NDIS Claiming Integrity Audit: The Step-by-Step Guide to Recovering $200K+ in Unclaimed Revenue

Most NDIS providers believe their claiming is accurate. Most are wrong. After conducting revenue recovery audits across dozens of NDIS providers at the $5M–$50M revenue scale, I have yet to find a single organisation that was not leaving material revenue on the table through a combination of pricing gaps, missed provisions, claiming errors, and under-utilised plan budgets.

The average revenue recovery from a systematic claiming integrity audit is $200,000–$500,000 per year for providers at this scale. That is not a projection — it is the median outcome from audits I have conducted. The money exists in your current participant base. The question is whether you have the systems and knowledge to collect it.

This guide provides the step-by-step claiming integrity audit framework that specialist NDIS CFOs use to identify and recover unclaimed revenue. It covers the five most common claiming gaps, the audit methodology, and the system changes required to prevent the leakage from recurring.

Why NDIS Claiming Integrity Is a CFO Priority

Claiming integrity is not just a compliance issue — it is a revenue issue. Every claiming error that results in under-payment is permanent revenue loss. Unlike AN-ACC reclassification in aged care, where historical under-funding can sometimes be recovered retrospectively, NDIS claiming gaps are generally not recoverable once the claiming window closes. The revenue is gone.

The NDIS claiming window — the period within which a claim must be submitted after service delivery — varies by support type but is typically 90 days for most supports. Claims submitted after this window are rejected. For providers with high volumes of low-value supports, the cumulative impact of missed claiming windows can be substantial.

Claiming integrity also has a compliance dimension. The NDIS Quality and Safeguards Commission treats over-claiming — claiming for services not delivered, or claiming at rates above the Price Guide maximum — as a serious compliance breach. A claiming integrity audit protects the organisation from both under-claiming (revenue loss) and over-claiming (compliance risk). For a comprehensive overview of NDIS audit preparation, see our guide to the NDIS Quality and Safeguards audit financial governance checklist.

The Five Most Common NDIS Claiming Gaps

1. Pricing Below the Price Guide Maximum

The NDIS Pricing Arrangements and Price Limits set the maximum amount providers can charge for each support item. Many providers — particularly those who set their prices at registration and have not reviewed them since — are charging below the current maximum. This is not a compliance issue; it is a revenue gap.

The most common cause is failure to update service agreements when the NDIS Pricing Arrangements are updated annually (typically in July). If your service agreements reference a price from the 2024-25 Pricing Arrangements and the 2026-27 arrangements have increased the maximum, you are under-charging every participant on that agreement. For a detailed analysis of the 2026-27 pricing changes and their financial implications, see our guide to NDIS Pricing Arrangements 2026-27.

The audit step: Extract every active service agreement and compare the agreed price for each support item against the current Price Guide maximum. Calculate the annual revenue gap for each participant and aggregate across your participant base. For a provider with 200 participants and an average under-pricing of $5 per support hour across 20 hours per week, the annual revenue gap is $1,040,000.

2. Missed Short-Notice Cancellation Fees

The NDIS Pricing Arrangements allow providers to claim a cancellation fee when a participant cancels a support with less than the required notice period (typically 2 business days for most supports, 5 business days for some specialist supports). Most providers know this provision exists. Most do not claim it consistently.

The reasons for under-claiming cancellation fees are typically operational rather than deliberate: support workers do not record cancellations in the system, coordinators do not flag short-notice cancellations for claiming, or the claiming process does not have a step for cancellation fee review. The result is that providers absorb the cost of cancelled supports without recovering the revenue the framework allows.

For a provider with 200 participants averaging one short-notice cancellation per participant per month at an average support rate of $65 per hour for a 2-hour support, the annual unclaimed cancellation revenue is $312,000. This is a conservative estimate — providers with higher participant volumes or higher support rates will have larger gaps. For a detailed framework on cancellation fee recovery, see our guide to NDIS cancellation fee recovery.

3. Claiming Errors and Rejections Not Followed Up

NDIS claim rejections are common. The NDIA rejects claims for a range of reasons: incorrect support item numbers, plan budget exhaustion, participant plan expiry, and documentation gaps. Most providers track their rejection rate — but many do not have a systematic process for investigating and resubmitting rejected claims.

