When you first move to Spain, the biggest worry is getting sick, especially with a major illness. I’d always heard that Spanish public healthcare is free, but I was never clear on the details, especially when it comes to ‘big-ticket items’ like hospitalization and surgery. A friend of mine recently went through a minor surgery, and I was with them the whole way. I’ve finally figured out the ins and outs of how both public and private insurance handle major medical expenses. I’m sharing this guide to hopefully help others who need it.
The Public Healthcare System
If you’re registered with social security, congratulations—you’ll barely have to pay anything for major medical treatments in Spain. ‘Major treatments’ here refer to situations requiring hospitalization, surgery, complex tests, etc.
The process generally looks like this:
- GP Referral: For any health issue, your first stop is your local health center to see your family doctor (GP). If they can’t handle it, they will refer you to a specialist.
- Specialist Diagnosis and Treatment: The specialist will arrange for various tests. If they confirm that surgery or hospitalization is needed, they will schedule the hospital and bed for you directly within the system.
- Hospitalization and Surgery: From admission, surgery, medication, and nursing care to post-discharge check-ups, all costs incurred within a public hospital are completely free! You just need to show your health card (tarjeta sanitaria). You won’t even see a bill, let alone go through a ‘reimbursement’ process like with Spanish public healthcare, because you never pay upfront.
The biggest drawback of the public system is that it’s slow. The wait from seeing a GP to getting an appointment with a specialist, and then waiting for surgery, can take several months or even over a year. Unless it’s a critical emergency, you’ll need a lot of patience.

Private Health Insurance
Many people buy private health insurance to avoid the long waits of the public system. My friend used their private plan this time. For major medical issues, private insurance typically works in one of two ways, depending on your policy type.
Comparison of Common Models:
| Insurance Type | Reimbursement Method | Pros | Cons |
| Cuadro Médico (Network Plan) | You go directly to hospitals and clinics within the insurer’s network, present your insurance card, and generally pay nothing out of pocket. | Convenient and hassle-free; no need to pay large sums upfront. | Limited to doctors and hospitals within the designated network. |
| Reembolso (Reimbursement Plan) | You must pay the full cost upfront and then submit the invoices to the insurance company for reimbursement. The reimbursement rate is typically between 80% and 100%. | Complete freedom to choose any doctor or hospital, allowing access to the best specialists in all of Spain. | Requires having sufficient funds to pay upfront, and the reimbursement process takes time. |
My friend’s surgery was done under a Reembolso plan. The total cost for the surgery and hospital stay was nearly €10,000. He paid it with his credit card, then gathered all the invoices and doctor’s reports and submitted a claim through the insurance company’s app. About three weeks later, the insurer transferred 90% of the cost back to his account. Although paying that much upfront was a bit painful, being able to quickly get surgery with the best doctor made it feel completely worth it.
If you’re generally healthy and not in a hurry, the public system is perfectly adequate and saves money. However, if you value efficiency, want more choices, or worry about unexpected situations, buying a private insurance plan is the best investment for ‘buying peace of mind.’ I hope everyone stays healthy in Spain and never needs to use this guide!
