Medical Disclosure in Insurance Applications: Common Mistakes to Avoid

Written by Christopher Hall, AdvDipFP | Authorised Representative, AFSL 526688 | June 2026

Both over-disclosure and under-disclosure create problems in Australian life insurance applications. Under-disclosure risks claim denial; over-disclosure can generate exclusions and premium loadings that do not reflect an actual medical risk — and that can take significant effort to remove. The correct approach is to answer every question accurately and completely, and not to volunteer information beyond what has been specifically asked. Retail life insurance policies in Australia are assessed through tele-underwriting — structured 25–45 minute interviews (TAL, Guide to Teleinterviews) covering health history, lifestyle, occupation and income. The most common disclosure errors — incomplete physiotherapy history, undisclosed mental health consultations, and conditions managed by medication — create unnecessary exclusions or loadings that accurate disclosure would have avoided. Christopher Hall, AdvDipFP, Authorised Representative, AFSL 526688, has completed more than 500 life insurance policy reviews for Australian families, and explains how to approach disclosure correctly. For the broader assessment framework, the full policy review framework covers what a comprehensive review involves.

What Is Medical Disclosure — and What Does the Law Require?

Medical disclosure is the process of providing accurate health information to an insurer when applying for life, income protection, or TPD cover. Insurers use this information to assess risk, decide whether to offer cover, and set the terms — including any exclusions or premium loadings — that will apply to the policy.

Since 2021, Australian applicants are required to take reasonable care not to make a misrepresentation to their insurer (Insurance Contracts Act 1984 (Cth), as amended, effective 5 October 2021). This replaced the previous, stricter duty of disclosure. In practical terms, it means answering every question asked truthfully and in full — but it does not require volunteering information the insurer has not asked about.

If a material misrepresentation is identified during a claim, the insurer may deny the claim, reduce the benefit proportionally, or void the policy entirely. It is worth noting that APRA data shows 95% of finalised life insurance claims are paid by Australian insurers (APRA, Claims and Disputes Statistics, 2022) — indicating that most insurers apply a reasonable standard, including in disputed disclosure cases. However, the 5% of claims that are not paid often involve disclosure issues, and the consequences of being in that category are severe.

What Medical Information Must Families Disclose in Insurance Applications?

Retail insurance policies in Australia require comprehensive medical disclosure through structured tele-underwriting interviews. These interviews, lasting 25–45 minutes on average (TAL, Guide to Teleinterviews), cover multiple disclosure categories that determine policy terms and pricing.

Tele-underwriters ask specific questions about current health status, past medical treatments, ongoing medications, family medical history, lifestyle factors including smoking and alcohol consumption, occupation and associated physical demands, and income verification for benefit calculations. The interview format allows families to provide context and detail that written applications cannot capture.

In Christopher Hall's experience, the tele-interview process serves dual purposes: gathering information for underwriting decisions whilst creating a documented record of disclosed facts. This upfront process distinguishes retail policies from group insurance products, where minimal underwriting may occur initially but disclosure gaps surface during claims assessment.

The structured interview removes ambiguity that written applications create. When tele-underwriters ask specific questions, families can seek clarification immediately rather than guessing whether particular medical history requires mention. This interactive process reduces misunderstandings that generate unnecessary policy restrictions, and supports the broader picture of how underwriting handles known health history.

How Do Incomplete Disclosures Differ from Dishonest Non-Disclosure?

Understanding the distinction between incomplete and dishonest disclosure helps families approach tele-interviews appropriately. Christopher Hall explains this difference using practical examples from application experiences.

Weight disclosure illustrates the spectrum clearly. A family member stating 80 kilograms when their actual weight measures 84 kilograms represents incomplete disclosure — minor variance from rounding or recent fluctuation. The same person stating 80 kilograms whilst weighing 110 kilograms constitutes dishonest non-disclosure, materially misrepresenting health status that affects underwriting assessment.

Medication disclosure creates frequent incomplete-versus-dishonest scenarios. A family member failing to mention two months of anti-inflammatory medication may genuinely forget short-term treatment or consider it insufficiently significant for disclosure. Omitting long-term cholesterol medication, thyroid medication or hormone replacement therapy demonstrates a material non-disclosure, as ongoing pharmaceutical treatment materially affects health assessment.

