Medicaid and Addiction Treatment in New York

New York Medicaid covers addiction treatment at every level of care — withdrawal management, inpatient rehabilitation, residential treatment, outpatient programs, methadone and buprenorphine. Not a limited version. The full continuum.

And for substance use disorder services specifically, New York exempts clinic visits from copays entirely. For most people on Medicaid in this state, a course of addiction treatment costs nothing out of pocket. Where any copay applies at all, total Medicaid copays are capped at $200 for the whole year.

That is a different financial picture than most people expect, and it is the reason this page exists. The barriers to treatment on New York Medicaid are almost never the coverage itself. They are not knowing you qualify, not knowing treatment already received can still be paid for, and not knowing which programs take the plan. This guide handles all three.

The Recover is a referral network of licensed, independent treatment providers — not an insurance company, a government agency, or a treatment facility. We help New Yorkers find programs that match their coverage. For how coverage works across all carriers, see our insurance and rehab guide.

What New York Medicaid Covers for Addiction Treatment

New York funds a full continuum of addiction services through programs certified by the Office of Addiction Services and Supports. Medicaid pays for care at each level:

Level of care	What it is
Medically managed withdrawal	Hospital-based detox with 24-hour medical management for the most severe withdrawal risk
Medically supervised withdrawal	Inpatient or outpatient detox with clinical supervision, for moderate withdrawal risk
Inpatient rehabilitation	Structured 24-hour treatment following or in place of detox
Residential services	Stabilization, rehabilitation, and reintegration residential programs, plus youth residential
Outpatient clinic treatment	Individual and group therapy, assessment, medication management
Outpatient rehabilitation	More intensive structured outpatient programming
Opioid treatment programs	Methadone maintenance, dosed daily at a certified OTP
Medication-assisted treatment	Buprenorphine and naltrexone, prescribed and filled through the pharmacy benefit
Youth programs	Outpatient and residential services designed for adolescents

Two points of comparison are worth making, because they are where New York is genuinely unusual.

Residential treatment is covered. That sounds obvious and it is not. Residential substance use disorder services are not covered under Medicare Advantage plans in New York, and many states cover residential care thinly or not at all under Medicaid. New York covers it. If you are choosing between Medicaid and a Medicare Advantage plan and residential treatment is on the table, this difference is decisive.

There is no lifetime cap on treatment episodes. Relapse is part of the clinical picture for a chronic condition, and New York Medicaid does not cut you off after a set number of admissions. Continued coverage depends on documented clinical need, reviewed against the state level-of-care tool — not on a counter.

For what each level of care involves clinically, see medical detox, residential rehab, partial hospitalization, and intensive outpatient. If a mental health condition is part of the picture, dual diagnosis treatment is covered as well — and New York has a Medicaid plan built specifically for that combination, covered further down.

What It Costs: In Most Cases, Nothing

New York Medicaid charges small copays for some services, and exempts others outright. Substance use disorder treatment sits in the exempt column. Under the state’s Medicaid co-payment policy, visits to alcohol and substance abuse clinics and to methadone clinics carry no copay. Mental health clinic visits are likewise exempt, as are psychotropic medications.

Beyond that:

• Clinic and outpatient visits carry a $3 copay in fee-for-service Medicaid and $0 in managed care — and SUD clinic visits are exempt regardless.
• All Medicaid copays combined are capped at $200 per year, with a $50 quarterly ceiling. The copay year runs April 1 to March 31.
• Certain populations are exempt from copays entirely, including anyone under 21, pregnant members through 60 days postpartum, and members with income below 100% of the federal poverty level.
• There are no premiums for Medicaid, and no deductible to meet before coverage begins.

The practical consequence is worth stating plainly, because it changes decisions: on New York Medicaid, cost is not the reason to delay treatment. A 28-day inpatient rehabilitation stay and months of outpatient care afterward will, in the ordinary case, cost you nothing. Compare that with a commercial high-deductible plan where the same course of care can run into five figures before the deductible is satisfied.

Do You Qualify? New York Medicaid Income Limits

New York expanded Medicaid, which means single adults with no children qualify on income alone — no disability, no dependents, no other qualifying category required. The threshold for most adults aged 19 to 64 is 138% of the federal poverty level. Current figures published by the New York State Department of Health:

Household size	Monthly income limit	Annual income limit
One person	$1,836	$22,025
Two people	$2,489	$29,864

Some things that commonly surprise people about how this is calculated:

• Income is counted using modified adjusted gross income, which is close to what appears on your tax return — not gross wages before adjustments.
• There is no asset or resource test for this group. Savings, a car, and a bank balance do not disqualify an adult applying under the MAGI rules.
• Income is assessed on a current basis. Someone who has recently lost a job, or whose income has dropped, may qualify now even if last year’s return says otherwise.
• Different thresholds apply to other groups: 155% FPL for 19- and 20-year-olds living alone, 138% for parents and caretaker relatives, 154% for children 1 to 18, and 223% for pregnant members and infants.

