MPRIME vs ePREP: What Maryland Medicaid Providers Must Do

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 Information Management Enterprise), which went live on October 13, 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.

Update, October 13, 2026 (PT 36-27): MPRIME is live at mprime.health.maryland.gov. ePREP logins do not carry over, so every user creates a new account and then associates it with the provider. Two new rules came with the launch: providers without an SDAT identification number in good standing are suspended from Medicaid immediately and cannot submit applications, and facilities and organizations must upload their current license in MPRIME, approved, by March 31, 2027 or go into license suspension on April 1. Full details in the new section below.

Update, September 16, 2026 (PT 28-27): the dates are now firm. ePREP access ends October 1, 2026. It is already read-only. Anything you have not downloaded by 5:00 PM on Wednesday, September 30, 2026 is lost, and the transmittal states that Maryland Medicaid “will not retrieve any documentation for providers who fail to download it before the deadline.” MPRIME launches Tuesday, October 13, 2026. Nothing is required on launch day; the login link comes in a separate transmittal about a week before. Details in the dates section below.

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).

What changed on launch day (PT 36-27, October 8, 2026)

The launch transmittal arrived as a four-page PDF with no summary in the email. Here is what it actually asks of you.

Create a new user account, then associate it with your provider. Your ePREP login was not transferred. Each person who needs access goes to mprime.health.maryland.gov, creates a user account, and then associates that account with your existing provider profile. The first user to associate can grant themselves administrative privileges over the account. Until someone has done this, nobody can view or act on your Medicaid enrollment. The step-by-step is in the User Account Creation and Provider Association Guide on the MPRIME Resource and Training Center, along with a recorded demonstration. There is no deadline for this step, but every other action below happens inside MPRIME, so do it this month.

Your SDAT number now has teeth. Maryland Medicaid regulations require every provider to hold, and stay in good standing with, a State Department of Assessments and Taxation identification number that matches its organizational structure. As of October 13, 2026:

• Providers without an SDAT number in good standing cannot submit any application in MPRIME, and
• Providers without an SDAT number in good standing are immediately suspended from Maryland Medicaid.

MPRIME has an automatic interface with SDAT and will re-check your standing on an ongoing basis. Fall out of good standing (a missed annual report, a forfeited charter) and the suspension is automatic. Return to good standing and the suspension lifts automatically. If your enrollment simply has no SDAT number on file, you obtain one and submit an update application in MPRIME to add it. You can check your entity’s status for free on Maryland Business Express under the business entity search.

Upload your license in MPRIME by March 31, 2027. Every facility, organizational, and group enrollment that depends on a license or certification must now submit renewed license documents directly through MPRIME. The transmittal names home health agencies and waiver organizations, behavioral health organizations, nursing facilities, hospitals, labs, and group practices, and says the list is not exhaustive. To cover the application hold, Maryland Medicaid gave non-evergreen organizational licenses a temporary extension through March 31, 2027. Before that date you must log in, submit a supplemental update application with the renewed license attached showing the new expiration date, and have it finalized and approved. Providers whose license on file is still expired on April 1, 2027 go into license suspension (Status 54). Claims for dates of service during a suspension cannot be paid, and you may not bill the participant for them either.

Backdated enrollment for new providers. If you are enrolling a new provider or provider type, a complete and processable MPRIME application submitted by December 31, 2026 gets a backdated effective date: the later of your application-hold start (July 1 for high and moderate risk types, August 1 for limited risk) or your license issuance date. Miss December 31 and there is no backdate, with no exceptions. Do not bill for the backdated period until the application is approved.

Revalidation suspensions carry over. If you were suspended for missing the early revalidation window, you stay suspended in MPRIME until you file the revalidation application there. Unresolved for a year, the enrollment is terminated.

The dates that matter — and the trap

• Last day to pull your records from ePREP: Wednesday, September 30, 2026, 5:00 PM. ePREP is read-only now. Download your enrollment application, approval and revalidation letters, uploaded licenses and attachments, and correspondence before then.
• ePREP access ends: October 1, 2026. All providers lose access. Nothing left behind is recoverable.
• MPRIME goes live: Tuesday, October 13, 2026. You are not required to set up or associate your user account on launch day. Any date on or after October 13 works. The MPRIME link arrives by provider transmittal the week before launch.
• 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

Now that MPRIME is live, the list looks like this:

1. Create your MPRIME user account and associate your provider. Do it for the administrator and for whoever handles billing and enrollment. Grant admin rights to at least two people so one departure does not lock you out.
2. Confirm your SDAT standing today. Search your entity on Maryland Business Express. If it shows anything other than good standing, fix it with SDAT first, because Medicaid is already suspending on this.
3. Calendar March 31, 2027 for the license upload. Submit the supplemental update application with your renewed license well before then, since it has to be approved, not just submitted.
4. Check whether you were suspended for a missed revalidation. If yes, file the revalidation in MPRIME now; the one-year termination clock is running.
5. Use the right inbox. MPRIME access and license workflow questions go to [email protected] or the Provider Services Call Center at 1-844-463-7768. Check the FAQ on the Resource and Training Center first.

The original pre-launch checklist, kept for the record:

1. Download your ePREP file this week. Log in, save every document you might ever need to show a surveyor, an auditor, or a managed care organization, and store it where both your administrator and your billing person can find it. Deadline: September 30, 5:00 PM.
2. 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.
3. Catch up on MPRIME training. If you missed the live sessions, the recordings, guidance documents, and FAQ are on the MPRIME Resource and Training Center. Get your billing/enrollment staff through them before October 13.
4. 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.
5. Watch for the launch transmittal. The MPRIME link is coming by transmittal the week of October 6. Don’t let October 13 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.
