Upgrades to HPI platforms and impact on website access

Health Plans Inc

We are pleased to share that Health Plans, Inc. (HPI), a third-party administrator of self-funded plans and a Harvard Pilgrim company, has upgraded some of its provider, member, and client-facing platforms — including the electronic tools and functionality on the convenient HPI provider portal.

As HPI continues to provide transformational and proactive solutions to customers, the elevated, user-friendly platforms will allow for more flexibility and process efficiencies while improving overall functionality. This includes the availability of a new provider tool known as MESA, which will be phasing out WEBeci and offering providers the ability to view member information such as claims, eligibility, and accumulations.

To ensure that you are channeled to the correct platform for your patient:

  1. Always start your online navigation for HPI membership at
  2. Once there, click “Provider Portal Start Page – Claims & Eligibility.”
  3. Please do not save the login page URLs (WEBeci or MESA) to your favorites, as they might not be the right platform for a given patient and could possibly display erroneous information.

Transition to MESA occurring through a phased approach

It’s important to note that during the phased process, HPI’s provider portal start page will guide providers to the new MESA platform for certain HPI members and to the original platform, WEBeci, for others, depending on the member’s employer group. WEBeci will remain in use until all member groups transition to the new system.
