Comparing rehabs that accept Medicaid on Long Island starts with the 79 SAMHSA-listed facilities that take it, out of 83 total. The listings also show 16 that offer detox, 14 with residential beds, 24 with intensive outpatient programs, and 63 with general outpatient care. That range matters because the level of care you need shapes which programs are actually a fit, not just which ones take your coverage. A program can accept Medicaid and still have no opening in the service you need this week.
We are not a treatment provider and we do not diagnose anyone. Referral specialists tied to licensed treatment programs staff the helpline. Calling costs nothing, remains private, and binds you to nothing at all. Ask about Medicaid, private insurance, or self-pay, and it is completely fine to say you are unsure which level of care fits. An advisor can guide you through the SAMHSA listings and spell out what a Long Island rehab will probably ask when you get in touch.
Before you call a Medicaid rehab
- Have your Medicaid card or managed care plan information ready so the program can check benefits without delay.
- Ask whether the facility is licensed for the level of care you need, since Medicaid acceptance does not always mean every service is covered.
- If you drink heavily or use benzodiazepines, ask about medical supervision for withdrawal; these withdrawals can be dangerous and should not be managed alone.
- Ask about out-of-pocket costs even with Medicaid, including any copays or non-covered services, and request the answer in writing if you can.

Ask which levels of care the program is licensed for
A facility may accept Medicaid but still have limits on detox, residential, or outpatient slots. Of the 79 Medicaid-accepting facilities on Long Island, 16 offer detox, 14 offer residential, 24 offer intensive outpatient, and 63 offer outpatient. Ask specifically about the level you need.
- 3
Ask about medication-assisted treatment
Buprenorphine is one option for opioid use disorder, and 71 of the 79 Medicaid-accepting facilities list it. When you call, ask whether the program offers buprenorphine or other medications and whether Medicaid covers the visit. This is a medical decision, so discuss it with a clinician.

Ask what the first appointment looks like
When you do not know how risky withdrawal would be for you, ask if the program offers medical oversight. Stopping alcohol or benzodiazepines can be dangerous, so a program with detox or medical monitoring may be the safer place to begin. Ask what to bring and how quickly you can be seen.

What services are offered matters as much as how many facilities there are. Certain centers lean toward outpatient care, while others provide structured inpatient or detox services. If a particular level of care is what you need, ask about it outright instead of assuming every Medicaid-accepting facility runs the same programs. For detox or residential care on Long Island, check that the program’s Medicaid contract covers that level before you build plans around it. The helpline can help you weigh what is listed against what you truly need.

Does New York Medicaid cover inpatient rehab on Long Island?

A dual diagnosis program treats substance use together with a mental health condition like depression or anxiety, coordinated in a single plan. Some SAMHSA-listed facilities offer this kind of care, but ask them directly whether both services are available. If you carry a mental health diagnosis, tell the program at intake so they can match you with the right level of care. This site does not diagnose, so a licensed clinician should assess your needs.

In 2026, qualified health plans limit yearly out-of-pocket costs to $10,600 for self-only coverage and $21,200 for family coverage, but Medicaid operates under different cost-sharing rules. Before beginning, request a written estimate from the facility of what you would owe. The helpline has no cost and can help you prepare that question.

Detox may take place with medical oversight, and of the 79 Long Island facilities accepting Medicaid, 16 list detox services.
