How this affects your claim in practice
In an occupational lung disease claim, the diagnosis is only the starting point. The records should connect respiratory specialist diagnosis identifying the disease and applicable compensation pathway and valid spirometry, diffusion-capacity, imaging and other clinically indicated testing with the worker's practical limits, including dust or fume exposure, respirator use, exertion, stairs, heat and shift recovery and whether duties can be sustained without unsafe exposure or respiratory symptoms. If the insurer disputes whether the condition is an ordinary disease injury or a scheduled dust disease requiring the separate Dust Diseases Care pathway, the response should address that reason directly.
Assessment source
- 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.
- NSW Guidelines Chapter 8, paras 8.3-8.4 and 8.15-8.16: respiratory disorders other than asthma use AMA5 Table 5-12, with valid physiological testing and a reasoned whole-number selection within Classes 2-4.
- NSW Guidelines paras 8.5-8.7: asthma uses the modified AMA5 Tables 5-9 and 5-10 score from repeat testing under maximal treatment; bronchial challenge testing and PC20 are not scored.
- NSW Guidelines para 8.12: pneumoconiosis is dealt with under the separate NSW dust-diseases legislation rather than the ordinary Chapter 8 WPI pathway.
- Workers Compensation Act 1987 (NSW), s 4(c): a dust disease within the Dust Diseases Act is excluded from the ordinary Act definition of injury, subject to the statutory exception for a worker employed in or about a mine.
- Workers' Compensation (Dust Diseases) Act 1942 (NSW), s 3 and Schedule 1: asbestosis and silicosis are scheduled dust diseases dealt with under the separate dust-diseases scheme.
- SIRA permanent-impairment Guidelines para 8.12: pneumoconiosis is not assessed under the ordinary respiratory WPI chapter because the separate dust-diseases legislation applies.
- icare Dust Diseases Care assesses the covered diagnosis, harmful occupational dust exposure while employed in NSW and disability from the disease. Its medical and benefit process is not an ordinary section 66 WPI calculation.
- Workers Compensation Act 1987 (NSW), ss 4(a), 4(b) and 9A: an acute personal injury and a disease injury use different employment-causation tests. A disease contracted or aggravated after the 2012 amendments requires employment to be the main contributing factor; a non-disease injury generally requires employment to be a substantial contributing factor.
- The legal liability test and the permanent-impairment method answer different questions. Establishing workplace exposure does not itself select a WPI chapter, class or percentage.
Occupational conditions and exposure patterns
Occupational lung disease 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: repeated inhalation of dust, fibres, fumes, smoke, vapour or biological material causing a diagnosed respiratory disease.
- A supported work mechanism: an acute inhalation event leaving a stable respiratory consequence.
- For occupational lung disease, 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 occupational lung disease: respiratory specialist diagnosis identifying the disease and applicable compensation pathway.
A finding relevant to occupational lung disease: valid spirometry, diffusion-capacity, imaging and other clinically indicated testing.
A finding relevant to occupational lung disease: a detailed task-by-task exposure and smoking or non-work respiratory history.
Dust or fume exposure, respirator use, exertion, stairs, heat and shift recovery.
What investigations are usually relevant
Investigations for occupational lung disease may include respiratory specialist diagnosis identifying the disease and applicable compensation pathway and valid spirometry, diffusion-capacity, imaging and other clinically indicated testing. Each result should answer a defined clinical question and be read with the examination, diagnosis and history.
- A detailed task-by-task exposure and smoking or non-work respiratory history.
- Dust, chemical, ventilation, respiratory-protection and health-surveillance records where available.
How WPI is assessed for this body part
The diagnosis determines the pathway. Ordinary non-asthma respiratory disease generally uses AMA5 Table 5-12 as modified by NSW; occupational asthma uses the separate NSW asthma score.
Pneumoconiosis, including scheduled asbestosis or silicosis, is excluded from ordinary Chapter 8 WPI assessment and proceeds under the separate dust-diseases legislation.
For ordinary Table 5-12 assessment, valid FVC, FEV1, FEV1/FVC, DCO and clinically available exercise results identify the supported class. The assessor then explains the precise whole-number point within Classes 2-4 from the complete clinical circumstances.

Method illustration
This is a non-numeric illustration of the assessment sequence. It does not predict a WPI result.
- Accepted condition and findings
- Occupational lung disease is not a single impairment category. The accepted diagnosis must identify the structure or body system affected and the permanent consequence being assessed. A finding relevant to occupational lung disease: respiratory specialist diagnosis identifying the disease and applicable compensation pathway.
