For a British national settling in France after Brexit, the first healthcare obstacle is often not a medical question but an administrative one: the French health service asks for a social-security number, while the number is normally generated through the very registration that the applicant is trying to complete. Without a final number, the applicant may be unable to open an Ameli account or order a carte Vitale, yet treatment and reimbursement cannot simply be placed on hold. A delayed file can also become expensive when a hospital, doctor or pharmacist asks for evidence of current cover.<\/p>\n
This article addresses a precise situation: a British resident in France has a lawful basis for French healthcare, or believes that he or she has one, but the Caisse primaire d\u2019assurance maladie<\/em> (CPAM, the local primary health-insurance fund) has not issued a social-security number, has issued only a temporary number, or has returned the file as incomplete. The route depends on work, residence, a United Kingdom-issued S1 form, and the date and quality of the evidence submitted. It is not the same as buying a short-term policy, using a GHIC during a holiday, or asking for a French residence permit.<\/p>\n The practical objective is therefore twofold: establish the legal basis for affiliation and create a dated evidential record that allows an incomplete or silent file to be challenged. The rules below combine the post-Brexit position with the French Code of Social Security, current French administrative guidance and United Kingdom guidance. They are especially important where a missed document, an incorrect assumption about the three-month period, or confusion between a temporary identification number and a final number has stopped the file.<\/p>\n A social-security number is not a visa, a residence card or proof of nationality. In France it is the unique identification number assigned in the national inter-regime register, commonly called the num\u00e9ro d\u2019inscription au r\u00e9pertoire<\/em> (NIR). Affiliation is the legal attachment to a French social-security scheme. These two ideas are related but not identical: a person may have a right to healthcare before the final NIR is printed on a card, and an administrative file may first receive a temporary identification number.<\/p>\n The starting point is Article L. 160-1 of the French Code of Social Security. It states that \u201cToute personne travaillant ou, lorsqu’elle n’exerce pas d’activit\u00e9 professionnelle, r\u00e9sidant en France de mani\u00e8re stable et r\u00e9guli\u00e8re b\u00e9n\u00e9ficie\u201d of healthcare costs being covered in the statutory conditions. The current L. 160-1 text on L\u00e9gifrance<\/a> is the primary legal source. For a British national, \u201cstable\u201d and \u201cregular\u201d residence must be demonstrated within the French rules; the fact that the applicant is British does not, by itself, create an entitlement or remove one.<\/p>\n After Brexit, a British person is generally treated as a third-country national for the ordinary French immigration analysis, subject to the Withdrawal Agreement and any applicable social-security coordination route. The document may be a residence permit issued under the Withdrawal Agreement, another valid French residence document, a long-stay visa where appropriate, or evidence of an employment basis that makes the person subject to French insurance. A French residence document and French healthcare affiliation are separate files. Holding one does not automatically prove that the other has been completed, and a CPAM may require a copy of the document even where the prefecture has already accepted the applicant\u2019s residence position.<\/p>\n There are several common routes.<\/p>\n Article L. 160-5 deals with the person who declares that he or she does not already receive healthcare cover. It provides that cover is supplied by the caisse once the person has proved identity and stable, regular residence. Read the wording of Article L. 160-5 on L\u00e9gifrance<\/a> together with Article L. 160-1; neither article says that a British applicant is rejected merely because the applicant is British.<\/p>\n The residence tests need to be handled carefully. Article R. 111-2 describes stable residence by reference to the home or principal place of stay and, for healthcare benefits, generally requires presence in France for more than six months during the calendar year. The current Article R. 111-2<\/a> also permits residence to be proved by any means. That is not the same calculation as the usual three-month waiting rule applied to an inactive person opening rights under PUMa. The applicant should therefore identify the legal route first and then answer the evidence question for that route, rather than copy a six-month or three-month figure into every application.<\/p>\n For an applicant who is not working and is relying on residence, Article D. 160-2 is central. It allows the applicant under Article L. 160-5 to provide proof of uninterrupted residence in France for more than three months, subject to the categories and exceptions in the provision. The text of Article D. 160-2 on L\u00e9gifrance<\/a> must be checked at the date of the application, because the exact exception may matter. A person with an S1 or another coordination document should not be advised to use the residence route without first checking which institution is responsible.