How Insurers Evaluate Home Modification Claims in NSW CTP Cases

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

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've suffered a serious injury in a motor accident and need home modifications to regain independence, insurers assess your claim based on the severity of your injury and how it impacts your daily life. Under the Motor Accident Injuries Act 2017 (MAIA), insurers must consider whether your injury meets the legal threshold for compensation, including modifications to your home. This article explains how insurers evaluate these claims, the evidence they require, and when to seek legal advice.

What Factors Do Insurers Consider?

Insurers assess liability by examining:

  • Medical evidence: Detailed reports from doctors confirming your injury's severity and how it affects your ability to live independently.
  • Threshold injury criteria: Under the MAIA, injuries must meet specific neurological or functional criteria (e.g., spinal nerve-root injuries with neurological signs) to qualify for compensation.
  • Home modification necessity: Insurers evaluate whether the modifications are directly related to your injury and essential for your recovery, not lifestyle choices.
  • SIRA guidelines: The State Insurance Regulatory Authority (SIRA) provides frameworks for assessing claims, including how to document the impact of injuries on daily living.

For example, a person with a spinal injury requiring a ramp or handrails would need medical evidence showing how the injury limits their mobility, not just a general statement about needing modifications.

Practical Steps to Support Your Claim

To strengthen your case, gather:

  • Medical records: Including specialist reports, imaging, and notes from consultations.
  • Accident details: Police reports, witness statements, and photos of the incident.
  • Evidence of injury impact: Diaries or assessments showing how the injury affects your ability to live independently.
  • Home modification plans: Documentation from architects or contractors outlining the modifications and their medical necessity.

Insurers may request these documents to verify that the modifications are directly linked to your injury and not a personal preference.

Time Limits and Dispute Options

You have 52 weeks from the accident date to claim benefits for injuries that meet the threshold. However, serious injuries may extend this period if the claimant requires long-term support. If the insurer disputes your claim, you can:

  • Request a review by SIRA or the NSW Civil and Administrative Tribunal (NCAT).
  • Seek legal advice to challenge the insurer's assessment of your injury's severity.

When to Seek Legal Advice

If the insurer denies your claim or disputes the extent of your injuries, a solicitor can help you:

  • Challenge the insurer's interpretation of the MAIA.
  • Negotiate a fair settlement based on your medical evidence.
  • Lodge a formal dispute with SIRA or NCAT.
