Oklahoma SoonerSelect Credentialing: The Transition Explained

Oklahoma moved most of its Medicaid population into managed care in 2024, and that change caught a lot of providers off guard: being a SoonerCare provider no longer means you can bill for most of your Medicaid patients. Under SoonerSelect, the state’s Medicaid managed care program, most SoonerCare members now get their care through one of three private health plans, and to bill for those patients you have to contract with the plans directly, on top of your state enrollment. A provider who’s still relying on their old SoonerCare enrollment alone will find claims for SoonerSelect members denying.

For behavioral health providers especially, this matters, because SoonerSelect folds behavioral health into the same health plans as physical care rather than carving it out separately. That’s structurally simpler than the carve-out model many states use, but it still means a second layer of contracting that didn’t exist before the transition. This post explains how SoonerSelect works, the two-step enrollment it requires, and what trips providers up.

What SoonerSelect Actually Is

SoonerSelect is Oklahoma’s Medicaid managed care program, administered by the Oklahoma Health Care Authority (OHCA). Instead of the state paying providers directly through traditional fee-for-service SoonerCare, most members now receive their benefits through a private health plan that manages and pays for their care.

SoonerSelect health plans cover medically necessary prescriptions, health services, and behavioral health services, with dental handled through separate SoonerSelect dental plans. There are three contracted health plans statewide:

• Aetna Better Health of Oklahoma
• Humana Healthy Horizons in Oklahoma
• Oklahoma Complete Health

The population affected is large. The program covers non-disabled children including those in foster care, low-income parents, pregnant women, and non-disabled adults ages 19 to 64, which is the bulk of the SoonerCare rolls. Each health plan runs its own provider network, so which plan a patient is enrolled in determines who pays for their care and whether you’re in network for them.

One point that helps behavioral health providers: SoonerSelect does not carve behavioral health out to a separate managed behavioral health organization. The health plans cover behavioral health alongside physical and pharmacy benefits, which is the same integrated approach TennCare uses and simpler than the separate-panel model, a contrast we cover in our guide to Tennessee behavioral health credentialing. When you contract with a SoonerSelect plan, that contract covers your behavioral health services under it.

The Two-Step Enrollment SoonerSelect Requires

Getting paid for SoonerSelect members takes two distinct steps, and the mistake that costs providers the most is assuming the first step is enough. It isn’t.

Step one: enroll with Oklahoma Medicaid through OHCA. You complete provider enrollment through OHCA’s electronic provider enrollment portal to become a SoonerCare provider. This is the foundation and it’s still required, it establishes you in the state Medicaid system and is the prerequisite for everything that follows.

Step two: contract with the SoonerSelect health plans. OHCA enrollment alone does not let you bill SoonerSelect members. To do that, you contract and credential separately with each health plan whose members you want to see. OHCA encourages providers to contract with all three SoonerSelect health plans to continue serving all the SoonerCare members who transitioned to SoonerSelect. Each plan runs its own contracting and credentialing process, its own provider portal, and its own claims system.

Because members are distributed across all three plans, contracting with only one limits you to that plan’s members. A behavioral health group that wants to keep serving its full SoonerCare patient base after the transition generally needs to be contracted with all three, Aetna, Humana, and Oklahoma Complete Health, not just one.

The plans credential off your CAQH profile the same way commercial payers do, so a complete, attested CAQH profile is a prerequisite for the second step. The same 120-day attestation discipline from our CAQH ProView guide applies here, a lapsed attestation stalls plan contracting.

How SoonerSelect Enrollment Works, Step by Step

The full path to billing SoonerSelect members follows a clear sequence, even with multiple parties involved.

First, complete OHCA provider enrollment through the electronic provider enrollment portal to establish or confirm your SoonerCare provider status. Second, make sure your CAQH profile is complete and attested, since the health plans draw on it during credentialing. Third, contact each of the three SoonerSelect health plans to begin contracting and credentialing, reviewing and signing each plan’s provider agreement. Fourth, once contracted, verify member eligibility and plan assignment before billing, OHCA provides the provider portal, the provider helpline, and Availity to confirm which plan a member is enrolled in, and each plan processes its own claims and prior authorizations.

Because Oklahoma runs this as managed care layered on state enrollment, it’s more involved than a single fee-for-service Medicaid enrollment. The broader mechanics of state Medicaid enrollment are covered in our Medicaid provider enrollment guide; SoonerSelect is the Oklahoma-specific managed care layer that sits on top of it, the same two-layer structure that Arkansas uses with its PASSE program.

What Trips Providers Up

A few recurring issues account for most of the lost revenue in the SoonerSelect transition.

Assuming SoonerCare enrollment is enough. The most common and costly error. A provider stays enrolled with OHCA, keeps seeing their Medicaid patients, and finds claims denying because those patients are now in SoonerSelect plans the provider never contracted with. State enrollment is the prerequisite, not permission to bill managed care members.

Contracting with only one plan. Members are spread across Aetna, Humana, and Oklahoma Complete Health. A provider contracted with one can bill only that plan’s members and is out of network for the other two-thirds of the transitioned population. Reaching your full patient base means contracting with all three.

Not verifying plan assignment before the visit. Because a patient’s plan determines who pays, billing without confirming which SoonerSelect plan they’re in, and whether you’re contracted with it, produces denials. Verifying eligibility and plan assignment through OHCA’s tools before the visit prevents this.

Letting CAQH lapse. The plans credential off CAQH, so an incomplete or unattested profile stalls contracting at step two. This is the same failure mode behind many credentialing application denials.

Underestimating the multi-plan credentialing load. Three plan contracts plus OHCA enrollment means four separate processes, each with its own paperwork, timeline, and revalidation cycle, multiplied across every provider in a group. When we take on an Oklahoma behavioral health group mid-transition, the most common thing we find is a practice enrolled with OHCA and contracted with one plan, quietly out of network for the majority of its own Medicaid patients and not realizing it until the denials pile up.

Frequently Asked Questions

Get Contracted Across Every SoonerSelect Plan

The SoonerSelect transition turned a single Medicaid enrollment into a two-step process, and the providers losing revenue are the ones still billing on their old SoonerCare enrollment alone or contracted with just one plan. Getting enrolled with OHCA and contracted with all three health plans, cleanly and in the right order, is what lets you bill your full Medicaid patient base again.

MedBillingTech handles Oklahoma behavioral health credentialing across the full stack: OHCA enrollment, contracting and credentialing with Aetna, Humana, and Oklahoma Complete Health, CAQH management, and revalidation tracking across every plan. Flat fee of $150 per application, with a 97% client retention rate. Mark Wood, our COO, has spent more than 20 years in payer enrollment.
