"But You Don't Look Sick": How to Win a TPD Claim for an Invisible Illness

Imagine explaining to your insurance assessor why your chronic illness prevents you from working and they respond with, ‘But you don't look sick.’ For thousands of Australians living with invisible illnesses, this scenario is a harsh reality that can make or break their Total and Permanent Disability (TPD) claim.
The invisible nature of these conditions can create misunderstanding. While someone with a visible injury might receive immediate recognition of their limitations, those with invisible illnesses often face an uphill battle to prove their disability is real and permanent.
This practical guide will walk you through the specific strategies and evidence-gathering techniques that can transform your TPD claim from a frustrating rejection into a successful outcome.
Understanding Invisible Illnesses and TPD: Why the System Feels Unfair
Invisible illnesses have a broad range of conditions where symptoms aren't immediately apparent to outside observers. These include fibromyalgia, ME/CFS, multiple sclerosis, Crohn's disease, lupus, severe anxiety, PTSD, and depression. These are conditions that can be profoundly disabling while remaining largely hidden from view.
Traditional disability assessments rely heavily on observable physical limitations and objective test results. When you can't point to a broken bone or a clear scan showing damage, insurers become suspicious. This creates what advocates call the ‘credibility gap,’ where genuine disability is questioned simply because it can't be easily seen or measured.
Research shows that mental health conditions now represent a significant portion of TPD claims, yet they face higher rates of initial rejection compared to claims for visible disabilities. You might have good days where you appear relatively normal, followed by devastating flare-ups that leave you bedridden, a pattern that can confuse assessors unfamiliar with invisible illness presentations.
What Insurers Need: The Evidence Gap for Invisible Illness
Understanding what insurers look for can help you bridge the evidence gap that makes invisible illness claims so challenging. TPD claims require clear medical evidence and proof of impact on work capacity. The challenge lies in providing this evidence when your condition doesn't show up on standard tests or scans.
Insurers typically expect to see objective medical findings such as blood tests, imaging results or measurable physical limitations. When these aren't available, they may question whether your condition is genuinely disabling or permanent. This reflects a system built around visible and measurable disabilities rather than subjective symptom experiences.
Building Your Case: The Critical Role of Medical Documentation
Your medical records form the foundation of any successful TPD claim, but for invisible illnesses, they need to tell a more complete story than standard healthcare documentation typically provides. Consistent, long-term medical records are crucial, such as regular GP and specialist visits, detailed treatment history and comprehensive medication lists.
Start by ensuring every medical appointment is properly documented. Don't settle for brief, generic notes like ‘reviewed, stable.’ Ask your healthcare providers to record specific symptoms, functional limitations and how these impact your daily activities. When you visit your GP or specialist, always update them on any changes in your condition, like new symptoms or worsening limitations and ensure these updates are documented in your file.
Request detailed consultation notes and reports from all your treating doctors. These should go beyond basic diagnosis to explain how your condition affects your ability to work and function. For invisible illnesses, your medical team must understand your work history and specific job requirements so they can comment on relevant functional limitations.
Keep records of all treatments attempted, including medications, therapies, lifestyle modifications and alternative approaches. Document treatment responses, side effects and reasons for changes or discontinuation. This comprehensive treatment history demonstrates the ongoing nature of your condition and your efforts to manage symptoms.

Articulating Your Daily Reality: Describing the Impact of Pain, Fatigue, and Cognitive Dysfunction

