This plan is run by HCSC, one company operating the Blues of Illinois, Texas, Oklahoma, New Mexico, and Montana on the same flow: fill out the online Provider Onboarding Form, pass the eligibility check, receive the emailed contract, then credentialing runs from your CAQH authorization. Track with the Case Status Checker using the case number from your confirmation email.
Behavioral health routing: Behavioral health care management is integrated with the medical program. The trap is HMO members: their behavioral services are managed by the member's medical group or IPA, so HMO network access means contracting with a participating group, not HCSC directly.
The stall to avoid: Keep the case number from the confirmation email: the Case Status Checker is the only self service status view.
