Why it matters
Once you’re registered with French social security, you’re expected to nominate a “médecin traitant,” the equivalent of a GP in the UK.
It sounds like a formality. It isn’t.
Skip this step and every consultation with a specialist gets reimbursed at a much lower rate — typically 30% instead of 70%.
Most newcomers find out about it either from a pharmacist, a GP – or the sting of a smaller-than-expected reimbursement.
How the system works
Everyone aged 16 or over is expected to have a named médecin traitant, who acts as the first point of contact for anything health-related. This doctor gets to know your history, coordinates your care and keeps your medical record up to date.
Stay within this structure (officially called the parcours de soins coordonné) and you’re reimbursed at the standard rate.
If you miss out the declaration, or see a doctor who isn’t your named médecin traitant without a referral, Assurance Maladie will still reimburse you. It just reimburses you a lot less. On an ordinary GP consultation the difference is a few euros. However, on a run of specialist appointments, it can really add up.
Why expats often miss this
This catches a lot of newcomers out, for a very simple reason: it’s rarely explained.
You arrive, you’re covered by the health system, everything seems to be working — until a friend mentions in passing that you’re supposed to have “your” doctor on file, and you realise you’ve been paying more than you needed to.
Four things worth knowing:
- Declaring your médecin traitant is straightforward — you can fill in the form online via ameli.fr or your chosen GP can do it at your first appointment. It’s active almost immediately.
- You’re not locked in. You can change your médecin traitant at any time, with no need to justify why, whether you’ve moved house or simply prefer someone else.
- Not every specialist requires a referral. Gynaecologists, ophthalmologists, and psychiatrists (for patients aged 16–25) can be seen directly at the full reimbursement rate.
- •If you can’t find a GP willing to take you on — which isn’t unusual in areas with a shortage of doctors — CPAM has a process to help place you with one, rather than leaving you permanently in the lower reimbursement bracket through no fault of your own.
It’s really about reimbursement
Obviously, none of this is about the quality of care you receive: it’s about how the administrative system decides what it will pay for.
But that’s very often the case in France — the systems make sense once someone explains the logic behind them. It’s a good example of a small piece of admin that’s easy to overlook and can be mildly expensive to ignore.
One small piece of admin, one less headache
Small distinctions like this are everywhere in French admin. If you’d rather not learn them the hard way…
