Within the EHR a practice can choose to enter in the NDC, Unit and Unit Type data for Immunization, Test Codes, and Injection. Previously, the system only passed in the NDC for CPT codes beginning with J.  First, this feature it must be enabled in Global Settings:

Then, in Immunization, Test Code and Injection Admin enter the Associated NDCs, Unit Type and Dose per Unit. Note: For Immunizations the information entered into 'Dose' will be used for Unit and Unit Type. 

This information will then get passed through to the Charge Posting Interface and included on claims.
