Dual Diagnosis Treatment in New Jersey: How Integrated Care Works

What counts as a dual diagnosis

A dual diagnosis is a substance use disorder and a mental health disorder in the same person at the same time. SAMHSA’s term is co-occurring disorders, and it covers any combination: alcohol use disorder with depression, opioid use disorder with PTSD, stimulant use with bipolar disorder, cannabis use with anxiety. No pairing is special. What matters is that both are present, and each can make the other harder to treat.

It is not rare. In SAMHSA’s 2025 National Survey on Drug Use and Health, about 18.5 million U.S. adults had both a mental illness and a substance use disorder in the past year. That is about two in five of the 42.7 million adults with a substance use disorder.

Most people with both get treated for one

The same survey asked what treatment those 18.5 million adults received:

About one in eight got care for both conditions. Most of the people who got any care got mental health care alone.

That gap is why the yes-or-no question does not help. Ask a program “do you treat dual diagnosis?” and most will say yes. Ask how.

What integrated treatment means

Integrated treatment means one team screens for both conditions, writes one treatment plan, and treats both at the same time. The National Institute on Drug Abuse says the high overlap between substance use and mental disorders calls for an integrated approach that identifies and treats them at the same time. Treatment can include medications, psychosocial therapy, or both.

It helps to know the two arrangements that are not integrated, because a program may describe either one as dual diagnosis care:

• Sequential care: “Get sober first, then we will look at the depression.” Or the reverse.
• Parallel care: an addiction counselor in one building and a psychiatrist in another, with no shared plan and often no contact between them.
• Integrated care: both conditions, one plan, one team that talks to itself.

One detail changes how you should judge a program. Waiting for sobriety before treating mental health is not required. The National Institute on Alcohol Abuse and Alcoholism tells clinicians they do not need to wait until a patient is sober to start antidepressants when there is evidence of need, and that both conditions can be treated at the same time. The same source notes that quitting drinking on its own often improves co-occurring mental health symptoms, which is one reason a good program keeps reassessing the mental health diagnosis as treatment goes on instead of locking it in on day one.

Medications on both sides

For opioid use disorder, NIDA notes that effective medications exist. Our medication guide covers buprenorphine, methadone and naltrexone. A dual diagnosis program should continue those medications, not ask you to stop them to get mental health care.

The prescribing has to be coordinated. SAMHSA warns that combining medications used to treat substance use disorders with anxiety medications such as benzodiazepines (Xanax, Valium, Klonopin) can have serious adverse effects. When two prescribers who do not talk to each other each write a script, this is where it goes wrong. Ask who holds the whole medication list.

Co-occurring capable and co-occurring enhanced

The ASAM Criteria, the placement standard New Jersey uses for addiction care, sorts programs by how much mental health care they can carry. The fourth edition expects every program to be co-occurring capable: able to manage mild to moderate mental health symptoms during routine addiction treatment and to coordinate with outside providers when needed. Programs that routinely serve people with more severe or complex mental health conditions are co-occurring enhanced.

Ask the program which one it is at the level of care you are being offered. A program that answers “we are co-occurring enhanced at residential, capable at IOP” knows its own limits, which is a good sign. A program that does not recognize the terms is telling you something too.

Levels of care, and the New Jersey term “Partial Care”

Dual diagnosis care happens at every level, from a hospital unit to a weekly appointment. The names in New Jersey differ slightly from the national ones, which causes real confusion on the phone.

“Partial Care” is the term to know. In New Jersey’s rules, partial care is a structured day program: you attend during the day and go home at night. Mental health partial care is built for adults with a serious mental illness, and the state’s program standards call for a psychiatric assessment, counseling and therapy, psychoeducation, and rehabilitative skills work on things like daily living, housing and work. Ask each program how many hours a day and days a week it runs. NJ FamilyCare also lists a separate substance use disorder partial care service. So when a program says “partial care,” ask which kind: mental health, substance use, or both.

How New Jersey licenses these programs

The New Jersey Department of Health licenses both sides. Since April 6, 2026, outpatient programs, including outpatient and intensive outpatient mental health and substance use treatment, partial care, outpatient detox and opioid treatment programs, are licensed under N.J.A.C. 8:43K, the state’s rules for outpatient and integrated care facilities. Residential substance use treatment and freestanding medical detox are licensed under N.J.A.C. 8:111, and hospital units run under the hospital’s own license. The program standards for adult outpatient, substance use intensive outpatient, partial care and opioid treatment programs, the rules for what happens inside them, sit in a separate chapter from the Division of Mental Health and Addiction Services that took effect the same day, N.J.A.C. 10:36.

