Understanding Unit Billing and using Multiple CPT Codes in SimplePractice

Our Unit Billing feature gives you the power and flexibility to select which service codes you want to bill in units, instead of or in addition to time. This will allow you to automatically and effortlessly populate the correct number of units onto your superbills and/or claims. 

This feature also allows customers to add multiple CPT codes to the same appointment without having to create multiple appointments. Below you'll find steps for using this feature successfully from your laptop, desktop, mobile device, or tablet.

Enabling Unit Billing in your account

  • Go to My Account > Settings > Billing and Services:  
    • Flipping the switch here to enable Unit Billing will then allow you to navigate to your Services page:
    • You will now see a new Unit Billing checkbox for each service code on your Billing and Services > Services page:
    • When adding a new code or editing an existing one, you will see this new checkbox: Bill this code in units
      • if the Bill this code in units box checked, the Rate field changes to Rate per unit:
      • You can set the Rate per unit for each code that you choose to bill in units.

Note: If the Rate per unit is applied to an existing service, this change will only be applied to appointments that are created after the edit and will not affect existing future appointments.

Tip: The Default Service Duration is used to reflect the length of time a service blocks off on the Calendar. It does not automatically impact the number of units billed on claims. For detailed information, please see this guide: What is the Default Service Duration?

Creating an appointment to bill in units

When you create an appointment and a unit-billed code is selected, you will see:

  • The code
  • The number of units (default is 1 unit)
  • The Rate per unit
  • The Total rate fields

  • From here you can adjust...
    • The Total rate by increasing the number of units
    • The Rate per unit for this appointment
    • The Total rate
      • If you adjust this, the number of units and Rate per unit calculation will be disconnected 
        • You can reset this if needed

Note: You'll want to double-check that you're billing the correct units by reviewing the details after you've held the appointment with your client. Due to the needs of different specialties, the default is always 1 unit. We are considering adding enhancements to this option in the future.

Tip: If you're not sure which service(s) a client will need before you see them, you can create a custom service code to serve as a placeholder until after the appointment. After you've held the appointment with the client, you can go back and edit the service(s) to accurately reflect the services you provided.

Adding Multiple CPT Codes to an appointment

You will also see that you have the ability to add other services onto this appointment. This allows you to use multiple primary codes as well as multiples of the same add-on codes for appointments.

  • For subsequent primary codes added, it will default with the base unit fee and 1 unit. 
  • If you add three or more CPT Codes to an appointment, you will have the options to rearrange them and to delete them.
    • To rearrange the position of the CPT Codes for a client's appointment, use the arrow icons to drag and drop them into the correct order:
    • To delete a CPT code from a client's appointment, click the trashcan icon:

Note: Once an appointment has been created with units, any and all units added will automatically be added to any claims created.

Tip: The first CPT Code added for an appointment is considered the original service and cannot be rearranged. If you need to rearrange the position of the first CPT Code, you will need to delete the appointment from the Calendar and then create a new appointment with the correct order of services.

Note: Currently, the maximum number of CPT codes that can be added to an appointment is 6.

Adding a unit-billed service as a client's default service

To add a unit-billed service as a client's default service, go to the Client Overview Page > View/edit client info > Billing and Insurance tab

The default unit-billed service code will support the Rate per unit for the client and the number of units will default to 1.

Note: Non-unit-billed codes will continue to work the same way, but only for the first code added to an appointment.

Documenting and billing with Unit Billing and Multiple CPT Codes

When Unit Billing and Multiple CPT Codes are enabled for your appointments, you will see some changes to statements, claims, and the Appointment Status Report with clients you've chosen to bill this way.

  • Here is an example of a statement for a client whose appointment has been billed in units and with Multiple CPT Codes:
