Determining the provider’s legal name

Q: What is the provider’s legal business name that should appear on CMS-855 Medicare enrollment applications?
A: A provider’s legal business name is the name that is registered with the Internal Revenue Service (IRS) and should appear on IRS documents, such as the CP-575, that contains a provider’s employee identification number (EIN) or tax identification number (TIN).
The provider’s legal business name with the IRS should identically match (including any or no punctuation) the business name registered with the National Plan & Provider Enumeration System (NPPES), which issues the national provider identifier (NPI). This is the information that will be loaded into the Provider Enrollment, Chain and Ownership System (PECOS). PECOS and NPPES must match exactly.
To validate that the legal business name the IRS has for you matches the business name registered with NPPES by visiting the NPPES website external link or contacting them at 1-800-465-3203 or 1-800-692-2326 for TTY services.
