TMHP EDI Onboarding and Testing Changes Effective December 31, 2025

Last updated on

On December 31, 2025, the Electronic Data Interchange (EDI) testing site, also known as Ramp Management, will be decommissioned. Edifecs, the web-based self-testing tool, will no longer be available for the Texas Medicaid & Healthcare Partnership’s (TMHP’s) EDI onboarding and testing process.

TMHP’s Regression Test Environment will serve as the only testing platform for providers, trading partners, and software vendors that want to submit EDI transactions to TMHP.

Note: The TMHP Connectivity Guide and Companion Guides will be updated to reflect the changes by December 31, 2025.
