I have been offered Medicare , A is free but you pay for B. I have very good insurance and it pays all but token amount for Medicine and Doctor visits. I want to carry it till current reconstruction is finished but I am facing the problem of my husband retireing and needing my own insurance. Will there be a big difference in types of treatment that the medicare will pay for and regular insurance will pay for. I know I need a suplimental policy. Will this all cover like my old insurance did. What are the problems?
