Requesting the Cartão Europeu de Seguro de Doença (European Health Insurance Card) in Portugal in 2026 — A Practical Guide to the Segurança Social Issuance, the Three-Year Validity and Reciprocal SNS Cover Across the EU/EEA/Switzerland

If you live in Portugal and ever leave the country for a short trip inside Europe — on holiday, on business, on Erasmus, or to visit family — the single document that protects you against catastrophic medical bills while you are away is the Cartão Europeu de Seguro de Doença (European Health Insurance Card, CESD or EHIC). The card is issued by the Portuguese Segurança Social (Social Security) free of charge, runs for three years, and gives you access to the public-sector healthcare system of any EU Member State, plus Iceland, Liechtenstein, Norway, Switzerland and (under the post-Brexit reciprocity arrangement) the United Kingdom, on the same terms as a local resident. This 2026 guide walks through the eligibility frame, the online issuance flow, what the card covers, what it does not cover, the Certificado Provisório de Substituição (Provisional Replacement Certificate) backstop and the practicalities of using the card abroad.

What the card is, legally

The CESD is the Portuguese-issued instance of the EU-wide European Health Insurance Card, the document that operationalises Articles 17 to 35 of Regulamento (CE) n.º 883/2004 (the EU regulation on the coordination of social-security systems) and Regulamento (CE) n.º 987/2009 (the implementing regulation). The card is not a private health-insurance policy. It is a portable certificate that proves to a public hospital or health centre in another participating state that you are entitled to medically necessary public-sector care while you are temporarily staying there, on the same conditions and at the same cost as a local resident of that state. The card is honoured in all 27 EU Member States; Iceland, Liechtenstein and Norway under the EEA agreement; Switzerland under the EU-Switzerland bilateral; and the United Kingdom under the EU-UK Withdrawal Agreement and the subsequent reciprocity tap that replaced the EHIC with the UK-issued GHIC and the EU-issued EHIC for cross-border use after 1 January 2021.

Who is eligible

The Segurança Social issues the CESD to anyone who is covered under a Portuguese social-security regime, including the dependants of those covered persons. In practice this means:

• Employed workers (trabalhadores por conta de outrem) under the general regime;
• Self-employed workers (trabalhadores independentes) under the Recibos Verdes / Categoria B independent-worker regime;
• Pensioners drawing a Pensão de Velhice, Pensão de Invalidez or Pensão de Sobrevivência (old-age, disability or survivors pension);
• Spouses, civil partners (uniões de facto) and children registered as familiares (dependants) of the above;
• Beneficiaries of the public and private health subsystems — ADSE (the civil-service health subsystem), SAD-PSP (police), SAD-GNR (gendarmerie), ADM (armed forces) — with the card issued under the same Segurança Social rail;
• SNS users without separate social-security coverage or subsystem coverage, who can request the card directly from Segurança Social as long as they hold a Número de Utente (SNS user number) and a NISS (Número de Identificação de Segurança Social, Social Security Identification Number).

Each household member, including each child and each dependant, needs their own CESD. There is no family card.

What you need before requesting

You need four pieces of information to order a CESD: the cardholder's NISS, the cardholder's SNS user number (número de utente), a valid residential address in Portugal and a verified e-mail address (the email is required if you take the Segurança Social Direta online route, which is by far the fastest path). For children and dependants you also need their NISS and SNS user number under the household's contributory record.

The Segurança Social Direta online flow

The Segurança Social Direta (SSD) portal at seg-social.pt is the recommended channel and the one that delivers the card fastest. The flow is:

1. Sign in to Segurança Social Direta with your NISS and password, or with the Chave Móvel Digital (Digital Mobile Key) authentication track if you have activated it via the AMA Loja-de-Cidadão or the AMA online flow.
2. Navigate Cidadão → Saúde → Cartão Europeu de Seguro de Doença → Pedir cartão.
3. Confirm your morada (address) and the Número de Utente that prefills from the integrated SNS record.
4. If you are requesting the card for a dependant, switch to the dependant's profile (the SSD lets a parent or spouse manage household members' records) and submit a separate request for each one.
5. Submit. The card is sent free of charge to the address on file within approximately 7 working days, and a Certificado Provisório de Substituição (Provisional Replacement Certificate, CPS) is e-mailed to you in PDF format if you flag the option — the CPS gives you the same rights as the card while you wait for the plastic to arrive.

The walk-in alternative routes are the Segurança Social local atendimento desks (book the appointment via the SSD portal) and the Loja de Cidadão multifunctional desks — both take longer than the online flow and there is no fee in either case.

What the card covers, exactly

The CESD covers medically necessary public-sector healthcare during temporary stays in another participating state — defined as care that cannot wait until the cardholder returns to Portugal. The benchmark covers emergency care, the management of chronic conditions (including dialysis, oxygen therapy, chemotherapy, insulin), maternity care, vaccinations needed because of an exposure event and the prescriptions associated with the above. The care is delivered on the same conditions and at the same cost as a local resident of the host country — meaning that if a local resident pays a co-payment, the cardholder pays it; if a local resident does not, the cardholder does not.

