Do I lose Medicare if I live abroad?

Remember, you can have Medicare while you live abroad, but it will usually not cover the care you receive. Most people qualify for premium-free Part A, meaning you will pay nothing for coverage. If you must pay a premium for Part A, be aware of the high monthly cost for maintaining Part A coverage.
