Arkansas Medicaid Provider Enrollment Guide (MMIS & PASSE) – 2026

Back to All Resources

Guide Overview

If you are trying to complete Arkansas Medicaid provider enrollment, you typically need both central approval through the Arkansas Medicaid Provider Portal (MMIS) and, for many behavioral and I/DD providers, secondary network contracts with the state’s PASSE entities. This guide is written for office managers, credentialing coordinators, billing leads, and practice owners who need a practical Arkansas roadmap for portal setup, taxonomy verification, ownership disclosures, document prep, and PASSE contracting.

A common Arkansas mistake is assuming MMIS portal approval alone authorizes billing for PASSE members, when PASSE network contracts actually control whether those claims are payable. Similar to our Illinois and Idaho Medicaid guides, managing both state and network layers is essential to prevent denials and revenue gaps.

Who needs this Arkansas Medicaid guide?

Navigating the Arkansas Medicaid Provider Portal and PASSE requirements requires more than basic data entry. This guide is written specifically for:

• Medical and Behavioral Clinics: Practices seeking Fee-for-Service billing plus PASSE participation for high-acuity populations. Helpful details on organizational setups can be found in our behavioral health credentialing guide.
• Solo Practitioners & Group Practices: Providers who must align NPI taxonomy and ownership disclosures with MMIS rules. Helpful details on organizational files can be found in our group practice credentialing guide.
• Therapy, ABA, and I/DD Providers: Clinics that must understand PASSE contracting to avoid denials.
• DME Suppliers: Organizations affected by CMS moratorium cycles and heightened compliance scrutiny.

How Arkansas Medicaid enrollment is structured

Arkansas Medicaid enrollment is divided into two main layers for many providers: core MMIS enrollment and, for certain services, PASSE network contracting.

• Layer 1: MMIS Portal Enrollment (State-Level Approval): Secures your Arkansas Medicaid Provider ID and Fee-for-Service billing status via the Arkansas Medicaid Provider Portal, operated by Gainwell Technologies for the Division of Medical Services (DMS). Common failure point: taxonomy mismatches, incomplete CMS-1513 ownership disclosures, or missing supporting documents.
• Layer 2: PASSE Network Contracting: Provider-Led Arkansas Shared Savings Entities manage care for behavioral health and I/DD populations. Behavioral and therapy providers must contract with PASSE networks to bill for PASSE-enrolled members. Common failure point: assuming MMIS approval alone is sufficient for PASSE billing.

How to enroll in Arkansas Medicaid as a provider (summary)

For quick reference, here is the condensed overview of the Arkansas enrollment sequence:

1. Confirm that your Arkansas professional license and NPI taxonomy are active and aligned.
2. Create your account on the Arkansas Medicaid Provider Portal and assign a Primary Administrator.
3. Select the correct provider category and verify taxonomy codes against NPPES.
4. Complete CMS-1513 ownership and control disclosures for 5%+ owners and managing employees.
5. Upload required dossier documents (licenses, W-9, EIN confirmation, liability coverage, banking details).
6. Sign the Arkansas Medicaid Provider Agreement and track your Application Tracking Number (ATN) during MMIS review.
7. If you provide behavioral, therapy, or I/DD services, complete separate credentialing with Summit Community Care, Empower Healthcare Solutions, and CareSource PASSE after your MMIS Provider ID is issued.

Arkansas provider types and enrollment pathways

Arkansas Medicaid recognizes different provider classifications depending on billing structure and services:

• Group Practice (Type 2 NPI): For clinics and organizations billing under a Tax ID.
• Rendering / Individual Provider (Type 1 NPI): For clinicians linked to a group or billing under their own NPI.
• Behavioral / I/DD Providers: For practices serving PASSE-enrolled members who require network contracts in addition to MMIS enrollment.
• DME Suppliers and Other Specialized Types: For entities subject to additional compliance rules and occasional CMS moratoriums. Specialty examples of moderate/high-risk providers include DME suppliers, Home Health Agencies, and behavioral health programs.

The PASSE model – what makes Arkansas unique

Arkansas’s Provider-Led Arkansas Shared Savings Entity (PASSE) model integrates physical and behavioral health coordination for members with complex behavioral conditions and intellectual or developmental disabilities. PASSEs are provider-led risk-bearing organizations, not traditional commercial managed care plans.

MMIS portal enrollment alone does not authorize billing for PASSE-enrolled beneficiaries. Behavioral, psychiatric, therapy, ABA, and I/DD providers must execute separate contracts with each active PASSE network:

• Summit Community Care – partnered with Centene Corporation.
• Empower Healthcare Solutions – joint venture with local providers and Carelon Behavioral Health.
• CareSource PASSE – non-profit PASSE care coordination network.

If you treat PASSE members without these contracts in place, related claims will deny. For most behavioral and I/DD providers, PASSE contracting is as critical as MMIS enrollment.

Durable Medical Equipment (DME) and the CMS moratorium

Arkansas Medicaid enforces strict rules for Durable Medical Equipment (DME) suppliers. CMS periodically imposes temporary moratoriums on new DME enrollments in Arkansas to control fraud and over-utilization.

During an active moratorium:

• New DME supplier applications submitted through the portal are automatically rejected.
• Existing suppliers remain active but must maintain compliance audit readiness.
• Prospective DME providers must check the CMS moratorium registry before starting enrollment to avoid wasted effort.
