Maryland Medicaid ABA group and individual enrollment through the ePREP to MPRIME transition requires a transition-ready evidence file. As of September 1, 2026, Maryland says provider-enrollment applications are on hold while the state moves to MPRIME for an October launch. ABA organizations should preserve separate group and individual identities, former ePREP records and current notices, without treating temporary Carelon registration or possible backdating as approval or a payment guarantee.

Name the Maryland record before planning a submission

Maryland's current ABA manual separates the group from the professionals who render or supervise services. The group file should contain the legal organization, tax identity, Type 2 NPI, ownership, service and records locations, pay-to data and authorized representatives. Every licensed psychologist, BCBA-D, BCBA, BCaBA, RBT or behavior technician should have a distinct professional or rendering file supported by the role's current requirements. Maryland ABA provider classifications

The state enrollment record and the behavioral-health administrative-services organization record are also different. Maryland states that its provider-enrollment portal is managed by the Department, not by the ASO. A Carelon record therefore does not replace state enrollment. The evidence map should identify which authority produced every identifier, status and date.

Maryland's ABA individual addendum uses provider type AB for the individual enrollment category and role-specific information. Maryland provider addenda An internal shorthand such as “ABA enrolled” can hide whether the note refers to a group, an individual, a rendering relationship or an ASO registration.

Qualified professional and legal owners must verify licensure, certification, scope, supervision and ownership. Administrative staff may organize the application data and identify inconsistencies without selecting a professional role or attesting to facts they did not establish.

Work from the active MPRIME hold, not a retired screen path

Maryland's MPRIME page says all provider application holds are active as of August 1, 2026 and the new system is scheduled to go live in October. Current MPRIME status The general Maryland provider enrollment page now points providers to the transition rather than offering the retired application path. On September 1, a new guide should not instruct the reader to submit an ePREP application as if the former path were open.

Create a transition inventory for every application or planned record. Label the provider identity, former ePREP status or identifier, hold start, missing information, intended MPRIME action, responsible owner and current state communication. Do not convert an unfinished or held application into an approved record in an internal tracker.

The transition FAQ explains the state's retirement of ePREP and movement to MPRIME. Provider enrollment portal transition FAQ Practices should retain ePREP confirmations, correspondence and approved history that may be needed to reconcile data after launch. Historical evidence should not be overwritten by a new system identifier.

Maryland has also published MPRIME training information. MPRIME training sessions Named users should attend or review the current materials for their actual role. Training attendance is useful preparation, but it does not establish a submitted or approved application.

Build the group file around the legal and operating entity

The group record should reconcile legal name, Type 2 NPI, tax information, ownership and controlling interests, pay-to data, service and records locations, authorized users and the rendering professionals expected to affiliate. Each field should point to the official evidence and its checked date.

An organization should decide who may make ownership, disclosure and legal attestations before the new application is entered. Operations can prepare a field-to-evidence index, but the authorized owner must verify the representations. Shared credentials and untraceable signatures weaken the transition record.

Group approval does not establish every individual. Build a roster that distinguishes planned, submitted, held, approved, affiliated, ended and ASO-loaded statuses. An employment date, credentialing committee date or temporary registration should not be used as the Maryland Medicaid effective date.

Locations require deliberate mapping. A mailing address, service site, records location and pay-to address can be different. Preserve the prior approved location, the requested change and the written result so earlier dates of service can be understood after MPRIME launches.

Prepare every individual role on its own evidence

The current ABA manual lists the professional and paraprofessional identities relevant to the benefit, including licensed psychologists, BCBA-Ds, BCBAs, BCaBAs, RBTs and behavior technicians. ABA enrollment and qualification requirements Each person should have a legal name, Type 1 NPI, applicable Maryland license or certification, taxonomy, disclosures, supervisor and intended group relationship.

