Medicare Advantage plans are key to maintaining and utilizing the Medicare program. They not only provide additional coverage that is essential for most retirees, but they also protect you from paying too much for required treatments that will help keep you in good shape. This maximum limit you can pay covers all of the costs that you might incur through Part A or B plans. In Alaska there is no consistent formal limit because plans are considered on a case by case basis. Although you are offered flexibility with the plans as many insurance companies allow you to go to multiple doctors and treatment centers. With healthcare reform, the new laws are not set in stone for the state of Alaska as the system is unique in comparison to every other state.
