original Medicare provides essential coverage, it doesn't cover everything. This is where Part C and Part D come into play, offering additional options for comprehensive coverage.

 

 

Medicare Part C (Medicare Advantage)

 

Medicare Part C, also known as Medicare Advantage (MA) Plans, are an alternative way to receive your Medicare Part A and Part B benefits. These plans are offered by private insurance companies approved by Medicare.

 

What it Covers:

​

• All Part A and Part B benefits: Medicare Advantage plans are required to cover at least everything that Original Medicare covers, with the exception of hospice care (which remains covered by Original Medicare) and clinical trials.

• Often includes prescription drug coverage (Part D): Many Medicare Advantage plans are "bundled" plans that include prescription drug coverage, eliminating the need for a separate Part D plan.

   

• Extra benefits: A significant draw of Medicare Advantage plans is the potential for additional benefits not covered by Original Medicare, such as routine dental, vision, and hearing care, as well as fitness programs and wellness initiatives.

   

• Costs & Structure:

  • You must continue to pay your Medicare Part B premium.

  • Medicare Advantage plans may have their own monthly premiums (some are $0), deductibles, copayments, and coinsurance.

     

  • They often have a yearly limit on your out-of-pocket costs for Part A and Part B services, providing a cap on your spending.

  • Many MA plans operate within a network of doctors and hospitals, meaning you may pay more if you go out-of-network. Common types include Health Maintenance Organizations (HMOs) and Preferred Provider Organizations (PPOs).

     

 

Medicare Part D (Prescription Drug Coverage)

 

Medicare Part D is standalone prescription drug coverage offered by private insurance companies approved by Medicare. It helps cover the cost of prescription medications.

 

What it Covers:

​

• Prescription drugs: Plans cover a list of prescription drugs (formulary), which can vary by plan. Both brand-name and generic drugs are typically included.

   

• Costs & Structure:

  • You typically pay a monthly premium for your Part D plan.

  • There may be an annual deductible before coverage begins.

  • You'll pay copayments or coinsurance for your prescriptions, which can vary based on the drug's tier (generic, preferred brand, non-preferred brand, specialty).

  • It's crucial to compare plans to ensure your medications are covered and to understand the associated costs.

  • A late enrollment penalty may apply if you don't sign up for Part D when first eligible and don't have other creditable prescription drug coverage.
