A British visitor who is told in France that a GHIC or EHIC cannot be used is often facing a classification problem rather than a complete absence of rights. The decisive questions are whether the stay is genuinely temporary, whether the treatment is medically necessary rather than planned, whether the provider belongs to the French state healthcare system, and whether the card or its replacement certificate can be authenticated. A refusal to swipe or register the card is also different from a refusal to treat, and both are different again from a written refusal by a French health-insurance fund after the visitor has paid.

This distinction matters after Brexit. A Global Health Insurance Card (GHIC) or a qualifying European Health Insurance Card (EHIC) is not a French residence entitlement, a carte Vitale (French health-insurance card), an S1 registration, or travel insurance. It is evidence of a UK-funded cross-border right for medically necessary state healthcare during a temporary stay. If the card is rejected, the visitor should protect the medical position first, obtain a written reason, preserve every invoice and proof of payment, and choose the correct reimbursement route. The file should show the purpose and dates of the stay, the clinical reason for the treatment, the status of the provider, the documents presented, and the exact decision being challenged.

I. What a GHIC or EHIC should cover in France after Brexit

A. Is the treatment medically necessary during a temporary stay?

The first legal issue is not the nationality written on the passport. It is the connection between the treatment and the temporary stay. The UK’s official France travel-health guidance states that a British traveller needs a GHIC or a valid existing EHIC for medically necessary state healthcare in France. The same guidance warns that the card is not a substitute for travel insurance and does not normally cover private healthcare, private clinics, repatriation, changes to travel arrangements, or treatment classified as non-urgent. Those limits explain many apparent refusals.

The French Centre for European and International Social Security Liaison (CLEISS) guidance for visitors from the United Kingdom describes the post-Brexit position in similar terms. CLEISS explains that a person insured under the British social-security system may receive medically necessary care during a temporary stay in France. It also identifies the EU–UK Trade and Cooperation Agreement, including its social-security coordination protocol, as the source of provisions similar to the European coordination rules for medically necessary treatment during a temporary stay.

“Medically necessary” is wider than “life-threatening emergency”, but narrower than “any appointment that happens to take place while I am abroad”. A sudden fracture, infection, asthma attack, appendicitis, dental pain, pregnancy-related care, or an adjustment needed for a chronic condition may qualify. A treatment arranged because the visitor deliberately travelled to France for it is normally treated as planned care and must be analysed under a different authorisation route. The medical record should therefore describe why waiting until the return journey would have been medically unsafe or unreasonable, not simply repeat that the patient was uncomfortable.

The French distinction can be seen in Article R. 160-1 of the Code of Social Security. The rule is written for persons whose French or coordinated entitlement is established under Articles L. 160-1 and L. 160-2, but it gives a useful legal description of the temporary-stay concept. It provides:

« Les soins dispensés aux personnes bénéficiaires de la prise en charge des frais de santé au titre des articles L. 160-1 et L. 160-2 et aux personnes qui leur sont rattachées au sens des règlements européens qui s’avèrent médicalement nécessaires au cours d’un séjour temporaire »

In English, the important elements are care, medical necessity, and a temporary stay. The UK visitor’s cross-border right comes from the applicable UK–France coordination arrangement and the official implementation guidance, not from claiming French residence merely because treatment was received in France. Article R. 160-1 is therefore a useful framework for understanding the French administration’s vocabulary, while the GHIC or EHIC claim must still be matched to the visitor’s UK insurance status and the relevant post-Brexit route.

The same analysis prevents two opposite mistakes. A French resident who has moved to France cannot use a GHIC as a permanent replacement for registration with the French system. Conversely, a holidaymaker should not be rejected merely because they do not possess a French social-security number or a carte Vitale. The Service-Public explanation of the European Health Insurance Card makes the same structural point: the card operates for a stay in another country, and a person changing their usual country of residence must use the appropriate residence form rather than treating the EHIC as a residence document.

