What documentation is considered acceptable regarding the verification of my National Provider Identifier (NPI)?


Answer:
The CMS 855S enrollment form requires each supplier to furnish its NPI in the appropriate section(s) and submit a copy of the notification received from the National Plan and Provider Enumeration System (NPPES) verifying the NPI.

CMS considers the following to be acceptable NPI notifications:

  • NPI notification letters from the NPPES. These notifications are sent to suppliers who applied for the NPI by completing the paper application.
  • NPI email notification. These notifications are generated by the NPPES and are sent to suppliers who applied for the NPI through the web-based process.

Further, CMS has stated a copy of the NPPES screenshot, verifying the NPI, is acceptable for Medicare enrollment purposes. However, the screenshot must show the required information, be legible and unaltered in any way.

Again, suppliers must furnish the NPI in the proper section(s) of the CMS 855S and submit an acceptable form of notification from the NPPES before any enrollment documentation is processed.

Attached are some examples of acceptable NPI notifications. Please view the examples below.