<\/p>\n The Court of Cassation illustrates why dates and evidence matter. In Cour de cassation, Second Civil Chamber, 3 June 2021, no. 20-10.687, ECLI FR:CCASS:2021:C200546<\/a>, the Court rejected an appeal by an applicant who had arrived in France on 10 March 2016 and applied on 23 March 2016 without proving more than three months of uninterrupted residence or falling within the relevant exception. The Court stated that the rules \u201cs’appliquent sans distinction de nationalit\u00e9\u201d. That decision does not concern Brexit and is fact-specific, but it is a useful warning: the CPAM can lawfully examine the qualifying date and the applicable category, and an applicant should not assume that a residence intention is enough.<\/p>\n The decision also records the phrase \u201cr\u00e9sidence en France ininterrompue de plus de trois mois\u201d. That is not an instruction to wait passively. It means that the file should show when the qualifying period began, what evidence covers it, and why any absences do or do not interrupt the relevant test. A British resident who has moved between a French home and the United Kingdom should prepare a short chronology rather than send isolated utility bills with no explanation.<\/p>\n Finally, the Code now contains Article L. 160-1-1 concerning possible financial participation by certain adults who are not covered through work and who rely on residence-based protection. The Article L. 160-1-1 text on L\u00e9gifrance<\/a> should be checked with the latest administrative implementation before any payment or declaration is made. It does not turn the social-security number into a fee for a card, and it does not remove the need to establish identity, lawful stay and the responsible route.<\/p>\n For a person born outside France, the first practical application is usually a request to open healthcare rights using the French form Cerfa S1106, \u201cDemande d\u2019ouverture des droits \u00e0 l\u2019assurance maladie\u201d. The current Ameli guidance for a person born abroad applying for a social-security number<\/a> explains that opening healthcare rights is the first step toward obtaining the number. The form should be completed consistently with the residence document, tax address, employment or pension status and any S1 registration. Inconsistent dates are a frequent reason for a request for further information.<\/p>\n A robust file usually contains the following, adapted to the applicant\u2019s route:<\/p>\n The civil-status document deserves particular attention. The CPAM sends identity data for certification before a final number can be confirmed. A document that is cropped, unreadable, inconsistent with the passport, or missing a required translation can leave the file in a temporary state. The applicant should not send an irreplaceable original unless the authority expressly requires it and a secure method is available. Keep a complete PDF copy, a list of the pages sent, the postal receipt or electronic submission receipt, and the date on which delivery is shown.<\/p>\n French terminology is important when reading a response. A num\u00e9ro d\u2019identification d\u2019attente<\/em> (NIA) is a temporary identification number. A num\u00e9ro d\u2019inscription au r\u00e9pertoire<\/em> (NIR) is the final social-security number. An attestation de droits<\/em> is a certificate showing current healthcare rights. A carte Vitale<\/em> is the electronic health-insurance card used by providers to identify the insured person and transmit a reimbursement claim. These documents do not have the same legal or operational function.<\/p>\n According to the current Ameli foreign-born procedure, the NIA can allow temporary identification and reimbursement but does not allow the holder to create an Ameli account or receive a carte Vitale. The page states that the NIA is usable for a limited period, indicates a nine-month period for the temporary identification process, and warns that missing civil-status evidence can lead first to a suspension of reimbursements and later to removal of rights. The timing should be read from the current Ameli page<\/a> rather than from an old forum post or a provider\u2019s estimate.<\/p>\n United Kingdom guidance gives a broader practical estimate that a temporary number may arrive after one to three months and that the carte Vitale can take six months or longer. That estimate is not a guarantee and cannot override the current French process. The two statements can be reconciled by understanding that the first number, the final NIR and the physical card are separate stages. The applicant should ask the CPAM which stage has been reached and what document is missing, instead of asking only \u201cWhere is my card?\u201d<\/p>\n While the final number is pending, treatment should not automatically be postponed. The United Kingdom Government explains that, before the card is available, a person may use the number already supplied and ask the healthcare provider for a feuille de soins<\/em>, the paper treatment form sent to the CPAM for reimbursement. If an attestation of rights is available, provide it to the doctor, hospital or pharmacy. Keep invoices, prescriptions, proof of payment and the medical provider\u2019s details. A GHIC is designed for medically necessary treatment during a temporary stay; it is not a substitute for registering French residence-based cover.<\/p>\n The entitlement to a card follows the verified attachment to a compulsory health-insurance body. Article R. 161-33-1 describes the carte Vitale as an electronic means of identification and records the data needed for identification and use of health-insurance services. The Article R. 161-33-1 text<\/a> should be read with Article R. 161-33-2, under which each compulsory health-insurance organisation issues a card to the people attached to it while checking identity and the right to healthcare. The exact words of Article R. 161-33-2<\/a> are that the organisation issues the card \u201cen s’assurant de l’identit\u00e9 du titulaire de la carte et de ses droits \u00e0 la prise en charge des frais de sant\u00e9\u201d. A card request is therefore normally the last stage, not the first proof of entitlement.