reasonable-and-necessary

Under the NDIS framework, "Reasonable and Necessary" refers to the strict legal criteria the NDIA must be satisfied with before approving funding for any support. This concept is critical to NDIS support coordinators because they act as the architects of a participant's support ecosystem and must gather the exact evidence required to justify funding across all support categories.

If a coordinator fails to clearly document how a requested support meets these criteria — such as proving it represents value for money or demonstrating that informal and mainstream systems cannot provide the care — the NDIA is legally obligated to reject the funding request. The Participant Statement Toolkit is fundamentally engineered to construct a robust case that satisfies the "reasonable and necessary" test. Block 1 (Environmental and Personal Context) captures the exact information needed to address sections 34(1)(e) and (f), while the Support Coordinator Translation Matrix provides the direct legislative justification for value for money and evidence of effectiveness.

RS-04 research reinforces a critical principle for practitioners: the "reasonable and necessary" test must be the primary foundation of any funding request — not internal accounting logic such as item code mapping or cost-benefit analysis. While technical knowledge of item code anatomy is useful as a secondary tool, approaching the Participant Statement primarily as an accounting exercise conflates the NDIA's internal pricing system with its actual legal decision-making framework. NDIA planners assess requests against statutory criteria — not spreadsheet inputs. A statement grounded in Section 34 criteria creates a clear evidentiary chain that makes the planner's job easier and positions the participant's rights as the starting point, not the conclusion.

NDIA delegates assess support justifications by cross-referencing requested items against the criteria in Section 34(1) and the NDIA Operational Guidelines. Following Administrative Appeals Tribunal (AAT) precedents, delegates look closely at the history of a participant's progress to determine if ongoing funding for a specific therapy is truly effective and beneficial. Delegates are audited by the Australian National Audit Office (ANAO) to ensure they consistently apply value for money criteria, which means value for money justifications face external scrutiny beyond the individual planner.