The tele-interview process addresses this distinction directly. When families encounter disclosure uncertainty, Christopher Hall's guidance emphasises asking the tele-underwriter for clarification during the interview itself. Underwriters can explain what information they require and why particular medical history matters for risk assessment.

What Are the Most Common Medical Disclosure Mistakes?

Across Arrow Equities' review experience, a consistent set of disclosure gaps recurs (C. Hall, Arrow Equities, proprietary policy review data). Most are inadvertent — the product of rushed applications, misunderstood questions, and incorrect assumptions about what is and is not relevant.

Mental health consultations with a GP. The single most common disclosure gap involves mental health treatment — particularly brief, resolved episodes of anxiety or stress managed through a GP. Someone who consulted their GP about workplace stress and received a short course of medication several years ago may not consider it relevant to an insurance application. Insurers do. If a later claim has any mental health component, the insurer will investigate medical records, and an undisclosed GP consultation will be identified. This matters because mental health claims now represent almost one in three TPD claims (CALI, Life Insurance in Focus, September 2023) — making the category material to insurers' risk assessment, and relevant to anyone reviewing how TPD insurance works.

Controlled conditions misunderstood as non-conditions. High blood pressure managed by daily medication is still a diagnosed condition requiring disclosure. High cholesterol controlled by statins is still a diagnosed condition. A common misconception is that "it's under control so it doesn't count." The correct position is that a condition managed by medication is a disclosed condition — the medication is itself evidence of the diagnosis.

Specialist consultations where results were clear. A referral to a cardiologist that returned a clear result, a dermatology consultation, an ENT visit — these are all specialist consultations that should be disclosed where the application asks about them. The purpose of the consultation matters to the underwriter, not only the outcome. Medical billing records will reveal undisclosed specialist visits during any claim investigation.

Family medical history gaps. Questions about family medical history typically ask about conditions diagnosed in parents or siblings before age 60. Common gaps include a parent diagnosed at 62 (technically outside the window but worth disclosing if the question is broadly framed), a sibling's condition the applicant was uncertain about, or unknown paternal medical history that is best recorded as "unknown" rather than left blank.

Physiotherapy — the most frequent grey area. Physiotherapy is the single biggest cause of unnecessary policy exclusions across Arrow Equities' review experience (C. Hall, Arrow Equities, proprietary policy review data). Australian families commonly consult physiotherapists for massage therapy, injury management and general musculoskeletal maintenance. When families report "seeing a physiotherapist for back issues," insurers frequently interpret this as evidence of a pre-existing back condition warranting a full musculoskeletal exclusion. The error stems from incomplete context rather than dishonesty: "I ran a marathon, experienced normal post-race soreness, and consulted a physiotherapist for massage and recovery" demonstrates temporary, activity-related treatment rather than a chronic condition. The case studies below show how this plays out in practice.

Three Case Studies From Christopher Hall's Review Practice

(C. Hall, Arrow Equities, proprietary policy review data)

Case Study 1 — Over-disclosure: a cold that complicated an application. During a phone-based underwriting assessment, a client was asked generally about their current health. The client mentioned they had taken a day off work because their child was unwell and they had felt under the weather themselves — minor symptoms, no GP visit, resolved within a day or two. The underwriter, following standard procedure, placed the application on hold and asked for a doctor's certificate confirming recovery before the application could proceed. This introduced an unnecessary delay into what was, by any reasonable measure, a trivial health event. The correct approach was to describe the current state of health — which was good — and not to volunteer passing symptoms that had no medical relevance. The lesson is not to be dishonest. It is to understand the scope of the question being asked and to answer it accurately without elaborating beyond what is relevant.

Case Study 2 — Over-disclosure: the physiotherapist as risk indicator. A significant number of Australians use physiotherapists not to treat a diagnosed condition, but to improve exercise technique, manage general activity, or get professional guidance on training safely — often using private health cover subsidies. In underwriting, however, a physiotherapy consultation is frequently treated as evidence of a musculoskeletal issue. Where an application discloses physiotherapy attendance, the default underwriting response from many insurers is to apply a full exclusion for the relevant body area — back, knee, shoulder, or otherwise — regardless of the reason the physiotherapy was sought. This places the adviser in the position of having to claw back a full exclusion that was never warranted, by obtaining detailed clinical notes from the treating physiotherapist confirming the consultations were preventive and that no underlying condition was identified. In Christopher Hall's experience this advocacy is often successful — but it is time-consuming and entirely avoidable. The correct approach is not to conceal physiotherapy attendance where it is asked about, but to describe the purpose accurately, and ideally to discuss the framing with an adviser before completing the application.

