Yeah blue cross is pretty popular here but hospital treatment is so damned cheap that you will normally always pay far more being over insured..
Far better to put the money in a high interest earning acc or government/blue chip bond etc which is exclusively for future med expenses..Another tip is always have 500,000K in an HSBC acc for fast withdrawals if needed.. If the treatment is not an emergency and looks like it`ll be ridiculously expensive then jump on a plane and make better use of your past NHS contributions..
IMO lang.
(of course,get Phil health coverage too as its just to cheap and good value NOT to have)
