Summary
Oklahoma Health Care Authority now allows providers to submit contract applications to OHCA and credentialing requests to SoonerSelect managed care plans simultaneously to streamline the credentialing process. During the credentialing period, claims will be reimbursed at 90% (non-participating rate) until credentialing is complete, then at 100% (participating rate).
Action Required
Immediately: Billing team should update expectations for Oklahoma Medicaid claims reimbursement rates - expect 90% reimbursement for new providers during credentialing period until provider credentialing is complete with SoonerSelect plans (Aetna Better Health, Humana Healthy Horizons, Oklahoma Complete Health). Monitor reimbursement rates and follow up if rates don't increase to 100% after credentialing completion. Providers seeking credentialing should contact the appropriate CE provider relations teams for specific requirements.
