How is it different from Original Medicare?

Moving from pros and cons leads us to understand how Medicare Advantage differs from Original Medicare. Medicare Advantage offers extra benefits that Original Medicare does not. It often includes coverage for things like vision, dental care, and wellness programs. Many plans also cover prescription drugs.

Original Medicare has different parts: Part A covers hospital stays, while Part B covers doctor visits and outpatient services. In contrast, most Medicare Advantage plans combine these parts into one plan. About 80 percent of these plans require prior authorization for certain medical services. This helps ensure that healthcare services are necessary before approval is granted.

What is Medigap, and How Does it Work with Medicare and Medicare Advantage?

Medigap helps cover costs that Medicare may not pay. It works with both Original Medicare and some Medicare Advantage plans to fill in the gaps for seniors.

Medigap coverage

Medigap helps cover costs not paid by Original Medicare. This includes things like co-payments, coinsurance, and deductibles. We can think of Medigap as extra insurance that works alongside Medicare. It offers peace of mind for medical expenses.

Costs for Medigap plans vary based on where we live and what plan we choose. Coverage options include several plans labeled A through N, each with different benefits.

Choosing between Medigap and Medicare Advantage is important because they serve different needs. We should consider our health care services and costs carefully to make the best choice for us.

Costs

Costs can vary when it comes to Medicare Advantage plans. Many of these plans require prior authorization for certain medical services. This measure helps ensure that the care we receive is necessary and appropriate.

About 80 percent of Medicare Advantage plans ask for this preapproval before we get health services. This process helps in managing healthcare costs, but it might delay access to needed treatment. In 2025, insurers made nearly 50 million prior authorization requests related to medical necessity.

While some see prior authorization as a cost-saving tool, others worry about potential delays in patient care and increased paperwork for doctors. It is essential to understand both sides as we choose our options moving forward.

Benefits

Prior authorization can offer benefits for us as we navigate our Medicare Advantage plans. This process helps ensure that the healthcare services we receive are medically necessary. By requiring preapproval, insurers aim to keep costs manageable and help us get the right Medicare.

About 80 percent of Medicare Advantage plans require this approval before certain services. In 2025, these insurers made nearly 50 million prior authorization requests to confirm medical necessity.

Each step is meant to protect our health while reducing unnecessary expenses in our care journey. Next, let's explore how prior authorization works in more detail.
