Am finding that cover is full of holes like Swiss cheese.
Specific diseases are not covered.
There is a 1 year moratorium on some conditions before cover commences. So you have to pay for your first year and these items are not covered.
Last December I had an accident where a car ran over me. The driver's insurance company representative came to Bumrungrad Hospital and told me the driver's insurance covered me. Now, months later, comes a bill from Bumrungrad, whose cashier originally accepted the insurance.
