This reference section contains any lab codes associated with the Canadian Dental Association. This section is utilized in conjunction when Canadian Claim Fields are enabled in your localization preferences (located in the MacPractice menu).
If you don't have the Localization Preference "Use Canadian Claim Fields" enabled, then this reference will not have an impact on MacPractice.
If the Preference "Use Canadian Claim Fields" is enabled, any codes and corresponding fees entered into this reference will be available in the Charge Window of the Ledger. You'll simply need to click the plus button above the "Lab Code" table.
In the Charge Window, you can use the "Add Lab Fees in Patient Portion" checkbox to add any corresponding fee to the patient portion of the charge.
