Georgia Medicaid enrollment at a glance
To bill Georgia Medicaid, enroll through Georgia Medicaid Management Information System (GAMMIS) — Enrollment Wizard, run by Gainwell Technologies. The process has 5 steps, listed below with the documents the state asks for.
- Program
- Georgia Medicaid and PeachCare for Kids (Department of Community Health)
- Fiscal agent
- Gainwell Technologies (GAMMIS fiscal agent / third-party administrator; also handles CVO credentialing help)
- Application fee
- Georgia's Part I manual requires the fee from new, re-enrolling, revalidating and re-credentialing providers in the categories of service it lists, unless exempt, or a hardship waiver request instead. Applications without either are not processed, the fee is generally non-refundable, and an exempt provider pays once per service location even with several categories of service. Federal rule (42 CFR 455.460): the state must collect the CMS application fee from institutional providers that are newly enrolling or re-enrolling; individual physicians and non-physician practitioners are exempt, as are providers already enrolled in (or that already paid the fee to) Medicare or another state's Medicaid/CHIP. CMS set the fee at $750 for calendar year 2026.
- Fingerprinting
- Georgia's high categorical risk categories are community mental health centers, newly enrolling home health agencies, and newly enrolling DME/orthotic and prosthetic supplier facilities. Georgia defines a criminal background check as a state and/or national fingerprint-based check. Federal rule (42 CFR 455.434, 455.450(c)): providers the state places in the 'high' categorical risk level, and anyone owning 5% or more of such a provider, must submit fingerprints for a criminal background check.
- Site visit
- DCH may do pre- and post-enrollment, unscheduled and unannounced site visits. Moderate-risk categories include ambulance providers, hospices, independent clinical labs, physical therapists, and revalidating home health agencies and DME suppliers. Federal rule (42 CFR 455.432, 455.450(b)-(c)): the state must do site visits before and after enrollment for providers in the 'moderate' or 'high' risk levels, and any enrolled provider must allow unannounced on-site inspections.
- Revalidation
- DCH suspended providers that had not revalidated as of July 1, 2026; claims for dates of service from then on are not paid until the provider revalidates, and the new effective date is the revalidation submission date. Federal rule (42 CFR 455.414): every enrolled provider must be revalidated at least once every 5 years.

Documents the state asks for
Joining managed-care plan networks
- Credentialing
- Yes — centralized. DCH runs an NCQA-certified Centralized Credentialing Verification Organization (CVO) through GAMMIS. Providers file one credentialing/recredentialing application that serves all Georgia Families and Georgia Families 360 CMOs, and complete applications get a decision within 45 calendar days. Providers still contract with each CMO separately. CMOs keep delegated credentialing for IPAs and PHOs. Centralized credentialing: yes.