- Method to apply
- The diagnosis determines the pathway. Ordinary non-asthma respiratory disease generally uses AMA5 Table 5-12 as modified by NSW; occupational asthma uses the separate NSW asthma score.
- Why no percentage can be assumed
- Breathlessness, imaging or an occupational-lung-disease label does not identify the statutory pathway or WPI class by itself.
What usually does not increase WPI
Breathlessness, imaging or an occupational-lung-disease label does not identify the statutory pathway or WPI class by itself.
Poor-effort or non-repeatable pulmonary testing should not be converted into an impairment percentage.
A dust-disease diagnosis should not be presented through the ordinary section 66 WPI framework.
Evidence checklist
The records for occupational lung disease should include condition-specific respiratory treatment, monitoring and rehabilitation. They are most useful when the diagnosis, examination and practical restrictions are consistent.
How this injury commonly happens at work
Work-related occupational lung disease can arise through repeated inhalation of dust, fibres, fumes, smoke, vapour or biological material causing a diagnosed respiratory disease and an acute inhalation event leaving a stable respiratory consequence. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related occupational lung disease can arise through occupational asthma, hypersensitivity pneumonitis or another non-dust-scheme lung disease supported by specialist evidence. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For occupational lung disease, an insurer may dispute whether the condition is an ordinary disease injury or a scheduled dust disease requiring the separate Dust Diseases Care pathway and whether employment was the main contributing factor to contracting or aggravating an ordinary disease injury. The written decision should be answered with evidence directed to those reasons.
Further disputes about occupational lung disease may concern whether objective respiratory findings are attributable to the accepted occupational exposure and whether the proposed work restrictions match the measured respiratory function and exposure risk. 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 occupational lung disease may involve exposure avoidance or control measures supported by the treating respiratory evidence. The request should explain the expected functional benefit and its connection to the accepted injury.
Weekly payments and work capacity
Capacity evidence for occupational lung disease should address whether duties can be sustained without unsafe exposure or respiratory symptoms and whether medication, oxygen or treatment timing affects attendance. Proposed duties must be sustainable for the proposed hours, not merely possible once.
How NSW Work Injury Claim can help
For occupational lung disease, a claim review can help to identify the accepted diagnosis and correct statutory pathway and check pulmonary-test validity and the exposure history. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
For occupational lung disease, a claim review can help to match proposed duties to respiratory restrictions and exposure controls. 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 occupational lung disease claims
How can work cause or aggravate occupational lung disease?
For occupational lung disease, the relevant work history may include repeated inhalation of dust, fibres, fumes, smoke, vapour or biological material causing a diagnosed respiratory disease, an acute inhalation event leaving a stable respiratory consequence, and occupational asthma, hypersensitivity pneumonitis or another non-dust-scheme lung disease supported by specialist evidence. 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 occupational lung disease?
For occupational lung disease, the diagnosis determines the pathway. Ordinary non-asthma respiratory disease generally uses AMA5 Table 5-12 as modified by NSW; occupational asthma uses the separate NSW asthma score. A finding relevant to occupational lung disease: respiratory specialist diagnosis identifying the disease and applicable compensation pathway. 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 an occupational lung disease assessment?
An occupational lung disease assessment commonly needs respiratory specialist diagnosis identifying the disease and applicable compensation pathway, valid spirometry, diffusion-capacity, imaging and other clinically indicated testing, a detailed task-by-task exposure and smoking or non-work respiratory history, and dust, chemical, ventilation, respiratory-protection and health-surveillance records where available. 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 occupational lung disease?
For occupational lung disease, common issues include whether the condition is an ordinary disease injury or a scheduled dust disease requiring the separate Dust Diseases Care pathway, whether employment was the main contributing factor to contracting or aggravating an ordinary disease injury, and whether objective respiratory findings are attributable to the accepted occupational exposure. 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 occupational lung disease affect weekly payments and suitable duties?
Capacity evidence for occupational lung disease may need to address dust or fume exposure, respirator use, exertion, stairs, heat and shift recovery, whether duties can be sustained without unsafe exposure or respiratory symptoms, and whether medication, oxygen or treatment timing affects attendance. 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 occupational lung disease automatically receive a fixed WPI percentage?
No. For occupational lung disease, one verified example is ordinary non-asthma respiratory classes: Class 1: 0%; Class 2: 10-25%; Class 3: 26-50%; Class 4: 51-100% WPI, under AMA5 Table 5-12, subject to NSW Chapter 8. That value applies only when its stated criteria are met. Breathlessness, imaging or an occupational-lung-disease label does not identify the statutory pathway or WPI class by itself.