The practical point: a license covers specific services. One 8:43K license can cover mental health services, substance use services or both, so ask which services the program is licensed to provide at the location you would attend. For the substance use side, you can check the state’s directory of licensed substance use treatment providers.

Paying for it

NJ FamilyCare or no insurance

Start with the IME Addictions Access Center at 1-844-276-2777, which screens callers and refers them to treatment, 24/7. It authorizes residential detox and rehab for most NJ FamilyCare members, and it screens uninsured callers for state-funded treatment.

Since January 1, 2025, your NJ FamilyCare health plan manages most outpatient behavioral health care itself. The state’s behavioral health integration FAQ lists mental health partial care, mental health partial hospitalization, mental health outpatient care, and substance use counseling, intensive outpatient, partial care and outpatient detox among the services the plans now cover. Residential substance use treatment, residential detox and opioid treatment programs are still paid by the state directly for now. For an integrated outpatient program, your plan’s member services line is a real door in, and you can ask the plan for a care manager. Our NJ FamilyCare guide lists each plan’s number.

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.

Read that rule for what it covers. It comes from P.L.2017, c.28, a law about substance use disorder treatment. The mental health half of a dual diagnosis admission is not covered by that law, and the plan may still require prior authorization for it. Federal parity law generally prevents plans that cover mental health care from limiting it more than medical and surgical care, but that is not the same as no prior authorization. Ask the plan about both halves before the first day. Our parity guide explains how to tell whether your plan is fully insured or self-funded.

How to find an integrated program in New Jersey

1. Search FindTreatment.gov with the right filters. SAMHSA’s FindTreatment.gov lets you filter by what a program reports offering. Enter your town, then under Special Programs/Groups Offered choose “Clients with co-occurring mental and substance use disorders.” For serious mental illness, the Type of Care filter has “Treatment for co-occurring disorders plus serious mental illness (SMI) in adults.” Also useful: “Comprehensive mental health assessment” and “Medication for mental disorders.” These are self-reported, so confirm by phone.
2. Call a state line. For the substance use side, ReachNJ (1-844-732-2465) and, for NJ FamilyCare or uninsured callers, the IME (1-844-276-2777) answer 24/7. For the mental health side, NJ MentalHealthCares, the information and referral line run by the Mental Health Association in New Jersey, is at 1-866-202-HELP (4357), 8 a.m. to 8 p.m. daily. It is not a crisis line.
3. Use our lists for the detox step. If withdrawal comes first, our directory of New Jersey detox programs lists licensed withdrawal management programs alphabetically, and our guide to rehab in New Jersey covers the step after.
4. Call two or three programs and ask the questions below. The answers sort them faster than any website.

Questions to ask a dual diagnosis program

• Do you screen every client for both mental health and substance use conditions at intake?
• Is there one treatment plan for both, written by one team?
• Is a psychiatrist or psychiatric nurse practitioner on staff, and how often will I see them?
• Are you co-occurring capable or co-occurring enhanced at this level of care?
• Which licenses do you hold, and which one covers the service I would be using?
• Will you continue my buprenorphine, methadone or naltrexone? Will you continue my psychiatric medications?
• Who keeps my full medication list, and how do you handle benzodiazepines?
• Which therapies do you use for trauma, depression or anxiety, and are the clinicians licensed in mental health?
• If you call it Partial Care, is it mental health partial care, substance use partial care, or both?
• What happens at discharge: who is my next prescriber, and is the next appointment booked before I leave?

A program that answers all ten with specifics is probably doing the work. A string of “yes, we do that” answers tells you less. Our facility checklist has the general questions, and the relapse prevention worksheet is a good thing to fill in with the team once you are in.

Where our publisher fits

DetoxNJ is published by Periscope Behavioral Health, which operates or holds an ownership interest in Emerald Wellness, an outpatient mental health program in Kendall Park, Middlesex County. Emerald’s programs include mental health Partial Care, intensive outpatient and a perinatal intensive outpatient program.

Emerald does not provide detox or addiction treatment. It is not a dual diagnosis program in the sense this page describes, and we do not suggest it for anyone whose main need is substance use treatment. If you are looking for integrated care for both conditions, use the filters and questions above, and judge every program, including any connected to us, by the same answers.
