Can you change the time increments in the Appointment Book from 15 minutes to 10 minutes? Or, if they are already at 10-minute increments, can you change them to 15-minute increments?

The short answer is, yes, but there are a couple of behind-the-scenes adjustments that need to happen at the same time.

Note: It is best to make these changes when everyone is out of Dentrix, either before or after business hours. If changes are made during the workday, after you’ve finished making changes, have each computer close and reopen the Appointment Book to ensure changes are updated throughout the network.

To change the time block increment, in the Appointment Book, go to Setup > Practice Appointment Setup. Under Time Block Size, set the size of the increment you want to see in your Appointment Book and click OK.

When you do that, you will see a warning telling you that by adjusting the increment, some appointment times will become invalid, and you’ll have to edit individual appointments. Click OK to acknowledge that you understand you will have to edit or move appointments.

So what does this mean? If you were previously using 15-minute increments, and switch to increments of 10 minutes, then any appointments that were scheduled at :15 or :45 after the hour no longer have valid starting times. Those appointments will have to be moved to fit within your new 10-minute increments in the Appointment Book.

As you look through your scheduled appointments, you will notice that some of them are now positioned in between time slots. When you touch those appointments with your mouse, a warning will appear asking if you want to move the appointment. Click Yes to move the appointment to the nearest time slot increment.

Important: If you change time increments, take the time to immediately go and move each scheduled appointment in the Appointment Book to a new increment, so that any appointment confirmation services you are using have accurate information.

Also, be aware that procedure code setup and multi-code setup in Dentrix also use these time block units. Each procedure in Dentrix is assigned a number of procedure time units that it takes to complete. To view or change a procedure’s time units, from the Office Manager, click Maintenance > Practice Setup > Procedure Code Setup. Select a procedure code category and individual code, and then click Edit.

In the above example, you can see that code 11101 is set to 2 Units of Procedure Time. If you are using a 15-minute time increment, this procedure will result in a 30-minute appointment, but if you have changed to a 10-minute time increment, this procedure will result in a 20-minute appointment.

So, think about the amount of time each procedure typically takes to complete in your practice, and what your Appointment Book time block settings are. Is this an accurate amount of time to allot for the procedure? If you need to make adjustments to the time units, click the > button and edit the time as needed. Save your changes and repeat with other procedure codes as needed.
