For those of you who are new to France, and I have written about this before, you need to be careful and go in with your eyes open.
Do not make assumptions and talk to several people who work in the healthcare system here and who have experience of the UK systems. Most importantly, do not assume that there is a 100% reciprocal arrangement with the UK and be sure to sort out the forms BEFORE you arrive. Many expats have told me that the healthcare system in France is better than the UK. Sadly, I don't agree. Here, we have, essentially, a PRIVATE healthcare system in so far as individuals pay for it, not the tax payer.
Why does this make a difference? Healthcare here is more akin to the American system is so far as a) you pay for everything you use including ambulances and bandages, and b) the private system makes doctors and specialists like loan sharks.
Why is this bad? Private healthcare professionals need to make money not just a living. So if you present with a simple cold after 7 days, you will most often be asked to take an xray (200 euros) plus be given antibiotics. Now, I have work in the pharmaceutical industry, but even a half educated person knows that you should not take antibiotics for a common cold. If it turns to pneumonia which is rare except in older people (55+ year olds), then that's something else. The more educated healthcare professionals know this too, but like I said, they want to make money.
Secondly, private healthcare systems usually have serious gaps especially outside major connurbations. Unlike an NHS hospital which must cater to the general populace, a private healthcare system (like a private transport system) is designed to maximise reveunue, not cater to the periphery of the population.
Indeed, a 'free' healthcare system - where healthcare professionals are not responsible for any form of financial burden - should, theoretically, be more likely to proliferate bad practice and useless (read: money-spinning) patient testing. However, in my experience, in the UK, testing is on a 'need' only based on specific indications or patient circumstances. Punters are not referred because they're a potential source of income.
Lastly, the gaps in the reciprocal arrangement between the NHS and the French system will be noticed far more by the 55+ year olds especially if you haven't paid into the system before you arrive, e.g. if you come here to retire. If you do this, you need to factor in the cost of say, cancer medication which will be substantial if the type of cancer you have is terminal and/or regular trips back to the UK.
Examples:
1. Cost of medication. You will find that something as simple as paracetomol is only available through pharmacies who charge 5 times more expensive than Boots and around 10 times more than a drug store in Australia.
2. A friend of mine went to a dermatologist with a simple (topical) skin complaint. She came out 200 euros lighter from the pharmacy and also had to pay 80 euros for the consultation. Even a complicated skin complaint wouldn't cost the NHS anywhere near this much on a first visit.....
