What to Expect After Submission

Approved Pending Regional Office Review

For ASCs and PXRS:

  • When credentialing, you will receive an approved pending regional office review status in PECOS.  
  • National Government Services will send you a letter either by mail, email or faxed indicating your application has been sent to the State Agency and CMS regional office with important information about your enrollment process.
  • Once the notification is received from the state and/or CMS regional office, NGS will finalize the transaction and notify you of completion.

If you have questions on the status of the state or CMS regional office review or process, please contact the applicable agency.
