PB4 Health Agreement: How Brazilians Access the SNS in Portugal

Healthcare access is one of the most important practical questions for any Brazilian considering a move to Portugal, particularly for retirees and families. The answer is better than most people expect — and requires one specific document that most people have never heard of until they need it: the PB4.

What the PB4 Is

The PB4 (officially, the "Certificado de Direito à Assistência Médica") is a certificate issued by the Brazilian Ministry of Health that proves you are covered by Brazil's social security system (INSS or equivalent). It is the key document that unlocks access to Portugal's public health system (SNS — Serviço Nacional de Saúde) under the bilateral health agreement between Brazil and Portugal.

The agreement, which has been in place for decades, exists because both countries are members of the CPLP and share a recognition that their citizens may move between the two countries for extended periods. Portugal agreed to extend SNS access to Brazilian residents who hold the PB4, and Brazil extends reciprocal access to Portuguese residents in Brazil.

The PB4 is not exclusively for retirees. It is available to anyone who contributes to or receives benefits from the Brazilian social security system — which includes most Brazilian workers who have ever paid INSS contributions, regardless of whether they are currently receiving a pension.

How to Get the PB4

The PB4 is issued online through the Brazilian government portal (gov.br) and is free of charge. The process is straightforward:

1. Access the PB4 service at gov.br (search "PB4" or "Certificado de Direito à Assistência Médica")
2. Log in with your CPF and GOV.BR account credentials
3. Select Portugal as the destination country
4. The certificate is generated immediately as a PDF

It is valid for one year and renewable. Print it before you leave Brazil, and keep a digital copy accessible on your phone. You will present it at the health center in Portugal when you register for your SNS patient number.

One practical note: the PB4 proves your connection to the Brazilian system. You do not need to be actively receiving INSS benefits — you simply need to have contributed to the system. If you have never worked formally in Brazil or made INSS contributions, the PB4 may not be available to you, in which case private health insurance is the alternative for the D7 visa application.

Registering with the SNS: Getting Your Número de Utente

The PB4 by itself does not automatically enroll you in the SNS. You need to register at your local health center (centro de saúde) in Portugal to obtain a Número de Utente — your patient identification number.

To register, bring:

• Valid passport
• PB4 certificate
• Proof of Portuguese address (the Atestado de Residência from the Junta de Freguesia, or your AT-registered lease contract)

The Número de Utente is issued on the spot at most centers, or within a few days. With it, you have access to:

• General practice (médico de família) consultations
• Public hospital emergency care
• Specialty referrals
• Vaccinations and preventive care
• Prescription medications at subsidized prices

What SNS Access Actually Costs

Portugal's SNS is not completely free — it charges "taxas moderadoras" (co-payments) for most services. In 2026, approximate rates are:

• General practice consultation: €5.00
• Specialist consultation with referral: €7.50
• Emergency room visit (non-urgent): €20.00
• Emergency room visit (urgent): €14.00

These amounts are symbolic for most purposes. Certain groups are exempt from co-payments entirely: people below a defined income threshold, pregnant women, children under 18, and people with chronic conditions under certain criteria.

For regular prescription medications, subsidized prices range from 0% to 90% of the cost, depending on the medication's therapeutic classification and your income level.

The Brazil to Portugal D7/D8 Visa Guide includes the complete healthcare registration sequence — PB4 application, SNS registration, and how to navigate the médico de família assignment process — as part of the post-arrival settlement checklist.

Private Health Insurance: When You Still Need It

The D7 and D8 visa applications require proof of health insurance coverage as a condition of approval. For D7 applicants, this is a standard requirement. The PB4 is useful for SNS access once you are in Portugal, but the consulate still wants to see formal insurance coverage for the visa issuance stage.

Some applicants present private health insurance for the visa and then switch to SNS-only access after arriving. Others maintain private coverage alongside SNS access, particularly for dental and optical care (neither of which is covered by the SNS) and for faster specialist access without waiting for referrals.

Private health insurance in Portugal for a healthy adult runs approximately €30–€80 per month depending on the provider and coverage level. Médis, Multicare, and Fidelidade are the main providers. Some Brazilian companies also offer coverage that is valid in Portugal, which can simplify the initial period before local insurance is set up.

The D7 Visa and Health Insurance Proof

For the consulate, proof of health insurance is a standard checklist item. Acceptable documentation:

• A policy certificate from a recognized insurer showing coverage during the requested visa period
• A European Health Insurance Card equivalent, if applicable
• An official letter from a health system confirming enrollment (e.g., a SNS registration letter if you have already obtained one — possible for Brazilians who have visited Portugal previously)

The policy must cover the full period of the requested visa. A policy that expires mid-visa will trigger a document deficiency notice.

Healthcare for Children of Brazilian Residents

Children accompanying Brazilian residents have full SNS access under the same conditions as their parents, once properly registered. The registration process is the same: Número de Utente obtained at the local health center with a passport, proof of address, and the parent's PB4 (the child's own PB4 is issued separately if the child has contributed to INSS — generally required only if the child is old enough to have worked).

School vaccinations in Portugal follow the National Vaccination Program (PNV). The centro de saúde handles these automatically once the child is registered. Brazilian vaccination records are generally accepted as equivalent for the childhood vaccines that overlap, with any gaps filled by the Portuguese program.

Long-Term Healthcare Planning for D7 Retirees

For Brazilian retirees on the D7 visa, healthcare access is one of the strongest arguments for Portugal over other residency destinations. The combination of SNS access via PB4, low co-payments, and Portugal's generally high standard of public healthcare makes the health side of the move significantly better than what many Brazilian cities offer in the public system.

The practical limitation is the médico de família (family doctor) assignment, which can take weeks or months depending on the health center's capacity. During that period, you can still access emergency care and walk-in appointments at the centro de saúde — you simply do not have a designated GP. For non-urgent conditions, patience is required until the assignment is made.
