How NSW CTP Insurers Evaluate Ankle Fractures in Car Accidents

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).

Ankle fractures following a car accident in NSW are assessed under the Compulsory Third Party (CTP) scheme, which determines liability based on fault and injury severity. Insurers evaluate claims by considering medical evidence, accident circumstances, and SIRA guidelines to decide if a claimant qualifies for benefits or damages. This article explains how insurers assess liability for ankle fractures, focusing on Bankstown NSW.

Key Legal Framework for Ankle Fracture Claims

Under the Motor Accident Injuries Act 2017, CTP insurers must provide benefits for injuries caused by motor vehicle accidents. Ankle fractures are classified as 'threshold injuries' if they meet specific medical criteria, including spinal nerve-root injuries with neurological signs. SIRA’s Motor Accident Guidelines define threshold injuries as those requiring treatment, such as fractures, ligament tears, or sprains that cause functional limitation.

Insurers assess whether an ankle fracture meets the threshold injury definition by reviewing medical records. For example, a broken tibia or fibula with restricted movement may qualify, while minor sprains without structural damage typically do not. If the injury is classified as a threshold injury, the claimant is entitled to weekly income payments and treatment benefits under the CTP scheme.

Factors Influencing Liability Assessment

Insurers evaluate liability by determining fault and injury causation. In Bankstown NSW, claims involving ankle fractures often hinge on whether the accident involved a motor vehicle and if the injury resulted from the crash. For instance, a pedestrian struck by a car or a cyclist colliding with a vehicle would fall under CTP coverage, provided the injury meets the threshold criteria.

Contributory fault may also impact claims. If the claimant contributed to the accident (e.g., distracted driving or failure to wear a seatbelt), insurers may reduce benefits. However, CTP claims are not based on fault in the same way as common law damages; they focus on whether the injury qualifies under the scheme’s rules.

Practical Steps and Evidence for Ankle Fracture Claims

To support a claim, injured individuals must provide medical evidence confirming the ankle fracture and its connection to the accident. This includes X-rays, MRI scans, and reports from a medical practitioner. Accident details, such as police reports or witness statements, help establish fault and the vehicle’s involvement.

Insurers also consider the claimant’s ability to work. If an ankle fracture prevents employment for 52 weeks or more, weekly income benefits may be available. However, if the injury is a threshold injury, benefits are generally limited to 52 weeks under the Act. This distinction is critical for claims involving prolonged recovery.

Disputes, Time Limits, and When to Seek Advice

Insurers may dispute claims by challenging the injury’s classification or fault. For example, they might argue an ankle fracture is a minor sprain and not a threshold injury. In such cases, claimants should seek independent medical opinions to reinforce their case.

Time limits are also important. While CTP claims have no strict deadline, delays can complicate disputes over liability or injury classification. For instance, if a claimant waits too long to report an ankle fracture, insurers may question the injury’s connection to the accident.

Conclusion

Ankle fractures in NSW CTP claims require careful assessment of medical evidence, fault, and injury classification. Insurers use SIRA guidelines to determine if a fracture meets threshold injury criteria, which affects eligibility for benefits. Time limits and disputes over liability can further complicate claims. Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
