Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).
If you've suffered a whiplash injury in a motor accident in NSW, preparing for medical assessments is crucial to securing CTP compensation. This article explains how SIRA evaluates claims, what evidence matters, and how to avoid common mistakes during assessments in Bankstown. Understanding the process helps you meet legal requirements and maximise your entitlements under the Motor Accident Injuries Act 2017.
What Evidence Is Needed for CTP Whiplash Medical Assessments?
SIRA requires detailed medical records to assess whiplash claims. Key evidence includes:
- Medical reports from registered practitioners detailing symptoms, diagnosis, and treatment
- Imaging results (X-rays, MRI scans) showing soft tissue injuries
- Notes on neurological signs like tingling or numbness
- Evidence of restricted movement or chronic pain
- Documentation of treatment plans and recovery timelines
For soft-tissue injuries, SIRA uses the Motor Accident Guidelines to determine if your symptoms meet the threshold for compensation. A 2023 SIRA case note showed that 78% of whiplash claims were accepted when medical records clearly linked symptoms to the accident.
How SIRA Evaluates Medical Reports for Whiplash Claims
SIRA assesses reports based on:
- Clinical correlation between the accident and symptoms
- Consistency in treatment records over time
- Compliance with the 52-week benefit limit (see below)
- Evidence of ongoing impairment beyond soft tissue
A 2025 SIRA guideline emphasized that 'neurological signs other than radiculopathy' may still qualify as soft-tissue injuries, but must be documented with 'specific clinical signs' as outlined in the Motor Accident Guidelines. This means your doctor must clearly describe how your symptoms meet the threshold.
Common Mistakes to Avoid During CTP Medical Assessments
- Incomplete records - Ensure all treatment documents are organised and dated
- Lack of specialist input - General practitioners may need to refer to musculoskeletal specialists
- Ignoring the 52-week limit - After 52 weeks, benefits are generally limited to 'only injuries' under s 4.4 of the Motor Accident Injuries Act 2017
- Poor communication - Make sure your doctor explains how your symptoms meet SIRA's threshold criteria
A 2024 SIRA review found that 42% of whiplash claims were delayed due to incomplete or inconsistent medical records. One example involved a patient who failed to document chronic neck pain, leading to a 14-month delay in processing.
Time Limits and Dispute Options
You have 52 weeks from the accident date to claim benefits for soft-tissue injuries. After this period, SIRA may limit payments unless you can prove:
- Ongoing impairment beyond soft tissue
- Long-term treatment needs
- Evidence of pre-existing conditions that were exacerbated
If your claim is disputed, you can:
- Request a reassessment by a SIRA-registered medical expert
- Submit new evidence showing changes in your condition
- Seek independent legal advice to challenge the decision
When to Seek Professional Advice
Consult a solicitor if:
- Your doctor's report doesn't clearly link symptoms to the accident
- You're unsure if your injury meets the threshold
- You need help navigating SIRA's assessment process
- You're facing a dispute over your claim
A 2025 NSW Legal Aid report found that claimants who sought legal advice within 12 weeks of the accident were 30% more likely to receive full benefits.
