Guide to Medical Questions and Underwriting for NLV Health Insurance

Of all the parts of an NLV application, the medical questions cause the most needless anxiety. People imagine an interrogation, or assume that mentioning anything at all will sink their application. The reality is far more ordinary: insurers ask some health questions, you answer them accurately, and in most cases cover is issued without drama. This guide walks through the whole process so you know what to expect and why honesty is genuinely in your interest.

1. Why Spanish insurers ask

Private medical cover is priced and accepted based on risk, so insurers ask about your health before they issue a policy. This is normal the world over — it is not a hurdle designed to catch you out. For the NLV there is an added benefit: because the questions make sure the cover fits your situation, you end up with a policy that will genuinely look after you if you need it. See the core medical questionnaire page.

It also helps to remember what the insurer is actually trying to do. They are not looking for a reason to say no; they are trying to understand your situation well enough to set fair, sustainable terms for a policy that may run for a year or more and then renew. The questions are the tool they use to do that. Answered properly, they work in your favour — they steer your application towards cover that is priced correctly and that will not be unpicked later. A policy issued on a full, accurate picture is a policy you can rely on, which is the whole point of buying it for a year of life in Spain.

2. What the questionnaire asks

A typical questionnaire covers current and past medical conditions, any medication you take, recent surgery or hospital admissions, and sometimes height and weight and a few lifestyle questions. The questions are usually straightforward. The single most important thing is to answer them accurately rather than guessing, rounding or leaving things out because they seem minor. If you are not sure whether something counts, declare it and let the insurer decide — that is always the safer choice.

Most questionnaires are shorter than people expect. Many are a single form of tick-box questions with room to add a short note where you answer "yes" — for instance, the name of a medicine and the condition it treats, or the year and outcome of a past procedure. You are not expected to write a medical essay or to diagnose yourself; a plain, factual note is exactly what the insurer wants. If a question is unclear, it is far better to add a sentence of context than to guess at what is being asked. Where the form leaves space for detail, using it tends to help rather than hinder, because it lets the insurer see the full, settled picture rather than having to ask again.

3. Your declarations are confidential

Understandably, one of the first worries people have is where their medical information goes and who sees it. The reassuring general position is that the health details you give for an application are treated as private, sensitive information. They are used for one purpose — to assess your application and arrange suitable cover — and handled with the care that health data warrants. This is not information shared casually or used to judge you as a person; it is a working input to a technical process.

In practice that means your declarations are seen by the people who need them to do the job: the specialist helping you place cover, and the insurer's underwriting team who assess the application. The purpose is narrow and the handling is discreet. If it helps to think of it plainly, the medical questionnaire is a professional document exchanged in confidence, not something on public view. This is a general description of how sensitive information is treated rather than a specific legal guarantee, and if you have questions about data handling you are always welcome to ask before you share anything. Knowing the information stays within that professional circle is often enough to make the disclosure feel a good deal less exposing than people fear.

4. Medication

Regular medication is one of the most common things applicants declare, and usually it just needs to be listed — the name of the medicine and what it is for. Declaring it lets the insurer assess it properly, and in many cases it has no dramatic effect on cover at all. What causes problems is the opposite: leaving medication off the form. See medication and NLV insurance.

It is worth saying that long-term, stable medication is routine to insurers. Millions of otherwise healthy people take something daily — for blood pressure, cholesterol, thyroid function, an under-active or over-active gland, or a settled condition kept well under control — and underwriters see these every day. A medicine you have taken steadily for years, with your condition monitored and stable, is a very different picture from something new and unresolved, and it is usually read that way. Listing what you take, why, and roughly how long you have been on it gives the insurer everything needed to assess it calmly.

5. Operations and hospital treatment

Previous surgery or a hospital admission is worth flagging, along with roughly when it happened and whether any treatment is still ongoing. Historic, fully-resolved procedures are often uneventful for underwriting; recent or ongoing ones may prompt a few follow-up questions so the insurer understands the current picture. Being upfront here saves time later. See hospital treatment.

6. Pre-existing conditions

A pre-existing condition is simply something you have before the policy starts. These are assessed during underwriting, and how they are handled depends on the condition and the insurer — acceptance as standard, acceptance with specific terms, or occasionally a decline. Raising them early is the most useful thing you can do, because it lets your application go to the insurer most likely to assess it well rather than being turned away by one that would not. See pre-existing conditions.

7. Conditions that are often handled routinely

It helps to know that a great many everyday medical situations are, in general, handled without difficulty. This is not a promise about any individual case — every outcome depends on the specific condition, the insurer and the person — but the broad pattern is reassuring. Well-managed, stable conditions that are kept in check with regular medication and monitoring are familiar territory for underwriters, as are historic procedures that have fully resolved and left no ongoing treatment. Common examples that are frequently accepted include stable blood pressure or cholesterol managed with long-term medication, a settled thyroid condition, a joint or hernia repair years in the past, or a routine procedure that healed and needs no follow-up.

The reason these tend to be straightforward is that they present a clear, settled picture: the insurer can see what the situation is, that it is stable, and how it is managed. What matters is that the picture is complete and accurate, which is why the guidance is always the same — declare it plainly and let the assessment happen. None of this guarantees a particular result, and we would never pretend otherwise; but it is fair to say that the fear people carry is usually heavier than the reality. See pre-existing conditions and medication and NLV insurance for how each is typically approached.

8. BMI and weight

Some insurers ask for height and weight. It is one factor among many, rarely a decisive one on its own, and it is best answered accurately. There is no benefit to adjusting the numbers — the aim is a policy that reflects reality. More on this at BMI and weight.

9. Older applicants

Age affects availability, underwriting and price more than it affects the NLV requirements themselves. Applicants over 60, 65 and 70 should start early, because options can be narrower and take a little longer to arrange — not because cover is unavailable. Plenty of older applicants and retirees are insured for the NLV every year; the key is simply to give yourself time. See retirees and over-60s, the age-band pages for over 65 and over 70, and age limits.

10. Children and family applications

Each applicant is assessed individually, including children, though children's medical questions are usually light. When a family applies, everyone completes their part of the medical declaration and everyone needs to be covered — send the whole household's details together so they can be quoted properly in one go. Our couples and families guide covers the household side, and the core pages are families and children.

11. What underwriting means

Underwriting is simply the insurer's process of reviewing your answers and deciding the terms. It is not a judgement on you — it is a technical assessment. A quote given before underwriting can change once the medical picture is seen, which is exactly why you should disclose everything up front rather than after a figure has been quoted. See underwriting.

12. Possible outcomes

There are broadly three outcomes. The most common is accepted as standard — cover on normal terms. Next is accepted with specific terms — for example a particular condition handled in a defined way, while everything else is covered normally. Least common is declined, where a particular insurer decides it cannot offer cover. A decline from one insurer is not the end of the road, as a later section explains.

13. What "accepted with specific terms" looks like

The phrase "accepted with specific terms" sounds more alarming than it is, so it is worth demystifying. In plain language it means the insurer is happy to offer you a policy, and has simply defined how one particular part of your history is dealt with, while everything else is covered in the normal way. It is an acceptance, not a refusal — the door is open, with a note attached about one room in the house.

In practice the "specific term" is usually a defined, written condition that relates only to the matter you declared. Everything unrelated to it is covered on standard terms, exactly as it would be for anyone else. This is a routine way for insurers to say yes to a wide range of situations that might otherwise be harder to place: rather than turning an application away, they offer cover with the one area handled on clearly stated terms. The important thing is that the terms are set out in writing, so you can read exactly what they mean before you decide to proceed, and ask about anything that is unclear. Seen that way, it is far less daunting than the phrase first suggests — it is the mechanism that lets many people get covered rather than declined. You can read more about how this fits into the assessment on the underwriting page.

14. What if declined

A decline by one insurer does not always mean no cover is available anywhere — another insurer may assess the same situation differently, which is precisely where specialist help earns its keep. If it happens, we can look at the alternatives with you rather than leaving you to start from scratch. See declined and rejected policies.

It is worth understanding why this happens. Insurers do not use identical rules; each has its own appetite for particular conditions, its own age bands and its own way of weighing the same set of facts. A situation one insurer is cautious about may be perfectly acceptable to another. That is exactly why a single "no" is not a verdict on whether you can be insured — it is one company's view, not the market's. Working across more than one insurer is what turns a first decline into a second, better-matched enquiry.

15. Why honesty protects you

This is the part that matters most, so it is worth stating plainly. If information is left out or is inaccurate, an insurer may later be able to reduce benefits, refuse a claim or cancel the policy — and that would happen at the very moment you needed the cover to work. Full, accurate disclosure is not just a rule to satisfy; it is what makes your policy dependable. The declaration you sign is the foundation the cover stands on. When in doubt, declare it.

The clearest way to see this is to picture a future claim. If you ever need treatment, the insurer will look at your original declaration to confirm the cover applies — and a policy built on complete, accurate answers gives them nothing to query, so the claim is straightforward at the very time you most need it to be. By contrast, an omission that seemed harmless when you filled in the form can become the reason a claim is delayed or refused later, precisely when you are least able to deal with it. Honest disclosure is not a favour to the insurer; it is the thing that protects you, because it converts your policy from a piece of paper into cover you can actually rely on. A few extra minutes of care at the application stage is what buys you peace of mind for the whole year ahead.

The matrix below is a quick reference for what generally gets declared and why. It is a guide to the spirit of disclosure, not a substitute for the actual questionnaire — always answer the specific questions you are asked.

16. Common myths, calmly corrected

A lot of the worry around medical questions comes from beliefs that simply are not true. Setting them side by side with the reality tends to take the fear out of the process. The single thread running through all of them is that honesty is both the safest and the most sensible approach.

17. A worked timeline example

People often ask how the days actually flow once medical questions are involved. The example below is illustrative only — real timings vary by insurer and by individual — but it shows the shape of the process and, in particular, why raising medical points early tends to save time rather than cost it.

The point of setting it out this way is simple: the one stage that can add unpredictable time is the follow-up in step three, and that is precisely the stage you shorten by flagging your medical points at the very start. Raise them on day one and the insurer can assess the full picture in one pass; leave them until after a figure has been quoted and you invite exactly the back-and-forth you were hoping to avoid. Early honesty is the fastest route, not the slowest. If your appointment is near, that is all the more reason to say what is relevant straight away — see when to buy and, if time is tight, urgent cover.

18. Timing and deadlines

Medical questions can add a little time to the process — a questionnaire to complete, and occasionally a follow-up before a firm quote can be given. Flagging things early keeps that to a minimum. If your appointment is close, tell us what is relevant and we will be honest about what is realistic in the time available. See when to buy and urgent cover.

19. Requesting a quote with medical points

If you have anything medical to mention, the best approach is to say so when you request a quote. It does not slow things down in the way people fear — it actually speeds them up, because we can go straight to the insurer most likely to assess your situation well. Tell us what is relevant, and we will handle the rest discreetly. See what information is needed for a quote, and our complete guide for how the medical stage fits into the whole process.
