What Is Medicare Part C? Understanding Medicare Advantage Plans

When it comes to Medicare, there’s more than just Parts A and B. Many people are surprised to learn about Medicare Part C, also known as Medicare Advantage. If you're exploring your Medicare options, understanding Part C can help you make the best decision for your health and lifestyle.
At Temecula Medical Group, we're here to help you cut through the confusion and get the care you need—starting with the basics of Medicare Part C.
What Is Medicare Part C (Medicare Advantage)?
Medicare Part C, or Medicare Advantage, is an all-in-one alternative to Original Medicare (Parts A and B). These plans are offered by private insurance companies approved by Medicare.
When you enroll in a Medicare Advantage plan, it replaces your Original Medicare coverage but still gives you access to the same benefits—with some added extras.

Important Things to Know
➤ Provider Networks
Most Medicare Advantage plans have networks—meaning you may need to see doctors and use facilities within that network to get full coverage.
➤ Costs
Medicare Advantage plans often have low or $0 premiums, but you may have copays or coinsurance when you use services. Out-of-pocket limits help protect you from very high costs.
➤ Plan Variety
Plans can vary greatly depending on where you live. Coverage, premiums, and networks differ by county and provider.
