Lines of business

Medicare Advantage · Medicaid

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.

Coverage by state

Lines of business are contracted per state. Being credentialed for one line in one state does not carry over to another. Data as of July 28, 2026.

We name provider portals but do not link to payer websites — payer URLs move, and a stale link is worse than none. We verify current requirements directly with the payer at the start of every engagement.
