Physiotherapy Approval Time Limits in NSW CTP Claims

A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).

If you're seeking physiotherapy treatment approval under NSW's Compulsory Third Party (CTP) scheme, understanding the time limits is critical. The Motor Accident Injuries Act 2017 (MAIA) and SIRA guidelines outline the process, but the exact deadline for securing approval isn't explicitly stated in the law. Instead, SIRA evaluates whether treatment is necessary and aligns with the claimant's injury and recovery needs. This article explains how SIRA determines approval timelines, what happens if treatment isn't approved on time, and practical steps to take.

NSW CTP Rules Governing Physiotherapy Approval

Under the MAIA, SIRA oversees claims for injuries caused by motor vehicle accidents. Section 4.4 of the Act specifies that weekly benefits and treatment benefits are limited to 52 weeks if the injuries are classified as 'threshold injuries', a term defined in the Motor Accident Guidelines. However, this provision applies to only injuries resulting from the accident, not to all treatment requests.

SIRA assesses whether physiotherapy is 'reasonably necessary' for recovery, considering factors like the nature of the injury, medical evidence, and the claimant's progress. While there's no fixed time limit for approval, delays in securing treatment may affect eligibility for certain benefits. For example, if treatment is delayed beyond 52 weeks and the injuries are threshold injuries, benefits may be reduced or discontinued.

Practical Steps and Evidence for Physiotherapy Approval

To support your claim, gather the following:

  • Medical records confirming the need for physiotherapy
  • Physiotherapy reports detailing the treatment plan and progress
  • Accident details (date, location, and circumstances)
  • Witness statements or photos of the incident
  • Correspondence with your insurer or SIRA

Your treating medical practitioner must also confirm that the treatment is 'reasonably necessary' under the guidelines. Delays in submitting this evidence may lead to disputes over approval.

Time Limits, Disputes and When to Seek Advice

SIRA does not publish a specific time limit for approving physiotherapy treatment, but the 52-week rule applies to threshold injuries. If your treatment is delayed beyond this period, you may need to:

  1. Reassess your injury's classification with a medical expert
  2. Submit updated evidence to demonstrate ongoing treatment needs
  3. Challenge a decision if you believe the approval was denied without justification

If your claim involves a blameless accident or interstate exposure, additional considerations may apply. Always seek legal advice if you face disputes over treatment approval or benefit limits.

Example: What Happens if Approval is Delayed?

Consider a scenario where a claimant sustains a soft-tissue injury (classified as a threshold injury) and begins physiotherapy six weeks post-accident. After 52 weeks, SIRA may reduce benefits if the treatment is deemed no longer 'reasonably necessary.' However, if the claimant's recovery is ongoing and the treatment is still essential, they may need to provide updated medical evidence to challenge this decision.

Next Steps

CTP entitlements depend on the date of the accident, the nature of the injury, and the timeliness of your claim. If you're unsure whether your physiotherapy treatment qualifies for approval, or if your benefits have been reduced, seek guidance from a legal professional. Every claim depends on its own facts.
