Business & clinical foundation

1Form your entity & get an EIN. Register in New Jersey, get an IRS EIN and W-9.

2Get NPIs. Type 1 for each provider, Type 2 for the organization.

3Secure liability insurance and line up your BCBAs and RBTs (NJ relies on BACB certification rather than a separate state behavior-analyst license).

4Build & attest CAQH profiles.

NJ FamilyCare: the two-step path

NJ FamilyCare (New Jersey Medicaid) has covered ABA for children birth to 21 since April 1, 2020. Becoming a provider is two steps that can run in parallel:

1Get a NJ Medicaid provider number. Submit the ASD Treatment Provider Application (plus addendum and credentials) through Gainwell provider enrollment.

2Contract with the MCOs. Reach out to each managed care organization to complete contracting and credentialing.

Heads up: The two steps can overlap, but MCO contracting may need to pause until your Medicaid provider ID is issued. Start the provider-number application first so it isn't the bottleneck.

The managed care organizations

NJ FamilyCare is delivered through several MCOs, each with its own contracting and authorization process. Credential with the plans your clients are enrolled in:

Aetna Better Health of New Jersey
Wellpoint (formerly Amerigroup) New Jersey
Horizon NJ Health
UnitedHealthcare Community Plan (ABA network managed by Optum)
WellCare

Prior authorization is required for ABA assessment and treatment — submitted to the member's MCO or its behavioral-health vendor. If you're already contracted with an MCO for other services, you may only need to add ABA and request authorization; if not, contact the client's MCO about credentialing or a single-case agreement.
