How this affects your claim in practice
In a spinal stenosis claim, the diagnosis is only the starting point. The records should connect MRI or CT identifying the spinal region, level, central or foraminal narrowing and side and clinical findings distinguishing local pain, neurogenic claudication, radiculopathy and spinal-cord signs with the worker's practical limits, including walking and standing tolerance, posture changes, lifting, bending, overhead work or driving according to the affected region and whether proposed duties accommodate neurogenic claudication, neurological deficit or safe mobility. If the insurer disputes whether stenosis is an incidental age-related finding or a condition aggravated by work under the applicable causation test, 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.
My TPD ClaimsAssessment 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 paras 4.1 and 4.5: spinal impairment is assessed using the diagnosis-related estimates (DRE) method. The AMA5 spine range-of-motion model in sections 15.8-15.13 must not be used in NSW workers compensation.
- NSW Guidelines paras 4.14-4.15: alteration of motion segment integrity (AOMSI) is established from the permitted radiographic or structural findings and must relate to trauma, not developmental or degenerative change alone.
- NSW Guidelines paras 4.18, 4.20-4.21 and 4.27-4.29: the DRE category depends on supported clinical findings. Imaging alone, and radiating pain alone, do not establish radiculopathy; EMG is not the NSW category differentiator.
- NSW Guidelines paras 4.30-4.38 and Tables 4.2-4.3: special NSW rules apply to fractures, spinal surgery, pelvis, sacroiliac injury and coccyx injury.
- AMA5 Chapter 15 Tables 15-3, 15-4 and 15-5 provide the lumbar, thoracic and cervical DRE ranges, subject to the NSW modifications.
What injuries or conditions may be assessed?
Spinal stenosis must be assessed from the accepted spinal structure and diagnosis. Possible findings include soft-tissue injury, disc or facet pathology, fracture, nerve-root injury, cord involvement or a post-operative condition.
- The spinal stenosis records should distinguish local pain from a disc lesion, objective radiculopathy, fracture, instability or a surgical consequence because those findings can lead to different DRE categories.
- Symptoms extending into an arm or leg require anatomical correlation. Referred pain is not treated as a nerve-root deficit unless the NSW radiculopathy criteria are met.
Symptoms and findings that matter
For spinal stenosis, flexion means bending forward, extension bending backward, lateral flexion bending sideways, and rotation turning the neck or trunk. These observations help classify the injury but are not converted through the excluded AMA5 spine ROM model.
Possible radiculopathy in a spinal stenosis claim generally needs at least two supported criteria, including a major clinical sign such as reflex asymmetry, localised weakness, reproducible dermatomal sensory loss, a nerve-tension sign or muscle wasting.
Imaging for spinal stenosis should match the level, side and clinical pattern. A degenerative or disc finding can exist without establishing the accepted injury or a higher DRE category.
Where spinal stenosis has been treated surgically, the operation type, level count, repeat procedures and residual objective neurological findings must be documented separately.
What investigations are usually relevant
Investigations for spinal stenosis may include MRI or CT showing the spinal level, disc, canal, foraminal or fracture findings and neurological examination recording power, reflexes, sensation and nerve-root distribution. Each result should answer a defined clinical question and be read with the examination, diagnosis and history.
- Operation reports and post-operative specialist reviews if surgery occurred.
- Certificates of capacity and duties evidence showing sitting, standing, bending, lifting, driving and attendance limits.
How WPI is assessed for this body part
NSW Guidelines Chapter 4 assesses spinal stenosis under the diagnosis-related estimates (DRE) method, using AMA5 Chapter 15 only as modified by NSW.
NSW paragraphs 4.5 and 4.13 exclude the AMA5 spine range-of-motion model. Multilevel disease, recurrence or surgery therefore does not switch a spinal stenosis assessment to ROM.
For spinal stenosis, DRE I is 0% WPI. DRE II requires qualifying findings beyond symptoms alone, while DRE III commonly concerns objective radiculopathy or another specifically listed fracture or post-decompression condition. Within one spinal region, competing findings select the highest valid DRE category; they are not added as separate WPI values.
A spinal stenosis assessment reaches DRE IV only where the evidence supports alteration of motion segment integrity (AOMSI), fusion or specified severe fracture findings. AOMSI is established from permitted structural or radiographic evidence, not ordinary bedside movement loss.
