Changes to the Written General Inquiries Process at National Government Services, Inc.

Effective 5/27/2025, NGS will no longer accept inquiries submitted through the postal service to any of our P.O. Boxes or faxed to any of our fax lines. The Medicare Correspondence Request Form will also no longer be accepted.

To submit general inquiries, you’ll need to use our free, secure internet portal, NGSConnex. If you’re not enrolled in NGSConnex, use the instructions in the Registration section of the applicable NGSConnex User Guide below to start the enrollment process:

• NGSConnex User Guide for Part A, HHH and FQHC providers
• NGSConnex User Guide for Part B providers

We offer webinars on a recurring basis that will provide an overview of NGSConnex, including how to register, navigate and submit inquiries. Visit our Events page to register.
