Frequently asked questions
When does the NDIS 90-day claim window start?
It applies to supports delivered on or after 1 December 2026, replacing the previous two-year claim period. Supports delivered before that date keep their existing window. Confirm the commencement date against health.gov.au/securingtheNDIS and the current PAPL, as it depends on the reform legislation and rules being finalised.
Does the 90 days count from the service date or the invoice date?
From the date the support was delivered, not the date you raise the invoice or the date a plan manager pays you. Each service note carries its own 90-day deadline, so batching several weeks of work together sets the whole claim to the oldest, tightest date.
What happens if I miss the 90-day window?
The payment request is rejected and there is no ordinary way to recover that amount from the participant's plan — the delivered work is written off as a loss to your practice. This is why a fortnightly billing cycle with an internal 30-day hard stop matters, so no claim ever drifts close to the wall.
Does the 90-day rule affect plan-managed claims differently?
The rule is the same, but the risk is higher because your invoice passes through the plan manager before it is claimed. Their processing time counts against your 90 days, not theirs, so send invoices immediately, confirm receipt and chase within days if a claim stalls.
Does the shorter claim window change my support coordination rate?
No. The Level 1, 2 and 3 price limits are unchanged by this rule and remain frozen for a seventh year (indicatively around $80.06, $100.14 and $190.54 per hour as at the 2026-27 PAPL — confirm the current figures). The 90-day window only changes how quickly you must convert delivered work into a paid claim.
