What happens if I lie on the insurance health questionnaire?

No, You must not lie on the health questionnaire of a medical or life insurance policy.. Hiding a diagnosed illness, a recent surgery, an ongoing test, or a relevant history can have significant consequences: exclusions, denial of a benefit, reduced compensation, cancellation of the policy, or even loss of the right to claim if there is negligence or serious fault.

What is the health questionnaire of an insurance policy?

The health questionnaire It is the document used by the insurer to assess the risk before contracting a medical insurance, a life insurance, an accident insurance with certain guarantees or any other personal insurance in which the state of health may influence the acceptance, price or conditions of the policy.

It can include questions about:

• Diagnosed illnesses.
• Surgeries or hospital admissions.
• Current medical treatments.
• Pending diagnostic tests.
• Medication consumption.
• Cardiovascular, oncological, respiratory, digestive, neurological or endocrine diseases.
• Injuries, sequelae or physical limitations.
• Weight, height, lifestyle habits or professional activity.
• Recent job losses or recognized disabilities.

Not all questionnaires are the same. Some insurers ask very specific questions, while others use more general forms. The important thing is to answer clearly, veraconcise, and consistent with the medical information known.

What does the Insurance Contract Act say?

The Law 50/1980 on the Insurance Contract, It establishes that the policyholder must declare to the insurer, before the conclusion of the contract and in accordance with the questionnaire that it submits to him, all known circumstances that may influence the assessment of the risk.

This has two very important consequences:

• If the insurer asks, you must answer with veracidad: Hiding a disease, treatment, test, or background question can create problems.
• If the insurer does not ask, the duty is limited: The claimant is exempt from circumstances not included in the questionnaire or if a questionnaire is not submitted to them.

Therefore, it is not about “telling it all” without limits, but about correctly answering the question asked and not falsifying or hiding relevant information within the questionnaire.

Consequences of lying on the health questionnaire

If the insurer detects a relevant reservation or inaccuracy in the questionnaire, the consequences may vary depending on the type of insurance, the severity of the omitted information, the relationship to the accident, and whether there was negligence or serious fault.

Differences between health insurance and life insurance

Lying on a medical questionnaire can have consequences both in health insurance and life insurance, but the impact is usually different.

On mobile, slide the table horizontally to see all the information.

In health insurance, the problem usually arises when a medical authorization, test, intervention, or treatment related to a pre-existing condition is requested. In life insurance, the conflict can arise when beneficiaries claim the death or disability benefit and the insurer reviews the initial questionnaire.

What is considered a pre-existing medical condition?

A pre-existing medical condition It is an illness, injury, diagnosis, sequelae, or existing health condition before the policy is taken out. It may be formally diagnosed, in treatment, pending testing, or reflected in medical reports.

Not all pre-existing conditions have the same impact. Some may not affect hiring; others may lead to exclusions, overinsurance, deficiency, rejection of hiring, or the need for additional documentation.

See examples of information that may be relevant

• Diagnosed chronic diseases.
• Recent or planned surgeries.
• Pending medical tests.
• Continued treatments.
• Previous hospital admissions.
• Injuries with consequences.
• Oncological history within the legally declared limits.
• Cardiovascular, respiratory, digestive, endocrine, neurological or psychiatric pathologies.
• Labor-related injuries or health-related disabilities.

If you are unsure whether information should be disclosed, it is advisable not to decide based on intuition. It is advisable to review the specific question and seek advice before submitting the questionnaire.

Do I have to report any discomfort or symptoms?

Not necessarily. The reporting obligation refers to known circumstances that may influence the risk assessment and that are included in the questionnaire. A single complaint without a diagnosis or pending tests is not the same as a diagnosed pathology, a scheduled intervention, or ongoing medical treatment.

However, if the questionnaire asks in broad terms about persistent symptoms, pending tests, treatments, diagnosed illnesses, or recent medical consultations, it is necessary to answer carefully and veratruthfully.

Some practical examples:

• Occasional discomfort without a diagnosis: It may not be relevant if the questionnaire does not ask about such symptoms.
• Persistent pain with requested test: It is advisable to declare this if the question includes pending tests or symptoms under investigation.
• Diagnosed illness: It must be declared if the questionnaire asks about that disease or related medical history.
• Scheduled surgery: This is relevant information if the questionnaire asks about pending interventions, treatments, or tests.

Right to medical oblivion in life insurance

The right to oncological oblivion is one of the most important issues that must be incorporated into this content. Since Royal Decree-Law 5/2023, the holder of a life insurance policy is not required to declare whether he or the insured person has suffered from cancer when the period has elapsed. five years from the completion of the radical treatment without subsequent relapse.

After that period has expired, the insurer cannot consider these oncological backgrounds for the purposes of taking out life insurance nor discriminate or restrict the taking out of insurance on that basis.

In addition, the Insurance Contract Act prohibits discrimination based on disability, HIV/AIDS, or other health conditions, unless there are justified, provided, and reasonable reasons documented in advance and objectively.

You can consult the regulation in the Insurance Contract Law and in the Royal Decree-Law 5/2023.

Can an insurer access your medical historyrial?

An insurer They should not have free and unlimited access to your entire medical history.. Health data is particularly sensitive information and healthcare centers are responsible for managing and safeguarding the documentation of care.

The Spanish Data Protection Agency clarifies that, in the context of healthcare provided under an insurance contract, healthcare providers may communicate to the insurer the data strictly necessary for billing or managing the service, but this does not mean that they must provide the entire contents of the medical history.

You can consult the criteria of the Spanish Agency for Data Protection regarding the communication of data to insurers.

