Deciding between Medicare Advantage and Original Medicare can be a challenging decision for seniors, as both options have their advantages and drawbacks. At DeSeguros, we specialize in senior benefits and understand the complexities of navigating Medicare plans. As independent health insurance agents, we work with top insurance providers like Aetna, Anthem, Cigna, Humana, Kaiser Permanent, and UnitedHealthCare to ensure that our clients have access to the best resources and guidance for their specific healthcare needs.

This article aims to provide a comprehensive comparison of Medicare Advantage and Original Medicare, exploring the key features, benefits, and potential downsides of each plan type. By understanding the fundamentals of these two options and assessing their unique healthcare needs, seniors can make informed decisions and choose the coverage that best suits their circumstances.

Original Medicare (Part A and Part B) is a fee-for-service program managed by the federal government that covers hospital insurance (Part A) and medical insurance (Part B). On the other hand, Medicare Advantage (Part C) is an alternative to Original Medicare offered by private insurance companies approved by Medicare, which bundles Part A, Part B, and often prescription drug coverage (Part D) into a single plan alongside additional benefits not typically covered by Original Medicare.

Let’s dive deeper into the differences between these two types of Medicare plans, examining the areas of coverage, costs, provider networks, and enrollment to provide the insights seniors need to make confident and informed decisions about their healthcare coverage. With the right knowledge and support, seniors can make the best choices for their well-being and enjoy peace of mind throughout their golden years.

Coverage: What’s Included in Medicare Advantage and Original Medicare Plans?

When comparing Medicare Advantage and Original Medicare, one of the key areas to consider is the scope of coverage each plan offers. Here is an overview of what each plan type typically covers:

  1. Original Medicare (Part A and Part B): Original Medicare provides essential hospital and medical insurance coverage. Part A covers services such as hospital stays, skilled nursing facility care, hospice care, and some home health services. Part B covers doctor’s visits, outpatient care, preventive services, home health services, and some medical equipment.
  2. Medicare Advantage (Part C): Medicare Advantage plans must cover everything included in Original Medicare, but these private plans often extend their coverage to include additional benefits such as prescription drug coverage (Part D), vision care, dental care, hearing services, and wellness programs.

Costs: Comparing the Expenses Associated with Medicare Advantage and Original Medicare

Another essential factor to consider when choosing between Medicare Advantage and Original Medicare is the cost structure associated with each plan type. Here’s a breakdown of the costs you may encounter with each option:

  1. Original Medicare: With Original Medicare, beneficiaries are typically responsible for premiums, deductibles, and coinsurance, with no out-of-pocket limit. Part A premium is typically not required for those who paid Medicare taxes while working. Part B premium is based on your income, with higher earners paying more. Coinsurance for Part B is typically 20% of the Medicare-approved amount for most doctor services, outpatient therapy, and durable medical equipment.
  2. Medicare Advantage: Medicare Advantage plans often have lower out-of-pocket costs than Original Medicare, with some plans even offering $0 premiums. However, these plans may require copayments for certain services and may have more restricted provider networks. Beneficiaries must continue to pay their Medicare Part B premium in addition to any premiums, deductibles, copayments, or coinsurance associated with their Medicare Advantage plan. Most plans have an annual out-of-pocket limit, providing financial protection for seniors with high healthcare costs.

Provider Networks: Comparing Access to Healthcare Providers and Services

The choice between Medicare Advantage and Original Medicare also hinges on the breadth and quality of provider networks available under each plan type. Consider the following aspects when comparing your options:

  1. Original Medicare: With Original Medicare, beneficiaries can see any healthcare provider that participates in Medicare, offering a higher level of flexibility when choosing healthcare services. Importantly, Original Medicare generally does not require referrals to see specialists, providing an additional layer of convenience for seniors with complex healthcare needs.
  2. Medicare Advantage: These plans often have more limited provider networks, and beneficiaries may need to rely on in-network doctors and hospitals to receive coverage, which can be more restrictive compared to Original Medicare. However, some Medicare Advantage plans, such as Preferred Provider Organizations (PPOs) and Private Fee-for-Service (PFFS) plans, offer more extensive provider networks and greater flexibility, though potentially at a higher cost.

Enrollment: Understanding the Window of Opportunity

Enrollment timelines and processes are crucial differentiators between Medicare Advantage and Original Medicare, and understanding them can help you plan your healthcare coverage effectively.

  1. Original Medicare: Enrollment in Original Medicare is automatic for most seniors when they turn 65, provided they’re already receiving Social Security benefits. For those not automatically enrolled, the Initial Enrollment Period spans seven months, including three months before their 65th birthday, their birth month, and three months following their birthday.
  2. Medicare Advantage: To enroll in a Medicare Advantage plan, seniors must first be enrolled in Medicare Parts A and B. Enrollment in a Medicare Advantage plan typically occurs during the Annual Election Period, which runs from October 15 to December 7 each year. Beneficiaries can also switch or drop their Medicare Advantage coverage during the Medicare Advantage Open Enrollment Period from January 1 to March 31.


Choosing between Medicare Advantage and Original Medicare can be a challenging task, but armed with the right information and guidance, seniors can make informed decisions that align with their unique healthcare needs. By considering the aspects of coverage, costs, provider networks, and enrollment timelines, seniors can identify the best Medicare plan for their situation.
