NDIS Plan Reviews — When and How to Request One

If your family member's situation has genuinely changed since their NDIS plan was written — a new diagnosis, a move, a support that isn't working the way everyone hoped, needs that have grown or eased — you don't have to wait for the next scheduled check-in. You can ask the National Disability Insurance Agency (NDIA) to reassess the plan now. This is a routine, everyday part of how the NDIS works, and it is a completely different process from formally appealing a decision you disagree with — that's a separate topic, covered in our guide to reviews and appeals.

Two different pathways — know which one you need

The NDIS "changing your plan" system covers two distinct things, and mixing them up wastes time and causes frustration:

• Plan reassessment (this guide): your circumstances have genuinely changed, so the current plan no longer matches what's actually needed. You're asking for it to be updated.
• Review of a decision (a separate, formal appeals process): you disagree with a decision the NDIA has already made — a rejected support, a funding amount, an access decision — and you want it reconsidered. See Your NDIS request was declined — reviews and appeals for that process.

A simple test: if life has changed, ask for a reassessment. If life hasn't changed but you think the NDIA got a decision wrong, that's a review of a decision instead.

What typically triggers a legitimate reassessment request

The NDIS describes a change of situation broadly — anything that has changed in your life that affects disability support needs. In practice, families most often request a reassessment because of:

• A new diagnosis, or an existing condition changing in a way that affects daily function
• Support needs increasing or decreasing — more, less, or different supports are now needed
• Moving house, including moving into or out of residential aged care, or moving interstate
• A support or service that isn't working as the current plan intended
• A change to informal support — for example, a family carer who can no longer provide the same level of help
• The plan approaching its end date — the NDIA checks in roughly 2–3 months beforehand to see whether the next plan needs different supports

How to actually request one

You don't need to wait for a scheduled check-in if something has genuinely changed. Ways to raise it:

• Phone: NDIA on 1800 800 110
• Online: submit an enquiry through the NDIS service hub, or via the my NDIS app
• In person: speak to your Local Area Coordinator or "my NDIS" contact, or visit a local NDIA office
• By form: complete the "change of details or change of situation" form (available from ndis.gov.au)
• At a planned reassessment meeting: if a check-in is already scheduled, raise the change there

Some smaller updates — like adjusting how funding is managed, or clarifying a goal — can often be handled as a straightforward plan variation without a full reassessment. Larger changes, where different supports are needed, usually require a fuller reassessment with supporting evidence. If you're not sure which applies, your NDIA contact can tell you.

What evidence strengthens the request

NDIS guidance is clear that a reassessment decision is made using the evidence provided, so it's worth preparing before you contact them:

• Reports or letters from treating health professionals — allied health providers, therapists, or support workers — describing the change and how it affects daily function
• Support coordinator notes, if your family member has a support coordinator, summarising what has changed and why
• A GP letter, where the change is tied to a clinical diagnosis or medical event — useful supporting context, though it should sit alongside allied health evidence rather than replace it
• Evidence that focuses specifically on how the change affects support needs, rather than only restating a diagnosis

If you're unsure exactly what evidence is needed for your situation, ask your NDIA contact before you submit — it can save a back-and-forth later.

What to expect afterward

Once you've submitted a request with any supporting evidence, an NDIA planner reviews it. NDIS guidance states they aim to let you know their decision within 21 days. There are three possible outcomes:

• No change — the current plan is considered to still meet the need
• A varied plan — an adjustment without a full reassessment
• A new plan — a full reassessment, looking again at goals, evidence, and how current supports are working

Processing steps and timeframes can change, so always check the current position on ndis.gov.au or with your NDIA contact rather than relying on any figure quoted here as fixed.

If you disagree with the outcome

If the decision that comes back isn't what you expected and you believe it's wrong, that's no longer a reassessment question — it moves into the formal review of a decision (appeals) process. That pathway, including timeframes and how to lodge a request, is covered separately in Your NDIS request was declined — reviews and appeals.
