Home / Long Island

Long Island Treatment Center is an outpatient rehab on Long Island, located in Hicksville, NY, a short walk from the Hicksville LIRR station. We treat alcohol and drug addiction, along with co-occurring mental health conditions, through partial hospitalization (PHP), intensive outpatient (IOP), evening IOP, standard outpatient and telehealth. Every program we offer is an outpatient service, so clients from across Nassau County and Suffolk County get treatment during the day or evening and sleep in their own beds.

This page explains how outpatient treatment works on Long Island, what to check before choosing a program, and how to reach us from the communities we serve.

Addiction on Long Island: What the Numbers Show

New York recorded an estimated 4,567 overdose deaths in 2024, down sharply from 6,688 the year before, and roughly 77 percent of those deaths involved an opioid such as fentanyl or heroin, according to preliminary CDC data reported by the Governor’s office.

Long Island carries a large share of that burden. The state’s Overdose Death Dashboard counts about 500 overdose deaths in Suffolk County in 2023, the fifth-highest total of any county in New York, and 209 in Nassau County. Both counties are trending down from their 2022 peaks, but Nassau and Suffolk police continue to warn about fentanyl-contaminated cocaine and counterfeit pills, which turn up in local overdose investigations every year.

Treatment demand is just as local. The Office of Addiction Services and Supports (OASAS) reported more than 182,000 admissions to New York treatment programs in 2022. Long Island residents accounted for 14.1 percent of them, and outpatient programs were the single most common level of care, at 39.5 percent of all admissions. Adults aged 25 to 44 made up more than half of the people entering treatment.

Put simply: most people on Long Island who get help for a substance use disorder get it in an outpatient program, close to home.

Signs It Is Time to Seek Help

Substance use disorders develop gradually, and the people closest to the problem are often the last to call it one. The signs and symptoms of drug addiction or alcohol addiction that clinicians look for include:

Tolerance: needing more of the substance to get the same effect.
Withdrawal symptoms: shakiness, sweating, nausea, anxiety or insomnia when use stops, which points to physical dependence.
Cravings that interrupt work, school or sleep.
Loss of control: using more, or for longer, than intended, and failed attempts to cut down.
Consequences that keep piling up: a DWI, missed shifts, money problems or strained relationships, without a change in behavior.
A prior overdose, or Narcan being used on you or someone close to you.

You do not need to hit a bottom to qualify for treatment. Meeting two or three of these criteria is enough for a clinical assessment, and the earlier someone starts, the more options they have. If you are unsure, an assessment with our admissions team is confidential and free.

Outpatient Rehab Programs on Long Island

Outpatient rehab is any program where you attend treatment sessions and then return home. It covers a wide range of intensity, from a few hours a week to full days, and Long Island Treatment Center offers every outpatient level of care under one roof so clients can step down as they progress without changing providers.

Ambulatory Withdrawal Services (Outpatient Detox)

For people who are medically stable but still dependent on alcohol, opioids or benzodiazepines, our ancillary withdrawal services manage withdrawal symptoms with medication and daily check-ins while you remain at home. Anyone at risk of severe withdrawal is referred to a hospital-based program for medically supervised detoxification, or to inpatient rehab, and steps down to our programs afterward.

Partial Hospitalization Program (PHP)

PHP is the most structured outpatient option: treatment most of the day, five days a week, with a mix of individual counseling, group therapy and psychiatric care. It is often the first step for someone leaving residential rehab or inpatient detox, or for someone who needs more than IOP but does not need an overnight bed.

Intensive Outpatient Program (IOP) and Evening IOP

Our IOP on Long Island runs several sessions a week, each a few hours long, and typically lasts three to six months. The evening IOP track follows the same clinical model on a schedule that fits around a job, classes or childcare, which is why it is the most requested program among working adults in Nassau and Suffolk.

Standard Outpatient Program

The outpatient program is weekly individual and group sessions for people who are stable in early recovery and need ongoing support, relapse prevention work and accountability. It is also where many clients land after completing IOP.

Medication-Assisted Treatment (MAT)

MAT combines FDA-approved medication with counseling. For opioid use disorder that means buprenorphine (Suboxone, Sublocade) or naltrexone (Vivitrol); for alcohol use disorder, naltrexone or acamprosate. Medication is prescribed and monitored by our medical staff and can run alongside any program level.

Telehealth

Individual and group sessions are available by secure video for clients who cannot travel to Hicksville every session. Telehealth services are used for step-down care, for weather or transportation problems, and for clients farther out on the island.

How to Verify a Rehab Is Licensed and Accredited

Two credentials matter most for an outpatient program in New York, and you can check both yourself in a few minutes.

OASAS certification. Every legitimate addiction treatment program in the state is certified by OASAS and listed in the OASAS Provider and Program Search. Long Island Treatment Center is an OASAS-certified Part 822 outpatient provider. If a facility is not in that directory, it is not licensed to treat substance use disorders in New York.

Joint Commission accreditation. The Joint Commission is a national accrediting body that audits treatment programs against standards for patient safety, clinical quality and staff credentials. Accreditation is voluntary and has to be renewed, so it signals a program that invites outside scrutiny. Our accreditation can be confirmed on the Joint Commission Quality Check site.

