A provider’s legal business name (LBN) is the name that is registered with the IRS and appears on IRS documents, such as the CP-575, that contains a provider’s EIN or TIN. This is the name that should be put on the CMS-855 application.
The provider’s legal business name with the IRS must also match (including any or no punctuation) the business name registered with the National Plan & Provider Enumeration System (NPPES), which issues the NPI. The LBN will be loaded into PECOS,
To validate that the legal business name the IRS has for you matches the business name registered with NPPES visit the NPPES website or contact them at 1-800-465-3203 or 1-800-692-2326 for TTY services.
