Georgia Medicaid Provider Portal: Login & Enrollment 2026

The Georgia Medicaid Provider Portal is called GAMMIS (Georgia Medicaid Management Information System). It is the main website for healthcare providers in Georgia.

Providers use GAMMIS to submit claims, check patient eligibility, and get paid by Medicaid.

How to Log In to GAMMIS (Step-by-Step)

Step 1: Go to the GAMMIS Website

Visit www.MMIS.georgia.gov

Save this page in your bookmarks. Use a desktop or laptop computer for best results.

Step 2: Find the Login Button

Look for “User Information” on the upper left side of the homepage. Click the Login button.

Step 3: Enter Your Credentials

Type in:

• Your User ID (username)
• Your Password
• Your 6-digit MFA code

The MFA code comes from an authenticator app on your phone. The code changes every 30 seconds.

Step 4: Access Your Account

After entering the correct information, you will see your secure provider dashboard.

First-time users: Wait at least 1 hour after receiving your registration email before logging in.

How to Set Up Your Account (New Providers)

When Do You Get Your PIN?

New providers receive a PIN letter 5–7 business days after enrollment approval. You need this PIN to create your GAMMIS account.

Steps to Activate Your Account

1. Go to the PIN Activation page on GAMMIS
2. Enter your Provider ID and PIN from your letter
3. Create a strong password
4. Set up Multi-Factor Authentication (MFA)
5. Complete the verification steps
6. Check your email for a confirmation message

Important: Wait 1 hour after getting the confirmation email before you log in. Check your spam folder if you do not see the email.

Multi-Factor Authentication (MFA) Explained

What Is MFA?

MFA adds extra security to your account. You need two things to log in:

1. Your password (something you know)
2. A code from your phone (something you have)

All GAMMIS accounts must use MFA.

Which Authenticator Apps Work?

You can use any app that supports TOTP (Time-Based One-Time Passcode), including:

• Google Authenticator
• Microsoft Authenticator
• Twilio Authy
• Duo Mobile
• Okta Verify

How to Set Up MFA

1. Log in to GAMMIS with your username and password
2. The system will show you a QR code
3. Open your authenticator app
4. Tap “Add Account” or the plus sign (+)
5. Scan the QR code with your phone camera
6. Enter the 6-digit code shown in the app
7. Your MFA is now active

No camera? You can type the secret code manually instead of scanning the QR code.

MFA Troubleshooting: Common Problems & Solutions

Problem 1: The 6-Digit Code Does Not Work

Solution: Check your phone’s time setting. The code only works if your phone shows the correct time.

Go to Settings → Date & Time → Set Automatically

Verify the correct time at https://www.time.gov/

Problem 2: Cannot Find GAMMIS in Authenticator App

Solution: Do not use your phone’s camera app directly.

Instead:

1. Open your authenticator app first
2. Tap “Add Account” or the plus sign (+)
3. Choose “Scan QR Code”
4. Allow camera access
5. Point your phone at the QR code on the screen

Problem 3: Blank Screen After Entering Code

Solution: The code you entered is incorrect. Authenticator codes change every 30 seconds.

Wait for the next code to appear. Try again with the new code.

If it still fails:

• Write down the current code
• Wait 30 seconds
• Try the code you wrote down

Problem 4: Error After Multiple Wrong Codes

Solution: You entered the wrong code too many times. The system locked you out.

To reset:

1. Close all browser windows completely
2. Wait 2–3 minutes
3. Open a new browser window
4. Check your phone’s time setting
5. Make sure you are looking at the correct GAMMIS account in your authenticator app
6. Try logging in again

Problem 5: Lost Phone or Need to Reset MFA

Solution: Call the Gainwell Technologies Helpdesk at (800) 766-4456

They will reset your MFA. When you log in next, you will get a new QR code to scan.

You still need to know your password.

Problem 6: Forgot Password

Solution: On the GAMMIS login page:

1. Click “Having Trouble Logging In?”
2. Enter your User ID
3. Enter your email address
4. Check your email for a password reset link
5. Click the link
6. Answer your security question
7. Create a new password

Note: This only works if you changed your password in the last 180 days. If not, call the helpdesk at (800) 766-4456.

URGENT: Group/Billing Provider Enrollment Deadline

What Is the New Requirement?

Starting July 1, 2025, Georgia Medicaid requires all provider groups to complete a new enrollment process.

This applies even if you already have a payee ID or existing enrollment.

Why Is This Important?

Deadline: January 1, 2026

If you do not complete group enrollment by this date, your claims will be denied starting January 1, 2026.

Who Must Enroll?

You must complete group enrollment if:

• You submit professional claims under a group NPI
• Your rendering provider NPI is different from your billing provider NPI
• You are a clinic or group practice
• You already have a payee ID (you still need to enroll as a group)

Exception: DBHDD Facility Providers and FQHC Providers do NOT need to complete group enrollment.

How to Complete Group Enrollment

1. Log in to GAMMIS at www.MMIS.georgia.gov
2. Click Provider Enrollment → Provider Enrollment Application
3. Choose “Group/Billing” as your enrollment type
4. Fill out the group information form:
   • Group demographic details
   • Business ownership information
   • Group NPI (must be valid and registered)
   • Payee Medicaid ID (if you have one)
5. Under Affiliations, add at least 2 individual rendering provider Medicaid IDs
6. Upload required documents:
   • Current Business License
   • Georgia Secretary of State Certificate of Existence
7. Submit the application
8. You will receive an Automated Tracking Number (ATN)
9. Check your GAMMIS portal regularly to track your application status

How Long Does Approval Take?

Most applications are approved within 2 weeks of submission. However, incomplete applications take much longer.

Do not wait until the last minute. Submit your application as soon as possible.
