Add-on codes are added to appointments or charges to describe services that are performed in conjunction with the primary code. Add-on codes can include different services but are commonly used for diagnostic services. The Valant EHR can support up to 15 Add-on codes for appointments added through the calendar, and up to 50 Add-on codes on the Create Charges page.
Add-on Codes in Valant
Watch a brief demonstration of the appearance of add-on code function with more than two allowed. Initially a field for Add-on Code 1 will appear below the Primary Code field. Once an Add-on Code field is populated, a new field will appear. Up to 15 are allowed in locations in which the option appears, except for Create Charges which allows up to 50 per X12 standard.
How to Use Testing Add-on Codes
When billing insurance payers and Medicare for psychological and neuropsychological testing services it is typically required that you would bill a primary code for the first hour of services and then another Add-on code for each additional 30 or 60 minutes of evaluation of services or test administration.
