Final Notification to Trading Partners about Taking Action Now Before MaineCare’s New Online Portal Goes Live
A refreshed and upgraded MIHMS is coming in mid October 2026. The Office of MaineCare Services (OMS), in partnership with Gainwell Technologies, is launching an upgraded MIHMS, to bring enhanced security, improved usability, and a more modern experience to better support your day-to-day work.
The upgrade will include a new “MaineCare Partner Portal” that will replace what is known today as the “Health PAS Online Portal.” Please note that, until the October go-live, we will continue using the name “Health PAS Online Portal” in communications related to current functionality.
You can read more about the benefits to providers and members on the Health PAS Online Portal.
Trading Partners Preparation
This is the final notice reminding trading partners to take action to prepare for the transition to the upgraded online portal, called the MaineCare Partner Portal.
Trading partners include providers, billing agents, health plans, clearinghouses, and business associates. Trading partners have an important role to play in supporting a smooth transition and uninterrupted access to the portal after go-live.
Portal Access Impacts and Required Actions Before Go‑Live
The preparation activities and changes below will improve system security by ensuring the right people have the right access, at go-live and ongoing. Most actions are only for Admin (R7) users.
Most important: Providers with duplicate emails need to make changes to their portal user accounts now to assist with account migration to the upgraded portal. On September 1, we will terminate current Admin (R7) user accounts that share an email address with another user account. We will not terminate Admin (R7) user accounts if they are the only Admin (R7) on the Trading Partner account.
If a user account is terminated and they still need portal access, another user with Admin Rights (R7) can invite the terminated user using a unique email address, not the one previously used.

Why it Matters |
What’s Next? |
|
At go-live, MaineCare will only migrate Admin (R7) accounts to the new portal.
MaineCare will not migrate inactive accounts. |
Designate at least one active Admin (R7) per organization, and two for backup coverage.
Trading Partners with large user populations should plan for sufficient Admin (R7) coverage to avoid access delays after go-live; we recommend one Admin (R7) per 25 users.
Remove inactive Admin (R7) accounts. |
After go-live, Admin (R7) users will need to re-invite all other active users. More Admin (R7) users mean less re-invitation work for each user.
Trading Partners have an existing and ongoing responsibility to remove inactive users to help keep our systems and data secure.
|
We will monitor the number and activity of Admin (R7) users per Trading Partner and will reach out to individual Trading Partners if needed. |
|
In the new portal, your username will be your email address. MaineCare will not migrate accounts that share an email address. |
Confirm that each active Admin (R7) user account has its own unique email address. OMS will deactivate accounts that continue to share email addresses as we approach go-live. |
After go-live, Admin (R7) users will need immediate access to the portal to invite other users and avoid disruption in Trading Partner work. |
We will monitor accounts that share email addresses and will reach out to individual Trading Partners if needed. |
|
Admin (R7) users will invite other users to the portal and designate your roles after go-live.
Admin (R7) will be able to choose from ~40 permissions, compared to 9 today. |
Prepare to invite users after go-live:
|
Admin (R7) users will need to invite other users shortly after go-live to avoid a disruption in Trading Partner work.
|
We will share more information during trainings including role definitions, templates, and other guidance. |
