All Medicare Advantage plans must offer the same benefits as Original Medicare, but are allowed to have different costs and restrictions. Certain Medicare Advantage plans offer additional limited benefits, such as vision or dental coverage.
The two most common types of Medicare Advantage plans are health maintenance organizations (HMOs) and preferred provider organizations (PPOs). HMOs generally only cover care from providers who are within their networks. If you go out-of-network, you will usually be responsible for the full cost of your care. They also often require referrals to see specialists. On the other hand, you will pay the least if you see a provider within a PPO’s network, but it provides limited coverage for out-of-network providers. Additionally, PPOs do not require referrals to see specialists. Due to this additional freedom, the premiums for a PPO are generally higher than that of an HMO.