<\/p>\n Once the CPAM confirms the final NIR, the Ameli card procedure<\/a> explains how to order the card through an Ameli account or the paper route. The applicant should check the name, date of birth, address and photograph instructions before submission. If the card is refused because the civil-status data do not match, the remedy is to correct the underlying identity record; repeatedly ordering a card will not cure a defective NIR file.<\/p>\n A British applicant should also separate the healthcare question from private insurance. Private insurance may protect the waiting period, but it does not itself cause a French NIR to be issued. It may, however, be sensible while the CPAM file is being processed, particularly where a visa or residence route requires continuous cover. Keep the policy and any claims correspondence because they may explain why reimbursement was sought elsewhere during the administrative delay.<\/p>\n The first step is to identify what the CPAM has actually done. \u201cWe are waiting for another service\u201d is not the same as a written refusal. \u201cYour file is incomplete\u201d is not necessarily a final decision. A letter stating that the applicant does not meet the conditions, a decision closing the application, or a refusal to reimburse is different again. The legal route and the time limit depend on the document and the date it was notified.<\/p>\n Ask for a written position if the file has stalled. Write a focused message with the submission date, the delivery reference, the applicant\u2019s temporary number if one exists, the surname and given names exactly as used in the passport, and a schedule of documents. State that the request is for a determination of affiliation and processing of the social-security identification, not merely a request for general information. If the CPAM asks for a document that has already been sent, attach the delivery proof and identify the page rather than resending an unexplained bundle.<\/p>\n For a formal refusal concerning the application of social-security legislation, the ordinary preliminary challenge is a recours pr\u00e9alable<\/em>, an obligatory prior administrative appeal. It is addressed to the commission de recours amiable<\/em> (CRA), the amicable appeals commission within the fund. Article R. 142-1 of the Code of Social Security states that the CRA must be seized within two months from notification of the decision being challenged. See the Article R. 142-1 text on L\u00e9gifrance<\/a>. The two-month period is a procedural deadline, not a suggestion to wait until the file is convenient.<\/p>\n The CRA submission should be headed as an appeal and should identify the decision, the date of notification, the legal basis, the facts, the evidence and the outcome requested. A British resident can ask the CRA to recognise the applicable route, order the fund to reconsider the opening of rights, take into account proof of regular residence or an S1, correct an identity error, and process reimbursement while the identification stage is completed. The request should not ask the CRA to decide an immigration application that belongs to the prefecture, or a tax issue that belongs to the tax administration. Keep the issues within the CPAM\u2019s competence.<\/p>\n Send the appeal by a method that gives a certain date of receipt, such as registered post with delivery evidence or an electronic channel that provides an acknowledged submission. If the decision does not tell you where to send the CRA appeal, use the address of the relevant CPAM and ask for forwarding to its CRA, while retaining proof. Do not rely only on an unlogged telephone call. A call can help locate a file, but it rarely proves the content of the request or stops a deadline.<\/p>\n Silence must also be dated. Article R. 142-6 provides that the absence of a decision by the CRA after the applicable period is treated as a rejection and sets out the point from which that period runs. Consult the current Article R. 142-6 text<\/a> before calculating the next appeal. The applicant should record the date the CRA received the appeal, the date of any request for further evidence, the date that evidence was received, and the date on which the implied decision arises. A spreadsheet with document names and dates can be more useful than a long narrative.<\/p>\n The compulsory preliminary appeal is connected to the jurisdiction rules in Articles L. 142-1 and L. 142-4. Article L. 142-1<\/a> identifies disputes concerning the application of social-security legislation, while Article L. 142-4<\/a> makes the prior appeal a condition in the cases covered by the Code. If the CRA rejects the challenge, or its silence amounts to rejection, the next step is generally an action before the judicial court\u2019s social division, commonly called the p\u00f4le social du tribunal judiciaire<\/em>. The competent court and time limit should be checked against the notification and the type of dispute.<\/p>\n The application to the court should contain a clean procedural chronology: arrival in France, status, application to the CPAM, every request for further information, delivery dates, the CPAM decision, the CRA appeal, the CRA response or the date of implied rejection, and the relief requested. Attach a paginated bundle. Put the decisive documents first: passport, residence document, proof of address and presence, work or S1 evidence, birth record, Cerfa S1106, submission proof, CPAM correspondence, CRA appeal and CRA proof of receipt.