Describe the difference between your good days and bad days in detail. On a bad day, what specific tasks become impossible or extremely difficult to complete? Can you shower independently? Do you struggle to prepare meals or manage basic household tasks?
Be specific about how symptoms like chronic pain, overwhelming fatigue or cognitive dysfunction limit your ability to perform work-related activities. Do you struggle to concentrate on reading for more than a few minutes?
Many successful claims include statements from family members, friends or former colleagues. With their consent, ask people who know you well to provide written statements about how they've seen your condition affect your daily life and work performance.
You may be able to complete certain tasks occasionally, but the key question for TPD claims is whether you can perform them reliably on a full-time basis. Explain how symptoms worsen with sustained activity or stress and how this affects your ability to maintain consistent work performance.
Keeping a Symptom Diary: Your Secret Weapon
A detailed symptom diary can be your most powerful tool for bridging the evidence gap in invisible illness claims. This daily record provides objective documentation of subjective experiences, creating a detailed picture of how symptoms fluctuate over time and impact daily functioning.
Record symptom severity using consistent rating scales, for example, rating pain or fatigue on a scale of 1-10 each day. Document triggers and patterns, such as how symptoms worsen after physical activity, stress or weather changes. Note the impact of symptoms on specific activities, such as struggling with self-care or having to cancel social activities.
Present your diary as part of your claim documentation, highlighting patterns and key examples that illustrate your limitations. Ask your GP or specialist to review the diary and reference it in their reports to insurers. Symptom diaries have been cited in insurer decision letters as demonstrating the day-to-day impact of conditions, which can tip the balance in close-call cases.
Specialist Reports: Why They Matter and How to Get the Most Out of Them
Independent specialist reports carry significant weight with insurers because they're viewed as more objective and authoritative than reports from treating doctors. The quality of specialist assessment can significantly influence claim outcomes, making specialist selection and preparation crucial components of successful claim preparation.
You want to choose a specialist who has experience in your specific condition and, ideally, familiarity with disability assessments. Different medical specialists may have varying perspectives on the same condition, so ensure your specialist understands both your illness and the assessment requirements.
Prepare thoroughly for specialist appointments by sharing your symptom diary and work history before the assessment. Request that their report specifically addresses your ability to perform work-related tasks, not just your general health status.
Preparing for Insurer Assessments: What to Expect and How to Advocate for Yourself
Insurer-arranged independent medical examinations are a common practice for TPD claims. These appointments can be particularly challenging for individuals with invisible illnesses.
Expect a structured interview with possible physical and cognitive examinations. The assessor may not be an expert in your specific condition, so don’t be afraid to educate them about your symptoms and limitations.
Take your symptom diary, medical report and any other supporting evidence with you. Prepare a list of key points about your daily challenges and functional limitations. Practice explaining your worst days and how they impact your ability to work consistently.
The most important thing to do in these assessments is to be completely honest about your limitations. Explain how symptoms affect you when assessors aren't present. If you've pushed yourself to attend the appointment despite feeling unwell, make this clear. The goal is to provide an accurate picture of your limitations, not to impress the assessor with your resilience.

Overcoming Common Challenges and Setbacks
The TPD claims process for invisible illnesses is known for delays, requests for additional evidence and initial rejections. Understanding these challenges and having strategies to address them can help you persist through setbacks.
Average processing times for complex claims are usually around 12-14 months, with many claimants facing multiple requests for supplementary evidence or repeat assessments.
It’s important to respond promptly to all requests for information, even if they seem repetitive or unreasonable. If you don't understand a request or need clarification, ask for a written explanation.
If your claim is denied, request a detailed written explanation of the decision. Review your documentation for any gaps that might have contributed to the rejection. Many initially unsuccessful claims are approved on appeal when additional evidence is provided or when claimants seek professional advocacy support.
If internal appeals are unsuccessful, you can make a complaint to the Australian Financial Complaints Authority (AFCA) or seek independent advocacy.
Your Path Forward: Taking Control of Your Claim
Winning a TPD claim for an invisible illness requires patience and strategic preparation to get the outcome you require. Your condition is real, your limitations are valid and you deserve fair consideration of your claim.
Remember to build comprehensive medical documentation that clearly links your diagnosis to specific functional limitations. Maintain detailed symptom records that demonstrate the day-to-day impact of your condition. Work with specialists who understand both your illness and the assessment requirements to provide compelling expert opinions.
Reach out and connect with others who understand your experience through condition-specific support groups and advocacy organisations. Their practical advice and emotional support can be invaluable during difficult periods.
Most importantly, don't give up if you face initial setbacks. Many successful claimants experience rejections, delays or requests for additional evidence before achieving positive outcomes.
