Kentucky operates one of the most competitive Medicaid managed care markets in the nation with five MCOs, including the locally operated Passport Health Plan that serves only the Louisville region — creating a geographic credentialing complexity most out-of-state providers overlook.
What Is the KY MMIS Portal?
The Kentucky Medicaid Management Information System (KY MMIS) is the centralized portal for all provider enrollment, claims processing, and program management. All initial enrollments, revalidations, and demographic updates flow through KY MMIS.
Step-by-Step Kentucky Medicaid Enrollment
Kentucky enrollment requires KY MMIS registration followed by credentialing with up to five MCOs depending on your service area.
Register on the KY MMIS Portal
Create an account with your NPI, Tax ID, and Kentucky practice information. Select your provider type from Kentucky-specific classifications.
Complete Application
Enter demographics, Kentucky license, specialties, practice locations, ownership disclosures, and billing configuration.
Upload Documents
Upload KY license, NPI, W-9, EIN, liability insurance, DEA (if prescribing), voided check, and ownership disclosures.
Complete Screening
Kentucky conducts OIG/SAM checks, state licensing verification, KSP background checks for high-risk categories, and site visits for facilities.
Submit and Await Approval
Sign the provider agreement. Processing: 30–45 days.
Credential with MCOs
After KY MMIS approval, credential with Kentucky’s five MCOs. Louisville-area providers must include Passport Health Plan.
Kentucky’s Five-MCO Landscape
Kentucky has one of the most competitive MCO markets with five plans, including the unique locally-operated Passport Health Plan that only serves the Louisville region.
| MCO | Parent | Coverage |
|---|---|---|
| Anthem Kentucky | Elevance Health | Statewide; largest market share |
| Humana CareSource | Humana/CareSource JV | Statewide; strong in eastern KY |
| WellCare of Kentucky | Centene | Statewide |
| Aetna Better Health of KY | CVS Health | Statewide |
| Passport Health Plan | Local (University of Louisville) | Louisville region only |
⚠ Louisville Trap: Passport Health Plan is a locally operated MCO that only serves the Louisville/Jefferson County region. Out-of-state providers expanding into Louisville who skip Passport will miss a significant portion of that region’s Medicaid population. Conversely, providers outside Louisville do not need Passport credentialing.
✔ Strategy: Credential with Anthem and WellCare first (broadest statewide coverage), then Humana and Aetna. Add Passport only if serving the Louisville metro area.
