You need to check the coverage included in your medicare supplement plan or MediGap policy. Although some medicare supplement plans do offer foreign medical, they are generally not as comprehensive as a travel medial plan that would include emergency evacuation, repatriation, trip interruption, etc. Most Medigap plans that cover foreign travel require the patient pay a $250 deductible plus 20 percent coinsurance. There is also a lifetime benefit maximum of $50,000.
