This question comes up constantly, in different shapes: "Does my son having private health insurance affect his NDIS plan?" "Now that we're on the NDIS, can we drop our health insurance?" "The hospital says it's an NDIS matter, the planner says it's a health matter — who's right?"
The honest answer is that these are two completely separate systems, built for different purposes, assessed against different criteria. Once that separation is clear, most of the confusion falls away. This article sets out what's actually confirmed by official sources, and is upfront about the couple of places where you genuinely need to check your own circumstances rather than take a general answer.
The NDIS funds reasonable and necessary supports connected to a person's disability — things that help someone manage or reduce the day-to-day impact of a permanent, significant impairment. It is not a general health scheme. The NDIS itself is explicit about this boundary. On its page explaining disability-related health supports, the NDIS states plainly: "We can't fund services and supports that you can get through the health system and other community and mainstream supports and services."
Medicare, the public hospital system, and the Pharmaceutical Benefits Scheme (PBS) remain the primary system for healthcare in Australia — for everyone, including NDIS participants. That means:
The NDIS sits alongside this system for the specific, narrower category of supports that exist because of a person's disability — things like assistive technology, home modifications for accessibility, disability-related continence or wound care supplies, capacity-building therapy tied to disability goals, and support workers. There's more detail on how that funding is actually structured in our guide to NDIS budget categories explained.
"The NDIS and the health system are not competing for the same job. One treats and manages health conditions. The other funds supports connected to a permanent disability. Most confusion disappears once you separate those two questions."
It's an understandable confusion, for a few reasons. First, both systems can be involved in the same person's life at the same time — someone with a permanent disability still gets sick, still needs a GP, still might need surgery, exactly like anyone else. Second, some items genuinely can sit in either system depending on why they're needed, which we'll walk through below. Third, the language used across government websites — "supports," "services," "health," "care" — overlaps enough that it's easy to assume one big system is making all the decisions, when in fact two entirely separate sets of rules are operating side by side.
None of this is a design flaw specific to families managing a plan — even service providers and clinicians sometimes have to check the interface rules before they're sure which system pays. It's genuinely a known area of complexity, which is exactly why a formal agreement between governments (below) exists to try to settle it.
No — and this is worth stating clearly because it's one of the most common worries families raise. According to the NDIS's own published access criteria, whether someone can become an NDIS participant depends on:
Private health insurance status does not appear anywhere in those criteria. Income and assets are also not part of NDIS eligibility testing — the NDIS is not means-tested the way some other schemes are. Whether a family holds private hospital cover, extras cover, or no cover at all has no bearing on whether the person they care for can access the NDIS, or on how much funding is included in their plan. Plan funding is based on an individual assessment of reasonable and necessary support needs, not on the household's insurance arrangements.
In plain terms: you do not need to drop private health insurance to "qualify" for the NDIS, and you do not need to take it out to protect NDIS eligibility either. The two decisions are unrelated.
Not on the basis of NDIS participation alone. Because the NDIS does not fund general medical treatment, hospital admissions, or surgery, having an NDIS plan doesn't reduce your family's need for Medicare or private health cover for those things. If the person you care for needs surgery unrelated to their disability, that's a health system and (if applicable) private health insurance matter — the NDIS plan doesn't step in to cover it.
Whether to hold private health insurance at all is a genuinely personal financial decision that depends on your income, the Medicare Levy Surcharge (below), waiting times in your area, and what cover you actually want. That decision should be made on its own terms — not as something the NDIS changes.
There is a real, named framework that governments use to work out which system — NDIS or health — is responsible for a particular support where there could be some overlap. It's called the Applied Principles and Tables of Support (APTOS), agreed between the Australian, state and territory governments. Its stated purpose is to help "determine the funding and delivery responsibilities of the NDIS" as against other service systems, including health.
You won't usually need to read APTOS itself — it's a policy-level document, not something written for families. What matters practically is the principle it reflects, which the NDIS restates in more accessible terms on its own site: general healthcare stays with the health system, and the NDIS funds the disability-specific layer on top of that. The NDIS's own operational guideline on disability-related health supports is the most useful practical reference if you want to check whether something is likely to be an NDIS matter — see the source list below.
