When I first came to Spain, I needed insurance to apply for my residency, so I just grabbed the cheapest plan I could find, thinking I’d never use it. Well, a minor sports injury last year taught me that the right insurance can truly make or break your quality of life in a critical moment. After dealing with the major players—Adeslas, Asisa, and Sanitas—I’ve learned a thing or two. Today, I’m sharing my insights to help anyone who’s struggling to choose.
First Impressions of the Three Major Companies
These three are the giants of the Spanish insurance market, with extensive coverage and a large network of private hospitals and clinics. In a nutshell:
- Adeslas: Seems to have the largest market share; many of my local Spanish friends use them. They have numerous branches and a comprehensive network of medical centers. Their pricing is in the mid-to-high range.
- Asisa: Strong in terms of doctor resources, especially specialists. A friend mentioned they have an edge in treating certain specific conditions. The price is similar to Adeslas, sometimes slightly cheaper.
- Sanitas: The best in terms of internationalization. Many of their apps and services have English interfaces, making them very friendly for those who aren’t fluent in Spanish. The service experience feels modern, but they are also typically the most expensive.

Personal Experience Comparison
Last year, I injured my knee playing football and needed to see a specialist and get physical therapy. I have a policy with Adeslas, and the process was quite smooth overall—booking a specialist and getting an MRI was quick. However, the authorization for the subsequent physical therapy took a few days. A friend of mine with Sanitas, in a similar situation (he’s actually in a field related to healthcare jobs in Spain), said his physical therapy was approved instantly with just a few taps on the app. You can really feel the convenience, but of course, his premium is significantly higher than mine. Another friend with Asisa mentioned that it’s easier to get appointments with renowned specialists through their insurance, though I’m not sure if that’s a common experience.
Based on my own and my friends’ experiences, here’s a simple comparison table for your reference:
| Item | Adeslas | Asisa | Sanitas |
| Price | Moderate | Moderate | High |
| Network Coverage | Extensive | Extensive | Extensive |
| App Experience | Average | Good | Excellent |
| Claims/Authorization Speed | Moderate | Moderate | Fast |
| Language Support | Mainly Spanish | Mainly Spanish | Good multilingual support |
| Special Features | Market leader, reliable | Specialist resources | Modern and international service |
There’s no absolute best, only what’s most suitable for you. If you’re looking for cost-effective Spanish health insurance and don’t need a top-tier app experience, Adeslas and Asisa are both solid choices. If, for your Spanish health insurance, you have a larger budget or aren’t fluent in Spanish and want a smoother service experience, then spending a bit more on Sanitas is definitely worth it. Before buying any insurance, be sure to read the terms carefully, especially the part about Copago (co-payment). Whether a plan is ‘sin copago’ (without co-payment) or ‘con copago’ (with co-payment) makes a huge difference. I hope my experience helps, and I welcome friends who have used other insurance companies to share their thoughts too!
