Overview
Start with the injury that is driving the decision or treatment problem
Choose the guide closest to the diagnosis, body part or psychological condition now affecting work capacity, treatment or weekly payments. If more than one injury is involved, start with the one linked to the insurer decision, surgery request, certificate of capacity or WPI issue you need to answer.
May have a claim
The legal test depends on the injury type. A personal injury generally requires employment to be a substantial contributing factor; a disease contracted or aggravated after the 2012 amendments generally requires employment to be the main contributing factor.
Benefits to check
Treatment expenses, weekly payments, suitable duties, WPI and dispute options.
Evidence to collect
Incident records, GP notes, scans, specialist reports, capacity certificates and actual duties.
Current process
Permanent impairment assessments from 1 July 2026 to mid-2027
NSW is in an interim period. Separate examinations arranged by the worker and insurer can still occur, but an interim assessment must be performed by an assessor on SIRA's register. Liability for the injury must have been determined before an interim assessment is made.
Independent legal advice is compulsory
A worker must receive independent legal advice about the full legal implications before being seen by a permanent impairment assessor. Advice is also required before entering an impairment agreement.
The assessment can affect several entitlements
The principal assessment is used across weekly payments, medical and related treatment expenses, Section 66 lump sum compensation, commutation access and work injury damages. It is not only a lump sum calculation.
Agreement or medical dispute
If the worker and insurer agree on the degree of impairment, they may enter a written impairment agreement. If they do not agree, the insurer must give written notice and either party may refer the disagreement to the Personal Injury Commission as a medical dispute, supported by medical evidence.
A further assessment is tightly restricted
A second or later assessment during the interim period requires agreement that there appears to be unexpected and material deterioration. The deterioration must be capable of increasing the impairment by at least a further 10 percentage points. Ordinary age-related deterioration does not meet that test.

Injury-specific NSW workers compensation guides
These pages are grouped by body part and injury type. They help injured workers identify the documents and questions that commonly matter: work cause, treatment approval, weekly payments, suitable duties, permanent impairment and insurer disputes.
For the broader claim pathway, start with the statewide NSW workers compensation lawyers guide. If you already have an injury diagnosis, use the guides below to focus the evidence without treating the diagnosis alone as the answer.
How permanent impairment information should be read
The injury guides use the NSW Workers Compensation Guidelines for the Evaluation of Permanent Impairment and, where adopted, AMA5. The NSW modifications prevail. A diagnosis, pain score, scan finding or operation name does not establish WPI by itself; the applicable body-system method, measurable findings, maximum medical improvement and any supported deduction must be addressed.
For example, a lumbar disc finding is not assigned a percentage merely because it appears on MRI. NSW spinal assessment uses the DRE method and looks for the supported category findings, including objective radiculopathy where alleged. This example explains the method only and is not an estimate of another worker's result.

Evidence checklist before choosing a guide
Before relying on an injury-specific page, collect the practical documents that usually shape a NSW workers compensation decision: the incident report or work task description, certificates of capacity, GP and specialist notes, imaging or test results, treatment requests, payslips or pre-injury earnings material, and any insurer letters explaining acceptance, denial, work capacity or treatment decisions.
If the injury developed over time, write down the repeated duties, dates symptoms changed, when work was first reported as a cause, and any non-work factors the insurer may raise. This helps match the right guide to the real dispute rather than relying on the diagnosis label alone.
Practical first steps when the injury is disputed
If the insurer disputes whether work caused the injury, start by comparing the decision reasons with the medical timeline. Check whether the treating doctor has recorded the work incident, repeated duties or exposure clearly, and whether any imaging, specialist report or psychological assessment answers the exact issue the insurer raised.
If treatment, surgery, weekly payments or work capacity is the problem, keep the injury guide focused on that decision. A treatment dispute usually needs clinical reasons and prior treatment history; a weekly payment or capacity dispute usually needs certificates of capacity, suitable duties details, earnings information and the medical restrictions that explain what work is safe.
For the full claim sequence, cross-check the make a claim guide, the weekly payments guide and the workers compensation disputes guide. This page helps you choose the injury topic; those guides explain the broader NSW process.
Back, spine, and neck
Back, neck, spinal, nerve-root, pain and surgery-related claims.
Shoulder, arm, and hand
Shoulder, elbow, wrist, hand, nerve, tendon and overuse injuries.
Hip, leg, knee, ankle, and foot
Hip, pelvis, leg, knee, ankle, foot and lower-limb surgery issues.
Head, brain, face, and neurological
Head, brain, face, jaw, dental, eye, vestibular, nerve and chronic pain conditions.
Psychological injury
Psychological injury claims can involve section 11A and NSW reform issues, so the notice, chronology and medical evidence need careful document-based assessment.
Occupational disease and exposure
Disease, exposure, hearing, respiratory, skin, infection, heat and vibration-related conditions.
Serious and traumatic injuries
Traumatic, catastrophic and multi-system injuries needing long-term evidence planning.

These existing guides remain linked while the broader injury library expands.
