Yesterday when in the office of Servi Med in Cabarete, I saw a sign saying they now accept Blue Cross Blue Shield and International Health Insurance. To set it up, they need your passport and insurance card number. Takes about 3 days to get approval from the insurance company, according to the sign. So if you wait to set it up until you next consult the doctor, they will want your credit card number in case it is not approved for some reason or other.
