Update to “TMHP EDI Onboarding and Testing Changes Effective December 31, 2025”

Last updated on

This is an update to the article titled “TMHP EDI Onboarding and Testing Changes Effective December 31, 2025,” that was published on this website on December 9, 2025. The Texas Medicaid & Healthcare Partnership (TMHP) has changed the decommission date for the Electronic Data Interchange (EDI) testing site, also known as Ramp Management, from December 31, 2025, to January 31, 2026, at 11:59 p.m.

Beginning February 1, 2026, Edifecs, the web-based self-testing tool (editesting.tmhp.com), will no longer be supported. TMHP’s EDI onboarding and testing process will use the Regression Test Environment as the only testing platform for providers, trading partners, and software vendors that want to submit EDI transactions to TMHP.

Note: The TMHP EDI Connectivity Guide and Companion Guides will be updated to reflect these changes.
