What OASAS Certification Means When Choosing a New York Treatment Center

If a treatment program in New York is legitimate, it holds an operating certificate from the New York State Office of Addiction Services and Supports. You can confirm that yourself, free, in about two minutes, using a public state database — and you should, before you give any program your insurance details.

But certification is a floor, not a recommendation. It tells you a program meets the state’s minimum operating standards and is accountable to a regulator. It does not tell you the program is good, that it suits your situation, or that its outcomes are strong. This guide covers both halves: how to verify certification properly, and what certification genuinely does and does not guarantee.

A note on who is writing this. The Recover is a referral network, not a treatment provider. We benefit when people enter treatment through programs in our network, and you should weigh that. Everything below is checkable against state sources we link to directly — including checks you can run on us and on any program we might suggest.

What OASAS certification actually is

The Office of Addiction Services and Supports regulates addiction treatment in New York. A program cannot lawfully provide certified substance use treatment in the state without holding an operating certificate from the agency, and that certificate is specific to the services the program is authorised to deliver.

Getting certified is not a formality. A program must demonstrate appropriate clinical staffing, physical premises meeting state standards, written policies covering admission, treatment planning, discharge and patient rights, an incident management program, and adherence to service standards requiring care to be person-centred, strength-based and trauma-informed. Certification is reviewed and renewed rather than granted permanently, and it can be restricted or revoked.

The detail almost nobody explains

Certification is not a single badge. A program holds a base operating certificate under Part 810, then separate authorisation for each type of service it provides. The regulation number tells you what the program can legally deliver — and a program certified only for outpatient services cannot lawfully run a residential bed, no matter what its website implies.

Regulation	What it authorises	What it means for you
Part 810	The base operating certificate every certified provider must hold	Without this, the program is not certified at all
Part 816	Withdrawal and stabilisation services	Medically supervised detox and withdrawal management
Part 820	Residential services, with separate designations for stabilisation, rehabilitation and reintegration	Live-in treatment. A program must hold this to provide residential care lawfully
Part 822	Outpatient programs, including opioid treatment programs	Outpatient, IOP and PHP-level care, plus methadone and buprenorphine programs
Part 815	Patient rights in certified programs	The rights the program owes you once you are admitted
Part 836	Incident reporting obligations	How abuse, neglect and serious incidents must be reported and investigated

This matters practically. If a program markets itself as residential but the state directory lists it under Part 822, you are looking at an outpatient provider describing itself as something else. That is a reason to ask a direct question, and the answer will tell you a lot. Our guides to residential rehab, IOP and medical detox explain what each level of care actually involves.

How to check a program yourself

This takes about two minutes and requires nothing but the program name.

1. Open the state’s Provider and Program Search, the official OASAS directory of certified programs.
2. Search by program name, or browse by county and service type if you are exploring options.
3. Check the program appears at all. If a New York facility is not listed, that is the single most important finding on this page. Ask them directly why.
4. Read the service type. This is where the Part number appears, and it tells you what the program is authorised to provide.
5. Confirm the address matches the location where you would actually receive care. Programs with several sites hold certification per site, not per company.
6. Note the five-digit provider number. Quote it when you call your insurer — it removes any ambiguity about which entity you mean.
7. Note the program director and their credentials. Directors are listed with qualifications such as CASAC, and a program with no named clinical leadership in the state record is worth a question.

If a program tells you certification is pending, ask when the application was filed and which Part it covers. Pending is not certified, and while applications are legitimate, you are entitled to know you would be entering a program the state has not yet signed off.

What certification guarantees — and what it does not

Being clear about this is more useful than overselling it.

What it does tell you

• The program meets the state’s minimum standards for staffing, premises, policies and clinical practice.
• It is subject to inspection, and its certificate can be restricted or withdrawn.
• Staff delivering clinical care hold recognised credentials — CASAC, licensed clinical social worker, mental health counsellor, marriage and family therapist, psychologist, psychiatrist, or creative arts therapist, among others.
• You are covered by the patient rights provisions in Part 815 and the incident reporting obligations in Part 836.
• It sits within the category New York-regulated insurers are required to cover.

