What Maryland Just Said: ePREP Is Being Replaced by MPRIME — and There's a Revalidation Trap

If you bill Maryland Medicaid — as a residential service agency, an assisted living program that takes the waiver, a home health agency, or any other provider — the portal you use to enroll and revalidate is changing. Maryland Medicaid is retiring ePREP and replacing it with a new system called MPRIME (the Maryland Provider Registration and Information Management Enterprise), going live in October 2026.

Most of this is a routine system swap. But buried in the transition is a timing trap that can get a provider suspended, and it’s worth understanding before it bites you.

Who this applies to

Every Maryland Medicaid provider. If you have an ePREP account today — RSA, ALF, home health, day services, DDA provider — you’ll be moving to MPRIME.

What’s actually changing

ePREP is Maryland Medicaid’s current online provider enrollment and revalidation portal. MPRIME replaces it. Same core job — how you enroll, revalidate, and manage your Medicaid provider information — new system. Before MPRIME goes live, Maryland Medicaid is putting an application hold in place (a period where new applications and changes pause during the switchover).

The dates that matter — and the trap

• MPRIME goes live: October 2026.
• The revalidation trap: if your revalidation was scheduled between July 1, 2026 and the October go-live, Maryland Medicaid moved it earlier so it wouldn’t collide with the application hold. They began issuing early revalidation notices on a rolling basis in February, with the final ones out by April.
• You get 90 days from your notice to complete that revalidation before the hold takes effect. Providers who don’t complete it within 90 days may be suspended.

Read that last line twice. If you had a revalidation due this summer or fall, your notice already came early — and if it’s sitting unhandled in an inbox, your 90-day clock may be running out. A suspended Medicaid enrollment means you stop getting paid. This is the part of the memo that actually has teeth.

What to do about it

1. Check whether you had a revalidation due between July 1 and October 2026. If yes, look for an early revalidation notice (issued February–April) and complete it now — don’t wait for the old due date, it moved up.
2. Register for MPRIME training. Maryland Medicaid is offering training sessions, and recorded tutorials, system-navigation guides, and provider checklists are already posted on the MPRIME site. Get your billing/enrollment staff through them before October.
3. Use the right inbox. All MPRIME questions go to [email protected] — but check the FAQ first; they’ll redirect you to it otherwise. Questions sent to random MDH staff may not be answered.
4. Watch for fall communications. More training and go-live guidance is coming over the next few months. Don’t let October be a surprise.

Why this is easy to miss

It’s a Medicaid enrollment change, not a licensing or training change — so it lands with your billing person, not your administrator, and the suspension risk is one sentence deep in a transmittal. The providers who get caught aren’t careless; they just filed it under “IT stuff, deal with it later.” Don’t.