A claim that is rejected and not resubmitted is permanent revenue loss. For providers with rejection rates above 3%, the cumulative impact of unresolved rejections can be significant. The audit step: Pull a 12-month rejection report from your claiming system. Categorise rejections by reason code. For each category, determine whether the rejection was valid (the claim was incorrect) or invalid (the claim was correct but rejected in error). For invalid rejections, resubmit within the claiming window. For valid rejections, identify the root cause and implement a process fix.

4. Under-Utilised Plan Budgets

Participants with unspent plan budgets at plan review are at risk of having their budgets reduced in the next plan. While providers are not responsible for participant plan utilisation, there is a legitimate role for providers in supporting participants to understand and use their funded supports. Participants who are not accessing their full entitlement are not receiving the support they need — and providers are not delivering the revenue their service agreements contemplate.

The audit step: For each participant, compare the supports delivered in the past quarter against the supports funded in their plan. Identify participants with significant under-utilisation (more than 20% of funded supports not delivered). Investigate the reason — is it participant choice, scheduling gaps, or a failure to offer the full range of funded supports? Where under-utilisation reflects a service delivery gap, address it.

5. Incorrect Support Item Codes

The NDIS support catalogue contains thousands of support items, each with a specific code, description, and price. Using the wrong support item code — even for a service that was legitimately delivered — can result in under-payment (if a lower-priced code is used) or a compliance risk (if a higher-priced code is used). Many providers use a limited set of support item codes and do not regularly review whether those codes accurately reflect the supports being delivered.

The audit step: Review a sample of claims across each support category and verify that the support item code used matches the support delivered. Pay particular attention to supports that have changed in nature over time — a support that began as standard assistance with daily activities may have evolved to include elements that qualify for a higher-priced support item code.

The Claiming Integrity Audit Methodology

A systematic claiming integrity audit follows a structured methodology that ensures all five gap categories are assessed and the revenue recovery opportunity is accurately quantified.

Phase 1: Data Extraction and Baseline (Week 1–2)

Extract 12 months of claiming data from your NDIS management system. This should include every claim submitted, the support item code, the amount claimed, the participant, the date of service, and the claim outcome (paid, rejected, or pending). Also extract your current service agreements for all active participants, including the agreed prices for each support type.

Phase 2: Gap Analysis (Week 2–3)

Compare your claimed prices against the current Price Guide maximums for each support item. Identify all short-notice cancellations in the period and determine which were claimed and which were not. Analyse rejection data by reason code and identify unresolved rejections. Review plan utilisation data for each participant.

Phase 3: Revenue Recovery Quantification (Week 3–4)

Quantify the annual revenue recovery opportunity for each gap category. This produces the dollar figure that justifies the investment in system and process improvements. For most providers, the quantification exercise alone is sufficient to secure board and management commitment to the recovery program.

Phase 4: System and Process Improvements (Month 2–3)

Implement the changes required to close each gap: update service agreements to current Price Guide maximums, implement a cancellation fee claiming process, establish a rejection follow-up workflow, and review support item code usage. These changes prevent the gaps from recurring and protect the recovered revenue on an ongoing basis.

Building a Claiming Integrity Register

The output of a claiming integrity audit is not just a one-time revenue recovery — it is the foundation for an ongoing claiming integrity register. This register documents your internal controls for ensuring that every claim submitted to the NDIA is accurate, supported by a service agreement, and matched to a delivered support.

A claiming integrity register should record: who reviews claims before submission, how often, what exceptions have been identified and resolved, and the results of quarterly internal claiming audits. This register is also a key document for NDIS Commission audits — it demonstrates that your organisation has proactive claiming governance, not just reactive error correction.

The Role of a Fractional CFO in Claiming Integrity

Most NDIS providers at the $5M–$30M revenue level do not have a CFO with the specialist knowledge to conduct a claiming integrity audit. Their finance manager handles day-to-day accounting, but lacks the NDIS pricing framework expertise to identify the gaps described in this guide. A generalist accountant or bookkeeper will not know that short-notice cancellation fees exist, let alone how to build a process to claim them consistently.

A specialist NDIS fractional CFO brings the pricing framework knowledge, the audit methodology, and the system design capability to conduct a claiming integrity audit and implement the changes required to close the gaps. For most providers, the revenue recovered in the first 60 days of a fractional CFO engagement exceeds the cost of the engagement for the entire year.
