I broke my wrist several years ago and was taken to Centro Medico Bournigal - a private hospital - in Puerto Plata. My insurance company was billed (and they paid in full) over $11,000 US for two overnight stays because the doctor set the wrist twice - and THEN I ended up going to the US for surgery on it.
Ah!!!!!, you have a foreign insurance policy, of course, they are going to charge your insurance what your insurance would had paid in the STATES.
My mother fell in January and we took her to "El centro medico Cibao" (She has insurance in the DR) she had stitches we didn't pay a penny.
My big brother drunk too much in December, i think he got intoxicated he was taken to HOMS in Santiago, stayed there for two days, we just paid around 30,000 Dominican pesos, so i guess they charge "Gringos" (foreigners) more just for being foreigner (gringos).
