New York's mental health parity law and adult ADHD: what it requires and what changed in 2024 to 2026

Parity is the idea that an insurance plan should treat mental health care the way it treats care for diabetes or a broken arm. New York has written that idea into its Insurance Law in stages over twenty years. For an adult with ADHD, the result matters in concrete ways: whether an evaluation is covered, how a plan reviews ongoing medication visits, and what you can demand to see when a claim is denied. This article walks through the law itself and the recent changes. The broader coverage picture is in does insurance cover adult ADHD care in New York.

How New York's parity law developed

Timothy's Law is still the name many people know, but the coverage that reaches adult ADHD today comes from the broader DSM-based mandate, not from Timothy's Law's original list.

What the statute says today

Insurance Law section 3221(l)(5) applies to group and school blanket policies that cover hospital care or physician services. Section 4303(g) applies the same rules to medical expense indemnity, hospital service and health service corporations, and the Office of Mental Health's 2024 FAQ cites section 3216(i)(35) alongside them. The key parts:

• Coverage. Policies must cover the diagnosis and treatment of mental health conditions, including outpatient care from psychiatrists, psychologists, licensed clinical social workers and nurse practitioners.
• Definition. A mental health condition is any mental health disorder defined in the most recent edition of the DSM, or another generally recognized standard such as the ICD. ADHD is a DSM diagnosis, so it is included.
• Parity. A policy may not apply financial requirements or treatment limitations to mental health benefits that are more restrictive than the predominant ones applied to substantially all medical and surgical benefits.
• Hidden limits count. "Treatment limitation" includes nonquantitative limits, such as medical management standards, network tier design and the standards for admitting providers to a network, including reimbursement rates.
• Criteria on request. The insurer must make its medical necessity criteria for mental health benefits available to insureds and in-network providers who ask.
• Federal floor. Coverage must, at a minimum, be consistent with the federal Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act of 2008.

How parity applies to common ADHD claims

Parity does not decide whether a particular service is medically necessary. It decides whether the plan is treating mental health care by the same rules as medical care. Some examples of how that comparison works:

• Prior authorization for medication. A plan may require approval for some ADHD medications. Under parity, the process should not be stricter than the one it uses for comparable medical drugs. Medication coverage is covered in ADHD medication cost in New York.
• Repeated reviews of ongoing visits. A plan that reviews every few months whether monthly ADHD follow-up is still necessary, but rarely reviews ongoing care for a medical condition, raises a parity question.
• Network and payment rules. Network tier design and the standards for admitting providers to a network, including reimbursement rates, count as treatment limitations under the statute's definition. Showing a violation means comparing the plan's own processes, which is why the plan's documents matter.
• Copays. The cap tying the mental health copay to a primary care copay applies to OMH-licensed outpatient facilities, not to a private psychiatrist's office.

The 2024 to 2026 changes in more detail

The Medicaid-rate floor. The Office of Mental Health's FAQ explains that Part AA of Chapter 57 of the Laws of 2024 amended sections 3216, 3221 and 4303 so that insurers must pay in-network facilities licensed under Mental Hygiene Law Article 31 at least the Medicaid rate for covered outpatient mental health care, and the same for OASAS outpatient programs. It applies to policies issued or renewed on or after 1 January 2025. The FAQ lists the facility types it covers, such as licensed outpatient clinics, partial hospitalization programs and crisis stabilization centers; individual private practices are not on that list.

Wait-time standards. Since 1 July 2025, New York-regulated plans must offer a first outpatient behavioral health appointment within 10 business days of a request. If they cannot, an access complaint can lead to an out-of-network referral at in-network cost. The steps are in can't find an in-network ADHD psychiatrist.

The 2026-27 budget. The State Senate's summary says insurers are now prohibited from conducting more than one utilization review per year for individuals with chronic conditions, and that continuity of care was extended to 90 days for all conditions. The Mental Health Association in New York State's report on the enacted budget defines a chronic health condition as one expected to last at least a year that requires ongoing treatment, and says a new course of treatment can still be reviewed. Whether a particular insurer will treat adult ADHD as a chronic condition under that definition, and exactly when the provisions take effect, could not be confirmed as of October 2026. Ask your plan in writing.

What parity law does not do

• It does not apply to self-funded employer plans, which follow federal law only.
• It does not make care free. Deductibles, copays and coinsurance still apply.
• It does not require a plan to cover any specific medication or test it considers not medically necessary, although you can appeal.
• It does not set what a private psychiatrist charges or is paid.

At the federal level, the agencies said in May 2025 that they would not enforce the parts of the 2024 federal parity rule that were new while they reconsidered it; the 2008 statute and the earlier 2013 rule still apply.

Using your parity rights

1. Get the denial in writing. Note the reason and the criteria cited.
2. Ask for the medical necessity criteria the plan used, which section 3221(l)(5) entitles you to request.
3. Ask how the plan handles comparable medical care, for example whether it requires the same prior authorization or review frequency.
4. Appeal. You have 180 days to appeal with a New York-regulated insurer, then a possible external appeal. See appealing an insurance denial.
5. Get help. CHAMP, the state's behavioral health ombudsman, takes calls at (888) 614-5400, and DFS takes complaints about insurers at (800) 342-3736.

DFS also posts the parity reports that insurers file, which you can use to see how a plan's mental health denial rates compare with its medical ones.
