Use custom codes for any service code that isn’t in the CPT code library, such as HCPCS codes or codes your office uses for cash-based services. 

✏️ Here's how to add a custom billing code: 

1. Go to Databases > Billing Codes. 

2. Click the +Add button. 

4. Under Create your own, select Service. 

5. Proceed with entering your custom code, description, and billed amount. 

Optionally enabled variable billed amount to allow for the billed amount to be changed anytime the code is billed. 

6. Finish by optionally entering any alternate descriptions, default modifiers, and indicate if its a drug code (linkable to an NDC) or default non-billable.

If this code has any payor-specific rules, like allowed amounts or payor-specific modifiers, enter those below by first searching for the payor. 

7. Don't forget to click Save!
