Medicaid is the most commonly forgotten enrollment. It is state-run, so there is one application per state, in that state’s own system, on that state’s own timeline (30-120+ days). Nothing carries over from Medicare or CAQH.

The two layers

Most states run Medicaid two ways at once, and you usually need both: The state enrollment is a prerequisite: MCOs verify your state Medicaid ID before contracting. Many MCOs in the payer directory are Medicaid plans (Wellpoint, Healthy Blue, Amerigroup).

What the state application wants

The same file as CAQH plus state extras: entity documents, ownership disclosure (5%+ owners, which matters in MSO/PC structures, disclose the PC ownership accurately), a site visit for some provider types, and fingerprints or background checks in higher-risk categories.

EFT

Most states handle EFT inside the enrollment (Texas example: TMHP PEMS). MCOs handle EFT through their portals like any commercial payer.

Keep it alive

States require periodic revalidation (commonly every 5 years, some more often) and deactivate billing if you miss it. Add it to the compliance calendar. And bill within the state’s timely-filing window, which is often shorter than commercial payers’.
