I would strongly recommend getting International Medical Travel Insurance. If you know someone who is about to travel abroad do ask them if they have purchased inexpensive medical coverage while abroad? There are plenty of news stories of travellers  getting hospitalized abroad with medical bills reaching several hundred thousand dollars; in some cases your passport would be taken from you to ensure payment while in that country. When you return to the US you will be able to submit your medical reciepts to Medicare Supplement coverage you may have for additional reimbursement. Call me directly if you have any questions or just need an ear to clarify your future plans. I will be happy to help you.
