Can I switch health insurer in Spain without new waiting periods?
Yes: if you've had full-cover health insurance with another company in Spain for at least a year, Sanitas removes the waiting periods on your new policy, except childbirth and bariatric surgery, once you provide your policy schedule (or a card showing your start date) and proof of your latest premium payment.
The offer applies to policies held with another insurer in Spain. If you're on an international plan bought abroad, send it to me and I'll check whether it counts before you cancel anything. With less than a year, or a dental-only or consultations-only plan, the normal waiting periods apply: 3, 6 or 8 months depending on the service, and others for some complex treatments.
