How CTP Treatment Funding Works in NSW

Under New South Wales law, treatment costs for motor accident injuries are funded through the Compulsory Third Party (CTP) scheme. The Motor Accident Injuries Act 2017 (MAIA) ensures injured parties receive necessary medical care, including treatment, therapy, and rehabilitation. Funding is determined by the Motor Accident Guidelines and administered by the State Insurance Regulatory Authority (SIRA). If a treatment provider disputes funding, the dispute must be resolved through the CTP process, not private negotiation.

Common Funding Disputes and SIRA's Role

Insurers may deny or limit funding for treatment if they dispute the necessity, cost, or type of care. This often happens when:

  • The treatment is not listed in the
  • Motor Accident Guidelines*
  • The provider charges more than the scheduled fee
  • The injury is classified as a 'threshold injury' (minor soft tissue damage)
  • The treatment occurs outside the 52-week statutory benefit period

SIRA's What You Can Claim page explains that funded treatment must be:

  • Provided by a registered medical practitioner
  • Directly related to the accident
  • Reasonable in cost and scope

Practical Steps for Regional Claimants

In regional NSW, resolving treatment disputes requires understanding both legal and logistical challenges. Key steps include:

1. Documenting Treatment Costs

Keep detailed records of all treatment costs, including:

  • Itemized invoices from registered providers
  • Treatment summaries and clinical notes
  • Correspondence with insurers

2. Understanding the 52-Week Limit

Under s 4.4 of the MAIA, weekly benefits and treatment costs are generally limited after 52 weeks if the injury is a threshold injury. If your treatment exceeds this period, you must demonstrate:

  • A whole person impairment rating of 10% or more
  • A non-threshold injury (e.g., fracture, nerve damage)
  • A medical opinion that treatment is necessary beyond 52 weeks

3. Dispute Resolution Process

If an insurer denies funding, you can:

  • Request a review by the insurer's internal medical advisor
  • Submit a written objection to the
  • Personal Injury Commission* (PIC)
  • Seek independent medical evidence through the PIC's dispute pathway

The PIC's Medical Dispute Review process allows for a second opinion from a registered medical practitioner. This is critical in regional areas where access to specialists may be limited.

4. Time Limits for Claims

You must notify the insurer of your claim within 6 months of the accident. If you fail to do so, you may lose the right to claim for treatment costs. For disputes, the PIC typically allows 60 days from the date of the insurer's decision to request a review.

Hypothetical Example: Funding Dispute in Regional NSW

Imagine a cyclist in regional NSW who sustains a soft tissue injury (threshold injury) and requires physiotherapy. The insurer denies funding, arguing the injury is minor. The treatment provider disputes this, citing:

  • Clinical notes showing persistent pain
  • A 10% whole person impairment rating
  • Evidence of ongoing functional limitation

In this case, the claimant must demonstrate that the injury meets the 'threshold injury' definition under the Motor Accident Guidelines. If the insurer disputes the impairment rating, the PIC may order an independent assessment.

When to Seek Legal Advice

Disputes over treatment funding can be complex, especially when:

  • The insurer refuses to provide a written explanation
  • The claimant is unsure if their injury qualifies for funding
  • The treatment provider is not responding to insurer requests

Legal advice is essential to:

  • Challenge an insurer's refusal to fund necessary treatment
  • Navigate the PIC's dispute resolution process
  • Ensure compliance with the 52-week statutory limit
