How the 10% Impairment Threshold Affects Funding for Treatment Costs in NSW CTP Claims

The 10% whole person impairment threshold under NSW CTP laws determines whether treatment costs are funded. If your injury meets or exceeds this threshold, you may access ongoing medical funding. If not, benefits may be limited after 52 weeks. In Armidale, medical evidence is crucial to support your claim.

Current as at 4 October 2026

Under New South Wales' Compulsory Third Party (CTP) motor accident laws, the 10% whole person impairment threshold determines whether treatment costs are funded by the injured party's claim. This threshold is central to assessing whether a person is eligible for ongoing financial support for medical care. If your injury meets or exceeds this threshold, you may access funding for treatment costs. If not, certain benefits may be limited or discontinued after 52 weeks. This article explains how the threshold applies to treatment funding in Armidale, what evidence matters, and when to seek legal advice.

What is the 10% Impairment Threshold?

The 10% threshold is a legal benchmark set by the Motor Accident Injuries Act 2017. It refers to the level of permanent impairment a person must have to qualify for certain benefits under the CTP scheme. A whole person impairment assessment by a medical practitioner is required to determine whether this threshold has been met. This assessment considers the impact of the injury on the person's physical, mental, or psychological functions. For example, a broken leg that heals without long-term effects may not meet the threshold, while a spinal injury causing chronic pain might.

How Does the Threshold Affect Funding for Treatment Costs?

If your injury meets or exceeds the 10% threshold, the CTP insurer must fund your treatment costs. This includes medical consultations, scans, physiotherapy, and other necessary care. However, if your injury is below the threshold, you may only receive funding for treatment costs for the first 52 weeks after the accident. After this period, certain benefits like weekly income payments may stop, but treatment costs may still be funded depending on the nature of the injury.

The distinction is crucial. For instance, a person with a soft tissue injury (like a whiplash) that does not meet the threshold may only receive limited support for treatment. In contrast, someone with a significant injury that meets the threshold may access ongoing funding for medical care. The SIRA (State Insurance Regulatory Authority) guidelines provide detailed criteria for assessing impairment and determining eligibility for treatment costs.

What Evidence Matters for Treatment Funding?

To establish whether your injury meets the threshold and qualifies for treatment funding, you must provide:

  • A medical report from a registered medical practitioner confirming the impairment level.
  • Evidence of the injury's impact on your daily life, such as reduced mobility or chronic pain.
  • Documentation of treatment costs incurred, including receipts and invoices.
  • Any correspondence with the CTP insurer regarding your claim.

In Armidale, local medical practitioners and SIRA-approved assessors will evaluate your case. It is essential to ensure that your medical records clearly link your injury to the treatment costs you are seeking to fund.

Practical Steps for Claimants in Armidale

If you have suffered a motor accident in Armidale and are seeking treatment funding, take the following steps:

  1. Seek immediate medical attention and ensure all treatment is documented.
  2. Obtain a whole person impairment assessment from a medical practitioner.
  3. Contact the CTP insurer to report your claim and provide evidence of your injury.
  4. Keep copies of all medical records, treatment invoices, and correspondence.
  5. If your claim is denied or disputed, consider seeking independent legal advice to review your options.

Time Limits and Dispute Options

Under NSW CTP laws, there are time limits for claiming treatment costs. For injuries below the 10% threshold, weekly benefits typically stop after 52 weeks, but treatment costs may still be funded. If you believe your claim has been unfairly denied, you may need to challenge the decision. This could involve lodging a review with SIRA or seeking legal assistance to dispute the insurer's assessment of your impairment.

When to Seek Legal Advice

If your injury is complex, or if you are unsure whether you meet the 10% threshold, it is important to consult a legal professional. A solicitor can help you understand your rights, ensure your claim is properly prepared, and challenge any decisions that may affect your access to treatment funding. Legal advice is particularly valuable if your claim involves disputes over the impairment assessment or the insurer's refusal to fund treatment costs.

The 10% whole person impairment threshold is a key factor in determining whether treatment costs are funded under NSW CTP claims. If your injury meets or exceeds this threshold, you may access ongoing financial support for medical care. If not, certain benefits may be limited after 52 weeks. In Armidale, it is essential to gather strong medical evidence and understand your rights under the CTP scheme.
