Shoulder Injuries in NSW CTP Claims: How Insurers Assess and Decide

This article explains how insurers assess shoulder injury claims under NSW’s CTP scheme, including the legal criteria, common grounds for denial, and practical steps to challenge decisions. It outlines the evidence that matters and when to seek advice, with reference to SIRA guidelines and the Motor Accident Injuries Act 2017.

Understanding Shoulder Injury Claims in NSW CTP Insurance

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).

A shoulder injury sustained in a motor vehicle accident in New South Wales may lead to compensation through the Compulsory Third Party (CTP) insurance scheme. Insurers assess these claims based on the Motor Accident Injuries Act 2017 (MAIA), which sets out the legal framework for determining entitlements. In Greater Sydney, as elsewhere in NSW, decisions are made by the insurer of the at-fault vehicle, or by the Nominal Defendant if fault is disputed. The insurer’s decision will depend on whether the injury meets the legal thresholds for benefits, including whether it qualifies as a threshold injury, and whether it results in a permanent impairment. These determinations are guided by the Motor Accident Injuries Regulation 2017 and the Motor Accident Guidelines issued by the State Insurance Regulatory Authority (SIRA).

What Insurers Consider When Assessing Shoulder Injuries

Insurers assess shoulder injury claims by examining medical evidence, the nature and severity of the injury, and whether it meets the legal definition of a threshold injury under MAIA. A shoulder injury may be considered a threshold injury if it results in a permanent impairment of at least 10% of the whole person, or if it causes a permanent loss of function. Common shoulder injuries include rotator cuff tears, shoulder dislocations, and nerve injuries such as brachial plexus damage. The insurer will review diagnostic imaging (X-rays, MRI), clinical assessments, and treatment records to determine if the injury is attributable to the motor accident and whether it meets the threshold for benefits.

The insurer will also assess whether the injury is a soft-tissue injury. Under the Motor Accident Guidelines, a soft-tissue injury includes trauma to muscles, tendons, ligaments, or nerves, but excludes fractures unless they are non-displaced and not requiring surgery. A spinal nerve-root injury that causes neurological signs other than radiculopathy may still be classified as a soft-tissue injury, even if it involves nerve damage. Insurers rely on these definitions to determine eligibility for treatment and care benefits, weekly income payments, and damages.

Common Reasons for Denial or Reduction of Claims

Insurers may deny or reduce a claim for a shoulder injury if they determine that the injury was not caused by the motor accident, or that it does not meet the threshold for benefits. Common grounds for dispute include:

  • The injury pre-existed the accident and was not aggravated by it.
  • The injury is not clinically supported by medical evidence, such as imaging or objective neurological signs.
  • The injury is not considered a threshold injury under the Motor Accident Guidelines, particularly if the impairment is below 10% or if there is no permanent loss of function.
  • The claimant failed to seek timely medical treatment or did not provide sufficient evidence to support the claim.

In Greater Sydney, where motor accident claims are frequent, insurers may also challenge claims based on the timing of treatment, consistency of symptoms, or the presence of psychological factors. If the claimant has a history of prior shoulder injuries, the insurer may argue that the current injury is not new or not attributable to the accident.

Evidence That Matters in a Shoulder Injury Claim

To support a claim for a shoulder injury, the claimant should gather and preserve the following evidence:

  • Medical records from the treating practitioner, including diagnosis, treatment plan, and progress notes.
  • Diagnostic imaging reports (X-ray, MRI, ultrasound) showing the injury.
  • A report from a medical practitioner assessing the degree of whole person impairment, if applicable.
  • Details of any surgery, rehabilitation, or ongoing treatment.
  • A record of lost income, if applicable, supported by payslips or employer letters.
  • Photographs of the accident scene, vehicle damage, or visible injury, if taken promptly.
  • Witness statements, if available, confirming the impact and the claimant’s immediate symptoms.

Insurers will review this evidence to determine if the injury is causally linked to the accident and whether it meets the legal criteria for benefits. A consistent and documented medical history strengthens the claim.

Time Limits and Dispute Options

There are time limits that apply to motor accident claims in NSW. A claim for treatment and care benefits must be made within 12 months of the accident. A claim for weekly income payments must be made within 12 months of the date the claimant first became unable to work due to the injury. For damages, a claim must be made within three years of the accident, or within three years of the date the claimant first knew they had a claim.

If an insurer denies or reduces a claim, the claimant may dispute the decision. The first step is to request a review from the insurer, which must be completed within 28 days of the decision. If the review is unsatisfactory, the claimant may apply to the Civil and Administrative Tribunal (NCAT) for a determination. The claimant may also seek an independent medical assessment to challenge the insurer’s evaluation of the injury.

When to Seek Independent Advice

A shoulder injury claim may involve complex medical and legal issues, particularly if the injury is not clearly linked to the accident, or if the insurer disputes the extent of impairment. In Greater Sydney, where CTP claims are common, claimants may benefit from independent legal advice to understand their rights and to challenge decisions that appear inconsistent with the Motor Accident Guidelines or SIRA’s policy direction.

A hypothetical example: A 42-year-old driver in Sydney sustained a rotator cuff tear in a rear-end collision. The injury was confirmed by MRI and diagnosed as a soft-tissue injury. The claimant sought treatment within a week and was unable to return to work for 14 weeks. The insurer initially denied weekly income payments, arguing the injury was not a threshold injury. After obtaining a second medical opinion confirming a 12% whole person impairment, the claimant successfully challenged the decision through a review and was awarded benefits.
