Providing the right CAT Assessments

A Catastrophic Impairment Assessment (CAT) is a term used to determine the severity of one's injuries, mostly in motor vehicle accident victims.

People with physical, neurological, mental, behavioral, vascular, visual, spinal cord or neurophysical disabilities as a result of motor vehicle trauma often need access to funding for their rehabilitation and care over their lifetime. For that matter, claimants with injuries meeting the Catastrophic Impairment definition requirements might have greater level of benefits for their medical and rehabilitation goods and services, as well as attendant care and case management (that could be up to the millions).

Thanks to CAT assessments, the claimant will see if they are entitled to catastrophic level of funding. The assessment basically evaluates the entire mental, physical and behavioral state to determine the condition of the patient and see if the injuries are affecting their lifestyle and ability to work.
