Understanding injury claim terms
This guide explains why impairment assessments arise, what information an assessor may need and how the concept differs from work capacity and treatment. Scheme-specific thresholds and methods require current, individual checking. This is general information only. The position depends on the claim pathway, facts, evidence, dates and current law or policy wording.
Permanent impairment is a medical-legal assessment of lasting impairment under the rules for a particular scheme. It is not the same as pain, diagnosis, disability, inability to work or a guaranteed lump sum, although those issues may use overlapping evidence.
A percentage cannot be estimated from a website, diagnosis or scan alone. Different schemes may use different methods, and permanent impairment does not by itself decide every entitlement, work capacity issue or TPD claim.

Check whether the condition is sufficiently stable, which body system and guideline apply, what objective findings are recorded, whether earlier conditions are relevant and what exact question the assessor was asked to answer.
Start with complete source records rather than a label or summary. Keep specialist reports, imaging, operation records, treatment history, examination findings, certificates, prior relevant records and the assessment request. A clear functional history can help explain the medical material but does not replace objective assessment.

Do not treat an early estimate as final, confuse a work-capacity certificate with an impairment assessment, or attend without checking the records and body areas being assessed. Keep the original decision or source document and separate confirmed facts from assumptions.
Prepare a short chronology, identify the decision or question causing concern and send only the key records first. If a response date is stated, do not wait for every document before asking what to do next. Check whether the condition is sufficiently stable, which body system and guideline apply, what objective findings are recorded, whether earlier conditions are relevant and what exact question the assessor was asked to answer.

The useful records depend on how the injury happened, when symptoms were recorded and how treatment or work capacity changed.
Common questions
Short general answers only. The right next step depends on the facts, dates and documents.
No. Impairment is a medical-legal measure. Work capacity considers what work a person can perform and may change over time. The two questions can use related evidence but should not be treated as identical.
Keep specialist reports, imaging, operation records, treatment history, examination findings, certificates, prior relevant records and the assessment request. A clear functional history can help explain the medical material but does not replace objective assessment. Keep dates, authors, attachments and the complete wording so the material can be read in context.
A percentage cannot be estimated from a website, diagnosis or scan alone. Different schemes may use different methods, and permanent impairment does not by itself decide every entitlement, work capacity issue or TPD claim. It organises the issue but does not predict or guarantee a result.
Check whether the condition is sufficiently stable, which body system and guideline apply, what objective findings are recorded, whether earlier conditions are relevant and what exact question the assessor was asked to answer. Seek prompt advice if you have a rejection, payment change, settlement proposal, missing records or a stated response or review date.
Injury pathway enquiry
Start with how the injury happened, what medical records exist and how work or daily activity has changed. The same injury can sit in different pathways.