A move to France usually requires a different assessment. Article L. 160-1 of the Code of Social Security refers to a person who works in France or, without professional activity, resides there in a stable and regular manner. The French public-health route may involve employment, self-employment, a registered UK-funded S1, or another basis of cover. A person who has settled in France, is awaiting a carte Vitale, and presents a GHIC for routine resident care may be asking the wrong fund to pay. The fact that the person has a French address is not by itself decisive; the chronology, status, and competent system are decisive.

Territoriality is not absolute, either. Article L. 160-7 of the Code of Social Security states the French rule that illness and maternity benefits are not ordinarily served for care outside France, “sous réserve des conventions internationales et règlements européens”. That reservation is precisely why an international coordination instrument can create a temporary-stay entitlement without turning the visitor into a French resident. It is also why an administrator who cites only the general territorial rule, without checking the applicable UK coordination mechanism, may have reached an incomplete conclusion.

There is a practical test for the file. Ask four questions:

• Was the person in France for a holiday, family visit, business trip, study placement, or another stay with a defined temporary end date?
• Was the treatment needed because of the patient’s condition during that stay, rather than being the main purpose of the journey?
• Was the care supplied by a public or state-contracted provider participating in the French system?
• Was the British entitlement evidenced by a valid GHIC, a qualifying EHIC, or a Provisional Replacement Certificate (PRC) issued when the card was lost, stolen, forgotten, or unavailable?

If the answer to the first two questions is uncertain, the dispute is likely to concern eligibility. If the answer to the first two is clear but the card was not accepted, the dispute may instead concern documents, provider status, or a billing error. The legal response should be built around that distinction.

B. Why do French doctors or hospitals say that the card is not accepted?

“We do not accept GHIC” can describe several different situations. A private clinic may genuinely be outside the state system for the relevant service. A doctor may not know how to process a British card. An admission desk may require the card to be accompanied by identity evidence. A card may have expired, belong to another family member, or be unreadable. A hospital may ask for a payment guarantee before it has checked the entitlement. A provider may also mistake a planned consultation for medically necessary care. Each situation calls for a different remedy.

The British visitor should ask the provider to record the reason in writing, preferably on the estimate, invoice, admission note, or email. The document should identify the provider, the service, the date, whether the provider is public or private, the amount requested, and whether the refusal concerns treatment, direct billing, or the card itself. The words “cash payment required” are not the same as “treatment refused”. If the patient can safely receive care, paying while preserving the reimbursement claim may be more effective than arguing at the reception desk. If a genuine medical emergency exists, clinical treatment takes priority over the administrative discussion.

The applicable card must be personal. A partner’s card, a photograph without the relevant identifying information, or an old card that has been replaced may not establish the right. When the GHIC has been forgotten, lost, stolen, or has not arrived, the visitor should contact the NHS Overseas Healthcare Services route for a PRC. CLEISS explains that a French provider can use the PRC in the same way as the GHIC for the relevant temporary-stay claim, subject to its period of validity. The UK government’s healthcare-in-France guidance also separates temporary visitors, students, posted workers, and people living and working in France. A visitor should use the route that matches their actual status rather than selecting the most convenient document.

Provider status is a recurring fault line. The card is designed for medically necessary state healthcare on the same basis as persons insured in France. It does not promise that every private consultation, private hospital, excess fee, room upgrade, transport charge, or non-contracted practitioner will be free. A hospital can have a public emergency department while a particular consultant, clinic, or comfort service is billed separately. The admissions paperwork should be split into clinical treatment, statutory patient contributions, fee overrun, and optional services.

The Service-Public page for a foreign visitor in France is useful because it identifies the United Kingdom separately and explains the GHIC and PRC route. It also states that, in general, the French fund will not repay every euro spent. This is an important expectation-setting point: a partial reimbursement can be legally correct, while a zero reimbursement may require an explanation of the provider, treatment, status, or evidence.

A refusal to provide or process care must not be justified simply by a person’s nationality or by a protected characteristic. Article L. 1110-3 of the Code of Public Health opens with the rule: “Aucune personne ne peut faire l’objet de discriminations dans l’accès à la prévention ou aux soins.” That does not convert every billing disagreement into discrimination. It does mean that a provider should explain a genuine administrative or clinical reason instead of using “British” as a substitute for analysis.

