How does NDIS plan-managed billing differ from self-managed for bookkeeping purposes?

Plan-managed clients are invoiced to the participant's plan manager, who pays on a set claim cycle, while self-managed clients pay the practice directly and claim reimbursement themselves. Agency-managed funding is claimed directly through the NDIA portal. Each pathway has a different payment timeline and reconciliation process that needs to be tracked separately in the practice's books.

Are speech pathology services GST-free?

Speech pathology services provided by a recognised professional are generally GST-free under the health services exemption in the GST Act, provided the service is generally accepted in that profession as necessary for the appropriate treatment of the client, but products sold alongside therapy, such as communication devices or resource materials, may be taxable and need to be identified separately.

What are Medicare CDM items and how do they apply to speech pathology?

Chronic Disease Management items allow a GP to refer a patient with a chronic condition to allied health services, including speech pathology, for a rebated number of visits per calendar year. Bookkeeping needs to track the rebate portion separate from any patient gap payment, since the two are usually processed through different payment channels.

How should group therapy sessions be billed and recorded differently from individual sessions?

Group sessions are typically billed at a lower per-participant rate than individual sessions and funded differently under NDIS line items, so revenue needs to be allocated per participant against the correct line item rather than recorded as a single lump sum for the group, to keep NDIS claims and reporting accurate.

Can telehealth speech pathology sessions be billed the same as in-person sessions?

Generally yes under NDIS and Medicare telehealth provisions, provided the session meets the relevant delivery requirements, but it's worth confirming current item eligibility for telehealth delivery each time billing rules are reviewed, since telehealth provisions have been adjusted more than once since being introduced.

Three Funding Pathways, Three Payment Timelines

A Melbourne speech pathology practice servicing NDIS participants usually deals with three distinct funding pathways at once, plan-managed, self-managed and agency-managed, and each one pays on a different timeline through a different process. Plan-managed clients are invoiced to a registered plan manager, who typically pays within a set claim cycle once the invoice is submitted. Self-managed clients pay the practice directly, generally the fastest of the three. Agency-managed funding is claimed directly through the NDIA's myplace portal against the participant's plan, and tends to have the most rigid claiming rules and the least flexibility if something is coded incorrectly. Bookkeeping that doesn't separate these three streams makes it very hard to answer a simple question: which of these is actually causing our debtor days to blow out?

GST Treatment: Mostly Free, With Exceptions

Speech pathology treatment provided by a recognised professional is generally GST-free under the health services exemption in the GST Act, where the service is one generally accepted in the profession as necessary for the appropriate treatment of the client. Where this gets missed is on the retail side, communication devices, resource packs, workbooks or take-home materials sold alongside therapy are often taxable supplies, not GST-free health services, and a practice that lumps device sales in with therapy income on its BAS is very likely under-reporting GST it actually owes.

Medicare CDM Items and the Gap Payment Split

Chronic Disease Management referrals let a GP refer a patient with a chronic condition to a rebated allocation of allied health visits per calendar year, including speech pathology. The rebate is paid through Medicare, while any gap between the rebate and the practice's fee is collected directly from the client, two separate payment channels for a single session, and bookkeeping needs to reconcile both against the one appointment rather than recording a single blended fee that obscures which portion came from Medicare and which was a client gap payment.

Compliance: Registration and Reporting Obligations

NDIS-registered providers carry reporting and audit obligations under the NDIS Practice Standards that go beyond simply invoicing correctly, claims need to be traceable back to the specific supports delivered and the participant's plan, and a practice that can't quickly produce that trail during an NDIS audit risks having claims disputed or funding paused. Keeping session notes, billing codes and payment records properly linked at the time of billing, rather than reconstructed later, is the difference between an audit being routine and an audit being a genuine problem.

KPIs Speech Pathology Practices Should Track

Revenue by funding pathway, plan-managed, self-managed, agency-managed and Medicare, tracked separately.
Debtor days by pathway, plan manager payment delays are the most common cause of a blown-out average.
Utilisation per clinician, billable session hours against total available hours.
Group vs individual session revenue split, since the two are billed and funded at different rates.
