Allied health in an NDIS practice: what the admin has to do differently

This is for practice managers and finance officers running a mixed caseload — occupational therapists, speech pathologists, dietitians, exercise physiologists, physios — billing against NDIS plans. You’ll get a plain look at the 2026-27 pricing change that catches a lot of practices out, plus how travel, reports and non-face-to-face time are meant to be claimed.

For years, a lot of allied health billing leaned on a catch-all line — something like “Therapy — Other Professional” — because it was close enough and nobody had to think too hard about which discipline-specific code applied. Under the 2026-27 price limits, that catch-all line fell by around 19.5%. If your invoicing still defaults to it, you’re now claiming under the old assumption at a lower cap, or claiming at a rate the NDIA will knock back.

At the same time, the caps moved in different directions by discipline. Dietetics and exercise physiology caps fell. Support-worker bands, by contrast, rose. A practice that treats “allied health” as one bucket — one price book, one set of defaults — can be over-claiming on some lines and under-claiming on others without anyone noticing, because the invoice total looks roughly right even when the individual lines are wrong.

The fix isn’t complicated, but it does require deliberate setup: price every discipline against its own current limit, not a historical shortcut. We’ve written up the full 2026-27 schedule separately — worth reading alongside this if you haven’t checked your price book against it yet.

The practical danger here isn’t a dramatic compliance breach. It’s slow leakage. A speech pathologist’s session gets billed under the old catch-all because that’s what the template defaulted to in March. Nobody catches it because the invoice still gets paid — until it doesn’t, or until a plan reviewer asks why a line item doesn’t match the registered item number for that discipline.

This is where knowing what was actually paid, not just what was claimed, matters. If your system only shows you the claim file you submitted, a wrong item code or an over-cap line can sit unnoticed for months. Reading the NDIA’s own payment outcome back — paid, part-paid, rejected, with the NDIA’s own reason — turns that into something you can act on immediately rather than discover at audit time. To be clear about how that actually works: the claim file still goes to the provider portal by hand, there’s no direct submission happening automatically, this is about reading what comes back once you’ve uploaded it.

Two categories trip up allied health billing more than anything else:

Travel. NDIS pricing allows claiming for a clinician’s travel time under specific rules, but it has to be recorded against the shift, not estimated at invoice time. If your roster system captures paid travel time on the shift itself, as it happens, you’ve got a defensible record. If travel is reconstructed from memory at the end of the fortnight, you’re guessing, and guesses are the first thing a plan reviewer queries.

Non-face-to-face time. Report writing, liaison with a GP or support coordinator, case conferencing — these are legitimately billable in many circumstances, but only against the right item and only if there’s a record of what was actually done. “I spent an hour on this client’s file” isn’t a line item; “45 minutes drafting the home modification report, 15 minutes liaising with the OT’s supervisor” is defensible, because it maps to something specific.

The administrative discipline here is the same for both: capture the activity at the point it happens, against the shift or the client record, rather than reconstructing it from memory when invoices are due.

Allied health practices often under-claim for the thing that actually takes the most clinical time: the report. An assessment report, a progress report, a home modification recommendation — these take hours, and they’re billable under the right item, but only if the practice treats the report as a deliverable with its own time record, not something squeezed in after hours and absorbed into overheads.

If your practice generates these as structured documents — a support plan, a risk assessment, an outcome or progress report — attaching the time spent to the document itself, rather than guessing at invoice time, gives you both a defensible audit trail and a more accurate invoice. The report stops being invisible labour and starts being counted.

Plenty of allied health practices also run support work — assistants, community access staff, or they’re part of a broader provider that does both. The administrative trap is pricing these two streams inconsistently: therapy items get updated when the new schedule lands, support worker items get updated separately (or not at all), and the two streams drift apart.

The safer approach is one price book, with every item — therapy, by discipline, and support work, by SCHADS-style band — checked against the same current national limits. When dietetics caps fall and support-worker bands rise in the same update, you want both changes landing in the same place at the same time, not one team remembering and the other finding out three invoice runs later.

This matters more for budget tracking than people expect. A client on a plan with both therapy and support hours needs a single view of utilisation across both, with bars showing what’s left, not two spreadsheets that have to be reconciled by hand before anyone can answer “how much of this plan is left.”

Pulling this together, the practices that don’t leak revenue (or over-claim without knowing) tend to do a few unglamorous things consistently:

• Price every discipline against the current limit, not last year’s, and don’t lean on a catch-all item as a default.
• Record travel time on the shift, not from memory at invoice time.
• Log non-face-to-face work — reports, liaison, case conferencing — against the specific activity, so it’s claimable under the right item rather than absorbed as unpaid overhead.
• Keep therapy and support-work pricing in the same book, updated together, so a plan with both doesn’t drift out of sync.
• Check what was actually paid against what was claimed, line by line, so a wrong code gets caught in weeks, not at the next plan review.

None of this needs to be dramatic. It needs to be consistent, and it needs the pricing to be current.

Corella’s price book holds per-band NDIS items checked against the 2026-27 national limits, with travel time recorded on the shift itself and client budgets showing utilisation across therapy and support work in one view. It reads back the NDIA’s payment outcomes line by line, so a wrong item code shows up as a rejection you can act on, not a mystery in next quarter’s revenue. It doesn’t submit claims directly to the NDIA — you still generate and upload the bulk file yourself — and it won’t tell you which item code is clinically correct for a given service; that judgement stays with your practice.
