Some healthcare routes in Spain work through an approved medical directory rather than through a completely open “go anywhere” model. That means doctors, clinics, hospitals, and services are accessed through the network linked to the product.
This does not necessarily make the system difficult. In fact, it can make it more structured. The important habit is to confirm that the professional or centre is approved for the specific service you need before arranging non-urgent treatment.
For urgent situations, the emergency route should still be followed. For routine access, provider confirmation is often the key step.
