What happens if the insurer denies my CTP claim in NSW?

Short answer: read the insurer's reasons, check the review deadline in the notice, collect evidence that responds to each reason, and request the correct review or dispute pathway. Many NSW CTP claim denials first go to internal review. If the decision is not changed, the next step may be a Personal Injury Commission (PIC) pathway such as merit review or medical assessment.

• Liability denial: match the insurer's reasons against police, accident, witness, treatment, and claim-form evidence.
• Weekly payment or PAWE dispute: gather payslips, tax records, rosters, overtime records, and business income evidence where relevant. See the PAWE calculation guide.
• Treatment refusal: ask the treating doctor to address why the treatment is accident-related and reasonably necessary. See treatment refused in NSW CTP.
• Threshold injury or WPI dispute: focus on the medical criteria, imaging, specialist opinions, and the reasons the insurer relied on.

When you compare the denial with similar decisions, use the NSW CTP case law and PIC decisions archive as an issue map: match the insurer reason to threshold injury, WPI, PAWE, treatment refusal, fault, or nominal defendant evidence before drafting submissions.

This page is general information only. It does not guarantee that a denial can be overturned, and time limits should be checked against your actual decision notice.

This route is the dispute hub, not a replacement for issue-specific pages. Use it to identify the insurer decision, then move to the page that matches the actual reason for denial or reduction.

• Liability, fault or accident circumstances: start with the insurer notice, police/event material, witness accounts, treatment chronology and any Nominal Defendant or interstate-vehicle issue.
• Weekly payments or PAWE: compare the decision with payslips, tax records, rosters, overtime, business records and certificates of fitness before using the PAWE route.
• Treatment refusal: ask the treating practitioner to address accident causation, reasonable necessity, clinical alternatives and why delay may affect recovery.
• Threshold injury, WPI or capacity: separate medical classification evidence from work-capacity evidence, because the PIC pathway and assessor questions can differ.

Official source trail: check the current SIRA motor accident guidance and the Personal Injury Commission pathway for the decision type before lodging. This page was reviewed as general information for NSW CTP disputes and should be read with the actual insurer notice, because deadlines and procedural steps can turn on the exact decision.

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.

Deadline warning: Internal Review time limits depend on the decision type, decision letter wording, and applicable rule. 28 days is common in many disputes, but it is not universal. Always follow the deadline in your notice.

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).

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.

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.

Insurers often rely on a short surveillance clip, a single gym visit, or one successful return-to-work shift to argue that your capacity has substantially improved. In practice, those snapshots rarely prove durable work capacity.

PIC decision-makers usually want to see whether function is sustainable over time, not whether you can push through pain once. The key question is reliability across ordinary weeks, including symptom flare-ups and recovery lag.

• Track consistency: Keep a 4–6 week log showing what you could do on good days, bad days, and the day after activity.
• Show delayed effects: Record later-day pain escalation, medication use, disrupted sleep, and next-day loss of function after exertion.
• Use workplace corroboration: Ask supervisors or return-to-work coordinators to document pacing breaks, reduced duties, and failed progression attempts.
• Link to medical evidence: Treating-doctor and specialist reports should explain why one-off performance is not medically predictive of sustained capacity.

If the insurer is over-reading a single event, frame your response around reliability, repeatability, and recovery cost. That structure is usually more persuasive than arguing only from pain severity.

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.

Some disputes sit inside more complex family-loss and psychiatric-injury scenarios. If the accident was fatal, separate funeral-expense, dependency, and psychiatric-injury issues may need different evidence streams even though they can intersect in the same matter. See CTP death claims, compensation to relatives, and secondary victim psychiatric injury.

You can represent yourself, but CTP disputes are technical and can involve medical definitions, statutory wording, insurer reasons, review steps, and Personal Injury Commission evidence rules.

If a decision letter has stopped payments, refused treatment, classified an injury as threshold, or raised a PIC filing step, use the CTP claim lawyers NSW guide to check what a lawyer should review first: the decision date, the stated reasons, current medical evidence, wage records, and any review deadline. The first assessment should identify the pathway and evidence gaps without promising an outcome.

When you are ready to send documents, use the NSW CTP contact page with the insurer letter, claim number, certificates of capacity, PAWE material and any PIC or internal-review paperwork.

No Win, No Fee: Some CTP dispute matters may be handled on a conditional fee basis where eligible. Costs and any insurer contribution depend on the dispute type, outcome, and applicable rules, so they should be checked against the particular matter.
