The portal is portal.mmis.arkansas.gov. Arkansas Medicaid and ARKids First dental is fee-for-service, administered by Gainwell, with no dental benefit manager.
Dental managed care ended on 1 November 2024
Arkansas ran dental through managed care and stopped. Since 1 November 2024 the benefit has been fee-for-service again.
That matters if your written procedures, your practice management system notes, or the colleague who trained your front desk predate the change. Chasing a benefit manager that no longer holds the contract is the single most reliable way to lose an afternoon on an Arkansas claim, and the failure looks like a coverage problem rather than a routing one.
Two addresses that will waste your time
medicaid.state.ar.us has no DNS record. We checked on 10 September 2026 and it returns nothing — so an old bookmark fails with a browser error rather than redirecting anywhere useful.
armedicaid.com is a different problem. It resolves, so it does not fail. It is a parked domain offered for sale — not an Arkansas Medicaid service, and never was one you should be typing credentials into. A biller guessing the obvious short name lands there.

What to do
- Bookmark portal.mmis.arkansas.gov and reach it from the bookmark.
- Delete
medicaid.state.ar.usandarmedicaid.comfrom any written procedure. - Record that Arkansas dental has been fee-for-service since 1 November 2024, so nobody re-derives it.
- If an Arkansas claim denies oddly, check you are not still routing it to a benefit manager that lost the contract two years ago.
