NDC- Medicare

    Default NDC- Medicare

    Has anyone had trouble billing Medicare and using NDC format? Keep getting rejects for invalid format... reject reads must be 5-4-2 format no hyphens. We have billed with no hyphens, extra digit in front, and with hyphens.

    There must be an N4 in front of the number with no space and you substitute 0 for the dashes and make sure the number is 11 digits exactly so they the N4 plus the number will equal 13 characters

    Our NDC for example is 55555-4444-22 so take out the - and add zero's correct? So it would be 5555504444022? then put N4 in front? That makes it 14 digits. Did I understand correctly/right? Thank you for your help

    you can only have 13 total so you would leave the 0 s out in your example. The number itself can be only 11 digits. Then you put the N4 in front so N455555444422