In practice, the insurer may request information, reports, authorizations, or medical documentation to assess a claim, an authorization, or a contract, but always within the applicable legal and contractual framework.

I've been kicked off the health insurance: can that happen?

When someone searches for “I’ve been kicked off my health insurance,” they are usually referring to one of these situations:

• The insurer has detected a pre-existing disease that has not been declared.
• A medical authorization has been rejected because it was considered pre-existing.
• The company has applied an exclusion for a specific pathology.
• The policy has been terminated due to inaccuracies in the questionnaire.
• The insurer has opposed the renewal within the terms and conditions of the contract.

Not all of these situations are the same. If the problem stems from alleged concealment in the questionnaire, it is necessary to review what was asked, what was answered, whether the disease was diagnosed, whether there was previous documentation, and whether the omitted information would have changed the risk assessment.

If the problem arises due to an illness that arose after the contract was signed, it is worth remembering that in personal insurance policies, the policyholder or insured person is not obliged to report any change in circumstances related to their state of health as a worsening of the risk.

What happens if I lie on a life insurance policy?

In life insurance, The consequences can be especially serious because there is often high capital and beneficiaries who depend on the benefit in the event of death or disability..

The Insurance Contract Act establishes a specific rule for life insurance: in cases of hesitation or inaccuracy that influence the risk assessment, the general rules apply. However, the insurer cannot challenge the contract once a year has passed since its conclusion, unless a shorter term has been set in the policy and, in any case, unless the policyholder acted with intent.

Therefore, if a relevant illness is deliberately hidden in a life insurance policy, the conflict can arise when the beneficiaries claim the insured capital.

What happens if I lie on a health insurance policy?

In health insurance, The problem usually arises when the insured person requests a medical authorization related to an illness, injury, or treatment before the contract is signed..

The insurer can check whether the pathology was pre-existing, whether it was diagnosed, whether there were relevant symptoms, whether there were pending tests, or whether the questionnaire explicitly asked about this situation.

The consequences may include:

• Denial of a medical authorization.
• Exclusion of a specific pathology.
• Application of deficiencies or contractual limitations.
• Review of the policy.
• Termination of the contract if legally permissible.
• Conflict over medical expenses already incurred.

Are there medical insurance plans without a health questionnaire?

Yes, there may be policies or plans that do not require a complete medical questionnaire, but that does not mean they cover any pre-existing conditions. Some plans without a questionnaire may have gaps, general exclusions, coverage limits, or specific conditions for pre-existing conditions.

There are also collective insurance policies or company agreements that may have different acceptance criteria, promotional periods without restrictions or special conditions, but the contractual documentation must always be reviewed.

Before you sign up for insurance without a questionnaire, it's worth checking:

• If it covers pre-existing illnesses.
• If there are shortages for surgery, hospitalization, childbirth, or complex tests.
• If it excludes pathologies diagnosed before contracting the service.
• If there are co-payments, limits, or sub-limits.
• If the medical picture fits your needs.
• Whether the policy is individual, collective, or linked to a company.

What to do if you made a mistake on the questionnaire?

If you notice that you answered incorrectly, omitted a piece of information, or do not know whether an item of information was relevant, it is advisable to act as soon as possible. It is not advisable to wait until an accident, medical authorization, or a claim occurs.

See recommended steps if you have made a mistake

• Check the questionnaire that you signed or sent.
• Check the exact question and the answer given.
• Compile relevant medical reports.
• Consult with your mediator before sending any improvised communications.
• Please request that the information be corrected or expanded if necessary.
• Keep supporting documents for any communication with the insurer.
• Do not present a disaster by again hiding the relevant information.

Correcting information does not guarantee that the insurer will maintain the same conditions, but it is usually better to maintain a policy with incorrect data that could cause problems later on.

How to fill out a health questionnaire correctly?

The best way to avoid problems is to fill out the questionnaire calmly, reading each question and answering it accurately.

• Don't answer memorably if you have doubts: Review reports, treatments, and approximate dates.
• Do not minimize relevant diagnoses: If an illness is diagnosed and you ask about it, you must declare it.
• Do not hide any pending evidence: A requested test can be relevant if the questionnaire asks about it.
• Do not confuse high medical qualifications with the absence of a background: Receiving discharge does not always eliminate the obligation to declare a diagnosed condition.
• Does not declare non-required oncological history: In life insurance, respect the right to forget about oncology when its requirements are met.
• Do not sign if you do not understand a question: Ask for clarification before submitting the form.
• Keeps a copy: Keep the questionnaire and the documentation you submit.

Common mistakes when contracting health or life insurance

• The assumption that the insurer will never review the questionnaire: You can do this by applying for authorization, surgery, or compensation.
• Hiding a disease because it is “already under control”: If she is diagnosed and asks about it, she must declare it.
• Not declaring a pending test: It may be relevant if the form asks about ongoing medical studies.
• Confusing lack and preexistence: The gap is an initial period without coverage; pre-existing conditions are a situation that exists before the contract is signed.
• Contracting only for price: A cheap policy may not be suitable if there are any medical conditions.
• Saying “no” out of fear that the premium will go up: It could create a bigger problem in the future.
• Do not seek advice: A mediator can help you present your case properly and compare alternatives.

When might it be advisable to switch health insurance?06

Switching health insurance can make sense if you are looking for better medical care, a lower price, fewer co-payments, or broader coverage. But if you have diagnosed conditions, ongoing treatments, or pending tests, the change should be carefully considered.

Before changing, check:

• If the new insurer requires a health questionnaire.
• If it will accept pre-existing diseases.
• There will be new shortages.
• If you retain current specialists.
• If there are ongoing treatments.
• It is worth considering changing or negotiating the current policy.
