How old can evidence be?

The NDIS generally prefers evidence that is no more than two years old, though for stable conditions, older evidence combined with a more recent clinical letter confirming continued impact may be accepted.

Can a GP write the supporting evidence?

A GP can contribute evidence, particularly for confirming a diagnosis, but for functional assessments the NDIS prefers reports from specialists or allied health professionals with expertise in the relevant domain.

Do I need to pay for assessments?

Allied health assessments for an access request are not covered by NDIS before you have a plan. They may be covered by Medicare, private health insurance, or state government schemes. Your GP can provide referrals for Medicare-rebated assessments.

What is the difference between disability requirements and early intervention requirements?

Disability requirements apply to people with established disability where the focus is on current functional impact. Early intervention applies where supports are likely to reduce the future impact of a newly diagnosed or developmental condition.

Can I submit more evidence after lodging the request?

Yes. You can submit additional evidence while the request is being assessed. Contact the NDIS to ensure the additional documents are linked to your access request.
