Clarification on VIS Barcode Handling in NIST Validation Tool and ONC Certification Requirements

[Jyothi Yella]

Hi team,

While testing with the NIST immunization validation tool, we observed that VIS documentation can include a GS1 barcode value in the OBX segment, for example:

e.g., - (OBX|3|CE|69764-9^Document Type^LN|3|253088698300017211250131^Polio Vaccine VIS^cdcgs1vis||||||F|||20150624)

In this case:

• 253088698300017211250131 is the GS1 barcode identifier for the specific Polio Vaccine VIS document.

• The code system cdcgs1vis indicates it is from the CDC GS1 VIS barcode list.

We would like to confirm:

1. Do we need to support capturing and transmitting the VIS barcode in our system?

2. Is this functionality required for ONC Certification, or is it optional as long as VIS type, edition date, and presentation date are recorded?

Your guidance will help us determine if this needs to be included in our implementation scope.

Regards,

Jyothi
