How this affects your claim in practice
In an amputation claim, the diagnosis is only the starting point. The records should connect emergency and operation records identifying the exact amputation level, side and structures retained and the insurer decisions showing whether the amputation and any later revision are accepted with the worker's practical limits, including prosthetic tolerance, walking distance, balance, stairs, uneven ground or transfer ability for lower-limb loss and grip, pinch, protective sensation, tool control and bilateral task demands for upper-limb or digit loss. If the insurer disputes the precise amputation level and whether a later revision or 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.
- NSW Guidelines para 1.24: the effect on activities of daily living must not be used to increase or reduce an upper-extremity impairment calculated under the applicable upper-limb method.
- NSW Guidelines paras 1.26 and 2.8: values are rounded at each conversion stage; digit impairment converts to hand impairment, hand and other regional values convert to upper-extremity impairment, and AMA5 Table 16-3 converts upper-extremity impairment to WPI.
- NSW Guidelines paras 2.5 and 2.20: active movement is measured with a goniometer or inclinometer, passive movement is recorded for clinical comparison only, unreliable readings should be repeated, and the uninjured opposite limb may provide the worker's normal baseline.
- NSW Guidelines paras 2.8-2.13: values within one joint are added, same-limb regional values must be expressed in a common unit before combination, a deficit caused solely by a peripheral nerve lesion is not also rated as abnormal movement, and strength is used only in rare permitted cases.
- NSW Guidelines paras 2.14-2.20 modify the shoulder, biceps, impingement, joint-surface fracture and epicondylitis methods in AMA5 Chapter 16; para 2.21 directs upper-limb CRPS to the NSW Chapter 17 method rather than an AMA5 Chapter 16 or Chapter 18 pain rating.
- NSW Guidelines para 2.4: maximum upper extremity impairment is 60% WPI, equivalent to amputation through the shoulder.
- NSW Guidelines Chapter 3 applies AMA5 Chapter 17 only as modified by NSW. Paragraphs 3.2-3.7 require the most specific valid method, selection of the highest valid evaluation where more than one method applies, common units before combination, and a 40% WPI lower-limb maximum.
- NSW Guidelines para 1.24: activities of daily living must not be used to increase or reduce a calculated lower-extremity impairment. Functional examples explain the measurement; they are not an extra percentage.
- NSW Guidelines paras 3.8-3.15 and corrected AMA5 Tables 17-4 and 17-6: true leg length, gait, unilateral atrophy and manual muscle testing each have their own measurement and non-combination requirements.
- NSW Guidelines paras 3.16-3.18: inconsistent range-of-motion findings are invalid; values from different movement planes within one joint are added; joint ankylosis uses the corrected NSW optimum-position table and positional additions.
- NSW Guidelines paras 3.19-3.24: arthritis means radiological cartilage loss for impairment purposes. It cannot be assumed from pain, and the arthritis method cannot be combined with gait, atrophy, strength or range of motion.
- NSW Guidelines paras 3.10-3.15 and 3.32-3.35: gait is a last resort; gait, atrophy, muscle testing and peripheral-nerve methods can duplicate lower-limb function and must follow Table 17-2 non-combination rules; CRPS uses the NSW Chapter 17 method rather than AMA5 Chapter 18 pain.
- NSW Guidelines paras 3.26-3.30 and Tables 3.2-3.4: NSW modifies diagnosis-based estimates, tibial plateau fracture, patello-femoral and ankle replacement, tibia-os calcis angle and persistent plantar fasciitis. Hip and total-knee replacements use AMA5 Tables 17-33 to 17-35 subject to the NSW corrections.
- Amputation values depend on the amputation level and whether the upper or lower extremity chapter applies.
Injuries and consequences that may need assessment
Amputation claims must identify the exact level: finger, thumb, hand, wrist, arm, toe, foot, below-knee, above-knee or other level.
- The assessment differs between upper extremity and lower extremity amputations.
- Phantom pain, prosthetic use, stump problems and consequential back or opposite-limb symptoms require separate evidence and may not automatically change the amputation table value.
Symptoms and findings that matter
The exact amputation level, side and structures retained determine which upper- or lower-extremity table and conversion sequence applies.
The stable residual limb, joint movement, nerve findings, scar or skin condition and any genuinely separate consequential condition should be documented without duplicating the amputation loss.
Prosthetic use, phantom sensation, work capacity and care needs may be important, but they do not replace the anatomical amputation method.
What investigations are usually relevant
Investigations for amputation may include emergency and operation records identifying the exact anatomical level and any revision surgery and stable surgical or rehabilitation examination of the residual limb, retained joint movement, skin and nerve function. Each result should answer a defined clinical question and be read with the examination, diagnosis and history.
- Prosthetic and occupational-therapy records describing fit, tolerance and function without treating device use as the table value.
- Separate evidence for any accepted opposite-limb, spinal, nerve or skin consequence proposed for additional assessment.
How WPI is assessed for this body part
Upper-limb amputation is assessed under NSW Chapter 2 / AMA5 Chapter 16, with a maximum upper extremity value of 60% WPI through the shoulder.
Lower-limb amputation is assessed under NSW Chapter 3 / AMA5 Chapter 17, with a maximum lower extremity value of 40% WPI for proximal above-knee amputation.