The behavior-technician pathway deserves particular care. The manual identifies specialty code 325 and describes a 90-day path for meeting the applicable qualification requirements. Preserve the hire or role date, training evidence, supervisor verification and the actual state or ASO result. Do not turn a general 90-day statement into an automatic approval or extend it without authority.

Maryland requirements can include criminal-history or background steps. Store the official completion or result with restricted access and avoid copying sensitive detail into a general operations sheet. Legal and professional owners should handle adverse or disputed information.

Licensure, board certification, NPI enumeration, state enrollment, group affiliation and ASO setup are separate facts. A green status in one source does not prove the others. The transition checklist should show every fact, source, checked date and responsible owner.

Read the transition backdating policy narrowly

Maryland's June 2026 update says a complete, processable MPRIME application submitted by December 31, 2026 may qualify for an effective date tied to the later of the application-hold start or license issuance, but backdating is not assured. MPRIME June transition update This is conditional relief, not blanket permission to bill before approval.

The same guidance says providers cannot bill or be paid before the enrollment application is approved. Hold claims that depend on a pending identity and preserve the service, eligibility, authorization and documentation evidence. Do not change a service date or provider relationship to anticipate a later effective result.

An emergency exception is limited to circumstances in which the hold would affect health, safety or wellbeing. The practice should retain the state's exact exception request, supporting facts, submitter and written response. A cash-flow concern alone should not be relabeled as the state's emergency standard.

For address changes and other transition questions, follow the current state instruction rather than assuming the former portal workflow remains available. Keep the submitted request and state response with the provider record so the resulting effective date can be reconciled later.

Use temporary Carelon registration only for its stated purpose

Maryland's August 21, 2026 notice describes a temporary courtesy-registration process with Carelon for certain provider NPIs affected by the MPRIME hold. Temporary Carelon registration instructions The notice expressly says the process does not guarantee payment and does not replace state enrollment.

The temporary route applies to specified groups, facilities, individual billers and sole proprietors who are unable to enroll during the hold and who attest that the temporary registration information is complete. It is not intended for rendering-only individuals or rendering providers joining an already-enrolled group. The practice should confirm the category before sending a request.

Already enrolled providers continue to use the existing Carelon process. A new temporary record should therefore not overwrite a valid ASO or state identifier. Track the NPI, requestor, attestation, temporary result, related MPRIME application and claims being held.

Care authorization, state enrollment and claim payment remain distinct. Qualified clinicians own assessment, treatment planning, medical necessity and documentation. Operations may coordinate an authorization or temporary registration, but should not invent clinical facts, codes or units and should not release held claims before the required enrollment result.

Reconcile MPRIME, verification and maintenance after launch

When MPRIME becomes available, compare every migrated or newly created record with the evidence inventory. Confirm the legal and professional identity, NPI, provider type, specialty, group relationship, locations, disclosures and effective date. Preserve any discrepancy and state correction rather than silently changing the internal history.

Maryland provides a provider-verification route for checking enrollment status. Maryland Provider Verification System A verification result supports the status shown on the checked date; it does not by itself prove the full application evidence, Carelon participation, authorization or payment for a particular claim.

Maintain a calendar for professional credentials, certifications, ownership, addresses, group relationships, banking, revalidation and state notices. The live MPRIME task and written communication should control the deadline. Keep former ePREP, temporary Carelon and MPRIME evidence linked by provider identity and date.

Imagine a fictional Maryland ABA group with a held application and one new BCBA. Its Maryland Medicaid ABA group and individual enrollment through the ePREP to MPRIME transition file documents both identities and the hold, uses temporary Carelon registration only if the published category fits, holds affected claims and completes MPRIME after launch. It does not represent the courtesy record or possible backdating as approval.

Finni describes administrative support on its provider services page. A Maryland engagement could be bounded to transition inventories, evidence organization, MPRIME coordination, Carelon handoffs, held-claim queues and maintenance. Maryland agencies, professional boards, Carelon, clinicians, payers and legal owners retain their decisions, and no administrator can guarantee enrollment, authorization, effective dating or payment.
