Frequently asked questions about Northwell Health System
Answered from this center's own federal listing — not from marketing copy.
Northwell Health System appears in SAMHSA's federal treatment locator, the U.S. government's official directory of licensed substance-use providers, and reports the following credentials: The Joint Commission, State-licensed and Federally Qualified Health Center. You can verify this yourself at findtreatment.gov — we are not affiliated with this center and are not paid by it.
According to its federal listing, Northwell Health System accepts Medicaid (New York Medicaid), Medicare, private insurance, military insurance / TRICARE and self-payment. It also offers a sliding fee scale, meaning what you pay is based on your income. Coverage details change, so confirm with the center at 516-742-4015 before you rely on it.
We don't publish prices, because no directory can quote you an accurate one — the real cost depends on your coverage, the level of care, and how long you stay. What we can tell you is that Northwell Health System reports a sliding fee scale based on income and accepts Medicaid, so a lack of money is not automatically a closed door. Ask them directly what you would pay.
Northwell Health System reports offering Outpatient care. The right level depends on how severe your use is and whether withdrawal needs medical supervision — alcohol and benzodiazepine withdrawal in particular can be dangerous without it.
Its listed treatment approaches include cognitive behavioral therapy, motivational interviewing, relapse prevention, substance use disorder counseling, telemedicine/telehealth therapy and trauma-related counseling. Evidence-based approaches such as cognitive behavioral therapy, contingency management and motivational interviewing are what research consistently supports — it's fair to ask any center which of these it actually practices.
