If you need medical care, you will never be refused by the NHS.
If you have medical insurance, bring you card with you, it will help identify you and if you have any medical needs we may be able to use the ID to find out what previous records you have should that be important.
Plus if you have insurance, there is no trouble with bills.
NHS is now asking foreign visitors for contributions.
If you have insurance, its easier.... its paid, no hassles.
If not, you may get a bill.
However, that will be after.... after you have recieved treatment.....
NHS will NEVER refuse to treat you.**
Its party of our "Constitution", Health care is for all, regardless of ability to pay.
**Unless that is you prove untreatable... NHS will now refuse to treat those who are threatening or aggressive from intoxication or just bad manners... just making that point in case anyone else is reading expecting something different....