The assessor identifies the anatomical level in the applicable amputation table, performs each required digit, hand, upper-extremity or lower-extremity conversion and removes overlap with other methods.

Method illustration
This is a non-numeric illustration of the assessment sequence. It does not predict a WPI result.
- Accepted condition and findings
- Amputation claims must identify the exact level: finger, thumb, hand, wrist, arm, toe, foot, below-knee, above-knee or other level. The exact amputation level, side and structures retained determine which upper- or lower-extremity table and conversion sequence applies.
- Method to apply
- Upper-limb amputation is assessed under NSW Chapter 2 / AMA5 Chapter 16, with a maximum upper extremity value of 60% WPI through the shoulder.
- Why no percentage can be assumed
- The seriousness of the accident, hospital stay, prosthetic cost or inability to return to the former job does not change the anatomical table value by itself.
What usually does not increase WPI
The seriousness of the accident, hospital stay, prosthetic cost or inability to return to the former job does not change the anatomical table value by itself.
Phantom pain does not attract a separate AMA5 Chapter 18 addition in NSW workers compensation.
A scar, movement or nerve value cannot be added if it duplicates loss already represented by the amputation method.
A maximum value for amputation through the shoulder or proximal above-knee amputation is not the default for a more distal amputation.
Evidence checklist
The records for amputation should include accepted injury decision and operation records naming the exact amputation level and side and stable residual-limb, movement, skin and neurological examination after maximum medical improvement. They are most useful when the diagnosis, examination and practical restrictions are consistent.
- The applicable digit, hand, upper-extremity or lower-extremity table and every conversion step to WPI.
- Prosthetic and rehabilitation records for treatment and capacity questions.
- A non-duplication analysis for any separate nerve, scar, joint or consequential condition.
How this injury commonly happens at work
Work-related amputation can arise through machinery entanglement, crush or cutting equipment causing traumatic limb or digit loss and a vehicle, mobile-plant or falling-load incident producing an amputation or later medically required removal. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related amputation can arise through an accepted wound, vascular injury or infection that leads to surgical amputation. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For amputation, an insurer may dispute the precise amputation level and whether a later revision or consequential condition is accepted and whether a prosthesis, replacement component, wound treatment or rehabilitation is reasonably necessary. The written decision should be answered with evidence directed to those reasons.
Further disputes about amputation may concern whether proposed duties account for residual-limb tolerance, protective sensation, balance, dexterity and fatigue and whether separate scar, nerve or joint values duplicate loss already represented by the amputation method. 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 amputation may involve wound healing and any supported revision or reconstructive surgery and prosthetic assessment, fitting, replacement and residual-limb management. The request should explain the expected functional benefit and its connection to the accepted injury.
Further management of amputation may involve physiotherapy, occupational therapy, desensitisation and functional retraining directed to safe work and daily activities. 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 amputation should address prosthetic tolerance, walking distance, balance, stairs, uneven ground or transfer ability for lower-limb loss and grip, pinch, protective sensation, tool control and bilateral task demands for upper-limb or digit loss. Proposed duties must be sustainable for the proposed hours, not merely possible once.
For amputation, capacity evidence should address attendance, skin breakdown, treatment, pain and fatigue across the actual roster. 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 amputation, a claim review can help to confirm the accepted amputation level and every supported consequential condition and organise stable prosthetic, residual-limb and functional evidence. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
For amputation, a claim review can help to check the impairment calculation and proposed duties for overlap and real-world sustainability. 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 amputation claims
How can work cause or aggravate amputation?
For amputation, the relevant work history may include machinery entanglement, crush or cutting equipment causing traumatic limb or digit loss, a vehicle, mobile-plant or falling-load incident producing an amputation or later medically required removal, and an accepted wound, vascular injury or infection that leads to surgical amputation. 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 amputation?
For amputation, upper-limb amputation is assessed under NSW Chapter 2 / AMA5 Chapter 16, with a maximum upper extremity value of 60% WPI through the shoulder. The exact amputation level, side and structures retained determine which upper- or lower-extremity table and conversion sequence applies. 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 amputation assessment?
An amputation assessment commonly needs accepted injury decision and operation records naming the exact amputation level and side, stable residual-limb, movement, skin and neurological examination after maximum medical improvement, the applicable digit, hand, upper-extremity or lower-extremity table and every conversion step to WPI, and prosthetic and rehabilitation records for treatment and capacity questions. 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 amputation?
For amputation, common issues include the precise amputation level and whether a later revision or consequential condition is accepted, whether a prosthesis, replacement component, wound treatment or rehabilitation is reasonably necessary, and whether proposed duties account for residual-limb tolerance, protective sensation, balance, dexterity and fatigue. 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 amputation affect weekly payments and suitable duties?
Capacity evidence for amputation may need to address prosthetic tolerance, walking distance, balance, stairs, uneven ground or transfer ability for lower-limb loss, grip, pinch, protective sensation, tool control and bilateral task demands for upper-limb or digit loss, and attendance, skin breakdown, treatment, pain and fatigue across the actual roster. 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.
What does not establish WPI for amputation by itself?
For amputation, the seriousness of the accident, hospital stay, prosthetic cost or inability to return to the former job does not change the anatomical table value by itself. WPI depends on the accepted injury, objective findings and the method required by the NSW Guidelines after the condition has stabilised.
