To manually enter a Record Number, make changes directly in the Record Number field and click Save.
To move the Patient Record Number, you can cut-and-paste it from one chart to another. Highlight the number and save to your clipboard (CTL+X) and click Save. Then proceed to add this PRN to another patient chart in the same way.
Note: If you are using the same PRN system in your billing software, you may want to update the PRN within the billing system as well.
