To add a newborn to Medicaid in New Jersey, what you do depends on whether the mother was enrolled in NJ FamilyCare at the time of birth. If she was, the baby is automatically covered from the date of birth through their first birthday under federal law, and you only need to call NJ FamilyCare to get the child their own ID number.1eCFR. 42 CFR 435.117 – Deemed Newborn Eligibility If she wasn’t, you file a regular NJ FamilyCare application that covers the whole family.
When the Mother Was Already on NJ FamilyCare
Federal Medicaid rules treat a baby born to a mother on Medicaid as “deemed” eligible from the moment of birth. The child is handled as if an application had been filed and approved on the day they were born, and that coverage holds until the first birthday regardless of any income or household changes during the year.1eCFR. 42 CFR 435.117 – Deemed Newborn Eligibility
The baby doesn’t get their own Medicaid ID automatically, though. New Jersey lets providers bill for the newborn’s care using the mother’s NJ FamilyCare ID during an initial window that runs from the date of birth through the end of the month in which a 60-day period expires. A baby born January 5th triggers a 60-day window ending March 6th, so providers can use the mother’s ID through March 31st.2Legal Information Institute. New Jersey Code 10:49-2.7 – Applying for Medicaid Eligibility for a Newborn Infant or for an Inpatient Upon Admission to a Hospital After that, providers need the baby’s own Person Number to submit claims.
Call NJ FamilyCare at 1-800-701-0710 (TTY: 711) to report the birth and get the child assigned a Person Number.3NJ FamilyCare. NJ FamilyCare Application for Health Coverage and Help Paying Costs The baby’s eligibility isn’t at risk if you’re late; what’s at risk is smooth billing for the doctors and hospital seeing your child.
When the Mother Wasn’t on NJ FamilyCare
If the mother wasn’t enrolled at the time of birth, the automatic rule doesn’t apply and you file a full NJ FamilyCare application. New Jersey covers children in families earning up to 355% of the federal poverty level, one of the more generous income ceilings in the country, so many middle-income families qualify.4NJ FamilyCare.

Under the state’s Cover All Kids initiative, income-eligible children can enroll in NJ FamilyCare regardless of immigration status.5New Jersey Department of Human Services. Cover All Kids The application and covered services are the same.
Some New Jersey hospitals can start a presumptive eligibility application right after birth, which gives the newborn temporary coverage while the full application is processed. Ask the hospital’s billing or social work office about this before you’re discharged.
Documents to Have Ready
Whether you’re reporting a birth for a deemed-eligible newborn or filing a full application, pull these together:
- Proof of birth: a birth certificate or hospital-issued birth verification with the child’s name and date of birth.6NJ FamilyCare. NJ FamilyCare Application Checklist
- The child’s Social Security number if you have one. You can still apply without it.6NJ FamilyCare. NJ FamilyCare Application Checklist
- The mother’s NJ FamilyCare ID number if she’s enrolled, so the newborn can be linked to her case.
- Proof of address: utility bill, lease, deed, rent receipt, or New Jersey driver’s license.7New Jersey Department of Human Services. Medicaid Document Verification Checklist
- Household income details: employer names, gross pay amounts, and pay frequency for each working household member. Recent pay stubs help. Self-employed applicants need a profit and loss statement.6NJ FamilyCare. NJ FamilyCare Application Checklist
Don’t hold up the application waiting for a missing document. NJ FamilyCare will ask if it needs more.

Picking a Managed Care Plan
After approval, you choose a managed care organization to deliver your child’s care. New Jersey currently offers Aetna, Fidelis Care, Horizon, UnitedHealthcare Community Plan, and Wellpoint.10NJ FamilyCare. Choosing a Health Plan Not every plan operates in every county.
The practical way to decide is to check which plan your child’s pediatrician participates in. If older kids in the household are already on NJ FamilyCare, putting the newborn on the same plan keeps everyone in one network.
Keeping Coverage Past the First Year
Federal law now requires 12 months of continuous eligibility for children under 19 enrolled in Medicaid or CHIP. Once your child is on, their coverage holds for a full year regardless of income changes during that time.11Medicaid.gov. Continuous Eligibility for Medicaid and CHIP Coverage
You still renew each year, and NJ FamilyCare mails a renewal notice before the deadline.12NJ FamilyCare. Who Is Eligible? If you move, update your address right away. A missed renewal letter is the most common reason children lose coverage they still qualify for.
If the Application Is Denied
The denial letter has to explain the reason and your right to appeal.13eCFR. 42 CFR 435.917 – Notice of Agency Decision Concerning Eligibility, Benefits, or Services Read it closely first. Many denials come from missing documents or a data entry error, and resubmitting a corrected application is faster than filing an appeal. If you believe the income determination or another substantive finding is wrong, you have 60 calendar days from the denial to file an internal appeal with the health plan, and further steps are available after that.14NJ FamilyCare.
