What to Expect After Submission

Requests for Additional Information

While processing the application(s), National Government Services may determine additional information is needed.

All requested information should be submitted as soon as possible, but no later than 30 days from the initial development letter date or claims payment will be impacted. 

  • The contact person (identified on application) will either receive an email, fax or USPS mail that will include the instructions for needed actions, corrections and required documents. The email will display from the sender customerservice-donotreply@cms.hhs.gov.
  • The application will be returned for corrections in PECOS. You must log into PECOS and access your application using the designated tracking ID and make the needed updates and/or corrections. Once the corrections have been made, resubmit the application back to the contractor, verify and manage the signature(s) as needed.

The contact person should be on the lookout for emails, routinely verify spam or junk email folders and add the customerservice-donotreply@cms.hhs.gov and NGS-PE-Communications@elevancehealth.com addresses to their safe senders list.