What it does not tell you

• Whether outcomes are good. New York does not publish comparative outcome data by program, so certification carries no performance signal.
• Whether the program suits your specific situation — co-occurring mental health conditions, a particular substance, adolescent care, or treatment alongside a partner.
• What it costs you, or whether it is in your insurance network. Those are entirely separate questions.
• Whether the clinical approach matches what the evidence supports for your condition. A program can be certified and still, for instance, discourage medication for opioid use disorder — which runs against the clinical consensus.

Treat certification as a gate you pass through, then ask everything else on the other side of it. Our guide to medication-assisted treatment for opioid addiction is a reasonable place to start on the clinical questions.

Certification, licensing and accreditation are three different things

These get used interchangeably in marketing, and they are not the same.

• Certification is the state authorisation to operate. In New York that is OASAS, and it is mandatory. Without it a program cannot lawfully provide certified treatment.
• Licensing usually refers to the individual clinicians, who hold their own credentials from the State Education Department or OASAS. A certified program employs licensed people; the two are related but distinct.
• Accreditation comes from independent non-government bodies — most commonly the Joint Commission or CARF. It is voluntary, it costs the program money, and it signals a willingness to be examined beyond the legal minimum. It is not a substitute for certification.

Accreditation matters more than usual if you are considering treatment outside New York, because New York regulations allow insurers to limit out-of-state coverage to programs accredited by the Joint Commission as chemical dependence treatment programs and appropriately licensed in their own state. Our guide to out-of-network rehab in New York covers how that interacts with your benefits.

Why certification affects what your insurance pays

This is the connection most people miss. New York law requires plans to cover substance use disorder treatment, but it also permits coverage to be limited to facilities licensed, certified or otherwise authorised by OASAS. In practice, a non-certified New York program may not be covered at all, regardless of how good it looks.

The protections New York layers on top are also tied to certification. The prohibition on prior authorisation for outpatient substance use treatment applies at in-network OASAS-certified facilities specifically. Choosing a non-certified program does not just risk your claim — it forfeits a protection the state gave you.

Our guide to whether insurance has to cover rehab in New York sets out the full set of requirements, and how to check your benefits before you call walks through confirming your own coverage.

The rights you have inside a certified program

Once you are admitted to an OASAS-certified program, your rights are protected under New York Mental Hygiene Law. The state publishes these as patient rights and protections, and two things in particular are worth knowing before you need them.

First, if something is wrong, you raise it with program staff — and no punitive action may be taken against anyone in treatment for voicing a concern. That protection exists precisely because the power imbalance in a residential setting is obvious to everyone involved.

Second, if the matter is serious or raising it internally has not worked, you can go outside the program:

• OASAS Patient Advocacy, for complaints about a program: 1-800-553-5790
• The New York State Justice Center, for abuse or neglect: 1-855-373-2122
• OASAS Credentialing, for a complaint about a specific counsellor’s conduct.

Certified programs also operate under mandatory incident reporting rules. Staff are legally required to report suspected abuse, neglect and other serious incidents immediately, and programs must maintain incident management procedures reviewed by the state. That machinery only exists in certified programs — which is a substantive reason to prefer one, separate from anything about insurance.

Questions worth asking once certification checks out

Certification gets a program onto your list. These questions decide whether it belongs there.

8. Which Part are you certified under for the service I would receive? The answer should match the state directory.
9. Are you accredited by the Joint Commission or CARF? Voluntary, but a useful signal.
10. Do you offer medication for opioid or alcohol use disorder on site? A programme that discourages it should be able to explain why in clinical terms.
11. How do you handle co-occurring mental health conditions? Ask whether psychiatry is on staff or referred out. See our guide to dual diagnosis treatment.
12. What are your clinical staffing ratios, and who provides individual therapy? Group-only programming is common and not necessarily wrong, but you should know.
13. What happens when I step down? Ask about the transition to IOP, sober living or ongoing outpatient care.
14. Are you in-network for my plan? “We accept your insurance” is not the same answer.

