A healthcare administration system integrates the entry of an order for a medical service for a patient with the scheduling of an appointment for performing the service. The system incorporates receiving service order information for a medical service for a patient from a user; generating an order for the medical service based upon the service order information; and enabling the user to perform one or more tasks selected from the group consisting of (a) scheduling an appointment with a provider of the medical service, (b) storing the order information in a queued waitlist, and (c) automatically rescheduling the appointment based upon the queued waitlist.