If your income runs above the Medicaid line, the Essential Plan is the next tier — a $0-premium, no-deductible plan that also covers substance use disorder treatment. Nobody in New York is left with no low-cost option because they earn slightly too much for Medicaid.

Treatment You Already Received May Still Be Covered

This is the most valuable thing on this page for anyone holding a bill, and almost nobody knows it. New York Medicaid has a retroactive eligibility period of up to three months before the month you apply. Coverage begins on the first day of the third month preceding your application month.

Apply on April 30, and coverage can reach back to January 1. If you were treated in February with no insurance and are now carrying the bill, that bill may be payable by Medicaid.

The condition is simple: you have to report that you had paid or unpaid medical bills during that lookback window. When you do, eligibility for that period has to be determined. It is not automatic — you have to raise it.

So if you or a family member went through detox, an emergency department visit, or a treatment admission in the last ninety days while uninsured, say so on the application. And if you already paid out of pocket during that window, ask about reimbursement of paid medical bills rather than assuming the money is gone.

How to Apply, and How Long It Takes

Where you apply depends on which group you fall into. The New York State Department of Health sets the routes:

Adults 19 to 64 who do not have Medicare

Apply through NY State of Health, the state marketplace, at nystateofhealth.ny.gov or by phone at (855) 355-5777 (TTY 1-800-662-1220). This is the path for most people seeking addiction treatment coverage. Free enrollment assistors are available and are worth using — they know which documents actually hold things up.

People who are blind or disabled, SSI recipients, or seeking long-term care

Apply through your Local Department of Social Services. In New York City that is the Human Resources Administration, at (718) 557-1399 or (888) 692-6116.

General questions

The statewide Medicaid Helpline is (800) 541-2831.

What to have ready

Social Security number, proof of citizenship or immigration status, proof of age, four weeks of recent pay stubs if employed, proof of any other income, and proof of residence such as a rent receipt or mortgage statement.

Processing time

Standard applications are processed within 45 days. Applications for pregnant members and children are processed within 30 days. Applications requiring a disability determination can take up to 90 days.

Forty-five days is a long time when someone needs treatment this week. Two things shorten that in practice: the retroactive rule above means care received during the wait can still be covered once the application is approved, and many hospitals and OASAS-certified programs have staff who can screen for presumptive eligibility or help file the application on the spot. Ask the program before assuming you have to wait for a card.

Managed Care, HARP, and Which One You Want

Nearly everyone on New York Medicaid is enrolled in a managed care plan rather than fee-for-service. For addiction treatment there are two versions of that, and the difference matters.

Mainstream Medicaid managed care

The standard arrangement. Your plan covers physical and behavioral health, including the full SUD continuum described above.

HARP — Health and Recovery Plans

A HARP is a Medicaid managed care product built for adults with significant behavioral health needs, including serious mental illness and substance use disorders. Every HARP enrollee gets Health Home care management, and eligible members get an enhanced package of Behavioral Health Home and Community Based Services that mainstream plans do not cover.

Those BH HCBS services are the point. They cover the things that determine whether recovery holds after treatment ends:

• Employment support and job placement
• Help finding and keeping housing
• Peer support from people with lived recovery experience
• Independent living skills training
• Stress management and crisis prevention planning
• Education support

Eligibility is determined through an assessment conducted by a Health Home care manager — the New York State Eligibility Assessment, followed by a full Community Mental Health Assessment and a person-centered plan of care if you qualify. HIV Special Needs Plan members who meet the criteria can access HARP benefits while staying in their current plan.

If addiction is happening alongside unstable housing, unemployment, or a co-occurring mental health condition, ask your plan or your care manager directly whether you are HARP-eligible. It is not something that reliably gets offered — it usually gets requested.

The Protections That Come With New York Medicaid

New York restricts what plans can do to substance use disorder authorizations more tightly than almost any state, and these protections apply to Medicaid managed care plans as well as commercial ones.

• No preauthorization for inpatient SUD treatment at an OASAS-certified facility in the plan’s network, per the Department of Financial Services. Also none for outpatient SUD treatment at a licensed facility, or for SUD medications.
• No medical-necessity review during the first 28 days of inpatient treatment, provided the facility notifies your plan of the admission and treatment plan within two business days and performs daily clinical review.
• No concurrent review during the first four weeks of outpatient treatment, up to 28 visits, under the same notification conditions.
• Plans must use LOCADTR 3.0, the state level-of-care tool, or an alternative approved by OASAS — not proprietary internal criteria.
• Clinical reviewers making SUD determinations must have specialized training and experience in substance use disorder treatment.

