Not sure if it is the same with NCA, but I'm on contract with PARC and with BUPA insurance, it does NOT cover my family in the US, they would only be covered if I change my domicile outside of the US. This is one issue where PARC is very substandard for guys living in the US, they offered supplemental insurance for my family but what they quoted me was higher than what I was paying. Make sure they clarify this issue with you because I'm afraid you will have to get supplemental insurance on your own.
