Trans Americans Moving to France: Hormones, CPAM, and Keeping Treatment Going

You booked the flight, you have three months of hormones in your carry-on, and you assumed a French doctor would simply continue what your US endocrinologist started. Trans healthcare in France is well covered and, since July 2025, properly mapped out. It still does not hand off cleanly from the American system. The handoff has two chokepoints: the pharmacy counter, where your US ordonnance has no standing, and the prescriber rules, which decide who is allowed to restart your treatment. This article is for informational purposes only and is not medical or administrative advice; verify current requirements with your local CPAM or a qualified professional.

Will your hormone prescription survive the move?

A prescription written by a US doctor cannot be dispensed at a French pharmacy, so the number that matters is not how many months you packed. It is how many weeks stand between your arrival and an appointment with a French doctor who is legally allowed to write the prescription you need.

Two things stretch that gap. The first is the doctor shortage: registering a médecin traitant in France is slow in most départements, and the coordinated care pathway runs through that doctor. The second is specific to testosterone. French marketing authorisation reserves the first prescription to a short list of specialists, which means the appointment you actually need is not with a general practitioner at all.

Packing extra is the obvious hedge, and French customs caps what you may carry. Those limits, and the paperwork for controlled substances, are covered in our guide to bringing US prescription medications through French customs. What a large supply cannot solve is the prescriber question, which is where this article starts.

Who can write your first French prescription

For testosterone enanthate, sold in France as Androtardyl, the initial prescription is reserved to 6 categories of specialist. The Ordre national des pharmaciens publishes the dispensing conditions on Meddispar, and pharmacists apply them to the letter.

The renewal line is the one that catches people out. A French doctor can renew testosterone, but the pharmacy has to see the specialist's original prescription every single time, and that requirement does not expire with the prescription itself. Photograph that ordonnance, keep the paper somewhere permanent, and carry it to every refill. A pharmacist asking for it is not being difficult; the requirement is written into the dispensing conditions rather than left to anyone's judgment.

These conditions attach to the testosterone specialities. Look up your own product on Meddispar before assuming a GP can write your first French prescription, because the answer differs by molecule and by brand.

What the Haute Autorité de Santé changed in July 2025

On 18 July 2025 the Haute Autorité de Santé published France's first national clinical guidelines on the medical care of trans adults, adopted by its board on 17 July 2025. The recommendation covers what to do when someone requests transition, hormone prescription, surgery, psychological support, other care, and the fluidity of transition pathways including detransition and retransition.

Two features matter for an American arriving mid-treatment. The HAS published a fact sheet written specifically for general practitioners, which tells you where it expects the pathway to sit. It also published an English-language version of the guidelines, which is unusual and practically useful: you can hand it to a French doctor who is willing but unfamiliar. A second volet covering minors was still at the scoping stage as of May 2026.

One thing worth knowing before the first consultation. Assurance Maladie's guidance to physicians notes that prescribing hormone treatment outside the terms of the marketing authorisation obliges the doctor to inform the patient of the expected benefits and the risks. Hormone therapy in a transition context is largely prescribed off-label in France. A doctor raising this is following the rule, not stalling.

ALD 31, and what 100 percent actually covers

Assurance Maladie examines every application for long-term condition status in a transition pathway under ALD 31, the "hors liste" category, citing article L. 322-3-4 of the Code de la Sécurité sociale. Care connected to it is then reimbursed at 100 percent of the Sécurité sociale base rate.

What the three criteria require

ALD 31 is not automatic. Three conditions must all be met: a severe, progressive or disabling form of a serious illness; treatment expected to run longer than six months; and a particularly costly package of care. That last test is mechanical. The package counts as costly if it contains at least three of five elements, and regular medication or regular appareillage is compulsory among them. The other four are hospitalisation, repeated medical procedures, repeated laboratory tests, and repeated paramedical care.

Your médecin traitant files the protocole de soins. You cannot file it yourself, which is one more reason the search for a doctor is the first task rather than the third.

What 100 percent does not mean

It means 100 percent of the Sécurité sociale base rate, not 100 percent of the bill. Dépassements d'honoraires, the amounts practitioners charge above the agreed tariff, remain yours. A mutuelle is what closes that gap, and it is worth arranging before you need surgery rather than after.

Worth correcting one piece of outdated American guidance while we are here: France removed transition care from ALD 23, the psychiatric long-term condition category, by a decree Assurance Maladie dates to 8 February 2010. Anything describing French transition care as a psychiatric pathway is sixteen years behind.

The document problem: your passport, your file, and two systems that will not agree

What changed on the US side

Executive Order 14168, issued on 20 January 2025, ended the X marker on US passports and Consular Reports of Birth Abroad. The State Department now issues only an M or F marker matching sex at birth and, since the Supreme Court stayed the June 2025 Massachusetts injunction in Orr v. Trump on 6 November 2025, will not honour attestations requesting a preferred marker. Passports already issued remain valid until they expire.

That last sentence is the planning point, and it is easy to miss. Your entire French residence file is anchored to your passport. If that passport expires two years into your stay and the replacement comes back with a different marker than your titre de séjour, the mismatch propagates to your carte de séjour, your CPAM record and your bank. Check your passport expiry against your visa timeline before you leave, not after.

