HPI Core System Update
Important: Use the “Provider Portal Start Page” link below to access your patient’s eligibility information and delete any existing bookmarked URLs.
HPI is undergoing a core system enhancement to upgrade our eligibility portal from WEBeci to MESA. Our employer groups are being moved to the upgraded system in batches, with all plans operating on the enhanced platform by July 1, 2025. When you enter your patient information into the Provider Portal Start Page form, you will be routed to the appropriate eligibility portal based on the patient’s plan. You may request credentials for MESA on the login page if you do not already have them. For more information about MESA and instructions for registering, please view the Provider Portal Instructions – MESA video linked below.
