Key points

Since April 1, 2023, Medicaid members in mainstream managed care plans get prescriptions through NYRx, so one statewide drug list applies regardless of plan.
On the NYRx preferred drug list revised September 14, 2026, most generic stimulants are preferred and need no prior authorization for adults.
For lisdexamfetamine capsules the brand, Vyvanse, is preferred and the generic capsule is non-preferred; the generic chewable tablet is preferred.
Prior authorization applies when a stimulant is started for someone already taking an opioid, a benzodiazepine or opioid dependence therapy, and for non-preferred products.
NYRx copays are $1 for generics and preferred brands and $3 for non-preferred brands, capped at $50 per quarter, and a pharmacy cannot refuse a drug because a member cannot pay the copay.

Medicaid in New York covers adults aged 19 to 64 with income at or below 138 percent of the federal poverty level, which the Department of Health lists as $1,836 a month for one person in 2026, with no resource test. For an adult with ADHD, coverage has two parts that run on different tracks: visits go through your managed care plan, and medication goes through the State.

Visits: an ADHD evaluation is ordinary psychiatric care

No Department of Health page was found that describes adult ADHD evaluation as its own Medicaid benefit. Medicaid covers outpatient mental health services and prescription drugs, and an ADHD evaluation is a psychiatric diagnostic evaluation like any other. Members enrolled in a Medicaid Managed Care plan use that plan's network for visits.

Neuropsychological testing is a different matter. Coverage and prior authorization rules for testing were not confirmed on a State page, so ask your plan before scheduling. Testing is not required for an adult diagnosis in standard practice; see clinical evaluation or neuropsychological testing.

Medication: NYRx, not your plan

Since April 1, 2023, members of mainstream Medicaid Managed Care plans, Health and Recovery Plans (HARPs) and HIV Special Needs Plans have received prescription drugs through NYRx, the state-run Medicaid pharmacy program. Your health plan no longer decides which drugs are covered. The result is that the rules for ADHD medication are the same for every member, whichever plan card you carry.

Two groups are outside NYRx: people in Managed Long-Term Care plans, and people in the Essential Plan, which is a separate program with plan-run formularies (see the Essential Plan and marketplace plans).

What the preferred drug list says about stimulants

NYRx publishes a preferred drug list (PDL). Preferred drugs generally need no prior authorization. Non-preferred drugs do. The version read for this article is marked revised September 14, 2026. The list is updated regularly, so check the current version before relying on any entry.

Rule on the September 14, 2026 list	What it means for an adult
Diagnosis must be an FDA-approved or compendia-supported indication that Medicaid covers	The prescription needs a qualifying diagnosis on it. This applies at all ages.
Prior authorization for initial stimulant prescriptions under age 3	Does not affect adults. The list has no adult age cutoff.
Prior authorization to start a stimulant for a patient currently on an opioid	Your prescriber must request approval first.
Prior authorization to start a stimulant for a patient currently on a benzodiazepine	Same.
Prior authorization to start a stimulant for a patient established on opioid dependence therapy	Same.
Quantity limits based on daily dosage in FDA labeling, with dose-optimization limits on some long-acting products	The pharmacy claim can reject if the quantity exceeds the limit.

Preferred products on that list include generic immediate-release and extended-release amphetamine salt combinations, generic methylphenidate tablets and several generic extended-release methylphenidate products, generic dexmethylphenidate in both forms, and dextroamphetamine tablets. These are named as examples of what the list contains, not as recommendations.

The lisdexamfetamine exception

Most people expect Medicaid to prefer the generic. For lisdexamfetamine capsules, NYRx does the reverse.

Vyvanse brand capsules: preferred, under the State's Brand Less Than Generic program.
Generic lisdexamfetamine capsules: non-preferred, so they need prior authorization.
Generic lisdexamfetamine chewable tablets: preferred.

If a pharmacy tells you a lisdexamfetamine capsule prescription was rejected, this is a likely reason. Ask the pharmacist whether the brand can be dispensed instead, and let the prescriber's office know. For most other stimulants on the list the pattern is the usual one, with generics preferred and several brand-name products non-preferred.

Non-stimulant medication

In the list's separate class for other ADHD agents, atomoxetine, clonidine ER and guanfacine ER are preferred. Several brand-name non-stimulants are non-preferred. The diagnosis check in this class is written for patients under 18, and no adult diagnosis edit is listed.

Copays

Drug type	NYRx copay
Generic, preferred brand, Brand Less Than Generic	$1.00
Non-preferred brand	$3.00
Over-the-counter	$0.50

Copays are capped at $50 per quarter, which is $200 over the copay year running April 1 to March 31. Some members are exempt, including those under 21, pregnant members and members with income below 100 percent of the poverty level. Psychotropic drugs are also listed as exempt, but whether stimulants are counted in that category was not confirmed, so expect $0 to $3 per prescription. No one can be denied a drug for inability to pay the copay.

Finding a prescriber who takes Medicaid

Coverage on paper only helps if someone will see you.

Ask your plan for a list. It must provide available in-network behavioral health providers within 3 business days of a request.
Use the appointment standard. Medicaid Managed Care plans must offer a first outpatient behavioral health appointment within 10 business days. If yours cannot, file an access complaint with the plan. The steps are in New York's 10-business-day rule. The Medicaid Managed Care complaint line is (800) 206-8125.
Search the OMH directory. The Office of Mental Health's Find a Mental Health Program tool lists programs it operates, licenses or funds, by county.
Ask each clinic directly whether it evaluates adults for ADHD and whether its prescribers will prescribe stimulants. Policies differ, and no State page settles this.

For pharmacy questions, the Medicaid Helpline is (800) 541-2831, and the member site has a pharmacy finder. Confirm numbers on the Department of Health page before calling.

A note on HARPs

A HARP is a Medicaid managed care plan for adults 21 and older with significant behavioral health needs. It combines physical health, mental health and addiction services and adds home and community-based services. Eligibility rests on the State's high-risk criteria, and eligible people are notified by letter. HARP members also get their drugs through NYRx.

If Medicaid is not an option for you, lower-cost adult ADHD care in New York lists other routes. Whether a particular private practice participates with Medicaid is something to check with that practice; for this one, see the fees and insurance page.

Questions

Does New York Medicaid require prior authorization for ADHD stimulants in adults?

Not as a general rule. On the list revised September 14, 2026, preferred stimulants need no prior authorization for adults, although the prescription must carry a covered diagnosis. Prior authorization applies to non-preferred products and when a stimulant is started for someone on an opioid, a benzodiazepine or opioid dependence therapy.

Why did the pharmacy reject my generic Vyvanse under Medicaid?

On the NYRx list, generic lisdexamfetamine capsules are non-preferred and brand Vyvanse capsules are preferred under the Brand Less Than Generic program. Ask the pharmacist and your prescriber about dispensing the brand. The generic chewable tablet is preferred.

Does my Medicaid managed care plan decide which ADHD drugs are covered?

No. Since April 1, 2023, drug coverage for mainstream managed care, HARP and HIV Special Needs Plan members runs through NYRx under one statewide list. Managed Long-Term Care plans and the Essential Plan are the exceptions.

How much is the copay for ADHD medication on Medicaid?

NYRx copays are $1 for generics and preferred brands and $3 for non-preferred brands, with a $50 quarterly maximum. Some members are exempt. A pharmacy cannot refuse to dispense because you are unable to pay the copay.

Is there an age limit for stimulant coverage under New York Medicaid?

The September 2026 preferred drug list has no adult age cutoff. The only age-based prior authorization in the stimulant class is for initial prescriptions for children under 3.