<\/p>\n Do not frame every delay as discrimination. A refusal based on an unreadable birth certificate, a missing translation or the absence of proof of regular stay may be corrected by completing the file. A refusal that applies a rule to a person who satisfies the conditions, ignores a dated document, confuses S1 coordination with PUMa, or treats a temporary number as proof that no right exists may require a more developed appeal. The distinction affects both credibility and the evidence required.<\/p>\n The second relevant Court of Cassation decision is Cour de cassation, Second Civil Chamber, 10 October 2019, no. 18-20.725, ECLI FR:CCASS:2019:C201217<\/a>. It concerned a Gabonese applicant and family benefits, not a British resident after Brexit, so it is not a direct answer to this article\u2019s situation. It is nevertheless useful because the Court recorded a CPAM affiliation under regime 802 that had resulted in healthcare cover \u201csur le seul crit\u00e8re de sa r\u00e9sidence stable et r\u00e9guli\u00e8re\u201d. The case demonstrates that the institution\u2019s classification of the file and the legal basis for cover can matter. It should be cited as an illustration, not as a substitute for checking the France\u2013United Kingdom coordination rules.<\/p>\n Where an international agreement or coordination instrument applies, put it at the front of the appeal. The same 2019 decision reproduces the reasoning that, where international social-security conventions exist, the applicable bilateral provisions must be considered before domestic rules. That passage arose in a different bilateral relationship and must not be mechanically transferred to the United Kingdom. The correct approach is to identify the document actually held by the applicant, the risk covered by it, the competent State and the French registration step still required.<\/p>\n The appeal should use precise relief. Examples include: \u201crecognise that my application falls under the employment route from [date]\u201d; \u201cregister the attached S1 and confirm the French file number\u201d; \u201creconsider the PUMa application from the date on which the statutory residence condition was met\u201d; \u201cissue or maintain the temporary identification needed for reimbursement\u201d; or \u201ccorrect the civil-status data and resume certification of the NIR\u201d. A vague request to \u201cgive me my carte Vitale\u201d may invite a response that the card cannot yet be issued, even where the underlying healthcare-rights question remains unresolved.<\/p>\n A pending number can create three separate risks: immediate medical bills, a break in proof of healthcare cover, and a later dispute about the date from which rights or reimbursement should run. Deal with each risk separately. For treatment, use the temporary number or attestation if supplied, ask for a feuille de soins where electronic transmission is not possible, and keep proof of submission. For residence, keep the valid permit, renewal receipt and prefecture correspondence. For cross-border coordination, keep the S1, pension letter, United Kingdom decision or other document showing which State is responsible.<\/p>\n A CPAM file is not an immigration file. A British national with a valid Withdrawal Agreement residence card may still have to complete healthcare registration. Conversely, an S1 may identify the State that funds healthcare without replacing the French evidence needed for residence, identity or a local number. Do not let a health-insurance officer\u2019s request for a residence document be treated as a finding that the residence permit is invalid. If the two administrations give inconsistent answers, request the position in writing from each body and compare the dates and legal basis.<\/p>\n The six-month residence concept in Article R. 111-2 also matters to people who travel frequently between France and the United Kingdom. Keep evidence that shows the actual pattern of presence: travel records, French utility use, medical appointments, school or work records and other dated documents. This is not an invitation to manufacture evidence. It is a way to answer a precise question about the principal place of residence and the time spent in France. A false address or a selective travel history can damage both the health file and the immigration or tax position.<\/p>\n For an S1 holder, provide the original or officially issued document in the format required by the responsible authority, plus a copy and proof of submission. Confirm whether the CPAM has registered the S1 or merely scanned it into an unresolved file. Ask for the temporary number, an attestation of rights and the next step for the final NIR. A person drawing a United Kingdom State Pension should not assume that the pension letter itself is the S1; obtain the actual coordination document through the competent United Kingdom service.<\/p>\n For a residence-based application, establish the date on which the three-month condition was reached and show why the applicant falls within the PUMa route. If the applicant worked, studied, joined a covered family member or falls into another exception, identify that fact and supply the supporting document. The list in Article D. 160-2 is important because it may change the answer to the waiting-period question. An applicant who has already qualified should not submit a new application as if the clock started again simply because the CPAM returned the first file for a missing copy.