Where and how to start your Medicaid application in New Jersey

You apply for Medicaid in New Jersey through NJ SNAP, which is the state's benefits portal that handles Medicaid, SNAP (food assistance), and other programs. You can apply online at njsnap.nj.gov, by mail, in person at your county welfare office, or by phone. The online route is fastest — you can submit your application in one sitting and get a decision within 30 days in most cases.

If you apply online, you will create an account, fill out your household information, income, and assets, upload documents, and submit. The state will contact you if they need more information. If you apply by mail or phone, you will need to request an application form from your county welfare office or call the NJ SNAP customer service line. In-person applications at your county office are also an option if you prefer to hand-deliver documents or need help filling out the form.

Your county welfare office is your main point of contact throughout the process. You can find your office location and phone number on the NJ Department of Human Services website by entering your county name. Having your office's direct number is useful because they can tell you the current status of your application and what documents they still need from you.

Key Takeaways

  • Apply online at njsnap.nj.gov, by mail to your county welfare office, by phone, or in person — online is usually fastest and takes about 30 days.
  • You will need to provide proof of income (pay stubs, tax returns, or a letter from your employer), proof of residency (utility bill or lease), and proof of citizenship or immigration status.
  • Your income limit depends on your household size; New Jersey uses federal poverty guidelines, and limits change each year.
  • Once approved, your Medicaid coverage starts on the first day of the month after approval, and you receive a card in the mail within one to two weeks.
  • If you are denied, you have the right to request a fair hearing within 30 days of the denial letter.

Documents you need to have ready before you apply

Gather these documents before you start your application, whether online or on paper. You will need proof of income — recent pay stubs (usually the last 30 days), tax returns from the past year, or a letter from your employer on company letterhead stating your job title and monthly income. If you are self-employed, bring tax returns and bank statements. If you receive unemployment, Social Security, or other benefits, bring the award letter or most recent statement.

You will also need proof of residency — a utility bill, lease agreement, mortgage statement, or property tax bill with your name and current address. The document must be dated within the last 60 days. For citizenship or immigration status, bring your birth certificate, passport, green card, or other immigration document. If you are a non-citizen, you may still be found to meet other Medicaid categories, so do not skip the application.

Have your Social Security number and the Social Security numbers of everyone in your household. If anyone in your household does not have a number, you will need to apply for one before or during the Medicaid process. You will also need to list any assets you own — bank accounts, vehicles, property — so have recent bank statements or account numbers ready. New Jersey has asset limits that vary by household type, and the state will ask about these.

Income limits and household size rules

New Jersey Medicaid income limits are based on the federal poverty level, which changes each year. For 2024, the limit for a single person is roughly 138% of the federal poverty line, and for a family of four it is higher. The exact dollar amount changes annually, so the state publishes updated limits each January. You can find the current limits on the NJ Department of Human Services website or by calling your county welfare office.

Your household size includes you, your spouse if you are married, and any children under 19 who live with you. Other relatives or unrelated people living in your home do not count as part of your household for Medicaid purposes. If you have a child who lives with you part-time, the rules depend on custody and support arrangements — your county office can clarify this for your situation.

Income is counted as gross income before taxes. This includes wages, self-employment income, rental income, Social Security, unemployment, child support, and most other sources. Some income is not counted — for example, the first $20 of unearned income per month and the first $65 of earned income per month are typically excluded, though these amounts can vary. If your income is close to the limit, ask your county office to calculate whether you meet the threshold.

What happens after you submit your application

After you submit your application, the state sends you a notice within 10 days confirming they received it. This notice includes a case number and the name of your caseworker. If you applied online, you can log into your njsnap.nj.gov account to check the status of your application at any time. If you applied by mail or phone, your caseworker will contact you if they need more information.

The state has 30 days to make a decision on your application. During this time, they may ask you to provide additional documents or clarify information. If they ask for documents, they will give you a deadline — usually 10 to 14 days. If you miss the deadline, your application may be denied, but you can reapply. If you need more time, call your caseworker and ask for an extension; they can often grant one.

Once you are approved, you will receive an approval notice in the mail. Your Medicaid coverage begins on the first day of the month after approval. You will receive a Medicaid card in the mail within one to two weeks. Use this card at doctors, hospitals, and pharmacies. If you do not receive your card within three weeks, call your county office to request a replacement.

Renewing your Medicaid coverage each year

Your Medicaid coverage must be renewed once a year. New Jersey will send you a renewal notice in the mail about 60 days before your coverage ends. The notice will tell you how to renew — usually online through njsnap.nj.gov, by mail, or by phone. You do not have to wait for the notice; you can renew early by contacting your county office.

To renew, you will need to provide updated income and household information. If nothing has changed, you can often renew by mail or online without submitting new documents. If your income or household size has changed, you will need to report this and may need to submit new proof. If you miss your renewal deadline, your coverage will end, but you can reapply at any time.

If your income increases above the Medicaid limit, you will lose coverage. However, New Jersey has a program called Medicaid Buy-In that allows some people with higher incomes to keep coverage by paying a small premium. Ask your caseworker if you might be found to meet this option if your income rises.

What to do if your application is denied

If your application is denied, you will receive a denial notice in the mail explaining the reason. Common reasons include income above the limit, failure to provide required documents, or not meeting the citizenship requirement. Read the notice carefully to understand why you were denied.

You have the right to request a fair hearing within 30 days of the denial notice. A fair hearing is a chance to present your case to an independent hearing officer. To request one, contact your county welfare office or call the NJ SNAP customer service line and ask for a fair hearing. You can represent yourself or bring someone to help you. At the hearing, you can present documents, explain your situation, and ask questions about the denial.

You can also reapply at any time. If your situation has changed — for example, your income has gone down or you now have proof of citizenship — a new application may be approved. When you reapply, mention that you were previously denied and explain what has changed.

Frequently Asked Questions

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

Yes. New Jersey Medicaid covers certain non-citizens, including lawful permanent residents (green card holders), refugees, asylees, and some other immigration statuses. You will need to provide immigration documents. If you are undocumented, you may not meet the standard Medicaid category, but New Jersey offers emergency Medicaid for urgent medical conditions regardless of immigration status. Ask your county office which category you might meet.

How long does it take to get approved for Medicaid in New Jersey?

The state has 30 days to decide your application from the date you submit it. In practice, many applications are approved within two to three weeks if all documents are provided upfront. If the state asks for more information, the clock pauses while you gather and submit documents. Once approved, your coverage starts on the first day of the next month.

What if my income changes after I am approved?

You must report income changes to your county welfare office. If your income increases above the Medicaid limit, your coverage will end at the end of that month. If your income decreases, you can request a mid-year review to see if you still meet the income limit. Report changes within 10 days of when they happen to avoid overpayment issues.

Do I have to pay anything for Medicaid in New Jersey?

Standard Medicaid in New Jersey has no monthly premium or copay for most services. Some services may have small copays (usually $1 to $3), but preventive care, emergency services, and most doctor visits are free. If you are found to meet the Medicaid Buy-In program due to higher income, you would pay a small monthly premium, but this is optional.

What if I lose my Medicaid card or need a replacement?

Call your county welfare office or log into your njsnap.nj.gov account and request a replacement card. The new card will arrive in the mail within one to two weeks. In the meantime, you can use your case number as proof of coverage at most doctors and hospitals. If you need coverage urgently, ask your provider to verify your coverage by calling the Medicaid number on your old card or contacting the state directly.
