If you have moved outside the United States permanently, you should decide whether to keep Medicare Parts A and B. While you can have Medicare while living abroad, it will usually not cover the care you receive. Most people qualify for premium-free Part A, meaning you will pay nothing for coverage. However, keeping Part B may not be worth the cost if you live abroad permanently and do not take frequent trips to the U.S. Medicare does not provide any coverage for medical or hospital services outside the U.S. Therefore, expats in Argentina may need to explore other health coverage options in the country.