Article L. 1110-5 of the Code of Public Health recognises the right to receive appropriate treatment, taking account of the patient’s health and the urgency of the intervention. The provision does not guarantee a particular hospital, tariff, or insurance result. It supports the immediate-care part of the response: if the condition is urgent, ask the provider to assess and treat the patient, while the card and reimbursement issue is documented separately.

A written reason is particularly valuable where the refusal is caused by a misunderstanding of the post-Brexit rules. The visitor can then send one focused request: confirm that the stay is temporary, identify the GHIC/EHIC/PRC, attach proof that the treatment was necessary during the stay, identify the provider’s state-system status, and ask the recipient either to process the entitlement or to state the precise legal and factual reason for refusing it. A general statement that “Brexit changed the rules” is not enough to determine the claim.

II. How to recover the money and challenge an unjustified refusal

A. What should a British visitor send to the CPAM or the NHS?

The best reimbursement file begins at the point of treatment. Before leaving the practice or hospital, obtain a dated clinical note, prescription, invoice, proof that the invoice was paid, and any discharge document. In France, a treatment form is called a feuille de soins, and a hospital discharge summary is a bulletin de sortie. Ask for those documents even if the provider says that the card cannot be processed. If the patient is too unwell, a family member or authorised representative should keep a written record and request the documents later.

The French route described by CLEISS generally involves sending the local Caisse primaire d’assurance maladie (CPAM), meaning the primary health-insurance fund for the place of treatment, the feuille de soins, the bulletin de sortie if there was hospital care, prescriptions, and a copy of the GHIC. CLEISS also asks for a permanent address and bank details and recommends keeping copies. The relevant official British-visitor page should be attached or cited only as an explanation of the route; it does not replace the individual decision on the file.

If the visitor paid the full amount, the evidence pack should include:

• a copy of the GHIC, EHIC, or PRC, together with the passport or other identity document used at admission;
• the entry and return dates, travel booking, accommodation evidence, and a short statement explaining why the stay was temporary;
• the medical report, prescription, referral, or discharge summary showing the diagnosis and why treatment was necessary during the stay;
• an original or electronic invoice identifying the patient, provider, date, treatment, and amount;
• a bank statement, card receipt, transfer confirmation, or other proof of payment matching the invoice;
• the provider’s written refusal, request for an advance, or explanation that it was private or outside the state system;
• a calculation table separating the amount paid, the amount claimed, statutory patient contributions, optional items, and any sum already reimbursed.

The invoice should not be rewritten to make it appear that private care was public care. If the provider supplied both covered and non-covered items, ask for a breakdown. If the provider refuses to issue a breakdown, record that refusal and send the documents that do exist. The legal question is whether the material identifies the care and the payment sufficiently for the competent fund to decide.

The French statutory framework recognises limits on what can be reimbursed. Article L. 160-8 of the Code of Social Security forms part of the provisions governing benefits in kind. Article L. 162-1-7 links the assumption of responsibility for acts and services to the applicable list and conditions. Article L. 160-13 addresses participation by the insured, including the fixed contribution associated with an unscheduled emergency visit. These provisions explain why the GHIC does not erase every patient contribution or additional fee.

The official case law record shows how evidence can determine the result. In the Tribunal judiciaire de Val de Briey, RG no 24/00108, judgment of 7 October 2025, the court considered an urgent treatment bill incurred during a tourist stay in Spain. The judgment stated: “L’ensemble de ces éléments permet de connaître la nature des soins dispensés à Mme [K] et de vérifier que le coût en a été réglé par l’assurée.” The point for a British visitor is practical: a matching medical document and payment record can make the nature of the care and the payment verifiable. The decision also shows that a dispute about a missing “perfect” invoice should be analysed against the evidence actually available, rather than ending automatically at the reception desk.

