NJ X-Waiver, IRTS, and MICA Programs Explained

New Jersey’s addiction treatment system includes several program types that are specific to the state or use terminology that can be confusing for individuals and families trying to navigate care. This page explains four NJ-specific program types: the former X-waiver system for buprenorphine prescribing (now superseded by federal law), Integrated Residential Treatment Services (IRTS), Mentally Ill Chemical Abuser (MICA) programs, and the partial care system.

Understanding what these programs are, who they serve, and how to access them is essential for anyone navigating NJ’s treatment landscape — particularly for individuals with co-occurring mental health and substance use disorders, who are served by multiple program types discussed here.

Key Takeaways

• The X-waiver for buprenorphine prescribing was eliminated by the federal MATE Act in late 2022 (effective 2023). Any DEA-registered prescriber with appropriate training can now prescribe buprenorphine.
• IRTS (Integrated Residential Treatment Services) programs are NJ DMHAS-funded residential facilities specifically for people with co-occurring mental health and substance use disorders.
• MICA (Mentally Ill Chemical Abuser) programs serve people with serious mental illness and substance use disorders. The term is older but still used in NJ program nomenclature.
• Partial care is NJ’s term for structured day programs that provide mental health and substance use services, functioning as a step between inpatient and standard outpatient care.

X-Waiver and Buprenorphine Access in NJ

What the X-Waiver Was

For more than two decades, prescribing buprenorphine (the active ingredient in Suboxone, Subutex, and Zubsolv) for opioid use disorder required a special federal waiver. This “X-waiver” — named for the “X” prefix added to the prescriber’s DEA number — was established by the Drug Addiction Treatment Act of 2000 (DATA 2000).

Under the X-waiver system:

• Physicians had to complete 8 hours of training to qualify.
• Nurse practitioners and physician assistants required 24 hours of training.
• Prescribers faced patient caps limiting how many patients they could treat with buprenorphine simultaneously (initially 30, later expanded to 100 and then 275).
• The waiver application was a separate process from standard DEA registration.

The X-waiver system was widely criticized for creating an unnecessary barrier to treatment. In a state like New Jersey, where opioid use disorder is prevalent across urban, suburban, and rural communities, the waiver requirement limited the number of prescribers and concentrated MAT access in specialized clinics rather than integrating it into primary care.

Current Prescribing Rules After the MATE Act

The Mainstreaming Addiction Treatment (MATE) Act, signed into law in late 2022 and effective in 2023, eliminated the X-waiver requirement. The key changes:

• No separate waiver needed: Any practitioner with a current DEA registration can now prescribe buprenorphine for opioid use disorder. No special waiver, no “X” number, no separate application.
• Training requirement: The MATE Act requires all DEA-registered prescribers to complete 8 hours of training on substance use disorders as part of their registration renewal. This is a one-time requirement that mainstreams SUD education across the medical profession.
• No patient caps: The caps on how many patients a prescriber can treat with buprenorphine have been eliminated.

What this means for NJ residents: In theory, any physician, nurse practitioner, or physician assistant in New Jersey can now prescribe buprenorphine. In practice, the transition is still ongoing. Many primary care providers have not yet integrated buprenorphine prescribing into their practice, particularly in rural areas. However, the elimination of the regulatory barrier has expanded access, particularly through:

• Federally Qualified Health Centers (FQHCs) that have added buprenorphine prescribing to their primary care services
• Emergency departments that initiate buprenorphine treatment during overdose or withdrawal presentations
• Telehealth MAT services that provide buprenorphine management for patients across the state

To find a buprenorphine prescriber in NJ, use the SAMHSA treatment locator at findtreatment.gov or call the NJ Addictions Hotline at 1-844-276-2777.

IRTS Programs in New Jersey

What IRTS Is

IRTS (Integrated Residential Treatment Services) is a residential treatment program model funded and regulated by the NJ Division of Mental Health and Addiction Services (DMHAS). IRTS programs are specifically designed for individuals with co-occurring mental health and substance use disorders — a population that requires integrated treatment addressing both conditions simultaneously.

IRTS programs provide:

• Residential housing: Clients live in a structured residential setting for the duration of the program, which typically lasts several months to a year or more depending on individual progress.
• Integrated treatment: Unlike programs that address mental health and addiction in separate tracks, IRTS programs deliver both services in a single integrated framework. Clinicians are trained to treat both conditions concurrently.
• Psychiatric services: IRTS programs provide psychiatric medication management, which is critical for individuals with serious mental illness (schizophrenia, bipolar disorder, major depressive disorder) who also have substance use disorders.
• Skill building and rehabilitation: Life skills training, vocational support, and community reintegration are core components.
• Transition planning: IRTS programs develop discharge plans that connect clients with ongoing outpatient services, housing, and community support.

