I cannot possibly cover Medicare completely if I blogged for a year about it. I will throw out some suggestions for you that I think can help you and your parents with it.
Make sure your parents sign up for online access to their Medicare info This lets them see when claims are processed and you can see any issues (and try to thwart them) before you would get information by mail. It is preferable to see if your parents will let you have access as well.
When your parents get ready to sign up for Part D (Prescription), have them go to medicare.gov to price polices. They can put in the prescriptions they use and where they get their medicines and this tool will present you with the best options (considering cost and location) for their Part D policy
Have your parents speak with Medicare and allow you access via phone to be able to discuss Medicare issues with Medicare representatives if need be. All they have to do is call the Medicare toll free number and answer a few questions to do this. It can be very helpful to have the ability to do this especially if they are ill or simply cannot understand the complexities of Medicare. You will need their Medicare number - they should have a card with this info on it.
Finally, I’ll throw out some specific situations we had issues with in case these might be helpfulHopefully this will be of some help to you.
