CTP claim disputes in NSW — internal reviews and the PIC pathway

The NSW CTP scheme is adversarial. Insurers frequently issue decisions to deny liability, stop weekly payments, or classify injuries as "threshold" (minor) to limit their long-term costs. If you have received a denial letter or a notice of benefit reduction, you have legal rights to challenge that decision. This guide details the formal dispute pathways under the Motor Accident Injuries Act 2017.

1) The Section 7.10 Internal Review (The First Hurdle)

Before you can escalate most disputes to the Personal Injury Commission (PIC), you must first request an Internal Review from the insurer under Section 7.10 of the Act.

The 28-Day Deadline: You generally only have 28 days from the date you receive the insurer's decision to request an internal review. If you miss this window, the insurer is not required to review their decision, and you may lose your right to further appeal.

What happens during review? A person within the insurance company who was not involved in the original decision will review the evidence. They can either: 1) "Affirm" the decision (keep it the same), 2) "Vary" the decision, or 3) "Set aside" the decision (replace it with a new one).

2) Merit Review vs. Medical Assessment

In the NSW CTP scheme, disputes are broadly split into two categories. Knowing which one your dispute falls into determines your legal strategy.

Merit Review Matters

These involve disputes over the "merit" of a decision, such as:

The calculation of your average earnings (PAWE).
Whether an insurer is required to pay for a specific travel expense.
Whether you have provided the correct documents.

Medical Assessment Matters

These are the most high-stakes disputes and involve medical evidence, such as:

Threshold Injury Classification: Is your injury soft-tissue only, or is there radiculopathy?
Whole Person Impairment (WPI): Is your permanent impairment greater than 10%?
Treatment Necessity: Is that surgery or MRI "reasonably necessary"?

For injury-specific dispute context, see major depressive disorder after a crash and severe burns claims.

3) Common Insurer Tactics in Disputes

Insurers have significant resources and use them to limit their liability. Common tactics include:

Selection of IMEs: Using "Independent Medical Examiners" who have a history of providing conservative assessments that favor the insurer.
Surveillance: Hiring private investigators to film you in public places to challenge your "capacity for work" or level of pain.
Post-52 Week Liability Notices: Issuing a liability/benefits decision around the 52-week point that triggers urgent dispute steps when claimants are most vulnerable.
PAWE Errors: Excluding overtime or bonuses from your weekly payment calculation, hoping you won't check the math.

4) The Personal Injury Commission (PIC) Pathway

If the Internal Review is unsuccessful, the next step is the Personal Injury Commission (PIC). The PIC is the independent body that makes final, binding determinations on CTP disputes.

Application: We lodge a formal application for resolution, including all medical and financial evidence.
Member or Assessor: A "Member" handles legal/merit disputes, while a "Medical Assessor" (a specialist doctor) handles injury classification and WPI disputes.
Certificate of Determination: The PIC issues a formal certificate that the insurer MUST follow.

5) Do you need a lawyer for a dispute?

While you can represent yourself, the insurer will always be represented by specialized litigation lawyers. CTP disputes are highly technical, involving complex medical definitions and legislative interpretations.

No Win, No Fee: Most CTP dispute matters are handled on a "No Win, No Fee" basis. For statutory benefit disputes (like weekly payments and treatment), the insurer is often required to pay a contribution toward your legal costs if you are successful, making expert representation accessible.

Frequently asked questions

What is a post-52 week liability notice in NSW CTP?: It is an insurer liability/benefits decision issued around the 52-week stage that can affect ongoing statutory benefits. It should clearly set out reasons, the evidence relied on, and your dispute/review pathway.
How long does a CTP dispute take to resolve?: An Internal Review must be completed within 14 to 21 days. If the matter goes to the Personal Injury Commission, it typically takes 3 to 6 months to reach a final determination, depending on the complexity of the medical evidence.
Can I dispute a "Threshold Injury" classification?: Yes. This is one of the most commonly disputed matters. We often challenge these decisions by obtaining a report from a highly qualified specialist who can identify "non-threshold" signs like radiculopathy or a recognised psychiatric illness.
What if I miss the 28-day deadline for Internal Review?: If you miss the deadline, you must provide a reason for the delay. The insurer can refuse to conduct the review if they believe the delay is not justified. This is why acting immediately after receiving a denial is critical.
Can the PIC force the insurer to pay for surgery?: Yes. If a Medical Assessor at the PIC determines that the surgery is "reasonably necessary" and related to the accident, they will issue a Certificate that legally compels the insurer to fund the treatment.
Is a PIC Medical Assessment like a normal check-up?: No. It is a forensic medical examination. The Assessor is not there to treat you; they are there to answer specific legal questions about your injury classification or impairment percentage under the SIRA Guidelines.
Can the insurer conduct surveillance on me?: Yes, insurers frequently use surveillance if they suspect a claimant is exaggerating their injuries. It is legal for them to film you in public places (like the street or a park). If you are in a dispute, you should assume surveillance may be active.
What is a "Certificate of Determination"?: This is the final written decision issued by a Member of the Personal Injury Commission. It is a legally binding document that sets out the PIC’s ruling on your dispute.
