What does “tentative appointment” mean?
It is a requested time, pending Keystone’s review. Your appointment becomes confirmed only after the practice reviews registration, clinician fit, and insurance or payment arrangements and contacts you with confirmation.
Why do I need two days’ notice?
Please allow at least 48 hours so Keystone has time to review your registration and prepare for your first appointment.
Do I need to complete registration first?
Yes. Complete and submit the client registration form before requesting a time. Keystone checks your registration before confirming an appointment.