These are the rules that decide whether a stay gets cut short. Prior authorization for detox in New York covers the mechanics, and OASAS-certified treatment in New York explains how to confirm a program’s certification — which is what most of these protections hinge on.

Medicaid Covers the Ride, Too

Transportation is an underrated reason treatment fails, particularly for opioid treatment programs that require daily dosing. New York Medicaid covers non-emergency medical transportation, managed statewide by Medical Answering Services.

• Covered modes include public transit fare, taxi and livery, ambulette, ambulance, and mileage reimbursement if someone drives you.
• Arrange trips at least 72 hours in advance through medanswering.com or by phone.
• Downstate: (844) 666-6270. Upstate: (866) 932-7740.
• If transportation is denied or does not show, complaints go to Medical Answering Services directly, or to the Department of Health at medtrans@health.ny.gov or (518) 473-2160.

For someone in a methadone program without a car, this benefit is the difference between a treatment plan that works and one that collapses in the third week. Set it up before the first appointment, not after a missed dose.

How Medications Are Covered: NYRx

Since April 2023, pharmacy benefits for members in mainstream managed care, HARPs, and HIV Special Needs Plans are handled by NYRx, the state Medicaid drug program, rather than by the individual health plans. Members in Managed Long-Term Care, the Essential Plan, and Child Health Plus were not affected by that change.

What this means in practice: your health plan card governs your medical care, but your prescriptions run through NYRx and its statewide formulary. Buprenorphine and naltrexone are filled at a pharmacy under this benefit. Methadone for opioid use disorder is different — it is dispensed at a certified opioid treatment program rather than a retail pharmacy, and is covered as a treatment service rather than a pharmacy claim.

If a pharmacy tells you a medication is not covered, that is a NYRx question, not a plan question. NYRx can be reached at (518) 486-3209 or NYRx@health.ny.gov.

Finding a Program That Takes Medicaid

Coverage is only half of it. The other half is finding a program with an opening.

• New York runs a public treatment availability tool at findaddictiontreatment.ny.gov, which lets you search OASAS-certified programs by location and level of care.
• The OASAS provider and program search covers certified outpatient and bedded programs statewide.
• The OASAS HOPEline is staffed 24 hours a day at (877) 846-7369 for treatment access questions and referrals.
• Your Medicaid plan’s member services line can give you in-network SUD programs — this is the fastest route to a list that is actually covered.

Four questions worth asking every program you call:

1. Are you OASAS-certified, and are you in network for my specific Medicaid plan? Not “do you take Medicaid” — which plan.
2. What is your current wait for the level of care I need, and do you keep an interim or waitlist support option?
3. Will you handle the two-business-day notification to my plan after admission?
4. Do you provide medication-assisted treatment on site, or coordinate it, if that is part of my plan of care?

If Your Medicaid Plan Denies Treatment

Medicaid denials follow a different track from commercial ones, and one deadline here is much shorter than it appears.

• You generally have 60 days from the plan’s initial adverse determination to file a plan appeal.
• But to keep services running while the appeal is decided — aid continuing — you must file within 10 days of the notice or the effective date of the action, whichever is later. Ten days, not sixty. This is the single most common way people lose treatment they were entitled to keep.
• Plan appeals are decided within 30 calendar days standard, or 72 hours expedited.
• After a final adverse determination you have at least 120 days to request a State Fair Hearing, and 10 days from the plan’s written decision to keep aid continuing through that hearing.
• Ask your plan for the medical necessity criteria applied to your case. Behavioral health administrators are required to provide them on request.

If treatment is underway and inpatient, move immediately — the protections described in what to do when a New York insurer denies rehab apply, and the window is measured in hours. Free help is available from CHAMP, the state behavioral health ombudsman, at (888) 614-5400.

Five Things People Get Wrong About Medicaid and Rehab

“Medicaid only gets you into low-quality programs.”

OASAS certification is a state licensing standard applied to the program regardless of who pays. Many of New York’s strongest programs — hospital-based detox units, established residential providers, academic medical centers — accept Medicaid. Program quality varies, as it does in every payer category, but the payer is not the variable that determines it.

“I make too much to qualify.”

The threshold for a single adult is $1,836 a month, and there is no asset test for this group. People also assess themselves against last year’s income rather than current income. If your earnings recently dropped, apply and let the state make the determination.

