CorVel has carved out a niche providing medical cost containment for workers' compensation programs, auto insurers, and group health plans. CorVel helps insurers, third-party administrators, and self-insured employers keep down costs associated with workers' compensation and other medical claims and to get employees back on the job as soon as is practicable. Among other things, CorVel reviews medical bills to make sure they are in line with state fee schedules, using its automated online MedCheck software. It also maintains a preferred provider organization (PPO) and provides case management and vocational rehabilitation services. Clients access CorVel's range of services through its CareMC Web portal.
