Spain's Healthcare System: How the SNS Works

Spaniards know how to enjoy life, and they also have one of the longest life expectancies in the world. The Mediterranean diet, healthy lifestyles and the healthcare system are often cited as key reasons for this.

The Spain healthcare system is ranked among the best in the world, and the good news is that if you live or work in Spain, you can also access it. Whether that access is through the public healthcare system or private insurance depends on a variety of factors.

Keep reading to learn how the Spanish healthcare system works and how expats in Spain can access it.

What is Spain's Sistema Nacional de Salud (SNS)? 

Spain's public healthcare system is officially known as the Sistema Nacional de Salud (SNS), or National Health System. Although the system operates within a national framework, healthcare services are managed independently by Spain's 17 autonomous communities.

This decentralized approach allows each region to organize and deliver healthcare services according to the needs of its local population, so access procedures and services may vary slightly depending on where you live.

Spain is internationally recognized for its high-quality public healthcare system, which provides extensive medical coverage to eligible residents. According to the OECD's Health at a Glance 2025 report, Spain has a life expectancy of 84 years, almost three years above the OECD average. The country also performs better than the OECD average in several important healthcare indicators, including preventable and treatable mortality.

What does the SNS cover, and what does it cost?

The SNS provides comprehensive medical coverage, including primary care visits, specialist appointments, hospital treatment and emergency care. Most services are free at the point of use, meaning patients do not pay when they receive treatment.

However, some services involve additional costs. Prescription medications generally require a copayment of 10% to 60% of the price, depending on income, employment or retirement status, and other eligibility criteria. Even so, Spain's healthcare system remains highly accessible and affordable compared to many other countries.

Who is eligible for public healthcare in Spain?

Access to Spain's public healthcare system depends on your residency status, employment situation and individual circumstances. Spanish citizens, eligible legal residents, employees, self-employed workers, pensioners and certain family members can generally access publicly funded healthcare. EU citizens may also qualify through European healthcare agreements.

Check with the authorities in the autonomous community where you live and, if necessary, speak to your consulate or embassy.

Throughout the whole process, your NIE (Número de Identidad de Extranjero), or Foreigner Identification Number, is extremely important. If you haven't yet read our post on how to get a NIE, check it out now.

However, having a NIE does not automatically guarantee access to public healthcare: your eligibility must be established through the appropriate authorities. We know bureaucracy can be a pain, but you're almost there!

Steps for getting a health card

1. 1. If you're already living in Spain or have an agreement in place for a house or apartment, one of the first steps is registering your address with your local town hall (empadronamiento).
2. 2. Next, if you plan to work in Spain, you'll generally need to register with Social Security and obtain a Social Security number.
3. 3. Once your entitlement to public healthcare has been confirmed, you can apply for a health card (tarjeta sanitaria) through your regional health service, usually at your local health center.
4. 4. Once you receive your health card, you can book appointments with your assigned primary care doctor.

Keep in mind that specialist consultations and certain medical treatments generally require a referral from your primary care doctor, except in emergencies. Private hospitals and clinics are not automatically covered by the SNS.

In an emergency, call 112 free of charge from any mobile phone or landline. In most tourist areas, the service is available in English, French and German.

Public vs. private healthcare in Spain: what's the difference?

The main difference between public and private healthcare in Spain is waiting times. Public healthcare is excellent, but it can sometimes be slow. One of the most talked-about benefits of private health insurance is faster treatment, especially for non-emergency procedures.

Another great benefit of private health insurance is being able to choose your preferred doctor and medical team, and to receive care from doctors who offer services in your language. After all, not everyone who moves to Spain speaks perfect Spanish when they arrive!

Here are some situations in which private healthcare may be recommended:

• You have just arrived in Spain and are not yet a resident or paying Social Security contributions. In this case, it's best to have your own private health insurance to avoid paying the full cost of your healthcare.
• You are an EU citizen, but your European Health Insurance Card (EHIC) is only valid if you are in Spain on a temporary visit or studying. If you have decided to become a long-term resident, you should take out private health insurance until your paperwork is sorted.
• You're from outside the EU and are only visiting Spain. Spain has bilateral agreements with some countries that allow visitors (non-residents) to receive free emergency medical treatment. Whether this applies depends on your country, so contact your embassy to check whether your home country has an agreement with Spain.

When is private health insurance mandatory in Spain?

While Spain's public healthcare system provides extensive coverage, private health insurance is mandatory for certain visa and residency applications, particularly for non-EU citizens who are not eligible for public healthcare. In these cases, applicants must show that they have adequate medical coverage throughout their stay in Spain.

Private health insurance is commonly required for:

• Non-lucrative visas: applicants must have comprehensive health insurance that meets Spanish residency requirements.
• Digital nomad visas: private insurance is required if applicants cannot demonstrate qualifying public healthcare or Social Security coverage.
• Other residency applications: certain applicants, including students, may need private health insurance depending on their visa type and circumstances.
• Provide comprehensive coverage with no copayments or deductibles.
• Have no waiting periods or coverage limits for required medical services.
• Be issued by an insurance company authorized to operate in Spain.
• Remain valid for the required period of residence.
• If you are looking for comprehensive healthcare coverage and do not want to rely on Social Security, we recommend an insurance policy with hospitalization coverage.
• If you only use healthcare occasionally, we recommend an insurance policy without hospitalization coverage, and using Social Security when hospitalization is necessary.

For visa applications that require private coverage, the policy generally must:

Standard travel insurance is generally not sufficient for these residency applications.
