In TiQ you have the ability to add the same code(s) with a different service fee(s), here's how to do so:
Under Practice Manager select the Services & Tags tab

Scroll to Services Setup

Select the + Add More button

In order to add a service with an identical code you must alter the code so the system recognizes the codes as something different. You can do this by utilizing dashes(-) and different words when creating the services.
Example:

Enter the Full Service Fee

Select the Service Type

Select Submit to save