What the card does not cover

The card does not cover:

• Private-sector care of any kind — only public hospitals and contracted-public providers honour the card. In Portugal the equivalent is the SNS hospital and health-centre network; in Spain, the public health-service hospitals of the SNS (Sistema Nacional de Salud); in France, the public hôpitaux and the conventionné private clinics that bill the Assurance Maladie directly; and so on.
• Planned treatment abroad — if the cardholder travels to another state specifically to receive a particular treatment, the CESD does not apply. Planned care needs the S2 portable document (formerly the E112) issued by Segurança Social or the Cross-Border Healthcare Directive 2011/24/UE reimbursement route filed through Direcção-Geral da Saúde (DGS).
• Repatriation costs — if you fall seriously ill or die abroad, repatriation back to Portugal is not covered. This is the gap that private travel insurance fills, and it is the single biggest reason the Direção-Geral dos Assuntos Consulares e das Comunidades Portuguesas (DGACCP) advises travellers to layer private travel insurance on top of the CESD.
• Holders of a permanent residence permit in a non-EU country (other than Switzerland and the UK) when travelling outside Portugal.

The Certificado Provisório de Substituição (CPS) backstop

If you need to travel before the card arrives, or if you have lost the card while abroad, the Certificado Provisório de Substituição (CPS) substitutes for the physical CESD. The CPS is issued by Segurança Social on the same online or counter flow and is delivered electronically in PDF format — you can print it or carry it on your phone and present it at the hospital alongside your passport or Cartão de Cidadão. The CPS has the same legal force as the physical card and is the document the hospital should accept when admitting you. It is also the document the relevant foreign social-security institution will use to bill Segurança Social directly under the EESSI (Electronic Exchange of Social Security Information) cross-border settlement system that replaced paper-based billing in 2019.

Validity and renewal

The card runs for three years from the date of issue, with the expiry date stamped on the front of the plastic. Renewal is done on exactly the same online flow as the initial issuance — sign in to Segurança Social Direta in the last 30 days before the expiry date and click renovar. The renewal is free. There is no automatic renewal, so you need to remember to file the renewal request before the card expires. If you let it lapse, you simply file a new request — the card will be reissued on the standard 7-working-day clock.

Using the card abroad in practice

When you arrive at a public hospital or health centre in the host country, present the CESD (or the CPS) together with a government-issued ID. The hospital admits you under the same regime as a local resident, performs the medically necessary treatment, and bills the host-country social-security institution. That institution then settles the cross-border invoice with Segurança Social via EESSI — you do not pay up front for the care itself, only for whatever co-payment a local resident would pay. If the hospital nonetheless asks you to pay up front (which happens occasionally in tourist-heavy hospitals in Spain, Italy and Greece), keep the original receipts, the discharge summary and the diagnosis code, and file a reimbursement request via the Centro Distrital de Segurança Social on your return.

Lost or stolen card

If the card is lost or stolen, request a CPS via SSD or by phoning the Segurança Social hotline at 300 502 502 to get one issued by e-mail. The CPS substitutes the lost card immediately. Once you are back in Portugal, file a request for a replacement card via the same online flow — it is free.

The post-Brexit UK arrangement

Since 1 January 2021, the EHIC issued by Portugal continues to be accepted in the United Kingdom for medically necessary public-sector care under the EU-UK reciprocity arrangement that survived Brexit and was confirmed in the 2020 EU-UK Trade and Cooperation Agreement. Practically: a Portuguese resident with a valid CESD will be admitted at NHS hospitals and GP surgeries on the same terms as a UK resident. Note that the UK has since launched its own GHIC (Global Health Insurance Card) which the NHS issues to UK residents for use inside the EU — the GHIC is the UK's equivalent of the CESD and the two cards operate as mirrors of each other.

Common pitfalls

• Trying to use the CESD at a private clinic abroad. It will not work — the card only covers public-sector and contracted-public providers.
• Travelling on an expired CESD. The expiry date on the front of the card is hard — an expired card is not honoured at the hospital. Renew it before you travel.
• Skipping the CPS step when the card has not arrived in time for the trip. The CPS takes minutes to issue via SSD and gives full cover during the gap.
• Confusing the CESD with private travel insurance. The CESD does not cover repatriation, private hospital stays, lost luggage or trip cancellations — layer private travel insurance on top for those.
• Forgetting to request a separate card for each dependant. Each family member needs an individually-numbered card; the children's cards are not bundled with the parents'.

Bottom line

The Cartão Europeu de Seguro de Doença is free, takes minutes to request via Segurança Social Direta, arrives within a working week and runs for three years. If you live in Portugal and plan to travel anywhere inside the EU, EEA, Switzerland or the UK over the summer, request the card now — and request one for every dependant in the household. The CPS gives you immediate cover while the plastic is being printed. The card does not replace private travel insurance, but it materially closes the catastrophic-medical-bill gap, anchoring you to the host country's public hospital network on the same terms as a local resident. With the IPMA aviso-amarelo heat-wave window opening on 21-22 June and the summer holiday calendar pushing Portuguese residents into Spain, France, Italy, Greece and the UK across July and August, the card is the single most overlooked piece of pre-travel paperwork in Portugal's outbound-tourism stack.
