Understanding How Insurers Decide on Home Modifications 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've suffered a serious injury in a motor accident and need home modifications to recover, you may wonder how insurers assess your claim. In New South Wales, the Compulsory Third Party (CTP) scheme covers certain home modification costs, but insurers must evaluate each case based on specific criteria. This article explains the factors insurers consider, how regional differences like Western Sydney might affect decisions, and steps to challenge a denied claim.

Key CTP Rules for Home Modifications

Under the Motor Accident Injuries Act 2017, home modifications are considered a 'treatment and care benefit' if they're medically necessary to address injuries caused by a motor accident. The New South Wales Motor Accident Guidelines (SIRA) outline that insurers must approve modifications that:

  • Enable the injured person to perform daily activities safely
  • Prevent further injury or complications
  • Align with a medical practitioner's assessment

Insurers typically require a detailed report from a medical professional confirming the necessity of modifications. For example, a ramp installation might be approved if a doctor states it's needed due to mobility limitations from a spinal injury.

Practical Steps and Evidence That Matter

To support your claim, gather evidence that directly links your injury to the need for modifications. Key documents include:

  • A medical report detailing your injuries and how they affect daily living
  • A written assessment from a physiotherapist or occupational therapist
  • Photos of your home environment and proposed modifications
  • Any correspondence with the insurer about your claim

Insurers often request a 'home modification plan' outlining the specific changes. This should include:

  • A diagram of your home with proposed modifications
  • Cost estimates from approved contractors
  • A statement from your treating medical team confirming the modifications are medically necessary

Time Limits and Dispute Options

You have 52 weeks from the date of your injury to claim certain benefits under the CTP scheme. After this period, weekly income payments and treatment benefits typically stop unless you have a 'whole person impairment' of 10% or more. However, home modifications approved within the 52-week window remain payable regardless of impairment levels.

If your claim is denied, you can request a review by the insurer. If the decision is upheld, you may need to escalate the matter to the NSW Civil and Administrative Tribunal (NCAT) or seek independent medical opinions to challenge the insurer's assessment.

Example: Challenging a Denied Claim

Consider a scenario where a claimant with a serious neck injury is denied a wheelchair ramp. The insurer argues the injury doesn't meet the 'threshold injury' criteria. However, if the claimant's medical team has documented persistent neck pain and limited mobility, the insurer must reconsider under the Motor Accident Guidelines. This example shows how medical evidence can directly impact insurer decisions.

When to Seek Legal Advice

While this article provides general guidance, each claim is unique. Insurers may interpret guidelines differently, and regional variations in practice can affect outcomes. If your claim is denied or you're unsure about your options, consult a solicitor specialising in NSW CTP claims. They can help you:

  • Review your medical records for compliance with SIRA guidelines
  • Challenge an insurer's decision using the correct legal framework
  • Explore options for dispute resolution
