The United States has no single public health system for working-age adults. Most people get insurance through an employer; others buy a plan on their state marketplace; public programs such as Medicaid, the Essential Plan and Child Health Plus cover people with lower incomes and children. Insurance matters: a hospital emergency department must examine and stabilize you regardless of your ability to pay, but you can still receive the bill.

This guide focuses on New York, where the marketplace is NY State of Health (855-355-5777).

Before you start

  • A New York address for a NY State of Health plan
  • Your immigration documents and income information

Documents you need

  • Passport

    required
  • I-94 record or other immigration document (non-citizens)

    optional
  • Job offer or pay information (income)

    optional
  • Proof of New York address

    optional

Words you will see on every plan

  • Premium: what you (and your employer) pay each month for the plan.
  • Deductible: what you pay for covered care each year before the plan starts paying for most services.
  • Copay and coinsurance: your share of each visit or bill after the deductible.
  • Network: the doctors and hospitals that have a contract with your plan. Seeing an out-of-network provider usually costs much more.
  • Out-of-pocket maximum: the most you pay in a year for covered in-network care.

Employer plans

Most employers offer a group plan and pay part of the premium, which is deducted from your salary. Your employer decides who is eligible, but once you are otherwise eligible, a waiting period may not exceed 90 days. Ask HR for the enrollment deadline, the plan documents and the provider network, and add your spouse and children when you first enroll; if you lose employer coverage later, you usually have 30 days to join another group plan.

If you leave a job at an employer with 20 or more employees, you can often keep the group plan for a limited time under COBRA, but you then pay the full premium yourself.

Buying a plan on NY State of Health

If you have no employer plan, you can buy a Qualified Health Plan on NY State of Health if you live in New York, are a US citizen or lawfully present, and do not qualify for Medicaid, the Essential Plan or Child Health Plus. Every plan covers preventive care and pre-existing conditions.

  • Open enrollment is held once a year. For 2026 coverage it ended on 31 January 2026, you had to enroll by 15 December 2025 for coverage from 1 January, and existing enrollees could renew or change plans from 16 November 2025. Check NY State of Health for the 2027 dates.
  • Outside open enrollment, moving and other life events usually give you 60 days to enroll (a Special Enrollment Period). Medicaid, the Essential Plan and Child Health Plus are open all year to those who qualify.
  • Help: apply online, call 855-355-5777 (TTY 800-662-1220), or call 311 for free help from an enrollment counselor in your language.

Changes for immigrants in 2026 and 2027

Federal law H.R. 1 (signed in July 2025) changes who can get financial help:

  • From 1 January 2027, premium tax credits (the federal subsidy that lowers marketplace premiums) are limited to lawful permanent residents, Cuban and Haitian entrants and COFA migrants. Holders of nonimmigrant visas such as H-1B or F-1 can still buy a marketplace plan, but without this subsidy.
  • New York's Essential Plan was restructured: about 450,000 people with incomes between 200% and 250% of the federal poverty level lost eligibility from 1 July 2026 and were moved toward Qualified Health Plans, while about 1.3 million people below 200% kept coverage.

If you rely on a public program or a subsidy, check your eligibility with NY State of Health before you renew, and do not stop coverage or services without advice.

Children – Child Health Plus

Child Health Plus covers children aged 18 and under who live in New York, have no other insurance and do not qualify for Medicaid, regardless of immigration status. Most families pay a premium of $0 to $60 a month depending on income, with no copays (2026). Apply through NY State of Health.

Students and exchange visitors

Many universities require students to buy the school health plan or show equivalent cover. J-1 exchange visitors and their J-2 dependents must have insurance for the whole program with at least $100,000 of medical benefits per accident or illness, $50,000 for medical evacuation, $25,000 for repatriation of remains and a deductible of no more than $500 per accident or illness. Ask your sponsor or school before you buy a separate plan.

If you cannot get insurance – NYC Care

NYC Care gives New Yorkers who do not qualify for or cannot afford health insurance access to low-cost and no-cost care at NYC Health + Hospitals, with a member card, a primary care doctor and affordable medicines. There are no premiums or monthly fees, fees are on a sliding scale from $0, and NYC Care does not ask about immigration status. Call 646-NYC-CARE (646-692-2273) to enroll.

Emergencies and surprise bills

In an emergency, call 911 or go to the nearest emergency department. Hospitals that take part in Medicare must give a medical screening exam and stabilizing treatment regardless of your ability to pay. The federal No Surprises Act protects insured patients from most surprise out-of-network bills for emergency care, and if you are uninsured or paying yourself, providers generally must give you a good faith estimate; you may be able to dispute a bill that is at least $400 above it. Questions: 1-800-985-3059.

Watch out

Being uninsured can leave you with very high bills even after short hospital stays.

From 2027 most nonimmigrant visa holders cannot get federal premium subsidies on the marketplace; compare the full price of plans.

Check that your doctor is in your plan's network before booking, except in an emergency.

Common mistakes

  • Missing the employer enrollment deadline and waiting until the next annual enrollment period.
  • Letting the 60-day Special Enrollment Period after a move pass without choosing a plan.
  • Assuming travel insurance from home covers everyday care in the United States.

Tips

  • Ask HR whether the employer plan covers dental and vision care; these are often separate plans.
  • Keep your insurance card with you and add the plan's nurse line and urgent care information to your phone.
  • Call 311 and ask for help with health insurance enrollment; counselors are free and speak many languages.

Frequently asked questions

Editorial answers written by our team, based on the sources below.

Is there free public health care for adults in New York City?

There is no general free system, but NYC Health + Hospitals runs more than 70 locations and offers low-cost care. People who cannot get or afford insurance can join NYC Care, which charges sliding-scale fees from $0 and does not ask about immigration status.

My employer plan starts after a waiting period. What do I do until then?

Waiting periods may not be longer than 90 days. For the gap, consider a short-term plan or travel cover, or ask NY State of Health whether you qualify for a marketplace plan for those months.

In your plan

  • Enroll in health insurance
  • Make sure you are insured from the day you arrive
  • Choose a primary care doctor in your insurance network
  • Estimate your New York City budget, including move-in costs
