Figuring out exactly what the National Disability Insurance Scheme (NDIS) will pay for can be confusing, but understanding the funding rules puts the control back in your hands. To get any service or item approved in your plan, it must meet the strict criteria for reasonable and necessary NDIS supports.
This article provides a clear, definitive breakdown of what the National Disability Insurance Agency (NDIA) looks for, examples of what is commonly funded and practical steps to ensure your funding requests are approved.
What Does “Reasonable and Necessary” Mean in the NDIS?
Understanding the NDIS reasonable and necessary definition is essential, as it is the core rule the National Disability Insurance Agency (NDIA) uses to determine what to include in your plan.
This concept exists to ensure that all funding is fair, directly related to your disability and provides practical assistance for your everyday life.
Every single funding decision relies on these guidelines, meaning no support is approved unless it meets this specific standard.
What is the Criteria for “Reasonable and Necessary” Under the NDIS?
Under the NDIS Act, any support you request must meet strict legislative rules before it can be funded. To be approved, the NDIS reasonable and necessary criteria require that a support must:
- Assist you to pursue your individual goals and aspirations.
- Help you undertake activities that facilitate your social and economic participation.
- Represent value for money compared to alternative options.
- Be effective and beneficial for your specific needs.
- Take into account what is reasonable to expect from your family, carers and informal networks.
- Be most appropriately funded through the NDIS rather than other government systems like health or education.
Examples of Supports That Are Usually Funded
The NDIS regularly funds services and items that directly address your disability support needs.
Common examples include:
- Therapy supports such as occupational therapy, speech pathology and physiotherapy.
- Assistive technology like mobility equipment and specialised communication devices.
- Personal care assistance for daily routines and household tasks.
- Capacity building supports designed to teach you new skills and increase your independence.
Examples of Supports That Are Commonly Rejected (And Why)
The NDIS will not fund items that do not meet the strict legislative rules. Examples of supports that are typically denied include:
- Everyday living costs like rent, groceries and utility bills, because everyone pays for these regardless of whether they have a disability.
- General lifestyle items such as standard gym memberships or concert tickets, as these are considered personal expenses.
- Any support or service that is not directly linked to your specific disability.
How the NDIA Actually Decides What Gets Funded
When developing your plan, an NDIA planner carefully considers your living situation, informal supports and personal goals. They rely entirely on the information and evidence you provide to make consistent decisions. The planner must review NDIS laws and ensure the requested support meets every single part of the criteria before approving the funding.

What Evidence Do You Need to Prove a Support is Reasonable and Necessary?
Different types of supports require different levels of proof before they can be approved. Strong evidence typically comes in the form of detailed assessments and reports from qualified allied health professionals. These documents must clearly outline your disability support needs and show exactly how the requested item will help you build capacity. A vague letter from a general practitioner is rarely enough to secure funding.
How to Clearly Justify a Support in Your Plan
When requesting funding, you must draw a direct line between your disability, the requested support and your NDIS goals. Detail exactly how the service or item will impact your daily life and improve your independence. A straightforward approach is to describe the barriers you currently face, how the specific support will remove those barriers and why cheaper alternatives will not work.
Why Supports Get Rejected (And How to Avoid It)
Claims are frequently denied when they do not align with the strict NDIS pricing arrangements or funding rules. Another major reason for rejection is providing weak documentation that fails to connect the support directly to your disability. To give yourself the best chance of approval, always ensure your allied health reports explicitly address the reasonable and necessary guidelines.
What to Do If Your Support Is Not Approved
If you disagree with a funding decision, you have the right to request an internal review within three months of receiving your plan. An independent NDIA officer will re-examine your case, look at the original reasons for the decision and consider any new evidence you provide. If you are still unsatisfied with the outcome, you have 28 days to request an external review through the Administrative Review Tribunal.
