Virginia Medicaid Service Authorizations

Service authorization is one of the highest-risk Virginia Medicaid workflows for behavioral health providers. The right path depends on the member’s coverage lane, the service, the provider type, and whether the request belongs to fee-for-service, an MCO, or Acentra/Atrezzo.
Bottom line: Acentra Health handles many fee-for-service service authorization workflows through Atrezzo Next Generation. DMAS now points Atrezzo users to the standard MES login for FFS service authorization access. Cardinal Care MCO members may follow plan-specific authorization rules, so eligibility and plan assignment come first.

What Acentra and Atrezzo Do
DMAS’s service authorization page says Acentra Health accepts service authorization requests through Atrezzo Next Generation, telephone, paper, and fax submission, with direct data entry preferred for quicker response. The MES service authorization page currently tells Atrezzo users to log in using the standard MES login.
In practice, this means the authorization workflow is tied to both the clinical service and the portal access model. A biller may need PRSS access for provider records and remittance work, but service authorization can require a separate Acentra/Atrezzo workflow.
FFS vs MCO Authorization
Fee-for-service. Check DMAS manuals and Acentra/Atrezzo requirements for the service. The MES single sign-on bulletin and service authorization page are key source checks.
Cardinal Care MCO. Check the assigned plan’s authorization policy, portal, and provider relations instructions. The state service authorization contractor is not always the operational path for a managed-care member.
Behavioral health and ARTS. Use the current Mental Health Services, ARTS, psychiatric, residential, and telehealth manual sections that apply to the service being delivered.
Authorization Checklist
Verify eligibility and plan assignment for the service date.
Identify the exact service, CPT/HCPCS code, modifier, provider type, and provider specialty or taxonomy.
Check whether the service is fee-for-service or MCO-managed for this member.
Confirm whether the request belongs in Acentra/Atrezzo, an MCO portal, or another plan-specific workflow.
Keep authorization IDs, date ranges, units, service location, and approved service details with the claim record.
Why the 2026 MES Login Change Matters
DMAS published a bulletin on the new single sign-on requirement for FFS service authorization requests with Acentra ANG through MES. Operationally, that means old bookmarks and separate login assumptions can break. Start from the MES service authorization page and train the billing team on the current access path.
Action Steps for Providers
Add an authorization lane to your eligibility checklist: FFS/Acentra, MCO, or not required.
Review the current manual chapter for the service, not only a generic payer note.
Keep authorization evidence with the session and claim so denials can be appealed quickly.
