The first step in initiating a claim for workers compensation benefits is to file a Petition for Benefits (PFB). A PFB is much like a complaint in a civil litigation matter because lists specific benefits that the claimant is entitled to, including lost wages, medical expenses, prescription medications, mileage for trips to and from the authorized medical provider, physical therapy, and more. The insurance carrier has 14 days after the submission of a PFB to either pay the requested benefits or file a response to the claimant.
