The National Health Service (NHS) is the name commonly used to refer to the five single-payer publicly funded healthcare systems in the United Kingdom and the Isle of Man , collectively or individually, although only the health service in England uses the name 'National Health Service' without further qualification. The publicly-funded healthcare organisation in Northern Ireland does not use the term 'National Health Service', though it is still sometimes referred to as the 'NHS' as well.[1] Each system operates independently, and is politically accountable to the relevant devolved government of Scotland (Scottish Government), Wales (Welsh Assembly Government) and Northern Ireland (Northern Ireland Executive), and to the UK government for England. The United Kingdom has a reciprocal agreement with the Isle of Man National Health Service which will be reviewed by September 2010.
There is generally[2] no discrimination when a patient resident in one country of the United Kingdom requires treatment in another. The consequent financial matters and paperwork of such inter-working are dealt with between the organisations involved and there is generally no personal involvement by the patient comparable to that which might occur when a resident of one European Union member country receives treatment in another.
