How this affects your claim in practice
In a catastrophic injury claim, the diagnosis is only the starting point. The records should connect complete trauma, intensive-care, surgical and rehabilitation records and specialist evidence for each accepted body system with the worker's practical limits, including mobility, cognition, communication, self-care, endurance, safety and reliable attendance and whether any proposed employment exists in reality and accommodates all accepted restrictions. If the insurer disputes whether every consequential condition is accepted, the response should address that reason directly.

Other claims that may need to be considered
A work injury claim is often the first issue, but some facts can raise a separate insurance or injury pathway. These links are included only where the overlap may genuinely matter.
Long-term inability to return to work
If you are unlikely to return to suitable work long-term, you may also need to check whether TPD insurance through superannuation is available. TPD is separate from workers compensation.

- NSW Guidelines for the Evaluation of Permanent Impairment, paras 1.8-1.12: NSW Guidelines control the assessment method and AMA5 is used only where adopted and not modified.
- NSW Guidelines para 1.12: AMA5 Chapter 18 pain is excluded; chronic pain is assessed through the underlying diagnosed condition, while CRPS is assessed under the relevant NSW method.
- NSW Guidelines para 1.15: assessment should usually wait until maximum medical improvement, meaning the condition is stable and unlikely to change substantially in the next year.
- Serious injury assessment should identify each accepted body system before applying the relevant NSW chapter; WPI is not calculated from injury severity labels alone.
- NSW Guidelines paras 1.17-1.20 and 1.31: separate physical impairments and distinct non-psychological treatment consequences are combined only where permitted, with overlap removed; primary psychological impairment remains separate.
Injuries and consequences that may need assessment
Catastrophic injury is not a single impairment category. The accepted diagnosis must identify the structure or body system affected and the permanent consequence being assessed.
- A supported work mechanism: a high-energy event causing severe injury across several body systems.
- A supported work mechanism: a major fall, vehicle, machinery, explosion or crush incident.
- For catastrophic injury, separate diagnoses and consequential conditions should be recorded individually so that one broad injury label is not used for different assessment methods.
Symptoms and findings that matter
A finding relevant to catastrophic injury: complete trauma, intensive-care, surgical and rehabilitation records.
A finding relevant to catastrophic injury: specialist evidence for each accepted body system.
A finding relevant to catastrophic injury: care, equipment, accommodation and functional assessments.
Mobility, cognition, communication, self-care, endurance, safety and reliable attendance.
What investigations are usually relevant
Investigations for catastrophic injury may include complete trauma, intensive-care, surgical and rehabilitation records and specialist evidence for each accepted body system. Each result should answer a defined clinical question and be read with the examination, diagnosis and history.
- Care, equipment, accommodation and functional assessments.
- A consolidated injury schedule preventing accepted conditions from being overlooked.
How WPI is assessed for this body part
Catastrophic is a severity description, not a WPI method.
Each accepted permanent body-system loss is assessed under its own NSW chapter and combined where permitted.
Care needs, economic loss and WPI are related evidence issues but not interchangeable calculations.
Identify each accepted body system first, then apply the relevant NSW chapter for that condition.
Amputation, burns, scars, fractures, internal injuries and neurological injuries use different methods; do not rate by seriousness label alone.

What usually does not increase WPI
The existence of a dispute about whether every consequential condition is accepted does not replace the measurements and criteria required by the controlling impairment method.
The existence of a dispute about whether treatment, equipment and care needs are reasonably necessary does not replace the measurements and criteria required by the controlling impairment method.
Treatment, time away from work and an imaging or diagnosis label do not by themselves establish the WPI result for catastrophic injury.
Evidence checklist
The records for catastrophic injury should include coordinated specialist rehabilitation across each accepted body system. They are most useful when the diagnosis, examination and practical restrictions are consistent.
How this injury commonly happens at work
Work-related catastrophic injury can arise through a high-energy event causing severe injury across several body systems and a major fall, vehicle, machinery, explosion or crush incident. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related catastrophic injury can arise through an incident producing permanent mobility, cognitive, organ, sensory or care consequences. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For catastrophic injury, an insurer may dispute whether every consequential condition is accepted and whether treatment, equipment and care needs are reasonably necessary. The written decision should be answered with evidence directed to those reasons.
Further disputes about catastrophic injury may concern whether capacity and permanent impairment have been assessed body system by body system. The decision notice should identify which issue is relied on and the evidence said to support it.
Treatment and surgery issues
Depending on the diagnosis and treating opinion, management of catastrophic injury may involve equipment, accommodation and care planning based on assessed need and review of future procedures without treating planned treatment or care as automatic WPI. The request should explain the expected functional benefit and its connection to the accepted injury.
Weekly payments and work capacity
Capacity evidence for catastrophic injury should address whether any proposed employment exists in reality and accommodates all accepted restrictions and interaction between medical treatment, care and vocational planning. Proposed duties must be sustainable for the proposed hours, not merely possible once.
How NSW Work Injury Claim can help
For catastrophic injury, a claim review can help to create a complete accepted-injury and evidence matrix and coordinate body-system assessments and combination rules. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.

Common questions about catastrophic injury claims
How can work cause or aggravate catastrophic injury?
For catastrophic injury, the relevant work history may include a high-energy event causing severe injury across several body systems, a major fall, vehicle, machinery, explosion or crush incident, and an incident producing permanent mobility, cognitive, organ, sensory or care consequences. A claim still depends on the actual chronology and medical evidence. The records should identify what changed, when symptoms began or worsened, and how the diagnosed condition affects the worker's duties.
How is WPI assessed for catastrophic injury?
For catastrophic injury, catastrophic is a severity description, not a WPI method. A finding relevant to catastrophic injury: complete trauma, intensive-care, surgical and rehabilitation records. The assessor must apply the NSW Guidelines to the accepted, stable condition; the diagnosis or an operation does not by itself determine a percentage.
Which records are most useful for a catastrophic injury assessment?
A catastrophic injury assessment commonly needs complete trauma, intensive-care, surgical and rehabilitation records, specialist evidence for each accepted body system, care, equipment, accommodation and functional assessments, and a consolidated injury schedule preventing accepted conditions from being overlooked. Those records are most useful when they describe the same diagnosis, examination findings, treatment history and practical work restrictions.
What does an insurer commonly dispute about catastrophic injury?
For catastrophic injury, common issues include whether every consequential condition is accepted, whether treatment, equipment and care needs are reasonably necessary, and whether capacity and permanent impairment have been assessed body system by body system. The response should address the insurer's stated reason with the relevant chronology, clinical findings, investigations and duties evidence rather than relying on the diagnosis alone.
How can catastrophic injury affect weekly payments and suitable duties?
Capacity evidence for catastrophic injury may need to address mobility, cognition, communication, self-care, endurance, safety and reliable attendance, whether any proposed employment exists in reality and accommodates all accepted restrictions, and interaction between medical treatment, care and vocational planning. A certificate should describe what the worker can do safely and sustainably. Proposed duties should then be checked against those restrictions and the real demands of the job.
Does catastrophic injury automatically receive a fixed WPI percentage?
No. For catastrophic injury, one verified example is distinct physical body-system values: Combine highest to lowest with the Combined Values Chart, under NSW Guidelines paras 1.17-1.20. That value applies only when its stated criteria are met. Care needs, economic loss and WPI are related evidence issues but not interchangeable calculations.
