Georgia Medicaid Eligibility Verification for Behavioral Health

Georgia Medicaid eligibility checks are about to matter more than usual. The state awarded new Georgia Families contracts, so the care management organization on a member's record may not be the one they had last year. For behavioral health, the check also has to separate CMO members from fee-for-service members whose community behavioral health runs through a different system.

Short answer

Verify Georgia Medicaid eligibility in GAMMIS, the Georgia Medicaid Management Information System, through its secure web portal, or through the Provider Services Contact Center and interactive voice response line at 1-800-766-4456. For behavioral health, confirm whether the member is in a Georgia Families care management organization or fee-for-service, and which CMO, because routing, authorization, and networks differ. Read the plan from GAMMIS at every visit during the CMO transition.

The Georgia Families transition

Georgia issued a notice of intent to award new Georgia Families contracts to CareSource, Humana, Molina, and UnitedHealthcare, with UnitedHealthcare also awarded Georgia Families 360, which covers children in foster care. The prior lineup included Amerigroup and Peach State Health Plan alongside CareSource. Members move between plans during a transition like this. Confirm effective dates with the Department of Community Health, and read the member's CMO from GAMMIS at each visit rather than from their card or your records. See Georgia Families news.

What the check has to answer

  • CMO or fee-for-service. Georgia Families members are managed by a CMO; others are fee-for-service, where community behavioral health is organized differently.
  • Which CMO. Each has its own network, prior authorization matrix, and portal.
  • Category of service and enrollment. Whether your GAMMIS enrollment and category of service support the service you plan to bill.
  • Pathways coverage. For Georgia Pathways members, coverage depends on meeting qualifying activity requirements, so verify each visit.

What eligibility will not tell you

Whether your clinician is in network with the member's CMO, and whether the service needs authorization. Both are plan-specific and change with the transition.

Verify at booking, then before each visit

Eligibility can change between booking and the visit, so check both times. Stable's AI receptionist verifies insurance during the booking call or text and books the patient with a clinician credentialed with their plan.
