Louisiana Medicaid dental runs through two dental benefit plan managers, DentaQuest and MCNA Dental. Each member is served by one, so billing starts with knowing which. Children have comprehensive EPSDT dental; adult coverage is limited, with a 2026 medical-necessity expansion under Act 629. Here is how enrollment, claims, and denials work.

Each Medicaid member is served by one of them, so the first billing step is always knowing which plan manager a patient has. Children through age 20 have comprehensive EPSDT dental; adult coverage is limited to dentures and extractions unless the member qualifies for a waiver plan, and under Act 629 (effective August 1, 2026) Medicaid also covers dental that is medically necessary to clear a patient for another covered medical procedure.
Louisiana uses two dental benefit plan managers. Since January 1, 2021, the Louisiana Department of Health (LDH) has contracted with DentaQuest and MCNA Dental to manage Medicaid dental benefits. Each enrolled member is served by one of the two, so a Louisiana practice is effectively billing two separate plans with their own portals, networks, and rules.
This is a smaller version of the three-MCO model in a state like Texas: not one administrator, but not a dozen either. The practical consequence is the same, you cannot treat every Louisiana Medicaid patient identically, because the plan manager determines where eligibility, pre-authorization, and the claim go.
DentaQuest (1-800-685-0143) and MCNA Dental (1-855-702-6262, mcnala.net) each run their own provider network and portal for Louisiana Medicaid. A patient is assigned to or enrolled with one of them.
Verify the plan manager before the visit. Confirm which of the two a member is served by, then check eligibility and benefits in that plan manager's system. Sending a claim to the wrong plan manager is the most common, and most avoidable, Louisiana Medicaid denial.
Children through age 20 have comprehensive dental under the EPSDT Dental Program: exams, cleanings, x-rays, fluoride, sealants, fillings, crowns, root canals, extractions, and medically necessary orthodontics with approval.
Adults 21 and older have limited coverage, generally dentures and extractions, unless the member qualifies for a waiver plan (for example the Adult Waiver Plan or Adult Denture Plan through DentaQuest). Under Act 629, effective August 1, 2026, Louisiana Medicaid also covers dental services that are medically necessary to clear a patient for another Medicaid-covered medical procedure, which is a meaningful expansion for adults needing clearance before surgery or other care.
The billing takeaway: child dental is a full book of business if routed to the right plan manager, while adult coverage requires checking the member's specific plan and the medical-necessity clearance rule before you quote treatment.
Enroll with Louisiana Medicaid, then credential with the plan managers you will bill. To see the full Medicaid population you credential with both DentaQuest and MCNA Dental, since members are split between them. Being on the state Medicaid file is not the same as being in-network with a given plan manager.
Each provider and location has to be set up with each plan manager you bill. We handle the full DentaQuest credentialing process and MCNA enrollment and track re-credentialing so your Medicaid network status does not lapse.
Route the claim to the member's plan manager. Confirm whether the patient is with DentaQuest or MCNA, verify eligibility and benefits there, submit any required pre-authorization, then file the claim with that plan manager. For DentaQuest submission detail see our DentaQuest dental claims guide.
Attach what the service requires and respect frequency, age, and waiver rules. File inside the plan manager's timely-filing window; a late Medicaid claim usually cannot be billed to the patient.
Billed to the wrong plan manager. The signature Louisiana mistake, sending a DentaQuest member's claim to MCNA or vice versa.
Adult service outside the limited benefit. Adult work beyond dentures and extractions is denied unless a waiver or the Act 629 medical-necessity rule applies.
Eligibility gaps. Medicaid eligibility changes monthly; verify before every visit.
Missing pre-authorization or documentation on major and orthodontic services.
Verification in Louisiana is a two-part check. First confirm which plan manager serves the member, DentaQuest or MCNA Dental, then verify eligibility and remaining benefits in that plan's system. Eligibility changes month to month, so check before every visit, not just at intake.
Confirm the benefit, not just active status. For a child, confirm EPSDT eligibility and frequency; for an adult, confirm whether coverage is the limited denture-and-extraction benefit, a waiver plan, or an Act 629 medical-necessity clearance. Loading that before the visit keeps the estimate honest and the claim clean.
Two plan managers is the Louisiana trap. The work is identifying each patient's plan manager and routing eligibility, pre-auth, and claims to the right one, every time, across DentaQuest and MCNA, while handling the limited adult benefit and the Act 629 clearance rule correctly.
We verify each Louisiana Medicaid patient's plan manager before the visit, maintain both enrollments, submit clean to the correct plan, and work denials. A free AR analysis shows where your Louisiana Medicaid dollars are leaking.

The most common reasons are billing the wrong plan manager, billing adult services outside the limited benefit, eligibility gaps, and missing pre-authorization or documentation. Verifying the plan manager and eligibility before each visit prevents most of them.