DRE V is reserved for its severe neurological and structural criteria. Persisting radiculopathy after fusion is handled through NSW Table 4.2 rather than automatically moving spinal stenosis to DRE V.
Any arm or leg symptoms attributed to spinal stenosis must match objective nerve-root findings. Radiating pain, an MRI label or one abnormal test does not by itself establish radiculopathy.
Cervical, thoracic and lumbar DRE ranges
Select the supported DRE category before reading the regional range. A diagnosis, scan or pain score does not automatically select the top value.
| Category | Lumbar | Thoracic | Cervical | What the category means in practice |
|---|---|---|---|---|
| DRE I | 0% WPI | 0% WPI | 0% WPI | Symptoms may be reported, but the examination does not show the objective findings required for a higher DRE category. |
| DRE II | 5-8% WPI | 5-8% WPI | 5-8% WPI | A qualifying injury with findings such as guarding, spasm, asymmetric movement loss or non-verifiable radicular complaints, but without the objective radiculopathy or AOMSI required for a higher category. Certain lesser fractures also fall here. |
| DRE III | 10-13% WPI | 15-18% WPI | 15-18% WPI | Commonly applies where objective radiculopathy is established, or where a specified fracture or NSW post-decompression rule places the injury in this category. |
| DRE IV | 20-23% WPI | 20-23% WPI | 25-28% WPI | Commonly concerns AOMSI or a severe compression fracture without the neurological features of DRE V. NSW also places successful and unsuccessful spinal fusion in DRE IV. |
| DRE V | 25-28% WPI | 25-28% WPI | 35-38% WPI | The severe AMA5 category generally requires radiculopathy with AOMSI, or a qualifying severe fracture with neurological compromise. NSW does not move a fusion to DRE V merely because radiculopathy persists after surgery. |

Table and value examples
Spinal surgery with residual symptoms and radiculopathy
Cervical 3% WPI; thoracic 2% WPI; lumbar 3% WPIFor spinal stenosis, this is a surgery modifier only where the surgical and radiculopathy criteria are met; it is not an automatic rating for every spinal operation.
Source: NSW Guidelines Table 4.2
Second and further operated levels
1% WPI modifier for each additional levelFor spinal stenosis, the additional-level modifier does not require residual radiculopathy. Table 4.2 modifiers are combined with each other, then combined with the DRE value using the Combined Values Chart.
Source: NSW Guidelines Table 4.2
Further spinal operations
Second operation 2% WPI; third and subsequent operations 1% WPI eachFor spinal stenosis, these repeat-operation modifiers do not require residual radiculopathy. They are combined under Table 4.2 and then combined with the underlying DRE value, rather than simply added to it.

- Accepted condition and findings
- Spinal stenosis must be assessed from the accepted spinal structure and diagnosis. Possible findings include soft-tissue injury, disc or facet pathology, fracture, nerve-root injury, cord involvement or a post-operative condition. For spinal stenosis, flexion means bending forward, extension bending backward, lateral flexion bending sideways, and rotation turning the neck or trunk. These observations help classify the injury but are not converted through the excluded AMA5 spine ROM model.
- Method to apply
- NSW Guidelines Chapter 4 assesses spinal stenosis under the diagnosis-related estimates (DRE) method, using AMA5 Chapter 15 only as modified by NSW.
- Why no percentage can be assumed
- Back or neck pain alone, without an assessable spinal diagnosis or objective findings, usually does not increase WPI.
What usually does not increase WPI
Back or neck pain alone, without an assessable spinal diagnosis or objective findings, usually does not increase WPI.
Degenerative scan wording by itself is not a rating; the assessment must link the accepted injury to clinical findings.
Radiating pain without objective radiculopathy usually should not be treated as radiculopathy for WPI.
A work capacity restriction is not the same as a permanent impairment percentage.
Evidence checklist
The records for spinal stenosis should include MRI/CT/X-ray reports and the actual spinal level relied on and neurological examination findings: power, reflexes, sensation and nerve tension tests. They are most useful when the diagnosis, examination and practical restrictions are consistent.
- Specialist reports explaining diagnosis, causation, treatment and maximum medical improvement.
- Operation reports, if decompression, fusion or other spinal surgery occurred.
