Each plan below has recorded coverage in Tennessee. The lines of business shown are the ones that plan operates in this state — a carrier can run commercial business in one state and Medicaid managed care in the next, and each line is a separate contract.
Coverage data as of July 28, 2026. Payer footprints change with contract cycles; we verify against current payer requirements at the start of any engagement.
National carriers
National carriers credential centrally, so one application generally covers every state you practice in. Network participation and fee schedules are still contracted separately by state and by line of business.

Blue Cross Blue Shield plans
Blue Cross Blue Shield is a federation of independent licensees. Each plan credentials on its own — being in-network with one Blue plan does not make you in-network with another.

Medicaid managed care
Medicaid managed-care organizations contract under a state Medicaid agency. Most require an active state Medicaid provider ID before they will begin credentialing, so the state enrollment has to finish first.

Regional & local plans
Regional plans operate in a limited footprint and more often credential in-house rather than through a delegated CVO. Turnaround varies more than it does with national carriers.

Networks & IPAs
Networks, IPAs, and rental networks aggregate provider panels. Joining one can reach several payers at once, but the contracting party is the network — not the payer whose members you end up seeing.

Government programs
Government programs enroll providers through their own systems rather than commercial credentialing. Enrollment is usually a prerequisite for participating in the managed-care plans built on top of them.