To replace a passport that lists a sex other than your sex at birth: within one year of issue, Form DS-5504 by mail, no passport fee unless you want the 60 dollar expedited service, and a new photo if the passport is more than six months old. Past one year, Form DS-82 if you are eligible to renew, otherwise Form DS-11 in person, with all fees payable. Orr v. Trump was still live when this was written, so confirm the current position on the State Department page before filing anything.

What the French procedure requires

France's own route is comparatively light. Changing the sex mention on French civil status requires no medical treatment, no surgery and no sterilisation, and the official procedure states plainly that their absence cannot be used to reject the application. It is a request on plain paper to the tribunal judiciaire, a lawyer is optional, and proof can be brought by any means: written statements from people who know you, messages, screenshots, a membership card in the right name. The request now carries a 50 euro contribution pour l'aide juridique, paid as an electronic timbre fiscal, waived if you qualify for legal aid. Once the decision is final, the procureur de la République has the change entered in the margin of the birth record within 15 days.

The jurisdiction gap nobody warns Americans about

Here is the part worth naming plainly, because it is the single most common wrong assumption. The French procedure sets out which court is competent in three situations: people born in France, French citizens born abroad, and refugees or stateless persons holding an OFPRA certificate. An American citizen born in the United States fits none of those three, and a French court has no power over a birth record held by a US state.

Whether a French judgment would help you at all, and which court could hear it, is a question for the tribunal judiciaire covering your commune or a Maison de justice et du droit, and it is worth asking before you build a timeline around it. Do not assume the French route is open to you because it is open to your French partner. Any US court order or amended record you do hold will need apostille and certified translation before a French administration will look at it.

If the sequencing here is starting to look like the actual problem, that is the correct read, and it is exactly what a consulting call is for: 30 minutes to map your dates against each other, and a written plan within 48 hours, instead of four government websites and a guess.

If you are moving as a couple, the same matching problem reaches your marriage record, and our guide to whether your marriage travels with you covers which French rule applies and what the prefecture actually asks to see.

What goes wrong between the plane and the first French ordonnance

The most expensive mistake in this sequence is booking a GP appointment first when your treatment is testosterone. Four patterns recur, and none of them involves hostility.

Sequencing. People book a GP, wait three weeks, and learn at the appointment that this doctor cannot initiate their treatment. The specialist search then starts from zero. The shortage that makes a médecin traitant hard to find applies to endocrinologists too.

The renewal document. Treatment runs fine for a year, then a pharmacy declines a refill because the specialist's initial prescription is in a drawer in Ohio. Nothing about that is fixable at the counter.

The file mismatch. CPAM, the prefecture and your pharmacy build their records from different documents at different moments. Where a name or marker differs between them, the usual result is not a refusal but a file that stalls silently and needs a person to unblock it. Opening your CPAM file with documents that already agree is far cheaper than correcting it later.

Assuming an American letter travels. A letter from your US physician confirming treatment history carries no legal weight at a French pharmacy. It carries real clinical weight in a first consultation. Bring it translated, and expect it to inform a doctor rather than authorise anything.

What to do before you get on the plane

Book the French specialist consultation from the United States, before you fly, because it is the single step everything else waits on.

Plenty of people handle the rest alone. If your documents already agree with one another, your residence permit is straightforward, and you are moving to a city with a teaching hospital, this is a scheduling problem you can solve with a calendar, a translated medical summary and private cover for the months before CPAM. It gets harder when the pieces interact: a passport renewal landing inside your first permit renewal, a treatment that cannot lapse, a CPAM file already stalled on a name mismatch. Those are not four problems. They are one problem with four deadlines, and the order you take them in decides whether it works.

If that is your situation, book a consulting call. Thirty minutes with Maxime, and a written plan in your inbox within 48 hours setting out the sequence and the dates, so your treatment does not become the thing that waits.

FAQ

Can I just bring a year of hormones instead of dealing with this?

French customs sets limits on personal medication quantities, and those limits are separate from the prescriber rules. A large supply only postpones the problem, because both the specialist appointment and the protocole de soins take time to arrange. Use the supply to buy scheduling room, not to delay entering the French system.

Do I need CPAM before a French doctor will prescribe?

No. A doctor can prescribe before your Assurance Maladie file is open. What changes is who pays: until your rights are active you cover the consultation and the medication yourself. ALD 31 status, which brings reimbursement to 100 percent of the base rate, requires a protocole de soins filed by your médecin traitant.

Will a French doctor require a psychiatric assessment first?

The HAS guidelines published on 18 July 2025 position the general practitioner centrally and treat psychological support as one component rather than a gateway. France also removed transition care from the psychiatric ALD category in February 2010. Individual practice still varies, and the published guidelines are a reasonable thing to raise.

My passport and my French documents show different names. Does that block the pharmacy?

It rarely stops a single dispensing. It bites at renewals and at the prefecture, where the passport anchors the whole residence file. Tell your CPAM about any civil status change as soon as it happens, which is the final step the French procedure sets out after a court decision, and keep certified copies of everything recording the change.

Is transition-related surgery covered?

Only procedures listed in the CCAM or NGAP can be reimbursed by Assurance Maladie, and some transgender surgical procedures require prior agreement, an accord préalable, whether or not you hold ALD 31. Because ALD 31 covers 100 percent of the base rate only, surgeon dépassements d'honoraires remain payable by you unless a mutuelle absorbs them.
