I do not think it is more expensive than the USA but keep in mind the following:
OSDE 450 is essentially a "Cadillac" plan; there are no extra costs other than the monthly payment, the most doctors accept the plan, and if you need to be hospitalized you get a private room at all the best private hospitals. Plastic surgery is included in the plan once every two years, teeth whitening is included once every two years, and it comes with very useful travel insurance at no additional cost.
