If you're dealing with a legacy claim under the Motor Accidents Compensation Act 1999 (MAC Act) in New South Wales, understanding how treatment and rehabilitation planning works is critical. These claims, which predate the current Motor Accident Injuries Act 2017 (MAIA), operate under different rules for managing medical care and long-term recovery. This article explains how SIRA’s guidelines apply to legacy claims, what treatment costs are covered, and how rehabilitation planning works under NSW law.

What are MAC Act legacy claims and how do they differ from standard CTP claims?

MAC Act legacy claims apply to injuries sustained before 1 December 2017, when the old scheme was replaced by the MAIA. While both schemes aim to cover medical treatment and rehabilitation, the MAC Act’s rules for funding and managing care are distinct. Under the MAC Act, claimants could claim treatment costs directly from the insurer, with no cap on the number of sessions. In contrast, the MAIA limits weekly benefits after 52 weeks of threshold injuries. For legacy claims, treatment planning must align with the MAC Act’s specific funding rules, which are now administered by SIRA.

How does SIRA’s approach to treatment and rehabilitation planning apply to legacy claims?

SIRA’s guidelines for legacy claims emphasize a structured approach to managing medical care. Claimants must work with approved medical practitioners to document treatment needs, and rehabilitation plans must be reviewed regularly. Under the MAC Act, the insurer is responsible for paying for all medically necessary treatments, including physiotherapy, occupational therapy, and specialist consultations. However, claimants must ensure that treatment plans are evidence-based and approved by the insurer to avoid disputes.

What are the funding rules for treatment costs in MAC Act legacy claims?

Under the MAC Act, treatment costs are funded through the claimant’s injury claim, not through Medicare or private health insurance. This means that all medical expenses related to the injury, such as scans, medications, and therapy sessions, are covered by the insurer. However, claimants must keep detailed records of all treatment costs, including receipts and medical reports, to ensure compliance with the scheme’s requirements. SIRA’s guidelines also require that treatment plans be reviewed annually to reflect the claimant’s progress.

How do legacy claims impact long-term rehabilitation planning under NSW CTP laws?

Legacy claims under the MAC Act have specific rules for long-term rehabilitation. While the MAIA limits weekly benefits after 52 weeks, legacy claims do not have this restriction. Instead, rehabilitation planning under the MAC Act focuses on restoring the claimant’s ability to work and live independently. This includes vocational assessments, lifestyle modifications, and access to support services. Claimants must ensure that their rehabilitation plan is tailored to their individual needs and approved by the insurer.

Practical steps for managing MAC Act legacy claims

  1. Document all treatment costs: Keep detailed records of all medical expenses, including receipts, invoices, and medical reports. This ensures that the insurer covers all necessary treatments.
  2. Work with approved medical practitioners: Ensure that all treatment plans are developed by medical professionals registered with SIRA. This helps avoid disputes over the necessity of care.
  3. a Review rehabilitation plans annually: Regularly update your rehabilitation plan to reflect your progress and any changes in your condition. This helps maintain eligibility for ongoing support.
  4. Seek clarification on funding disputes: If you believe the insurer is not covering necessary treatments, contact SIRA’s claims team for guidance. Disputes can also be resolved through the NSW Civil and Administrative Tribunal.

When to seek legal advice

While SIRA provides clear guidelines for managing MAC Act legacy claims, the process can be complex. If you’re unsure whether your treatment plan is compliant, or if you believe the insurer is not covering necessary costs, it’s important to seek legal advice. A solicitor can help you understand your rights and ensure that your claim is processed correctly.
