How Late CTP Payments Affect Funding for Treatment

If a Compulsory Third Party (CTP) insurer delays payment of statutory benefits, it can significantly impact your ability to fund essential treatment. Under NSW law, insurers must pay benefits promptly, and delays may trigger penalty interest. This article explains how late payments affect treatment funding, referencing SIRA guidelines and legal requirements for CTP claims in Balmain.

NSW CTP Rules Behind Delayed Payments

The Motor Accident Injuries Act 2017 governs CTP claims, requiring insurers to pay statutory benefits within 28 days of a claim being accepted. If payments are delayed beyond this period, penalty interest may accrue under the NSW Civil Procedure Act 2009 (s 136). This interest is calculated on the unpaid amount and can increase the total funding available for treatment.

SIRA guidelines clarify that statutory benefits include weekly income payments, treatment and care benefits, and compensation for permanent impairment. Delays in accessing these funds can force claimants to use personal savings or seek alternative financing for medical care.

Practical Steps for Claimants in Balmain

To address late payments, claimants should:

  • Document all communication with the insurer, including dates and reference numbers
  • Request written confirmation of payment delays
  • Keep medical records showing the link between treatment costs and delayed funding
  • Report persistent delays to SIRA's claims helpline

Evidence of financial hardship, such as bank statements or medical bills, can support claims for additional funding. Claimants should also note that penalty interest calculations depend on the exact date of payment delays.

Time Limits and When to Seek Advice

Statutory benefits must be claimed within 52 weeks of the accident under s 4.4 of the Motor Accident Injuries Act 2017. However, interest calculations can extend beyond this period. If an insurer refuses to pay benefits or disputes penalty interest, claimants should seek legal advice before the 52-week deadline expires.

A hypothetical example illustrates this: If a claimant sustains a soft-tissue injury in Balmain and receives weekly payments for 26 weeks, but the insurer delays payments for 12 weeks, penalty interest could increase the total funding by up to 10% depending on the interest rate applied.

Next Steps for Claimants