Case Study 3 — Under-disclosure, and the insurer pays anyway. A client who had understated the extent of a health condition during their original application subsequently claimed on that policy — for the same condition they had inadequately disclosed. During the claims process, the insurer investigated the original application and identified the discrepancy. On a straightforward reading, the policy may well have been issued with a full exclusion for the condition, or declined at inception; the insurer had reasonable grounds to deny the claim. The insurer paid the claim regardless — giving the policyholder the benefit of the doubt. This aligns with the broader data: APRA's Claims and Disputes Statistics show 95% of finalised life insurance claims are paid (APRA, 2022). Insurers are not, as commonly assumed, looking for reasons to avoid paying. The caution this case carries is not that under-disclosure is safe — it is that the 5% of cases where claims are denied can be catastrophic, and relying on an insurer's goodwill is not a risk management strategy.

Case study outcomes reflect individual circumstances and are not a reliable indicator of future results. Individual outcomes depend on personal health status, policy terms and insurer underwriting criteria.

What the 30% Figure Actually Means

Approximately 30% of policies reviewed by Arrow Equities carry exclusions or loadings that warrant re-assessment (C. Hall, Arrow Equities, 500+ policy reviews). This is not a disclosure-failure rate. Exclusions and loadings applied by an insurer at underwriting are known, documented policy terms — not gaps or errors. They reflect the insurer's assessment of disclosed medical information at the time the policy was issued.

What the figure highlights is that a meaningful proportion of policyholders are carrying restrictions on their cover that may no longer be appropriate. A condition that generated an exclusion at application may have since resolved. A loading applied five years ago may be reviewable in light of subsequent health history. These are not disclosure issues — they are policy review opportunities.

Underwriting standards, and the way a disclosed condition is assessed, also differ between insurers — a condition that attracted an exclusion or loading with one insurer may be assessed differently by another. Arrow Equities reviews cover across the major Australian life insurers, including AIA, TAL, Zurich, MetLife, OnePath and Acenda. For policyholders weighing whether restrictions are still warranted, this cross-insurer view is the practical value of a review.

When Should Families Disclose Past Medical Treatments?

Timeframe considerations affect disclosure requirements, though families benefit from erring toward complete disclosure rather than arbitrary timeline assumptions. Tele-underwriters specify relevant periods for various medical history categories during structured interviews — typically ranging from two to ten years depending on condition categories. Cardiovascular issues, cancer history and chronic conditions generally require longer disclosure periods than minor surgical procedures or short-term medication use.

The "left it too late" scenario illustrates disclosure timing. Families experiencing symptoms but delaying insurance applications until after medical investigation or diagnosis face different underwriting outcomes than those obtaining coverage before symptom onset. Once a diagnostic process commences — a specialist referral ordered, a scan booked, or results pending — disclosure obligations intensify even without a definitive diagnosis, and applications are commonly placed on hold until the investigation concludes. This is exactly why reviewing cover before booking a cardiac calcium scan or similar investigation matters: in-force cover is protected, but a new application lodged mid-investigation is not.

Medication history requires disclosure based on usage duration and purpose. The distinction is between short-term medication courses (anti-inflammatories for acute injury) and long-term pharmaceutical management (cholesterol, thyroid, hormone replacement therapy). Tele-underwriters probe medication history to understand underlying health conditions, not simply to catalogue prescriptions. Families uncertain about specific timeframe requirements benefit from asking the tele-underwriter directly during the interview.

What Rights Do Families Have During the Medical Disclosure Process?

Australian families completing insurance applications hold specific rights during underwriting. Understanding them helps families engage confidently whilst ensuring fair treatment.

Families may request copies of all medical evidence used in an underwriting decision within ten business days (TAL, Guide to Underwriting). This includes GP reports, specialist letters and pathology results — access that allows families to verify the accuracy of the records forming the basis for coverage decisions. Where underwriters request additional information, families may involve their treating doctors in providing context; comprehensive medical documentation often resolves underwriting queries more favourably than incomplete responses.

The underwriting timeline provides structure: insurers typically complete decisions within five business days once all required information arrives (KPMG Australia, Life Insurance Industry Insights 2023). Tele-interview recordings also create a permanent disclosure record, documenting exactly what was disclosed should a future dispute arise. Families maintaining uncertainty about their obligations, or disagreeing with an underwriting decision, may seek advice from an AFSL-licensed insurance adviser.

