Why these two supports need an OT assessment first
The NDIA doesn't fund home modifications or higher-cost assistive technology (AT) on request alone. Before approving the work or the equipment, it needs evidence that the item or modification is directly linked to your disability-related needs and that it's the most appropriate and cost-effective way to meet them. That evidence comes from a formal OT assessment and report.
This means the assessment itself is a distinct piece of work from the modification or equipment it leads to — and it's usually the step that determines whether a request is approved and how quickly.
Home modifications: what's assessed
A home modification assessment looks at how you move through and use your home and identifies where the physical environment is creating a barrier to your independence or safety. This typically covers:
Minor modifications
Grab rails, ramps, lever taps, raised toilet seats — lower-cost changes that don't usually need structural work or council approval.
Major modifications
Bathroom redesigns, widened doorways, stair lifts — structural changes that typically involve a builder and a detailed scope of works alongside the OT report.
For major modifications, the OT usually works alongside a builder to cost and scope the work and the resulting report includes drawings or specifications the NDIA can assess against.
Assistive technology: what's assessed
AT assessments cover a much wider range — from everyday aids through to complex equipment. The NDIA groups AT into cost tiers and the assessment requirement scales with the cost and complexity of the item:
- Low cost (under $1,500): often doesn't require a formal OT assessment — items like shower chairs or jar openers can sometimes be self-directed
- Mid and high cost: requires an OT assessment and report — wheelchairs, powered mobility equipment, communication devices, environmental control systems
- Complex or custom equipment: often requires a trial period before the NDIA will fund the final item, so the person can confirm it actually meets their needs
Important distinction: the OT's assessment and report is funded from your Capacity Building budget. The equipment or modification itself is funded separately, usually from Capital Supports. The two are billed and approved differently, even though they're part of the same process.
What happens during the assessment
- Initial discussion — the OT talks through what's difficult in your daily routine and what you're hoping to achieve
- Home visit — the assessment is usually conducted in your home or wherever the modification or equipment will be used
- Trial (for AT) — where relevant, you trial equipment options before a final recommendation is made
- Report writing — the OT documents the assessment, the options considered and the clinical rationale for the recommended modification or equipment
- Submission — the report goes to your support coordinator, plan manager or directly to the NDIA depending on how your plan is managed
Book an OT home modification or AT assessment
Exercare provides occupational therapy assessments and reports for NDIS participants across south-east and eastern Melbourne, including home modifications and assistive technology.
How long does the process take?
The assessment itself is usually one to two hours. Report writing typically takes longer than the visit, especially for major home modifications where drawings or builder quotes are involved. Once submitted, NDIA approval timeframes vary — simple, well-evidenced requests move faster than complex ones, which is part of why a thorough, clearly written report matters.

Frequently asked questions
Do I need a referral for a home modification or AT assessment?
No. You need relevant funding in your NDIS plan — typically Capacity Building (Category 15) for the assessment itself, with the modification or equipment funded from Capital Supports or Home Modifications (Category 06). No GP referral is required.
Can I request a specific product or brand?
You can express a preference, but the OT's recommendation needs to be based on your assessed needs and represent value for money. The NDIA generally funds the most cost-effective option that meets those needs.
What if my needs change after the modification or equipment is approved?
A new or updated OT assessment can support a request to review your supports if your circumstances change significantly.
