Payer schedules and available estimation tools allow providers to communicate the patient’s financial obligation expected at time of service. Typically occurring during the registration process, PreServices can be as basic as a courtesy call to remind patients of their appointment and financial obligation at time of service. On the other hand, PreServices can be as advanced as complete pre-registration with estimated charges collected before the patient arrives for their scheduled procedure. In both examples, Self Pay dollars are collected BEFORE time of service, minimizing the amount of Self Pay dollars to be collected later. Added benefits are increased patient satisfaction by decreasing on-site check-in times, and increased physician satisfaction due to decreased interruptions in scheduling.