Warning signs

Some of these are illegal, some merely tell you what kind of operation you are dealing with.

• The program does not appear in the OASAS directory and cannot explain why.
• Offers of free travel, free rent or cash. Patient brokering is illegal in several states and is a strong signal to stop.
• A guarantee of coverage or a promise you will pay nothing, before any claim has been processed.
• An offer to waive your deductible or copayment as an inducement to admit.
• Pressure to admit today with no clinical reason given. Withdrawal risk is a real clinical urgency; sales urgency is not the same thing.
• Refusal to put network status or cost in writing.
• Success rate claims with no methodology behind them. No credible program publishes an unqualified recovery percentage.

If you are looking outside New York

OASAS certification only applies within New York. For an out-of-state program, check the equivalent state licensing body, check Joint Commission or CARF accreditation, and confirm with your insurer that the facility meets its out-of-state requirements. The federal FindTreatment.gov locator covers all states and lets you filter by service type and payment options. Our guide to addiction treatment for New Yorkers seeking care in California covers how coverage works when you travel for treatment.

Frequently asked questions

What does OASAS certified mean?

It means the New York State Office of Addiction Services and Supports has issued the program an operating certificate, confirming it meets state standards for staffing, premises, clinical policies and patient rights, and that it is subject to state oversight and inspection. Certification is specific to the services a program is authorised to provide.

How do I check if a rehab is OASAS certified?

Use the OASAS Provider and Program Search, the state’s public directory. Search by program name or browse by county and service type. Confirm the program is listed, that the address matches where you would receive care, and that the service type covers the level of care you need.

Is OASAS certification required for rehab in New York?

Yes, for programs providing certified substance use treatment in New York. A program cannot lawfully provide these services without an operating certificate. Certification can also determine whether your insurance will pay, since New York permits plans to limit coverage to OASAS-authorised facilities.

Does OASAS certification mean a program is good?

No. Certification confirms minimum standards and state accountability. It carries no information about outcomes, clinical quality or whether a program suits your situation. Treat it as a gate to pass through, then ask about staffing, medication policy, co-occurring conditions and aftercare.

What is the difference between Part 820 and Part 822?

Part 820 authorises residential services, with separate designations for stabilisation, rehabilitation and reintegration. Part 822 authorises outpatient programs, including opioid treatment programs. A program certified only under Part 822 cannot lawfully provide residential treatment.

What if a treatment center is not OASAS certified?

Ask directly why. There are legitimate explanations — a program may be a sober living residence rather than a treatment provider, or an out-of-state facility. But a New York program presenting itself as addiction treatment while absent from the state directory is a serious concern, and your insurance may not cover it.

Does OASAS certification affect my insurance coverage?

Yes, significantly. New York permits plans to limit coverage to OASAS-licensed or certified facilities, and the state prohibition on prior authorisation for outpatient substance use treatment applies specifically at in-network OASAS-certified facilities.

Who do I contact if something goes wrong at a certified program?

Raise it with program staff first, and no punitive action may be taken against you for doing so. For more serious grievances, contact OASAS Patient Advocacy on 1-800-553-5790, or the New York State Justice Center on 1-855-373-2122 for abuse or neglect.

Is accreditation the same as certification?

No. Certification is mandatory state authorisation from OASAS. Accreditation from the Joint Commission or CARF is voluntary, independent and additional. Accreditation matters particularly for out-of-state programs, since New York insurers may require it for out-of-state coverage.

How do I check credentials of the staff?

The state directory lists the program director with their credentials. For clinical staff, ask what proportion hold CASAC credentials or clinical licences, who provides individual therapy, and whether psychiatry is available on site or by referral.
