Wellcare is Centene's brand for Medicare Advantage plans (and some legacy Medicaid plans). There is no single national application — contracting is state-administered, often through the local Centene subsidiary or a state credentialing alliance. Ensure your CAQH profile is current and that Wellcare/Centene is authorized to access it; a credentialing-verification organization (which varies by state) performs primary source verification once and shares it across participating plans. Credentialing approval is required before network participation — contract effective dates and network participation dates may differ. Recredentialing occurs at least every 36 months. Provider services and network numbers vary by state and plan. |

Ensure your CAQH profile is current and that Wellcare/Centene is authorized to access it; a credentialing-verification organization (which varies by state) performs primary source verification once and shares it across participating plans. Credentialing approval is required before network participation — contract effective dates and network participation dates may differ. Recredentialing occurs at least every 36 months. Provider services and network numbers vary by state and plan. |

Common questions about Centene Corporation credentialing
How long does Centene Corporation credentialing take?
Centene Corporation credentialing typically takes 60–90 days from a complete submission to an approved effective date. Incomplete applications are the main cause of delay: a missing document or an unattested CAQH profile restarts the clock rather than pausing it.
Does Centene Corporation require CAQH?
Yes. Centene Corporation pulls provider data from CAQH ProView, so your profile must be complete, attested and shared with Centene Corporation before the application can move. CAQH re-attestation runs on a 120-day cycle, and a lapsed attestation stalls both new enrollments and recredentialing.
Which states does Centene Corporation operate in?
Centene Corporation has credentialing operations in 51 states. 51 of those 51 currently show an open panel. Requirements are not uniform: local plan names, provider portals and state-specific conditions differ, which is what the state-by-state table above records.
