In order to bill a National Drug Code (NDC) on a claim, you'll need to first take the following steps:
- Add the NDC to your Billing codes database
- Tie your NDC to the service code
- Bill the service code, selecting the NDC and associated units
(1) Add the NDC to your Billing codes database
Navigate to your Billing Codes Database and click the Add button.

Under the New Clinic Billing Code section, select National Drug Code.
Enter the 11 digit NDC (or 13 digit, following the xxxxx-xxxx-xx format)

Click Add to save the code.

(2) Tie your NDC to the service code
Navigate to the service code to which you need to tie the NDC. (or add the service code if you haven't already - whether that is a HCPCS Custom Code or a CPT code).
Edit the code and select the Drug Code field and enter the specific NDC into the National Drug Code field.

Remember to click Save!

(3) Bill the CPT code on a purchase
When you add the CPT code to a purchase, you'll see the associated NDC populate, with the option to indicate NDC Units and Unit type.

Upon claim generation, the NDC will appear on the claim:

💡Pro-Tip:
Need to use multiple different NDC for one CPT code?
If you have multiple drugs that use the same CPT/HCPCS code but have different NDCs, you do not need to create duplicate billing codes.
Instead, add all of the applicable 11-digit NDCs to your Billing Code Database and associate the most commonly used NDC with the CPT/HCPCS code.
When billing from a purchase, you can select the appropriate NDC for that specific patient by opening the NDC dropdown on the billing code and choosing the correct NDC.