<\/p>\n For a work-based application, check whether the employer has made the declaration and whether the social-security body has received it. Ask the employer for the declaration reference and correct any mismatch in the surname, date of birth or place of birth. A payroll record that uses an old temporary number can create a second file. Employers and applicants should use one consistent identity format, including hyphens and middle names, and explain any difference between the passport and civil-status document.<\/p>\n When a provider refuses treatment because there is no card, calmly distinguish the card from the right. Show the attestation or number, ask whether the provider can create a paper feuille de soins, and document any refusal that causes a financial loss. The provider cannot decide the CPAM appeal, but its written explanation can prove why reimbursement was delayed. For urgent care, do not postpone necessary treatment to wait for a card; address the funding and reimbursement evidence afterwards.<\/p>\n The French administrative record should be built in a way that a court can read quickly. Use a file name such as \u201c2026-08-28 CPAM appeal \u2013 birth certificate\u201d for each PDF, keep a contents page and avoid sending multiple versions without explaining which is current. Translate key correspondence into a short English summary for the applicant\u2019s own use, but submit French forms and documents in the form the CPAM requires. If a translation is legally required, use the appropriate certified translator and retain the certification.<\/p>\n There is no automatic entitlement to retrospective reimbursement for every medical expense incurred before affiliation is finalised. The answer may depend on the legal route, the date the qualifying conditions were met, the date of care and the applicable coordination rules. Ask for a decision on the date of opening of rights, not only a card. If the CPAM has accepted the underlying right but has not finalised the NIR, ask how claims submitted with the temporary number will be processed and whether a later correction is required.<\/p>\n The same care applies to the Ameli account. A person with only an NIA may be unable to create one, so an inability to log in is not proof that no healthcare right exists. Use the CPAM\u2019s postal or telephone channel, or an authorised representative where appropriate, and ask for a written confirmation. Once the NIR is validated, follow the Service-Public guidance on obtaining an attestation of rights<\/a> and the Ameli card process. Never disclose a full number publicly or to an unverified caller claiming to be from the card service.<\/p>\n Cross-border travel adds a final practical issue. A British resident who returns to the United Kingdom for a short visit should carry evidence of French registration or the S1 position and private cover where relevant. A GHIC does not prove French residence and does not replace the French application. A person who has moved back to the United Kingdom should notify the relevant institutions rather than continue to use a French card on the assumption that the address is unchanged. The fact pattern determines which State is responsible.<\/p>\n If the CPAM ignores a properly documented CRA appeal, the applicant should not allow the court deadline to expire while sending repeated informal messages. Put the CRA receipt and the presumed rejection date into the diary, calculate the judicial time limit from the applicable notification or legal rule, and obtain advice on the claim before that date. The court can review the social-security decision; it cannot turn an incomplete immigration or civil-status file into a complete one without the underlying evidence.<\/p>\n The best challenge is usually narrow and evidence-led. It states the applicant\u2019s status, names the statutory route, identifies each condition, links each condition to a document, and explains the precise error in the CPAM response. It also acknowledges facts that are genuinely unfavourable, such as a recent arrival or an absence of a final civil-status certification. That approach allows the administration or the court to correct the real defect without treating the whole application as unreliable.<\/p>\n A British resident who has no French social-security number after Brexit should first determine whether the correct route is French employment, self-employment, an S1 registration or residence-based PUMa cover. The application must then prove identity, regular stay and the relevant period or exception, using the Cerfa S1106 form and a complete civil-status file. A NIA, a NIR, an attestation de droits and a carte Vitale are different stages. The absence of the physical card does not, by itself, answer the question whether the applicant has healthcare rights or can obtain reimbursement.<\/p>\n If the CPAM returns the file, obtain the reason and repair the precise defect. If it issues a refusal, or if a legally relevant silence becomes a rejection, preserve the dates and send the CRA appeal within two months of notification where Article R. 142-1 applies. If the appeal fails, prepare the judicial claim under the social-security litigation rules. The documents and deadlines matter more than the label attached to the problem: \u201cBrexit\u201d, \u201cno number\u201d and \u201cno card\u201d are not substitutes for identifying the statutory route and the evidence that proves it.<\/p>\n Telephone consultation within 48 hours with a lawyer from the firm.<\/p>\n We can review the CPAM refusal, missing-document request, S1 registration or delayed NIR file and identify the next procedural step.<\/p>\nI.
