The main Georgia Medicaid provider phone number is 1-800-766-4456, a toll-free line operated by Gainwell Technologies for the Georgia Department of Community Health. Use it for claim status, billing questions, prior authorization, enrollment, and general policy guidance. Several other lines handle narrower issues, and if your patient is enrolled in a Georgia Families managed care plan, you’ll often need to call that plan directly instead.

- Peach State Health Plan: 1-866-874-0633

What to Have Ready Before You Call
Gainwell representatives verify your identity before discussing claims or patient information, so pull these together before you dial:
- Georgia Medicaid Provider Number. GAMMIS assigns a 12-digit number to each provider. Numbers issued before November 1, 2010 begin with “111”; numbers issued afterward begin with “222.”
- National Provider Identifier (NPI). Your 10-digit federal provider ID.
- Tax Identification Number (TIN). The EIN or SSN tied to your billing entity.
- Member ID and date of service. Required for any question about a specific patient.
- Internal Control Number (ICN). The unique tracking number assigned to each submitted claim, found on the GAMMIS claims status tab or on your remittance advice.
Identity verification exists because HIPAA requires covered entities to confirm the identity and authority of anyone requesting protected health information. Without your credentials in hand, the representative may not be able to help you at all.
Navigating the Phone Menu
When you call 1-800-766-4456, the Interactive Voice Response system prompts you to enter your provider identification numbers on the keypad. From there the menu branches into eligibility verification, claim status, prior authorization, and enrollment. Entering an ICN in the claim status branch will pull up an automated update without a live agent.
To reach a person, follow the prompts for general inquiries or hold through the automated options. Call volume tends to peak from mid-morning through early afternoon, so calling right at 8:00 AM or after 3:00 PM usually shortens the wait. The agent will run a final identity check before opening your account, so keep your provider numbers and TIN within reach throughout the call.
When the GAMMIS Portal Is Faster Than the Phone
For routine tasks, the GAMMIS web portal at home.gammis.com is quicker than a phone call. Enrolled providers log in with a Provider ID and PIN to check claim status, view remittance information, and confirm member eligibility.3Georgia Medicaid Management Information System. Georgia MMIS The public-access section holds provider manuals, fee schedules, forms, and training materials.
New providers can start the enrollment process through the portal’s Enrollment Wizard, which covers both fee-for-service Medicaid and CMO enrollment in a single application.4Georgia Medicaid. Enrollment Application Office administrators needing portal access for existing providers can register at home.gammis.com/public/register. If you hit a technical problem logging in or registering, that’s when to call EDI Services at 1-877-261-8785 rather than the main provider services line.5Georgia Medicaid.
