Yes, FastEMC offers full support for the National Provider Identifier. Starting with HCFA ANSI 8.04 and UB ANSI 8.03, FastEMC also added a stop date for legacy identifiers to comply with NPI-only standards that some payers, including Medicare, have mandated. Before you start submitting claims without legacy identifiers, you should check your provider file to make sure that the identifier for your tax ID (either E for employer identification number or S for Social Security number) matches your NPI registration.
