Reminder: TMHP EDI Connectivity Change Scheduled for August 2026

Last updated on

This is an update to the article titled, “Trading Partner Testing for Updated EDI Transaction Process to Begin May 1.”

Trading Partner Testing

Mandatory trading partner testing will be available through July 31, 2026. During this time, batch submitters must verify successful connectivity and migrate to the new Secure File Transfer Protocol (SFTP) method.

If testing and migration to the production SFTP platform has not been completed by July 31:

  • Batch submitters will lose their access to submit and retrieve Electronic Data Interchange (EDI) transactions through the virtual private network (VPN) connectivity method.
  • Interruptions in exchanging EDI X12 claims, eligibility, claims status inquiry, electronic remittance advice, and any other EDI batch transactions may occur.

Note: This update will only apply to batch submitters. Real-time submitters will not be affected.

All VPN connectivity for batch submitters will be disabled on August 1, 2026. For questions about trader partner testing, submitters can contact ediconnectivitysupport@tmhp.com.

Webinar

For more information and details, see the New Electronic Data Interchange Batch Submission Webinar available on the Texas Medicaid & Healthcare Partnership (TMHP) YouTube channel.