“I’ll have to pay Medicaid back.”

Estate recovery in New York applies to long-term care services for members 55 and older, not to ordinary medical and behavioral health care for working-age adults. Addiction treatment covered for an adult under 55 does not create a debt to be repaid.

“No rehab will take Medicaid.”

Hundreds of OASAS-certified programs across the state accept it, including residential programs. The real constraint is availability at a given level of care in a given region at a given moment — which is a scheduling problem with workarounds, not a coverage problem.

“My employer will find out.”

Federal law gives substance use disorder treatment records confidentiality protections stricter than ordinary medical privacy. Enrolling in Medicaid does not notify your employer, and treatment records are not disclosed to them.

Frequently Asked Questions

Does New York Medicaid cover drug and alcohol rehab?

Yes, across the full continuum — medically managed and medically supervised withdrawal, inpatient rehabilitation, residential treatment, outpatient and intensive outpatient programs, opioid treatment programs, and medication-assisted treatment. Coverage extends to youth-specific programs as well.

How much does rehab cost with New York Medicaid?

For most people, nothing. Visits to alcohol, substance abuse, and methadone clinics are exempt from copays under New York Medicaid policy. Where copays apply to other services, they are capped at $200 per year with a $50 quarterly ceiling, and members under 21, pregnant members, and members below 100% of the federal poverty level are exempt entirely. There are no premiums and no deductible.

What is the income limit for Medicaid in New York?

For most adults aged 19 to 64, the limit is 138% of the federal poverty level — $1,836 per month or $22,025 per year for a single person, and $2,489 per month or $29,864 per year for a household of two. There is no asset test for this group, and income is counted on a current basis using modified adjusted gross income.

Does Medicaid cover inpatient and residential rehab in New York?

Yes to both. Inpatient rehabilitation and residential substance use disorder services — including stabilization, rehabilitation, and reintegration residential programs — are covered. This is notable because residential SUD services are not covered under Medicare Advantage plans in New York.

Can Medicaid pay for treatment I already received?

Often, yes. New York Medicaid has a retroactive eligibility period covering up to three months before the month you apply, beginning on the first day of the third preceding month. You must report that you had paid or unpaid medical bills during that period; when you do, eligibility for those months has to be determined. Bills you already paid may also be eligible for reimbursement.

How long does it take to get New York Medicaid?

Standard applications are processed within 45 days, 30 days for pregnant members and children, and up to 90 days where a disability determination is required. The retroactive rule means treatment received during the wait can still be covered once you are approved, and many hospitals and OASAS-certified programs can help screen and file on the spot.

Does Medicaid require prior authorization for rehab in New York?

Generally no for inpatient substance use disorder treatment at an OASAS-certified facility in your plan’s network, and none for outpatient SUD treatment at a licensed facility or for SUD medications. Plans also may not conduct medical-necessity review during the first 28 days of inpatient treatment when the facility notifies the plan within two business days and performs daily clinical review.

How many times will Medicaid pay for rehab?

There is no set limit on treatment episodes. Continued coverage depends on documented clinical need assessed against LOCADTR 3.0 or another OASAS-approved tool. Relapse does not disqualify someone from further covered treatment.

What is HARP and how do I get on it?

A Health and Recovery Plan is Medicaid managed care designed for adults with significant behavioral health needs. It adds mandatory Health Home care management and, for eligible members, Behavioral Health Home and Community Based Services covering employment support, housing assistance, peer support, independent living skills, and crisis prevention. Eligibility is determined through an assessment by a Health Home care manager — ask your plan or care manager directly.

Does Medicaid pay for transportation to treatment?

Yes. New York Medicaid covers non-emergency medical transportation through Medical Answering Services, including public transit fare, taxi and livery, ambulette, and mileage reimbursement. Arrange trips at least 72 hours ahead at medanswering.com or by calling (844) 666-6270 downstate or (866) 932-7740 upstate.

What happens if my Medicaid plan denies treatment?

File a plan appeal — generally within 60 days, but within 10 days if you want services to continue while it is decided. Plan appeals are decided within 30 days, or 72 hours when expedited. After a final adverse determination you have at least 120 days to request a State Fair Hearing. Free help is available from CHAMP, the state behavioral health ombudsman, at (888) 614-5400.

The Next Step

If you have New York Medicaid, the coverage question is largely settled. What remains is matching a level of care to a program that has an opening and takes your specific plan — and, if you are not enrolled yet, getting an application in today so the retroactive window starts working in your favor.

A specialist can confirm your plan and its network, identify OASAS-certified programs with current availability, and help arrange transportation and admission. Free, confidential, and no obligation.