Who Qualifies and How to Access

IRTS programs serve a specific population:

• Eligibility: Individuals must have both a diagnosed mental illness and a substance use disorder. The mental health condition must be of sufficient severity to warrant residential-level mental health care (typically serious mental illness).
• Referral pathway: Referrals to IRTS programs typically come through county mental health boards, screening centers, or inpatient psychiatric units. Self-referral may be possible in some cases, but the standard pathway involves a clinical referral.
• Funding: IRTS programs are primarily funded through DMHAS contracts and serve individuals who are Medicaid-eligible or uninsured. NJ FamilyCare covers IRTS services.
• Availability: IRTS programs exist throughout New Jersey but capacity is limited. Waitlists are common, particularly in counties with high demand.

To inquire about IRTS program availability, contact the county mental health board in your area or call the NJ Addictions Hotline at 1-844-276-2777.

MICA Programs in NJ

Mentally Ill Chemical Abuser Programs

MICA stands for Mentally Ill Chemical Abuser — an older term that is still used in New Jersey’s program nomenclature and clinical shorthand, even though it has largely been replaced in national discourse by the term “co-occurring disorders” or “dual diagnosis.”

MICA programs in NJ serve individuals who have both a serious mental illness and a substance use disorder. These programs differ from standard addiction treatment in several ways:

• Psychiatric expertise: MICA programs are staffed with clinicians trained to manage serious mental illness (psychotic disorders, severe mood disorders, personality disorders) alongside substance use treatment.
• Medication management: Active psychiatric medication management is a core component, not an ancillary service.
• Modified treatment approaches: Standard addiction treatment modalities (such as 12-step-based programming) may be modified for individuals whose psychiatric conditions affect their ability to participate in traditional treatment formats.
• Longer treatment timelines: Individuals with co-occurring serious mental illness and substance use disorders often require longer treatment episodes and more gradual transitions to community-based care.

Where to Find MICA Services

MICA programs operate at various levels of care in New Jersey:

• Residential MICA programs: Provide 24-hour structured care for individuals who need residential-level support for both conditions. These programs often overlap with or complement IRTS programs.
• Outpatient MICA programs: Provide specialized outpatient treatment that integrates mental health and substance use services. These may operate as part of community mental health centers or hospital-affiliated behavioral health departments.
• MICA-capable vs. MICA-enhanced: In NJ’s treatment system, “MICA-capable” indicates that a program can serve individuals with co-occurring disorders but does not specialize in them. “MICA-enhanced” indicates a specialized program with dedicated staff and programming for the co-occurring population.

Access to MICA services is typically coordinated through county mental health boards, which maintain referral networks and knowledge of available program slots. NJ 2-1-1 and the NJ Addictions Hotline can also help connect individuals with MICA services.

Partial Care Programs in NJ

What Partial Care Means in NJ

Partial care is NJ’s term for structured day treatment programs that provide mental health and/or substance use services in a group setting. Partial care occupies a middle ground between inpatient/residential treatment and standard outpatient care, functioning similarly to what other states call partial hospitalization programs (PHPs) or structured day programs.

Key characteristics of NJ partial care programs:

• Schedule: Partial care typically operates during daytime hours, with clients attending structured programming for several hours per day, multiple days per week.
• Services provided: Group therapy, individual counseling, psychoeducation, medication management, case management, and skill-building activities.
• Level of care: Partial care is appropriate for individuals who need more structure and intensity than weekly outpatient sessions but do not require 24-hour residential care.
• Integration with community living: Clients in partial care live at home or in supportive housing and attend the program during the day, maintaining connections to their community.

NJ’s partial care system is part of the DMHAS continuum of services and is funded through a combination of Medicaid (NJ FamilyCare), state funding, and county contracts.

Finding Partial Care Programs by County

Partial care programs are distributed across New Jersey’s counties, though availability varies by region. To find a partial care program:

• Contact the county mental health board: Each NJ county’s mental health board maintains information on locally available partial care programs and can assist with referrals.
• NJ 2-1-1: Can provide county-specific partial care program information.
• DMHAS provider directory: The state’s licensed provider directory lists partial care programs by county.
• Managed care organization (MCO): For NJ FamilyCare enrollees, the MCO assigned to the individual’s plan can provide referrals to in-network partial care programs.

Middlesex County, which is frequently searched for partial care programs, has multiple options through its county mental health system and through programs operated by organizations like Rutgers University Behavioral Health Care. Contact the Middlesex County Office of Health Services or NJ 2-1-1 for current program information.

What a typical partial care schedule looks like:

• Monday through Friday, approximately 9:00 AM to 2:00 or 3:00 PM
• Morning group therapy sessions
• Psychoeducation or skill-building workshops
• Lunch (sometimes provided by the program)
• Afternoon individual sessions or specialized groups
• Weekly medication management appointments with a psychiatrist or nurse practitioner

The duration of participation in partial care varies. Some individuals attend for a few months as a step-down from residential treatment, while others participate for longer periods as their primary level of ongoing care.
