Workers Compensation (WC) claims may be underpaid and too costly to appeal. WC claims are documentation and labor intensive which makes them very costly to pursue in house. Many times, these claims involve multiple parties such as the carrier, patient, employer and state agencies. Most states and all payers have complex fee schedules, usual and customary reimbursement laws, or contractual guidelines for payment. Often, hospitals are overwhelmed with insufficient resources and staff to deal effectively with the intricacies of these claims. HLS computes the lawful payable, bills the payer and files appeals for these claims which are almost always underpaid.