Who is treating you. Ask what licenses the clinical staff hold. At LITC, care is delivered by a team of board-certified physicians, psychiatrists and New York-licensed counselors and therapists, and every program is built on evidence-based treatment rather than untested approaches.

Beyond credentials, three questions separate good programs from the rest: Does the program treat co-occurring mental health conditions on site? Is there a written treatment plan that gets updated as you progress? And is there a plan for what happens after discharge?

Individualized Treatment, Including Dual Diagnosis

Every client at Long Island Treatment Center starts with a clinical assessment that determines the right level of care, screens for co-occurring disorders and produces an individualized treatment plan. That plan is reviewed regularly and changes as you do; the program length is set by progress, not by a calendar.

Co-occurring mental health conditions are the rule, not the exception. Research puts the rate of dual diagnosis among people with a substance use disorder at more than a third, with anxiety, depression and PTSD the most common. Our dual diagnosis treatment on Long Island addresses both conditions together, with psychiatric services available in-house rather than through an outside referral.

Therapy is where the work happens. Our clinicians use therapeutic interventions including individual therapy, group therapy, family therapy and couples therapy, built on cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT) and motivational approaches. The goal is a set of skills you can use when a craving hits in a Massapequa parking lot, not just in a group room.

Support and Wellness Services Beyond Therapy

Outpatient treatment works when the rest of your life supports it. Alongside the core programs, Long Island Treatment Center offers:

Specialty groups and tracks, including a women’s program, problem gambling treatment, a kosher treatment plan and a 12-step track.
Family involvement through family counseling and education, so the people you live with understand recovery and their role in it.
Psychiatric services for medication management of depression, anxiety and other co-occurring conditions.
Relapse prevention and aftercare: a written relapse prevention plan and discharge planning before you finish, and an aftercare program that keeps you connected.
An alumni community with regular in-person and virtual meetings and sober social outings, so support continues after the program ends.
Referrals for sober living when a client’s home environment is not safe for early recovery.

Insurance and Payment Options

Which insurance plans cover outpatient rehab on Long Island?

Long Island Treatment Center accepts most major commercial insurance plans, including Blue Cross Blue Shield, and works with many union plans common on Long Island. Under the Affordable Care Act and federal parity law, substance use treatment is an essential health benefit, so PHP, IOP, outpatient counseling and MAT are covered services on nearly every plan sold in New York. What varies is your deductible, copay and whether the plan requires prior authorization for a given level of care.

How do I find out what my plan covers?

You do not have to call your insurer yourself. Our admissions team runs a free, confidential insurance verification, usually the same day, and explains your out-of-pocket costs before you commit to anything. For clients without coverage, self-pay rates and payment plans are available; ask admissions for current pricing. More detail is on our insurance coverage page.

Real Reviews from Real Clients

Client reviews of Long Island Treatment Center on Google and independent treatment directories average above 4.5 stars, and the themes repeat: staff who are professional without being clinical, a non-judgmental atmosphere, counselors who remember your name and your story, and an evening schedule that made it possible to keep a job while getting treatment.

Testimonials describe individual experiences, and results vary. The most reliable predictor of a good outcome is finishing the program you start, which is why we put so much weight on scheduling and family involvement.

Getting to Our Hicksville Treatment Center

Long Island Treatment Center is an addiction treatment center at 100 W Nicholai St in Hicksville, in central Nassau County. The location was chosen for access: Hicksville station is one of the busiest stops on the Long Island Rail Road, where the Ronkonkoma, Port Jefferson and Main Line branches meet, so clients from Suffolk and from the city can reach us by train without a car. By road, the treatment facility is minutes from the Northern State Parkway, the LIE (I-495) and Route 106/107, with parking on site.

Being local matters for outpatient care in a way it does not for a 30-day residential stay. You are commuting to treatment several times a week for months, and the support network you build in group is one you can keep after discharge. Choosing a program on Long Island also makes it easier to involve family and to use in-network coverage.

Nassau County

Most of our clients come from central and southern Nassau. Hicksville itself, and the neighboring communities, are within a 10 to 20 minute drive:

Suffolk County

Western Suffolk is a 20 to 30 minute drive along the Northern State or Southern State, or a short ride on the Ronkonkoma branch. Evening IOP and telehealth sessions make the commute manageable for clients from:

Frequently Asked Questions

Does Long Island Treatment Center offer inpatient or residential rehab?

No. We are an outpatient provider. If an assessment shows you need inpatient treatment or residential rehab first, we help arrange it and then provide the step-down care (PHP, IOP, outpatient) once you return to Long Island.

How long does outpatient rehab take?

PHP commonly runs two to six weeks, IOP three to six months, and standard outpatient as long as it is useful. Most clients move through two or three levels, and total time in treatment of 90 days or more is associated with better outcomes.

Can I keep working while in treatment?

Yes. Evening IOP and telehealth exist for exactly that reason. Many clients also use job-protected leave under the FMLA for the PHP phase and return to work during IOP.

Is treatment confidential?

Yes. Your treatment records are protected by HIPAA and by federal confidentiality rules specific to substance use treatment (42 CFR Part 2), which are stricter than ordinary medical privacy. Nothing is shared with an employer, a court or a family member without your written consent, except where the law requires it.
