Trading Partner Testing for Updated EDI Transaction Process to Begin May 1

Last updated on

This is an update to the article titled, “Update for TMHP EDI Transactions Process Scheduled for August 2026.”

The start date for trading partner testing has changed from April 1, 2026, to May 1, 2026.

The update to the electronic submission process for Electronic Data Interchange (EDI) transactions is still scheduled for August 2026. As part of this transition, a new connectivity method will be introduced that will affect batch submitters who currently connect using a virtual private network (VPN). The new supported EDI connectivity method will be Secure File Transfer Protocol (SFTP).

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

Trading Partner Testing

Important: All batch submitters must complete trading partner testing.

Trading partner testing will be available through July 31, 2026. During this time, batch submitters must verify successful connectivity and migrate to the new SFTP method.

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.

Updated EDI Guide

The Texas Medicaid & Healthcare Partnership (TMHP) has revised the EDI Connectivity Guide on to reflect this EDI update. Check tmhp.com regularly for further updates.
