Medisanitas members' appointments, in Microsoft Outlook. With Arbol, with no manual copying.
How it works
The Medisanitas member calls or writes to your organization.
The assistant tells them their Medisanitas plan's coverage and copay using what your clinic has loaded.
It checks availability in Microsoft Outlook and creates the appointment as an event on the clinician's calendar.
If the patient reschedules, it moves it in Microsoft Outlook and lets your team know.