How to Approach Disclosure Correctly

Three principles govern medical disclosure in an Australian insurance application.

Step 1 — Answer what is asked, accurately and completely. Read each question carefully and answer truthfully and in full. This includes conditions managed by medication, past treatment that has since resolved, and specialist consultations even where results were clear. The current legal standard — reasonable care not to mislead — requires complete answers to the questions asked.

Step 2 — Do not volunteer information beyond the question asked. There is no legal obligation to volunteer information the insurer has not asked about. Where a question asks about diagnosed conditions, answering about a passing illness without a diagnosis goes beyond what is required and may create underwriting complications that do not reflect an actual medical risk.

Step 3 — If uncertain, seek advice before answering. Where there is any uncertainty about whether a health event, consultation, or medication is relevant to a specific question, families may wish to consult a qualified adviser before completing the application. An experienced adviser understands the underwriting implications of different answers and can help frame an accurate, appropriately scoped response — avoiding both the under-disclosure risk and the over-disclosure problem. This is particularly important for physiotherapy history and mental health consultations, the two most common sources of underwriting complications in Christopher Hall's experience.

In Christopher Hall's experience across more than 500 reviews, professional guidance during the disclosure process frequently prevents exclusions that stem from poor communication rather than an actual health risk. Families particularly benefit from this support where medical history includes potentially misunderstood items — physiotherapy, mental health consultations, minor procedures or chronic medication management. Arrow Equities' application support includes a medical history review before the tele-interview, guidance on disclosure requirements and timeframes, support during the tele-underwriting call, and advocacy with insurers regarding underwriting decisions.

Frequently Asked Questions

What is the duty of disclosure in Australian insurance applications?

Since 2021, Australian insurance applicants are required to take reasonable care not to make a misrepresentation to their insurer (Insurance Contracts Act 1984 (Cth), as amended). This replaced the previous, stricter duty of disclosure. It means answering all questions asked truthfully and completely — including conditions managed by medication and past specialist consultations — but does not require volunteering information that has not been specifically asked for.

What medical information requires disclosure in retail insurance applications?

Retail applications require disclosure of all medical conditions, treatments, medications and health-related lifestyle factors an insurer considers material to risk assessment. Tele-underwriting interviews lasting 25–45 minutes cover current health status, past medical history, family medical history, medication use, surgical procedures, ongoing treatments and lifestyle factors. Families uncertain about specific requirements benefit from asking the tele-underwriter directly rather than making independent judgments about materiality.

What happens if a disclosure mistake is found at claim time?

The insurer may deny the claim, reduce the benefit proportionally, or void the policy entirely. The outcome depends on whether the non-disclosure was deliberate or inadvertent, and whether the insurer would have offered cover had the information been disclosed. APRA data shows 95% of finalised claims are paid (APRA, 2022) — but the consequences of being among the 5% can be severe and irreversible.

Why does physiotherapy treatment create unnecessary policy exclusions?

Physiotherapy disclosure frequently generates exclusions because families report "seeing a physiotherapist for back issues" without explaining context. Insurers interpret brief physiotherapy mentions as evidence of a chronic musculoskeletal condition warranting exclusion. Complete disclosure explaining circumstances — marathon recovery, sports injury management, preventative maintenance — allows underwriters to assess risk appropriately. The purpose of the physiotherapy, not just the attendance, is what matters (C. Hall, Arrow Equities, proprietary policy review data).

What challenges prevent families from disclosing mental health treatment?

Mental health disclosure challenges stem from shame, embarrassment and privacy concerns. Discussing psychological treatment, counselling or psychiatric medication with a telephone interviewer creates discomfort many families avoid through non-disclosure. However, mental health history significantly affects policy terms, and undisclosed treatment generates exclusions that appropriate disclosure might minimise. Professional support helps families approach the conversation with appropriate context whilst maintaining dignity.

What does it mean when an insurance policy has an exclusion or loading?

An exclusion means the policy will not pay claims related to a specified condition or body part. A loading means an additional premium is charged to reflect higher assessed risk. Approximately 30% of policies reviewed by Arrow Equities carry exclusions or loadings that warrant re-assessment — in some cases the underlying condition has since resolved and the restriction may be reviewable (C. Hall, Arrow Equities, 500+ policy reviews).
