When a person has met the eligibility criteria, they are considered an "eligible claimant" of the CAT Fund.​ 

CAT Fund benefits are provided to eligible claimants for the payment of medical and rehabilitative services, more than $100,000, which are medically necessary, reasonable, and accident-related. The claimant must provide proof that the first $100,000 of medical expenses have been paid.

The maximum benefit paid by the CAT Fund on behalf of anyone eligible claimant is $50,000 per annual limit year with a $1,000,000 lifetime aggregate. During the first 18 months after the motor vehicle accident, benefits are provided without regard to the $50,000 per annual period limit but subject to the $1,000,000 lifetime aggregate.
