Drug and Alcohol Rehab in New Jersey: Levels of Care, Paying for It, and How to Choose

Rehab in New Jersey by the numbers

Two public sources describe the system. SAMHSA’s national facility survey counted 413 New Jersey substance use treatment facilities on March 29, 2024, with 36,565 people in treatment that day. 360 offered outpatient care, 61 offered non-hospital residential care and 22 offered hospital inpatient care. The state’s own data, from the Division of Mental Health and Addiction Services, counted 81,217 treatment admissions in 2024 for 43,415 people.

Read the table with three limits in mind:

• The survey counts facilities that answered it (91.4 percent did), and one facility can offer several levels, so the rows do not add up to 413.
• The admissions figures come from programs that report to the state system. Medicaid was listed for 71 percent of 2024 admissions, so the data lean toward publicly funded care.
• Hospital detox units barely appear in the state admissions data (55 in 2024). Do not read that row as a measure of hospital detox capacity. Our directory of 47 licensed detox programs lists hospital units by county. It is built from state licenses and hospital units, not from the survey, so its count differs.

What people enter treatment for

Alcohol was the most common primary substance at admission in New Jersey in 2024: 34,071 admissions, 42 percent. Heroin followed with 23,408 (29 percent), then cocaine with 7,139 (9 percent), other opioids with 5,946 (7 percent), marijuana with 5,246 (6 percent), and methamphetamine and other stimulants with 2,605 (3 percent).

The levels of care, in order

Clinicians match people to a level using the ASAM Criteria, which ASAM describes as the most widely used set of standards for addiction care placement. The match depends on withdrawal risk, medical and psychiatric problems, and how safe and supported you are at home. People can move down the levels as they stabilize.

1. Detox (withdrawal management)

Detox gets you through withdrawal safely. It runs in a hospital unit, in a residential facility with 24-hour nursing, or as an outpatient. ASAM’s alcohol withdrawal guideline says outpatient withdrawal management can typically be done safely for people with limited or mitigated risk factors. Past withdrawal seizures or delirium tremens, other substances, serious medical illness, psychiatric symptoms or little support at home push toward inpatient care.

Detox is not rehab. It treats the body’s withdrawal, not the addiction. In the state’s 2024 data, 48.3 percent of discharges from residential and hospital detox were transfers to another level of care at the same agency and clinic site, and 18.8 percent refused continuing care. Ask every detox program what happens on the day you leave. Our guides by substance cover alcohol, opioid, benzodiazepine, stimulant and polysubstance detox.

2. Residential (inpatient) rehab

You live at the facility and get treatment most of the day, with staff on site around the clock. This is what most people mean by inpatient rehab in New Jersey. Short-term programs run 30 days or less, and the state’s median stay in 2024 was 19 days. Long-term programs run more than 30 days. Our residential treatment guide covers who needs it and how insurers review the length of stay.

3. Partial hospitalization (PHP)

A full day of treatment, most days of the week, and you sleep at home. Medicare, for example, requires at least 20 hours of services a week for partial hospitalization. It can serve as a step down from residential care. See our PHP guide.

4. Intensive outpatient (IOP)

Several sessions a week, built around work or school. Medicare requires a physician to find that a patient needs at least nine hours a week. In New Jersey it is one of the two most common levels of care at admission, with 15,992 admissions in 2024. See our IOP guide.

5. Outpatient care

Counseling, usually once or twice a week, often with medication. It is where many people start if their use has not reached the point of withdrawal. See our outpatient guide.

6. Medication and recovery support

Medication can run alongside every level, not only after it. For opioid use disorder that means buprenorphine, methadone or naltrexone. For alcohol use disorder, naltrexone, acamprosate or disulfiram. Our MAT guide explains how to start one in New Jersey, and our aftercare guide covers peer support, recovery housing and the year after treatment.

Alcohol rehab and drug rehab: what differs

Most New Jersey programs treat both. In SAMHSA’s 2024 survey, 279 of the 313 New Jersey facilities that answered the question were treating clients with both alcohol and other drug problems. The real differences are medical:

• Alcohol withdrawal can be dangerous. Seizures and delirium tremens are why a clinician, not you, should decide whether detox happens at home, in a residential program or in a hospital.
• Ask about alcohol medications. Of the 413 New Jersey facilities in the survey, 243 offered oral naltrexone, 138 offered acamprosate and 112 offered disulfiram. Ask whether the program prescribes them.
• Opioid treatment should include medication. 249 facilities offered buprenorphine with naloxone and 46 offered methadone. A program that will not continue the buprenorphine or methadone you already take is the wrong program.

