Where to start your Medicaid application in New Jersey

You apply for Medicaid in New Jersey through the Department of Human Services, Division of Medical Assistance and Health Services (DMAHS). The easiest way to start is online through NJ SNAP, which is New Jersey's benefits portal — it handles Medicaid, food assistance, cash assistance, and other programs in one place. You can also apply by mail, phone, or in person at your county welfare office.

The online portal at njsnap.nj.gov lets you start an application any time, save your progress, and upload documents without leaving home. If you do not have internet access or prefer to speak with someone, call the DMAHS Customer Service Center at 1-609-631-2400 (Monday through Friday, 8 a.m. to 4 p.m.). They can mail you a paper application or schedule an appointment at your county office.

Most people get a decision within 30 days if they submit all required documents upfront. If you are applying because of a change in income or household size, tell DMAHS the date the change happened — this affects when your coverage starts.

Key Takeaways

  • Apply online at njsnap.nj.gov, by phone at 1-609-631-2400, or in person at your county welfare office.
  • You will need proof of income, household size, citizenship or immigration status, and residency in New Jersey.
  • Most decisions come within 30 days if you submit all documents at the time of application.
  • If you are denied, you have 30 days to request a hearing and present more information.
  • Once approved, your coverage can start as early as the first day of the month you applied, depending on your circumstances.

Documents you need before you apply

Have these items ready before you start your application. DMAHS will ask for proof of each one, and missing documents delay your decision. You can upload them during the online application or bring them to your county office.

Income proof is the most important. Bring recent pay stubs (usually the last 30 days), tax returns from the past year, or a letter from your employer stating your salary. If you are self-employed, bring profit-and-loss statements or bank statements showing business income. If you receive Social Security, unemployment, child support, or other benefits, bring the award letter or benefit statement.

Proof of citizenship or immigration status is required. A U.S. birth certificate, passport, or naturalization papers work for citizens. If you are not a citizen, bring your green card, work permit, or other immigration document. Some immigrants without legal status may still be covered under emergency Medicaid for urgent care only.

You also need proof of New Jersey residency (a utility bill, lease, or mortgage statement with your name and address), Social Security numbers for everyone in your household, and identification (driver's license, state ID, or passport). If you are applying on behalf of someone else, bring a power of attorney or guardianship papers.

Income limits and what counts as household income

New Jersey Medicaid has income limits that change each year. For 2024, a single person can earn up to about 138% of the federal poverty level and still be covered. A family of four has a higher limit. These numbers shift annually, so ask DMAHS or check njsnap.nj.gov for the current year's limits.

Income includes wages, self-employment earnings, Social Security, unemployment benefits, child support, and rental income. It does not include food assistance, housing vouchers, or some types of disability payments. If you are over the income limit but have high medical or childcare expenses, you may still be covered — DMAHS subtracts certain costs before calculating your income.

If your income changes after you are approved, report it within 10 days. A raise might end your coverage, but a job loss or reduction could make you newly covered. You do not lose coverage immediately — DMAHS will recalculate and tell you when any change takes effect.

The online application process step by step

Go to njsnap.nj.gov and click "Create Account" if you do not have one. You will set up a username and password, then answer questions about your household size, income, and assets. The form takes 20 to 30 minutes if you have your documents nearby.

Answer honestly about everyone living in your home, including children, partners, and other relatives. DMAHS verifies income through wage records and benefit statements, so discrepancies will delay or deny your case. If you are unsure about a question, leave it blank or write "unsure" — DMAHS will follow up rather than reject you for a mistake.

Upload documents as you go or at the end. The system accepts PDFs, photos, and scans. Make sure the image is clear and shows the full document. Once you submit, you get a confirmation number — save it. You can log back in to check your status or add documents if DMAHS asks for more.

What happens after you submit your application

DMAHS sends you a notice by mail within 30 days. The notice says whether you are approved, denied, or need to send more information. If you are approved, it tells you your coverage start date and how to use your Medicaid card. If you are denied, the notice explains why and tells you how to request a hearing.

If DMAHS asks for more documents, respond within 10 days. You can upload them through njsnap.nj.gov, mail them, fax them to your county office, or bring them in person. Missing the deadline can result in a denial, but you can still request a hearing to explain why you missed it.

Once approved, your coverage usually starts on the first day of the month you applied, or the first day of the month after approval if you applied late in the month. Emergency Medicaid (for urgent care only) may start sooner. You will receive a Medicaid card in the mail within two weeks, but you can use your case number at the doctor or hospital right away.

Applying by mail or phone if you cannot go online

Call 1-609-631-2400 and ask for a paper application. DMAHS will mail it to you, or you can pick one up at your county welfare office. Fill it out completely, attach copies of your documents, and mail it back to the address on the form. Include a cover letter with your phone number so they can contact you if they have questions.

If you apply by phone, a representative will ask the same questions as the online form. Have your documents ready so you can answer about income, household size, and citizenship. The representative will tell you what to mail in and give you a reference number. Write it down — you will need it to check your status.

Paper and phone applications take the same 30 days as online ones, but only if you send all documents at once. If you mail documents separately, each one resets the clock. It is faster to gather everything first, then submit.

What to do if you are denied

If DMAHS denies your application, the notice explains the reason — usually income over the limit, missing proof of citizenship, or not meeting residency requirements. You have 30 days from the date on the notice to request a hearing. Write to your county welfare office or call DMAHS and ask for a fair hearing request form.

At the hearing, you can present new documents, explain your situation, and ask questions about the decision. You can go alone or bring someone to help you — a friend, family member, or legal aid attorney. Legal aid in New Jersey is free if you have low income; call 1-888-529-2643 to find a local office.

If you are still denied after the hearing, you can appeal to the state level. DMAHS will explain this option in the hearing decision. Many people are approved on appeal because they had time to gather better documentation or because the hearing officer found an error in the first decision.

Frequently Asked Questions

Can I apply for Medicaid if I am not a U.S. citizen?

Yes, if you have a green card or work permit. Some immigrants with other visa types may also be covered. If you do not have legal immigration status, you may still be covered under emergency Medicaid for urgent care only. Bring whatever immigration document you have — DMAHS will tell you what you may have access to for.

How long does it take to get a Medicaid card after I am approved?

The card arrives by mail within two weeks, but your coverage starts on the approval date. You can use your case number at doctors and hospitals immediately — you do not have to wait for the physical card.

What if my income is too high but I have large medical bills?

DMAHS may subtract medical expenses, childcare costs, or other allowable deductions before calculating your income. Tell them about these expenses on your application. If you are still over the limit, ask about Medicaid spend-down programs, which let you use medical bills to reduce your countable income.

Do I have to reapply every year?

Yes, Medicaid coverage is renewed once a year. DMAHS will mail you a renewal form before your coverage ends. Fill it out and return it by the deadline, or your coverage will stop. You can renew online, by mail, or by phone using the same process as your original application.

What if my household size or income changes after I am approved?

Report changes within 10 days by logging into njsnap.nj.gov, calling DMAHS, or visiting your county office. A job loss or new baby might increase your coverage or change your copays. Do not wait — reporting late can result in overpayments you have to repay.
