When you apply to the National Disability Insurance Scheme, you may be asked to provide evidence of your disability or impairment. One key part of this process is the NDIS Impairment Notice. This document often raises questions for participants, especially those new to the scheme. So, what exactly is it, why is it important, and how should you approach it? Let’s break it down step by step.
What is an NDIS Impairment Notice?
An NDIS Impairment Notice is an official request for information. The National Disability Insurance Agency (NDIA) may send it to you if they need further medical or functional details about your disability before making a decision on your application.

In simple terms, it’s a way of saying: “We need more evidence to confirm your eligibility.”
This notice usually asks for reports from doctors, specialists, or allied health professionals that show how your condition affects your daily life.
Why Does the NDIA Send an Impairment Notice?
The NDIA is required to make fair and accurate decisions. If the information in your initial application isn’t enough, they issue an impairment notice to give you an opportunity to provide more.
Common reasons include:
- Your medical evidence is incomplete.
- The reports don’t clearly explain how your condition is permanent.
- Functional impacts on daily life need to be better documented.
Many participants choose to work with support providers like Apex Support Services early on. Having guidance during this stage can make it easier to gather the right information before the notice even arrives.
How Much Time Do You Have to Respond?
The impairment notice will state a specific timeframe—usually 28 days—to submit the requested evidence. If you don’t provide the information within that period, the NDIA may decide your application without it, which could affect your eligibility outcome.
If you need more time, you can request an extension, but it’s important to do this before the deadline.
What Kind of Evidence Should You Provide?
The NDIA is looking for evidence that your condition is permanent and significantly impacts daily life. This might include:
- Specialist medical reports.
- GP letters confirming diagnosis and ongoing treatment.
- Functional assessments from occupational therapists, psychologists, or physiotherapists.
- Hospital discharge summaries or chronic condition management plans.
The stronger and clearer the evidence, the better your chances of a smooth approval process.
What Happens if You Ignore the Notice?
If you don’t respond to an impairment notice:
- The NDIA may decide your application based only on existing information.
- This often results in a decline of eligibility.
- You may then need to appeal the decision, which takes extra time and energy.
So, it’s always better to respond on time with as much detail as possible.
Can You Get Help With the Process?

Yes, absolutely. Many participants find the impairment notice stage stressful, but you don’t have to handle it alone. Support coordinators, advocacy groups, or disability service providers can:
- Help you understand the exact requirements of the notice.
- Connect you with the right medical professionals.
- Ensure your evidence is complete and clearly written.
At Apex Support Services, we regularly assist participants with navigating these requests. Having someone in your corner can make the process far less overwhelming.
FAQ: NDIS Impairment Notices
1. Do all NDIS applicants receive an impairment notice?
No. Not everyone will get one. They are only issued if the NDIA feels your application doesn’t have enough supporting evidence.
2. Can I send old medical reports?
Yes, but they must still be relevant. If a report is too old and doesn’t reflect your current functional capacity, the NDIA may not accept it.
3. Who should write my evidence?
Ideally, specialists or allied health professionals with expertise in your condition. Their reports carry more weight than general statements from non-specialists.
4. What if my condition is invisible, like a mental health condition?
That’s fine. You still need to show permanence and functional impact. For example, a psychologist can provide evidence on how your condition affects your ability to work, study, or live independently.
