# Update an Existing Appointment
Before starting a consultation, you may need to update the Appointment or Case Type.
### Change the Case Type
**Add an Existing Case Type**
**Enter existing Case Type:** Open the appointment → click the **Edit** icon → select the Case from the drop-down in the Case bar.
**Create a New Case Type**
**Create a new Case Type:** The only required field is **Case Name**. However, because insurance is required on the Appointments page, we recommend setting the **Insurance Priority** as well.
