New Jersey Medicaid enrollment works differently from most states: instead of an online application, you complete a paper enrollment package for your provider type and return it to the state’s fiscal agent. Enrollment is required before credentialing with any NJ FamilyCare managed care plan, and New Jersey offers a managed-care-only option for clinicians who never bill fee-for-service. Here is how New Jersey Medicaid provider enrollment works, step by step, as of 2026.

Who Runs Medicaid Enrollment in New Jersey
New Jersey Medicaid and NJ FamilyCare are administered by the Department of Human Services, Division of Medical Assistance and Health Services (DMAHS). Its fiscal agent, Gainwell Technologies, processes enrollment through the New Jersey Medicaid Management Information System (NJMMIS). Enrollment rules are in N.J.A.C. 10:49-3.2.
Two Ways to Enroll
- Full fee-for-service enrollment, which lets you bill NJ FamilyCare directly and also serves as the basis for managed care credentialing.
- The 21st Century Cures Act application, for clinicians who only participate in managed care plan networks. This option does not allow fee-for-service billing.
How to Enroll, Step by Step
- Download the right package from the NJMMIS provider enrollment page for your provider type, such as physician, dentist, or psychologist and other psychotherapy providers, as an individual or a group. The updated consolidated packages include LCSWs.
- Complete the Provider Application and sign the Provider Agreement. In a group, every practitioner must sign.
- Return the package to Gainwell by email, fax, or mail, using the contact information on the NJMMIS enrollment page.
- Send any requested documents within 35 calendar days.
- Receive written confirmation with a 7-digit Provider Billing Number. Practitioners also receive a Servicing Number.
If an application is denied, you must wait one year before reapplying, so it is worth getting the package right the first time.
Documents and Disclosures
- Social Security number and date of birth.
- Form CMS-1513, the ownership and control disclosure, and the certification of compliance with ownership rules.
- Copies of all licenses, registrations, and board certifications.
- NPI, taxonomy, and DEA number, entered on the application.
- The electronic payment authorization and signature authorization forms.
Is There an Application Fee?
Individual practitioners do not pay an application fee. Listed institutional provider types, such as hospitals, mental health clinics, laboratories, pharmacies, and durable medical equipment suppliers, pay the federal application fee, which is $750 for calendar year 2026, unless they have proof it was already paid to Medicare or another state. Check the NJMMIS announcements page for the current amount and payment instructions before you send payment.
Managed Care: Enrollment Comes First
You must be enrolled with New Jersey Medicaid, through either option above, before you can be credentialed with an NJ FamilyCare managed care organization. For 2026, the five MCOs are Aetna Better Health of New Jersey, Fidelis, Horizon NJ Health, UnitedHealthcare Community Plan, and Wellpoint. All five accept CAQH for credentialing, and you contract with each plan separately.
Behavioral Health Integration
Since January 1, 2025, outpatient mental health and substance use disorder services for NJ FamilyCare managed care members are billed to the MCOs rather than fee-for-service. The MCOs must pay at least the fee-for-service rates for these services. Later phases covering residential services, opioid treatment programs, and the children’s system of care have not been scheduled yet. Only fully licensed clinicians (LCSW, LPC, LMFT, and LCADC) can enroll as individuals; LSWs, LACs, and CADCs cannot. Our New Jersey behavioral health billing page covers the billing side.
Revalidation
New Jersey requires revalidation every five years. Revalidation is submitted as a full enrollment package with the NJMMIS Revalidation Cover Page attached; without the cover page, the request is not processed.
How Long It Takes
New Jersey does not publish a standard processing time for Medicaid enrollment. Under the behavioral health integration rules, MCOs must credential providers within 60 days of receiving a complete application, so plan for a few months from first submission to seeing managed care members.
Common Reasons Applications Stall
- Using the wrong package for the provider type or practice structure.
- A group package that is missing a practitioner’s signature.
- Missing the 35-day window for requested documents.
- Choosing the Cures Act application when the practice also needs to bill fee-for-service.