In the Tribunal judiciaire de Poitiers, RG no 23/00210, judgment of 3 February 2025, a French-insured patient who had paid for urgent treatment in Switzerland obtained coverage after the CPAM refused it. The court wrote: “Il résulte de ce texte que si l’assuré a dû s’acquitter d’une partie ou de la totalité des soins effectués dans un autre Etat membre de l’Union européenne ou partie à l’accord sur l’Espace économique européen ou en Suisse, il peut en demander la prise en charge par sa caisse à son retour.” That decision concerns a different insured-status configuration and should not be presented as a direct ruling on a British GHIC. It does, however, demonstrate the evidential and procedural logic of submitting a complete claim after advance payment.

The route after returning to the United Kingdom may be different from the route during the French stay. CLEISS says that, if the visitor did not request reimbursement during the stay, they should contact the NHS on returning to the UK. The UK government’s France health advice confirms the GHIC/valid EHIC starting point but warns that travel insurance may be required for amounts outside the statutory healthcare arrangement. The claimant should therefore ask the NHS Overseas Healthcare Services team which of the following is expected: a CPAM submission, a UK-side reimbursement request, or a PRC and retrospective entitlement check. The answer depends on the card, the person’s UK insurance status, and what the French provider did.

The two routes should not be confused with ordinary French resident reimbursement through a carte Vitale. A British pensioner who lives in France and has an S1, a worker employed in France, and a holiday visitor with a GHIC may all receive treatment in France, but they do not necessarily send the claim to the same institution or prove the same legal facts. A resident should not use the temporary-stay route to avoid registering the S1. A visitor should not be told to prove stable French residence when the claim is based on temporary cover.

A short covering letter should make the requested outcome explicit. For example: “I request processing of medically necessary state healthcare received during my temporary stay in France from [date] to [date]. I enclose my GHIC/PRC, proof of payment, the medical documents, the provider’s refusal, and the chronology. Please state the tariff and patient contribution applied, identify any excluded item, and issue a reasoned decision on any balance.” This wording creates a record of the exact request and invites the fund to distinguish eligibility, tariff, and evidence.

B. How should a CPAM refusal or a provider refusal be challenged?

Start by identifying the author of the refusal. If a receptionist says that a card cannot be entered, there may be no formal decision by a CPAM. The first step is a written request to the provider’s administration, with a copy to the relevant CPAM if the provider is seeking payment through the French system. If the patient paid and later receives a refusal from the CPAM or another competent fund, keep the envelope, portal timestamp, email header, and notice. The date and wording of the notification affect the available challenge.

When the refusal is a decision of a social-security body and falls within the mandatory prior-appeal category, Article L. 142-4 of the Code of Social Security requires a prior appeal before contentious proceedings in the matters referred to by the Code. That appeal is commonly addressed to the Commission de recours amiable (CRA), the amicable appeal commission, named in the decision or in the fund’s instructions. Do not send a generic complaint and assume that it preserves every right: identify the challenged decision, its date, the claim period, the amount, and the legal result requested.

Article R. 142-1-A of the Code of Social Security gives a general two-month period for the prior appeal and the contentious appeal from notification of the contested decision, with an important condition: the period is enforceable only if the notification mentions the period and the available remedies. The provision says: “le délai de recours préalable et le délai de recours contentieux sont de deux mois à compter de la notification de la décision contestée”. The safest practice is to act immediately, even where the notice appears incomplete, and to obtain advice on the effect of an incomplete notification rather than waiting for a deadline argument.

The CRA submission should be evidence-led. Put the facts in date order: arrival in France, reason for the stay, onset of symptoms, consultation or admission, documents shown, treatment provided, amount paid, request for reimbursement, and refusal. Then separate the legal points:

• temporary stay and British insurance status;
• GHIC, qualifying EHIC, or PRC validity;
• medical necessity and absence of a planned-treatment purpose;
• public or state-contracted provider status;
• tariff, patient contribution, excess fee, and optional items;
• proof of the treatment and proof of payment;
• the precise sum requested and the alternative result if only part of the bill is covered.

If the fund says that French resident cover was required, answer with the temporary-stay evidence and the post-Brexit coordination source. If it says that the treatment was planned, answer with the medical chronology and the reason it could not be deferred. If it says that the provider was private, ask for the provider classification and an itemised calculation rather than arguing about the patient’s passport. If it says that the card was invalid, attach the PRC or ask the UK authority to confirm the entitlement for the treatment date.

