When scanning the square 2D Matrix barcode on vaccines, we have found the lot number field in EPIC is populated with the lot number...plus a long string of extra digits. If those extra digits are not manually removed, it creates inventory discrepancies with our state-supplied vaccines (which look for an exact match for lot number).

For background: We are scanning the outer box 2D matrix barcode, and documenting administration using the EPIC immunization activity.
