To see Georgia Medicaid members, whether through traditional Medicaid or one of the state’s managed care plans, a clinician first has to be enrolled with Georgia Medicaid. Georgia is unusual in one useful way: managed care credentialing is centralized, so one verified application serves all of the plans. Here is how Georgia Medicaid provider enrollment works, step by step, as of 2026.

Who Runs Medicaid Enrollment in Georgia
Georgia Medicaid is administered by the Georgia Department of Community Health (DCH). Enrollment and claims run through GAMMIS, the Georgia Medicaid Management Information System, which is operated by DCH’s fiscal agent, Gainwell Technologies. Applications are submitted through the GAMMIS web portal at mmis.georgia.gov, under Provider Enrollment.
Before You Start
- An individual NPI, and a group NPI if you bill as a group.
- A current Georgia license.
- A W-9, because the practice name on the application must match it exactly. Some applicants are also asked for an IRS 147C letter confirming the tax ID.
- Complete ownership and managing-employee information.
- Hospital admitting privileges, if you have them.
How to Enroll, Step by Step
- Open the Enrollment Wizard in the GAMMIS portal and start a new provider enrollment application.
- Choose the request type. Options include standard enrollment, enrollment for managed care plans only, and enrollment for providers who only order, prescribe, or refer (OPR).
- Complete the application panels in order: provider contracts, specialty, provider details, and addresses.
- Write down your Application Tracking Number (ATN), which GAMMIS issues partway through and which you use to track status.
- Finish the remaining panels, including other state Medicaid enrollments, languages, admitting privileges, licenses, and the disclosure of ownership.
- Upload every document marked as required, then submit and track the application by ATN.
Ownership Disclosure and Site Visits
Georgia will not enroll a provider without a complete disclosure of ownership and managing employees. Certain facility types also require a site visit before enrollment. Under federal rules, providers in high-risk categories must also complete fingerprint-based criminal background checks.
Is There an Application Fee?
Individual physicians and non-physician practitioners are not charged an application fee. Institutional providers pay the federal application fee per service location, which is $750 for calendar year 2026, unless they have already paid it to Medicare or another state’s Medicaid program. Hardship waivers are available through CMS.
Managed Care: Enrollment First, Then Centralized Credentialing
Georgia’s managed care plans, called Care Management Organizations (CMOs), require clinicians to be active Georgia Medicaid providers, or to complete the Georgia Medicaid enrollment application, before they can be credentialed. Credentialing for all of the CMOs is centralized through a single NCQA-certified credentials verification organization built into GAMMIS, so you are not repeating the same verification for each plan. You still need a contract with each plan you join.
The current CMOs are Amerigroup, CareSource, and Peach State Health Plan, and their contracts have been extended through June 30, 2027. A new procurement, which in 2024 named CareSource, Humana, and Molina for Georgia Families and UnitedHealthcare for Georgia Families 360°, was still under protest as of April 2026, so the plan lineup may change.
Behavioral Health Clinicians
Since January 1, 2022, LPCs, LCSWs, and LMFTs can enroll in fee-for-service Medicaid under Psychological and Therapy Services, but that fee-for-service coverage is limited to members under 21. Clinicians who only see adult members through the CMOs can use the managed-care-only enrollment. Behavioral health agencies have an extra step: they must also be approved by and contracted with the Georgia Department of Behavioral Health and Developmental Disabilities (DBHDD). See our Georgia behavioral health billing page for the billing side.
Ordering, Prescribing, and Referring Providers
Georgia has required ordering, prescribing, and referring providers to be enrolled since April 2013, and their NPI is required on CMO claims as well. Georgia allows retroactive OPR enrollment when the application is filed within 60 days of the date of service.
Group Enrollment
Georgia has introduced a separate group (billing) enrollment, and a group must have at least two affiliated individual providers. If you bill under a group, confirm with DCH or your plans that both the group and each clinician are enrolled and linked correctly.
Revalidation
Georgia requires revalidation at least every five years, and it enforces the deadline. Providers who had not revalidated were suspended effective July 1, 2026; claims for dates of service on or after suspension are not paid, and suspended providers have 30 days before termination. Watch for revalidation notices and respond well before the deadline.
How Long It Takes
DCH states that the centralized credentials verification organization makes a decision within 45 calendar days of receiving a complete application. Older DCH guidance put a complete individual enrollment at roughly 15 business days and full plan credentialing at up to 120 days, so plan for several months from application to seeing CMO members.
Common Reasons Applications Stall
- A practice name that does not match the W-9 exactly.
- An incomplete ownership disclosure.
- Required documents missing from the upload step.
- Choosing fee-for-service enrollment for adult behavioral health services that are only covered through the CMOs.
