Both Medicare Advantage and Medigap are supplemental options to your Original Medicare plan. Medicare Advantage plans work similar to an individual or employer HMO or PPO plan, helping lower out-of-pocket costs with predictable copayments, smaller deductibles and out-of-pocket costs. You can also save money with a Medicare Advantage plan by seeing a doctor within the plan’s network.
On the other hand, Medigap plans work with your Original Medicare to help pay for most or all of your out-of-pocket costs that Original Medicare doesn’t cover, like copayments, coinsurance and deductibles. Medigap plans also give you more flexibility when it comes to doctor choice, because you can go to anyone who accepts Medicare.
