How Underwriting Works
Spanish private health insurers are not required to accept all applicants regardless of health. Before cover starts, each person completes a health questionnaire (cuestionario de salud), and the insurer uses it to decide whether and on what terms to offer cover.
You must declare everything the questionnaire asks about that you know of. If something is left out, the insurer can cancel the policy within a month of finding out; if a claim arises first, payment can be reduced in proportion — or refused where the omission was deliberate or grossly negligent.

Possible Outcomes
- Accepted on standard terms — the condition is covered like anything else.
- Accepted with an exclusion — the policy runs, but treatment for that condition isn’t covered.
- Accepted at a higher premium, where the insurer offers that.
- Declined — acceptance is never guaranteed.
Outside the visa context, some policies cover a condition only after a waiting period. Policies used for a visa must have no waiting periods, so for a visa the usual outcomes are acceptance, an exclusion for the specific condition, or a higher premium.
Impact on Visa Applications
For Spanish visa purposes, you need health insurance that covers you during your stay in Spain. A policy with pre-existing condition exclusions can still be valid for visa purposes — the consulate is checking that you have valid health coverage, not that every possible condition is covered. However, the exclusion means you’d pay out of pocket for treatment of the excluded condition. Our guide to health insurance for a Spanish visa sets out what the certificate must show for each visa.
If you have significant healthcare needs related to a pre-existing condition, factor in the likely out-of-pocket costs when planning your move.
Older Applicants
Age and medical history are assessed together. A plan for over-60s with no health questionnaire exists, but it doesn’t include hospitalisation or surgery and isn’t accepted for the NLV or DNV. See health insurance for retirees and which plan suits you.
Switching With a Condition
A new insurer assesses your health again and may exclude a condition your current policy covers. Keep your current policy until the new one has accepted you, and start the new one the day after the old one ends. See switching health insurance in Spain.
Public Healthcare as a Supplement
If you’re entitled to public healthcare in Spain (via social security contributions for workers, or via the S1 form for UK pensioners), the public system does not exclude pre-existing conditions. This can provide a safety net alongside your private policy.
