In France, there is a minimum contribution to your healthcare which is paid by the social security system and then the rest is for you to pay for. The vast majority of people have health insurance which reimburses all or part of the difference. If you are employed then your employer has to provide mandatory healthy insurance as part of your salary and benefits package. Mine costs about 50€ per month. If you are on an extremely low income then you can access government funded health insurance free of charge to cover this part.
So, for example, I go to the GP. The appointment costs 25€. I pay by card. The doctor also takes my social security card and records how much I have paid and what the appointment was for.
A few days later, social security reimburses me 17.50€ and my health insurance reimburses me 7.50€.
Healthcare professionals are classed as either Sector 1 or Sector 2. Sector 1 professionals have to charge the fees set by social security, which are entirely reimbursed by social security. So if you see a Sector 1 professional, you get everything reimbursed even if you don't have health insurance. Sector 2 professionals can charge what they like, but I think the trade off is that they pay much higher taxes. (Healthcare professionals are generally self employed.)
So if I see a Sector 2 specialist, say a gynaecologist for a pelvic ultrasound, the appointment might cost me 70€, I get 23€ reimbursed by social security, and my health insurance might reimburse me anything from 23€ (meaning I end up paying 24€ in total) or it might pay the whole amount. It depends how good your health insurance policy is.
If you have something like cancer, everything is covered and you just have to fill in the paperwork and it's all taken care of.
I found it very difficult to get my head round the system at first, there are a lot of pitfalls and it's very very complicated to understand. I'm sure there are many people who don't get everything they are entitled to because they can't figure out the paperwork.
But on the other hand, I can't deny that the healthcare I've had since moving here has been absolutely world class.
After suffering recurrent miscarriages and finally deciding during the pandemic that enough was enough, I was able to shop around for the best gynaecologist, get an appointment within a matter of days, and get treated quickly.
There's a fantastic app for booking appointments where if you choose the doctor you want and book literally any appointment, you can activate an alert feature and you'll get a message as soon as someone cancels an earlier appointment. I've been able to get seen really quickly this way.
I also had two sick children right before Christmas, the night before we were due to drive to the UK for the holidays. At 2am, when one of them had vomited several times and the other had just woken up with a fever, I managed to get a double appointment with the out of hours doctor at 5:45 am, a 15 minute drive away. By 6:15 am we were back home with two prescriptions for antibiotics.
I was very dubious at first but I can't deny that it is a better system.
And don't even get me started on how superior the maternity care is.
