Switching Health Insurance in Spain Without Waiting Periods: How Sanitas Recognizes Your History

Published on September 1, 202611 minBy Eugenio

If you have been insured for at least one year with another private insurer and you move to Sanitas without a single day’s gap between policies, you don’t start from zero: your insured time is recognized and the waiting periods on medical-network cover are waived. Sanitas’ underwriting rules call this «procedencia de la competencia» — competitor origin — and it is the reason switching insurers in Spain doesn’t mean waiting months again for hospitalization or an MRI. There is an extra rule most expats don’t know: if you come from Bupa or any company in the Bupa group, Sanitas treats your history as its own, with conditions of its own. Timing matters too: most Spanish health policies renew on January 1st and the law requires giving your insurer one month’s notice not to renew, so the real decision window is September to November. This guide covers, with the current underwriting rules in hand, which waiting periods are waived and which are not, what documents you need, and how to line up the dates so you are never uncovered.

Frequently Asked Questions

Common questions

Direct answers, the same we give at the office.

What exactly is Sanitas’ “competitor origin” rule?

It is the official figure in Sanitas’ underwriting rules that recognizes your insurance history when you arrive from another company. If you have been insured for at least one year with another private health insurer operating in Spain and you sign up with Sanitas meeting the requirements, the waiting periods on medical-network cover are reduced: hospitalization, surgery or high-tech diagnostics stop having waits because you already served them with your previous insurer. It is worth understanding what it is not: it isn’t a commercial promotion that comes and goes, but a stable underwriting condition, regulated in writing, with its own requirements and paperwork. It isn’t automatic either: it must be requested and documented at sign-up, not afterwards. At the office we process it every week, especially between October and December, when most of our clients prepare their switch for the January renewal.

I’m coming from Bupa. Is it true my history counts as if I had been with Sanitas?

Yes, and it is one of the most valuable rules for British expats and international clients: Sanitas is part of the Bupa group, and its underwriting rules treat origin from Bupa — or from any company in the Bupa group — as origin from another Sanitas policy, to all effects. The conditions are specific: it applies when you take out a full-coverage product and there is continuity of insurance, the certificate from your Bupa company is accepted in Spanish or in English, and for UK origins the classic “transfer form” is also accepted, keeping the underwriting Bupa did when you first joined. Two details go further than the standard competitor rule: no age limit is applied to the transfer and no age surcharge is charged, and conditions you acquired while insured with Bupa are accepted — only pathologies prior to your original Bupa sign-up can be excluded. Bring your Bupa certificate showing your start and end dates and confirming premiums were paid, and we prepare the switch so your seniority travels with you.

Which waiting periods are waived and which stay even if I switch?

The waiver applies to what the rules call own-provision cover, meaning what you use inside the Sanitas medical network: hospitalization and operations, high-tech diagnostics or therapeutic methods that on a normal sign-up would carry months of waiting. There are two exceptions the rules set out clearly and that you should know before deciding: childbirth and bariatric surgery keep their waiting periods in all cases, whichever insurer you come from. And there is a third nuance almost nobody mentions: if your product includes reimbursement cover with free choice of doctor, the waiting periods on that reimbursement part are not waived; the waiver covers the medical network. Finally, pre-existing conditions are a separate matter from waiting periods: an illness you already had is declared on the health questionnaire just the same, and switching companies doesn’t turn it into covered. If your priority is a pregnancy or a specific condition, tell us first and we will set out exactly what to expect.

What documents will I be asked for to prove my previous insurance?

Two things: proof of your previous policy and proof that it was up to date on payments. For the first, the particular conditions of your current policy work, or a certification from the insurer itself, or even a photocopy of your insured card — with one condition: the names of the insured persons must be clearly stated, whether they have exclusions for any pathology, and the start date on that policy. The card is only admitted if it includes the policy number and your start date as an insured. For the second, you must provide the last receipt paid with your current company. If you request the origin rule for several family members, the paperwork must cover the information of all of them. Our practical advice: ask your current insurer for that certificate before cancelling, because it is far easier to obtain while you are still a client. At the office we review the documentation with you before processing the sign-up so it isn’t rejected over a detail.

Can I let a few weeks pass between cancelling the old policy and starting with Sanitas?

