Erm, if the OP is living in another country then
a) there are lots of examples where you are still perfectly entitled to NHS care (for example based on where you pay tax or who you actually work for).
b) I would assume that she has health insurance which may be international, and in which case she would be entitled to care in the UK because her insurance company would foot the bill.
I am tired of reading the xenophobic bigoted comments on MN that AUTOMATICALLY assume that the ex-pat OP is being a health tourist complete with nasty comment about morality. Its jumping to conclusions massively.
The OP has made NO comment to suggest that she would not be eligible or has no intention to pay.
It really says a lot more about the poster making the post than the OP. Its unhelpful and generally doesn't inform the OP. Its just judgmental nonsense.
In actual fact, it even says on Holiday's link:
You can receive free NHS hospital treatment if you:-
normally work in the UK, but are temporarily working abroad for less than five years. You also need to have lived in the UK continuously for at least ten years before going overseas.
It is NOT straightforward by any means. We don't know the exact circumstances of the OP or her intension.
Its wrong to make these rather horrible comments without asking questions and finding out those details.
