What Are Medigap Policies? 
That is an excellent question ! There is a `` gap '' between what your Medicare coverage pays for , and what the provider charges for the treatment . That difference , along with your co-pays and deductibles are what you have to come up with . For many folks , that amount is too much . So insurers offer Medigap plans , or supplemental insurance plans , to help fill in that `` gap '' . The good part is that the plans provide a stable , easily accepted way to help cut your costs ; the bad part is that there are many to choose from , and it can be very difficult to find the one that will work best for you . It is important that you work with your health care professional to get what is best for you . Thanks for asking !
