Registrars are a critical resource in the revenue cycle.  The information gathered by a registrar constitutes 50% of the claim information submitted to a third-party payer for reimbursement.  The completeness and accuracy of their work has a direct impact on the hospital's cash flow and the patient's customer experience related to a hassle-free billing process. Registrars register patients for inpatient and outpatient services throughout the hospital.  The process includes gathering information from patients, validating received information with insurance carriers, determining benefits, estimating out of pocket costs for the patient, and completing forms with the patient in accordance with federal and state regulations.
