There is no single catastrophic-impairment test
The applicable route depends on the injury, the person’s age, the accident date and the available assessment tools. Some criteria rely on defined medical scales or whole-person impairment methods. Others address specific injuries or functional outcomes.
The legal and clinical team should identify the possible criterion early, while being honest about whether the condition is sufficiently stable and whether a required assessment period has passed.
The OCF-19 should identify the route and the professional evidence supporting it
The prescribed OCF-19 is the application for a determination of catastrophic impairment. FSRA publishes the current form.2 The form and accompanying assessments should address the specific regulatory language rather than simply describe the injury as severe.
Organize the application around
- The exact SABS criterion or criteria relied upon
- The professionals qualified to perform the required assessments
- The accident, medical and functional chronology
- The measurements, records and assumptions used
- Any timing requirement or reason for an earlier application
A designation can materially expand available treatment and care funding
Catastrophic impairment can change the limits and availability of medical, rehabilitation and attendant-care benefits. It may also affect access to certain optional benefits, depending on the policy and current regulation.
The designation does not guarantee that every proposed service will be funded. Treatment, assessment and attendant-care claims still have to meet the applicable SABS requirements.

A denial should be tested against the criterion, assessment record and reasons
Keep the OCF-19, all supporting reports, insurer-examination material and the explanation of benefits. Identify whether the dispute concerns the criterion, methodology, permanence, timing, causation or sufficiency of evidence.
Disputes about accident-benefit entitlement are generally brought to the Licence Appeal Tribunal’s Automobile Accident Benefits Service.3
How a personal injury lawyer may help with accident benefits.
A useful review should reduce the file to a defined benefit, disputed period, governing test and evidence problem—then explain the available response in plain language.
- Identify the benefit, policy, insurer and legal test that apply.
- Answer the denial with medical, functional and financial evidence.
- Protect application, examination, LAT and reconsideration deadlines.
