Independent medical examiners: what they do and how to brief one
The impartial opinion for contested questions — and the referral discipline that determines whether the report is worth its fee.
An independent medical examiner is a doctor with no treating relationship to the claimant, engaged to provide an impartial opinion on diagnosis, capacity, treatment or causation for a claim. Their report carries weight precisely because they don't treat the patient — and its usefulness is set almost entirely by the referral they receive.
Key Takeaways
- Independent means non-treating: the examiner’s value is the absence of a treating relationship — an impartial second opinion for contested questions
- Scheme rules apply: each Australian jurisdiction governs when insurers may arrange IMEs, examiner selection and worker protections
- They answer what they’re asked: the referral letter’s questions and attachments determine the report’s usefulness
- Medication questions need the history: an examiner can’t assess a regimen they can’t see — attach the reconciled dispense history
- Specialty matters: match the examiner to the question — occupational physician for capacity, pain specialist for regimen questions, psychiatrist for psychological injury
Where an IME earns its place on a claim
- Contested capacity: certificates and the employer's reality disagree, or certificates have rolled unchanged while treatment escalated
- Treatment reasonableness: whether specific treatment — including a medication regimen — remains reasonable for the compensable injury
- Causation and scope: whether conditions being treated relate to the compensable injury
- Permanent impairment: scheme-specific assessments at the claim's settlement points
Scheme rules for arranging examinations — frequency limits, notice, worker protections — are published by the regulators: SIRA, WorkSafe Victoria, WorkSafe Queensland, Comcare.
The briefing discipline
Examiners consistently report the same two referral failures: questions too vague to answer ("please assess") and material too thin to answer them with. The fix costs a page: specific questions, and the evidence those questions depend on. For medication questions that means the reconciled dispense history — the examiner sees the claimant for an hour and cannot reconstruct a multi-prescriber regimen from an interview.
