The same thing happened with my brother too. But on consulting the experts who helped and guided us on clearing the basic of each and every plan made us realise that we were expecting more on just a basic plan. Then after, as suggested by our doctor and insurers too, we ought to buy Medigap plan G insurance and got all the facilities which we were looking for. If you want you can also contact the same team through this website and can get the details of all the Medicare insurance plan.