The case law also illustrates why a refusal cannot be evaluated without the tariff and provider facts. In the Tribunal judiciaire de Marseille, RG no 23/00406, judgment of 1 December 2025, the court dealt with urgent treatment at a private Spanish clinic and a dispute about additional reimbursement. It stated: “C’est donc à juste titre que la [10] a fait application de la législation française qui prévoit une prise en charge forfaitaire des actes médicaux, dans la limite des tarifs forfaitaires en vigueur.” The decision is a warning against promising automatic repayment of a private provider’s full invoice. It is also a reason to ask for the actual tariff calculation and the precise choice of reimbursement basis.

Another recent decision, the Tribunal judiciaire de Valenciennes, RG no 25/00315, judgment of 27 May 2026, concerned foreign dental treatment and a refusal based on an alleged late claim. The court accepted evidence that an earlier submission had been stamped by the fund’s reception service and ordered reimbursement within the regulatory conditions. The lesson is transferable even though the facts were not a British GHIC case: send the claim through a traceable channel, preserve the receipt, and do not let an internal registration error erase proof of timely delivery.

The social-security court stage requires care. A CRA rejection is not the same as a provider’s refusal, and a court claim against the wrong defendant or without the prior appeal may fail before the merits are reached. The correct court, route, time limit, and claim classification depend on the decision and the nature of the benefit. A British visitor should obtain the full refusal, the CRA response, and the evidence of the temporary stay before starting proceedings. The claim should ask for a defined amount or a defined recalculation, not merely a declaration that Brexit was unfair.

The public-health rights reinforce, but do not replace, the reimbursement claim. Article L. 1111-2 of the Code of Public Health concerns the patient’s right to information about their health and the proposed care. Article L. 1111-4 protects consent to medical treatment. These provisions can support a request for a clear explanation, medical records, and a decision that distinguishes treatment from billing. They do not themselves guarantee that an excluded private charge will be reimbursed by the French fund.

Where the refusal appears discriminatory, preserve the exact words used, the date, the names or roles of the people involved, and any witnesses. Ask the institution to investigate and provide its written position. A claim under the non-discrimination rules needs facts showing that the refusal was linked to a protected ground, not simply evidence that the provider misunderstood a foreign card. A legally precise complaint is more useful than a general accusation because it allows the recipient to respond to the actual conduct.

The final file should contain a one-page schedule. The first column lists each treatment and date. The second identifies the provider and whether it was public, contracted, or private. The third records the amount charged and paid. The fourth identifies the document proving the charge. The fifth states the reimbursement requested and the reason for any exclusion. The last column records each submission date, response, and deadline. This format exposes whether the dispute is about eligibility, medical necessity, provider status, tariff, evidence, or procedure.

The British visitor should also notify their travel insurer if there is any possibility of private fees, repatriation, accommodation changes, or an excess not paid under the GHIC arrangement. A GHIC and travel insurance are complementary. Submitting the same expense to two payers without explaining the overlap can create a recovery dispute. State what the French fund has paid, what the NHS has paid, and what the insurer has paid or declined.

Conclusion

A GHIC or EHIC refusal in France is not resolved by the word “Brexit” alone. The file must establish a genuinely temporary stay, medically necessary rather than planned care, a valid British entitlement, and a provider within the state-healthcare framework. It must then separate treatment from optional services, statutory patient contributions, private fees, and repatriation. A British visitor should obtain a GHIC, EHIC, or PRC record, request a written reason, preserve the medical and payment documents, and use the CPAM or NHS route that matches the actual status.

If a French fund issues a refusal, identify the notification date and follow the prior-appeal instructions, generally through the CRA where that route applies. Attach a chronology, an indexed evidence pack, and a precise calculation. If the refusal is a provider’s administrative statement rather than a formal fund decision, challenge the provider’s classification and ask the CPAM or UK authority to confirm the entitlement. The strongest claim is specific: it identifies the treatment, the temporary stay, the card, the provider, the amount, the legal basis, and the remedy requested.
