CRPS After Road Trauma: How NSW CTP Insurers Assess Liability in Illawarra and South Coast

This article explains how NSW CTP insurers assess liability for chronic regional pain syndrome (CRPS) claims following road trauma, focusing on the Illawarra and South Coast regions. It outlines factors like medical evidence, SIRA guidelines, and time limits, while advising claimants on next steps.

How NSW CTP Insurers Evaluate CRPS 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).

Chronic regional pain syndrome (CRPS) following a road trauma is a complex injury that requires careful assessment by NSW CTP insurers. Under the Motor Accident Injuries Act 2017, insurers must determine whether a claimant meets the threshold injury criteria outlined in the Motor Accident Guidelines. For CRPS claims, this involves evaluating medical evidence to confirm the injury's onset and link it to the accident.

Key Factors in Liability Assessments

NSW CTP insurers assess liability for CRPS claims by considering:

  • Medical documentation: Detailed records from healthcare providers confirming the diagnosis, onset date, and treatment history.
  • SIRA guidelines: The State Insurance Regulatory Authority (SIRA) provides criteria for determining threshold injuries, including specific neurological signs and pain patterns.
  • Injury causation: Evidence that the CRPS condition arose directly from the road trauma, not pre-existing conditions or unrelated factors.
  • 52-week benefit limit: If only threshold injuries are involved, weekly benefits and treatment payments generally stop after 52 weeks, as per s 4.4 of the Motor Accident Injuries Act 2017.

Practical Steps for Claimants

To support a CRPS claim, injured persons should:

  • Obtain a formal diagnosis from a medical practitioner familiar with SIRA's threshold injury criteria.
  • Document all treatment records, including specialist consultations and pain management plans.
  • Preserve accident details, such as police reports, witness statements, and vehicle inspection reports.
  • Notify the at-fault driver's insurer promptly to initiate the claims process.

Disputes and When to Seek Advice

If an insurer denies or limits a CRPS claim, claimants may need to:

  • Request a review of the assessment, citing discrepancies in medical evidence or SIRA guidelines.
  • Seek independent medical opinions to challenge the insurer's interpretation of the injury.
  • Consult a legal professional if disputes escalate, as time limits for lodging claims (generally 52 weeks) apply.

Example Scenario

Consider a claimant who developed CRPS after a car accident on the Illawarra Highway. The insurer would assess whether the injury meets the threshold criteria by reviewing medical records showing persistent pain, swelling, and neurological signs. If the claimant's symptoms align with SIRA's guidelines, they may qualify for treatment benefits and income support.
