Home Modifications, What the PIC Expect in NSW CTP Disputes

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).

If you’ve suffered a serious injury in a motor accident and need home modifications to recover, insurers may dispute the claim. Under NSW’s Compulsory Third Party (CTP) scheme, the Personal Injury Commission (PIC) assesses whether modifications are reasonable and necessary. This article explains what insurers typically expect, how SIRA guidelines shape claims, and practical steps to support your case.

Legal Framework for Home Modifications in CTP Claims

NSW CTP claims are governed by the Motor Accident Injuries Act 2017 (MAIA). Under this scheme, claimants can seek compensation for injuries, including modifications to their home to accommodate recovery. SIRA (State Insurance Regulatory Authority) provides authoritative guidance on what constitutes a reasonable modification.

SIRA’s guidelines state that home modifications must be:

  • Necessary to address the injury’s impact on daily living
  • Reasonable in cost and scope
  • Supported by medical evidence showing the injury’s effect

Insurers may challenge claims by questioning whether the modification is directly related to the injury or if it exceeds standard care requirements.

Practical Steps and Evidence to Support Your Claim

To strengthen your case, gather the following:

  • Medical reports from a registered medical practitioner detailing how the injury affects your ability to live independently
  • Photos or diagrams of the proposed modifications
  • Quotes from approved contractors for the work
  • Evidence of prior injuries that necessitate the modification
  • Documentation of daily living challenges (e.g., difficulty climbing stairs, managing household tasks)

For example, if a spinal injury limits mobility, a ramp or handrails may be justified. However, insurers may dispute a request for a full bathroom renovation unless medical evidence clearly links the injury to the need for such changes.

Common Dispute Points and How They’re Resolved

Insurers often dispute claims on these grounds:

  • Unclear connection to the injury, Modifications not directly tied to the accident may be rejected
  • Cost concerns, Claims exceeding SIRA’s reasonable cost thresholds may be limited
  • Lack of medical evidence, Without proper documentation, insurers may refuse to approve the modification

Under the MAIA, claimants can request an internal review of the PIC’s decision. If disputes persist, the PIC’s Medical Advisory Committee may reassess the claim based on updated medical evidence.

Time Limits and When to Seek Advice

CTP claims must be submitted within 52 weeks of the accident for certain benefits, but serious injury claims may extend beyond this period. However, delays can weaken your case, as insurers may argue the modification is no longer necessary.

If your claim is disputed, seek legal advice promptly. A solicitor can help challenge the PIC’s decision, request a medical review, or negotiate a fair settlement. Remember, the PIC’s internal review process allows for reconsideration of claims based on new evidence.

Final Steps for Claimants

If you’re facing a dispute over home modifications for a serious injury, act quickly. Gather all relevant evidence, submit your claim within the required timeframe, and seek legal guidance if the PIC denies your request. The right support can make the difference between a successful claim and a rejected one.