This is where the interface actually becomes visible in someone's life, so it's worth walking through directly.
The distinguishing question is never "which system is more generous" or "which would I rather use." It's: is this support needed because of a permanent disability, or because of a temporary or unrelated health event? The same logic applies to other equipment and aids — hospital beds, pressure care items, communication devices, and so on. The reason for the need determines the funding pathway, not the item itself.
The wheelchair example is the clearest one, but the same "why is this needed" test comes up across a lot of everyday situations families deal with:
You don't need to memorise this list — the underlying test is always the same one described above. If in doubt, treat it as a question to ask, not an assumption to make either way.
A quick self-check before you assume either way: ask yourself (1) is this need connected to a permanent, ongoing disability, or is it temporary and would resolve on its own? (2) would a person without that disability need the same thing for the same reason? (3) has this specific item or service actually been discussed and assessed in the person's NDIS plan, or am I assuming it's covered? If you're unsure on any of these, that's the moment to ask your planner or treating professional directly, rather than guess.
The Medicare Levy Surcharge (MLS) is a separate tax matter from all of the above, and it's worth being precise about it because it involves real money.
According to privatehealth.gov.au (the Australian Government's official private health information site), the MLS is an additional levy — on top of the standard 2% Medicare levy — charged to higher-income taxpayers who do not hold approved private hospital cover. It exists to encourage people who can afford it to take up private hospital insurance and reduce pressure on the public system. It's based on income thresholds and whether you (and your dependants) hold private hospital cover — nothing else.
We checked specifically for any NDIS-related exemption or adjustment to the MLS and found none stated in official sources. Being an NDIS participant, or caring for one, is not described anywhere in the official MLS guidance as affecting the surcharge. If your family's situation is financially complex — for example, if you're weighing up dropping private hospital cover while also managing NDIS-related costs — the right move is to check your own numbers with the ATO or a registered tax agent, not to assume disability or NDIS status changes the calculation.
One genuinely useful, free tool here: AskMyGP's Medicare Levy Surcharge Calculator lets you estimate whether you're likely to be affected, based on your income and cover — a helpful starting point before you talk to a tax professional.
A separate, older point of confusion: in 2013, the standard Medicare levy paid by most Australian taxpayers was permanently raised from 1.5% to 2%, with the increase linked to national NDIS funding. A further proposed rise was later dropped by government. This is a general, national tax settled at a whole-of-country level — it is not personalised to whether you or your family member is an NDIS participant, and it's a completely different thing from the Medicare Levy Surcharge described above. Don't let the similar name cause confusion between the two.
Some situations sit right on the line, and no general article can resolve them for your specific circumstances. When that happens:
A practical way this plays out: a family caring for a teenager with cerebral palsy might be told by a hospital discharge team that a particular seating system is "an NDIS thing," while their LAC says it needs a health assessment first because it was requested during a hospital admission. Neither answer is necessarily wrong — it usually means the specific item needs to be looked at against both sets of rules before anyone commits funding, and that's normal, not a sign that something has gone wrong with the plan. Asking both sides directly, and asking them to talk to each other if needed, is a completely reasonable thing to request.
If you're still preparing for a planning meeting or working out how to frame a request, our guide to the NDIS access request process and the full NDIS Guide Hub are good next stops.
None of this is medical, legal, tax or financial advice — it's a plain-language map of how two real, separate systems relate to each other, drawn from official sources, so you can ask better questions when you talk to the people who make the actual decisions.
Last reviewed: August 2026. This article explains general principles only — no dollar thresholds for the Medicare Levy Surcharge are stated because they change and vary by circumstance. Always verify current income thresholds at privatehealth.gov.au or ato.gov.au, and confirm any specific support's funding pathway with your NDIS planner or LAC and your treating health professional. This is general information only, not medical, legal, tax or financial advice.