No, and this is the requirement that ruins the most switches: the rules demand that there be no interruption between your leaving date at the previous company and your start date as a Sanitas insured. A single gap of days without cover breaks the continuity of insurance and with it the right to the waiver, even if you have been insured for ten years. The correct way to do it is to lock both dates before moving anything: the Sanitas sign-up is prepared with effect from the day after your current policy expires (the usual pattern is leaving on December 31st and starting January 1st) and only then is the non-renewal notice sent to the other company. That order also protects you in the other direction: you are never left uninsured if something is delayed. It is exactly the coordination we do from the office: we prepare your sign-up with the right effective date and confirm not a single day is left uncovered.

When is the right time to switch insurers in Spain?

Your current policy sets the calendar. The vast majority of health policies in Spain renew on January 1st, and Spain’s Insurance Contract Act establishes that the policyholder can oppose renewal by notifying their insurer at least one month before expiry: in practice, your non-renewal letter must arrive before November 30th. That is why September, October and November are the real decision window: they leave time to compare calmly, request the certificate from your current company, complete the Sanitas health questionnaire and leave the sign-up ready with effect from January 1st, all without rushing and without uncovered days. If your policy expires on another date, the same scheme applies counting one month back from your expiry. And if you already missed this year’s notice period, not everything is necessarily lost: bring us your conditions and we will look at the real margin you have, because each insurer handles out-of-period cancellations differently.

Do my pre-existing conditions get erased when I switch companies?

No, and be wary of anyone who tells you otherwise. The rules are explicit: competitor origin does not mean the removal of pre-existing conditions. When you sign up with Sanitas you always complete the insurance application declaring your previous pathologies, exactly like any other new client. What is recognized from the previous insurance is the time served — that is why the network waiting periods disappear —, not the state of health you arrive with. A declared condition can be accepted normally, accepted with a specific exclusion agreed in writing or, in some cases, with a premium loading; risk assessment decides, and you will always know before signing. What you should never do is omit it: an undeclared pre-existing condition can void the corresponding cover exactly when you need it. Our office recommendation is to declare everything frankly and negotiate the nuance, not hide it: after years of doing this, it is the only approach that works long term.

Does it count if I come from MUFACE, from Spain’s public system, or from a foreign insurer?

These are the cases where the rules do not recognize the origin, and it is better to know before getting your hopes up. It does not apply if you come only from the public healthcare system, because the figure requires history with a private insurer. Nor if you come from a civil-servant mutual society (MUFACE, MUGEJU or ISFAS), nor from a foreign insurer — with one important exception: companies in the Bupa group, Sanitas’ international parent, whose origin is recognized with conditions of its own, something very relevant for Britons and expats arriving in Spain with a Bupa policy. History from a different branch doesn’t count either: coming from a dental policy doesn’t waive waiting periods on a health one. Nor does time on very reduced-coverage products with your previous company. And one detail that surprises people: if you held a Sanitas health policy in the last 6 months, you are not considered a new client and the figure doesn’t apply either. If your case sits on the border of any of these, bring us your paperwork and we will verify it before you move anything.

Do my young children get the waiver too? And what if I was with two companies this past year?

Children have a rule designed for families switching together: a child born during your time with the previous company, even without a full year of seniority, also receives the competitor origin if they were insured there from birth and move to Sanitas together with their parents, provided at least one parent meets the requirements. In other words, the family’s baby doesn’t break the waiver for everyone else, nor miss out on it themselves. As for having passed through more than one insurer in the last 12 months, the rules allow it under a strict condition: the contracts must have followed each other consecutively, with no interruption between one and the next, and you must provide the documentation from every company in the period, not just the last one. Continuity of insurance is the idea that governs everything: as long as the chain hasn’t broken for a single day, your seniority travels with you.

Does the waiver apply to any Sanitas product I take out?

It is designed for full healthcare products, which are also the ones with waiting periods worth waiving: Más Salud and its range, with hospitalization, surgery and high-tech diagnostics inside the medical network — and in the case of Bupa origins, the rules state expressly that it applies when taking out a full-coverage product, not a limited one. Some budget products have their own access rules instead: Sanitas Accede, for example, is a new-customer product designed for people who haven’t been recent Sanitas clients, and its big advantage is a different one: it is born directly with no waiting periods for everyone, wherever you come from. And on products with reimbursement, remember the usual nuance: the medical-network part benefits from the waiver, the reimbursement part keeps its timelines. That is why our recommendation is not to choose the product and the waiver separately: tell us which company you come from, which product you had and what you need covered without waiting, and we will prepare the combination with the exact conditions in writing, together with your profile’s real price in this site’s calculator.
