CHAMPS (Community Health Automated Medicaid Processing System) is Michigan Medicaid's provider portal, where enrollment, eligibility, claims, and prior authorizations are handled. Your biller needs access to it to do that work on your behalf.

Can I just share my CHAMPS login with my biller?

No. CHAMPS access runs through MiLogin, and each person is meant to have their own login — sharing credentials breaks your audit trail and can create security and HIPAA exposure. Instead, you add your biller as their own user and assign them a profile, which is the secure and compliant way to grant access.

Who is my Domain Administrator?

Whoever first submitted your Medicaid enrollment application in CHAMPS became your Domain Administrator by default. Only the Domain Administrator sees the Admin tab and can add users. If you're not sure who it is, or that person has left, see our guide on what to do if you lost access to CHAMPS.

What profile should I give my biller?

CHAMPS Full Access, if you want them to run your Medicaid billing end to end. It grants access to every tab except the Admin tab, so you keep control of user management. If you also want your biller to add and remove other users, add the Domain Administrator profile too — but keep at least one Domain Administrator in-house.

Does my biller need their own MiLogin account first?

Yes. Your biller registers their own MiLogin account and subscribes to CHAMPS, then gives you their User ID to enter on the Admin tab. You never need their password. If Bomi is your biller, we handle our side and simply send you the MiLogin User ID to add.

Can I remove my biller's access later?

Yes. As the Domain Administrator, you can set an expiration date on their user or remove their profile at any time from Admin → User List. No password change is needed, since each user has their own login.

Authorizing Your Biller for CHAMPS Access

By George Ruan • July 6, 2026

Rather than managing Michigan Medicaid yourself, Bomi can handle your billing and credentialing for you — so you can get back to seeing clients sooner.

CHAMPS — the Community Health Automated Medicaid Processing System — is Michigan Medicaid's provider portal. It's where your biller verifies member eligibility, submits and tracks claims, works prior authorizations, and manages your Medicaid enrollment.

CHAMPS is a provider-controlled system: whoever first enrolled your practice is its Domain Administrator, and only that person can grant access to other users. So instead of sharing your login, you add your biller as their own user and give them full access. It is a one-time setup that takes about five minutes.

How to Add Your Biller in CHAMPS

Step 1 — Sign in and choose the Domain Administrator profile.

Step 4 — Enter your biller's User ID.

Step 5 — Give them CHAMPS Full Access, then click OK.

In Available Profiles, select CHAMPS Full Access, click the arrow to move it into Selected Profiles, and click OK. CHAMPS Full Access lets your biller work every part of your Medicaid account — enrollment, eligibility, claims, and prior authorization. It covers every tab except the Admin tab, so control over who else gets access stays with you.

Which Profile Should You Pick?

CHAMPS Full Access — the one to choose for a biller who runs your Medicaid billing end to end. It grants full access to Provider Enrollment, Eligibility, Claims, and Prior Authorization, and covers every tab except the Admin tab — so you keep control of who else gets in.
Narrower profiles — if you would rather limit scope, CHAMPS also offers profiles like Claims Access (claims only), Eligibility Inquiry (eligibility only), and Prior Authorization Access (authorizations only). Most practices handing billing to one partner just use CHAMPS Full Access.
Domain Administrator — add this only if you also want your biller to add and remove other users. Keep at least one Domain Administrator in-house so you are never locked out of your own account.

Quick Summary

Sign in to CHAMPS and select the Domain Administrator profile for your practice.
Go to Admin → User List → Add.
Enter your biller's MiLogin User ID (for Bomi, the ID we send you).
Move CHAMPS Full Access into Selected Profiles and click OK.

Once you've added us, let us know and we'll confirm we can sign in. From there we handle the eligibility checks, claims, prior authorizations, and Medicaid enrollment through your CHAMPS account, and you can get back to your clients.