- Duties evidence showing lifting, bending, twisting, sitting, standing, vibration or driving demands.
How this injury commonly happens at work
Work-related spinal stenosis can arise through a work incident aggravating previously asymptomatic canal or foraminal narrowing and repeated lifting, bending, vibration or prolonged driving followed by a medically supported worsening of a spinal condition. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related spinal stenosis can arise through an accepted disc, fracture or post-surgical condition contributing to nerve-root or cord compression. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For spinal stenosis, an insurer may dispute whether stenosis is an incidental age-related finding or a condition aggravated by work under the applicable causation test and whether leg or arm symptoms match the level and side shown on imaging. The written decision should be answered with evidence directed to those reasons.
Further disputes about spinal stenosis may concern whether objective radiculopathy, cord involvement or only local symptoms are present and whether injection, decompression or fusion is reasonably necessary. 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 spinal stenosis may involve rehabilitation and medication review directed to the diagnosed region and functional pattern and injection or pain-specialist care where the treating evidence identifies the proposed purpose. The request should explain the expected functional benefit and its connection to the accepted injury.
Further management of spinal stenosis may involve decompression or fusion review only where clinical findings, imaging and expected benefit support it. The request should explain why the proposed step is connected to the accepted injury and what functional improvement is expected.
Weekly payments and work capacity
Capacity evidence for spinal stenosis should address walking and standing tolerance, posture changes, lifting, bending, overhead work or driving according to the affected region and whether proposed duties accommodate neurogenic claudication, neurological deficit or safe mobility. Proposed duties must be sustainable for the proposed hours, not merely possible once.
For spinal stenosis, capacity evidence should address whether a brief clinic performance has been mistaken for sustainable capacity across a full shift. The question is whether those activities can be performed safely, reliably and for the proposed hours—not whether a task can be attempted once.
How NSW Work Injury Claim can help
For spinal stenosis, a claim review can help to match the spinal level and side on imaging to the examination and separate local pain, radiculopathy, claudication and cord findings. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
For spinal stenosis, a claim review can help to review treatment, capacity and WPI as distinct evidence questions. 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 spinal stenosis claims
How can work cause or aggravate spinal stenosis?
For spinal stenosis, the relevant work history may include a work incident aggravating previously asymptomatic canal or foraminal narrowing, repeated lifting, bending, vibration or prolonged driving followed by a medically supported worsening of a spinal condition, and an accepted disc, fracture or post-surgical condition contributing to nerve-root or cord compression. 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 spinal stenosis?
For spinal stenosis, NSW Guidelines Chapter 4 assesses spinal stenosis under the diagnosis-related estimates (DRE) method, using AMA5 Chapter 15 only as modified by NSW. For spinal stenosis, flexion means bending forward, extension bending backward, lateral flexion bending sideways, and rotation turning the neck or trunk. These observations help classify the injury but are not converted through the excluded AMA5 spine ROM model. 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 spinal stenosis assessment?
A spinal stenosis assessment commonly needs MRI/CT/X-ray reports and the actual spinal level relied on, neurological examination findings: power, reflexes, sensation and nerve tension tests, specialist reports explaining diagnosis, causation, treatment and maximum medical improvement, and operation reports, if decompression, fusion or other spinal surgery occurred. 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 spinal stenosis?
For spinal stenosis, common issues include whether stenosis is an incidental age-related finding or a condition aggravated by work under the applicable causation test, whether leg or arm symptoms match the level and side shown on imaging, and whether objective radiculopathy, cord involvement or only local symptoms are present. 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 spinal stenosis affect weekly payments and suitable duties?
Capacity evidence for spinal stenosis may need to address walking and standing tolerance, posture changes, lifting, bending, overhead work or driving according to the affected region, whether proposed duties accommodate neurogenic claudication, neurological deficit or safe mobility, and whether a brief clinic performance has been mistaken for sustainable capacity across a full shift. 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 spinal stenosis automatically receive a fixed WPI percentage?
No. For spinal stenosis, one verified example is spinal surgery with residual symptoms and radiculopathy: Cervical 3% WPI; thoracic 2% WPI; lumbar 3% WPI, under NSW Guidelines Table 4.2. That value applies only when its stated criteria are met. Back or neck pain alone, without an assessable spinal diagnosis or objective findings, usually does not increase WPI.