How to pay for rehab in New Jersey

Your coverage type decides which door you use. In SAMHSA’s survey, 328 of 413 New Jersey facilities accepted private insurance, 279 accepted Medicaid and 189 accepted Medicare.

Commercial insurance

Fully insured New Jersey plans and the State Health Benefits and School Employees’ plans cannot require prior authorization for the first 180 days per plan year of in-network treatment your own physician, psychologist or psychiatrist finds medically necessary. Self-funded employer plans, Medicare and Medicaid are not covered by that rule. For the first 28 days of inpatient treatment in a plan year, the law also bars concurrent and retrospective review. The state Department of Banking and Insurance says ID cards issued in New Jersey must state whether the coverage is fully insured or self-funded. Most self-funded employer plans are still bound by federal parity law. Our NJ parity law guide explains both rules. Carrier guides: Horizon BCBS, AmeriHealth NJ, Aetna and Cigna.

NJ FamilyCare (Medicaid)

Since January 1, 2025, your NJ FamilyCare plan manages most outpatient behavioral health care itself, including substance use counseling, intensive outpatient, partial care and ambulatory (outpatient) detox. Hospital-based inpatient detox also goes through the plan. For most members, residential detox and short- and long-term residential treatment are still paid by the state directly, which Medicaid calls fee-for-service, and authorized through the IME Addictions Access Center at 1-844-276-2777. The state has delayed moving residential care into the plans until January 2027. Members enrolled through the Division of Developmental Disabilities, MLTSS or a FIDE SNP start with their plan for residential care too. Our NJ FamilyCare guide lists each plan’s member services number.

Medicare

Medicare is not covered by the New Jersey no-prior-authorization rule, and Medicare Advantage plans can require prior authorization. Original Medicare covers hospital inpatient care, partial hospitalization and, since 2024, intensive outpatient programs. Our Medicare guide explains each part and the gap for freestanding residential rehab.

State funding when there is no insurance

Call the IME Addictions Access Center at 1-844-276-2777. It answers 24/7, screens callers, and its financial screening checks whether you can get state-funded treatment. You may also qualify for NJ FamilyCare. Apply at 1-800-701-0710. Hospitals and substance use treatment providers that are approved for it can grant short-term presumptive eligibility. In SAMHSA’s survey, 299 New Jersey facilities offered a sliding fee scale.

How to vet a rehab program

Start with the license. Treatment programs in New Jersey are licensed by the New Jersey Department of Health under N.J.A.C. 8:111 (residential treatment and non-hospital medical detox) or N.J.A.C. 8:43K (outpatient, IOP, partial care, ambulatory detox and opioid treatment programs). Hospital detox and inpatient units operate under hospital licenses. Ask the program for its license type and confirm it in the NJSAMS Treatment Directory, run by the state Division of Mental Health and Addiction Services. Accreditation by the Joint Commission or CARF is a useful extra, not a substitute.

Then ask four questions on the first call:

1. Which levels of care do you offer, and how do you decide when I move between them?
2. Do you prescribe medication for opioid and alcohol use disorder, and will you continue what I take now?
3. Are you in network with my plan, and what will I owe, in writing, before admission?
4. What is arranged for the day I leave: the next program, a prescriber, a place to live?

Our guide to choosing a facility has the full list of ten questions.

Red flags, including patient brokering

Patient brokering means someone is paid to deliver you to a program. When insurance or a public program pays for the care, both New Jersey and federal law make it a crime. New Jersey’s runner law, N.J.S.A. 2C:21-22.1, makes it a third-degree crime to knowingly act as a “runner,” or to hire one. A runner is a person paid to bring a patient to a provider that bills insurance or a state or federal health program. The federal Eliminating Kickbacks in Recovery Act, 18 U.S.C. § 220, bars knowingly and willfully paying or receiving anything of value for referring a patient to a recovery home or a licensed non-hospital treatment facility. EKRA reaches private insurance as well as public programs.

End the call if you hear any of these:

• Someone offers you money, free travel, rent or insurance premiums to enroll.
• A treatment “recruiter” contacts you first by phone, text or social media.
• A helpline will not say which company is answering or which program it sends people to.
• The program will not tell you its license type, address or network status.
• You are pressed to decide within the hour, or promised a cure or a success rate.

If you think you were brokered, tell your insurer’s fraud unit and the program’s licensing agency.
