Getting Ready

In order to be paid, all physician offices must change their electronic data interchange. In order to do this, register on the NGS website.

If you contract with a billing company, check with your billing company to ensure that it has taken the steps to make your office compliant with the new system.

If you do your own billing, and you used the free NHIC software, you must convert to the NGS free software program. Click here for more information about the new software program.
