If your health insurance covers physical health conditions, it is legally required to cover mental health and substance use disorder treatment at the same level — or better. This principle, called mental health parity, is the law in New York and nationally. Yet insurance companies routinely violate it, and most policyholders don’t know how to fight back. This guide explains your parity rights, how to identify violations, and how to appeal when your insurance company denies or limits mental health coverage.
What Is Mental Health Parity?
Mental health parity means that health insurance plans cannot impose more restrictive treatment limitations on mental health and substance use disorder (MH/SUD) benefits than they apply to medical and surgical benefits. This includes:
- Financial requirements: Copays, deductibles, and out-of-pocket limits for MH/SUD must be no more restrictive than those for medical benefits at the same coverage tier
- Treatment limitations: Day limits, visit limits, and frequency limits on mental health treatment cannot be more restrictive than limits applied to comparable medical treatment
- Prior authorization: Requirements for pre-approval of mental health care cannot be more burdensome than requirements for medical care
- Network adequacy: The insurer must maintain an adequate network of mental health providers comparable to its network for medical providers
The Laws That Protect You
- Federal Mental Health Parity and Addiction Equity Act (MHPAEA): Applies to most employer-sponsored health plans and large group insurers
- New York Mental Health Parity Law: One of the strongest state parity laws — requires coverage for biologically based mental health conditions to be identical to medical coverage with no annual or lifetime dollar limits
- Affordable Care Act (ACA): Requires all marketplace and individual plans to cover mental health as an essential health benefit with parity protections
- New York Insurance Law Section 3221(l)(5) and 4303: NY-specific parity requirements for insured plans
Common Parity Violations
Insurance companies frequently violate parity in ways that are not obvious to policyholders:
- Applying visit limits to therapy (e.g., “30 visits per year”) when no comparable limit applies to physical therapy or other ongoing medical treatment
- Requiring prior authorization for mental health care that is not required for equivalent medical care
- Applying stricter “medical necessity” review standards to mental health claims than to physical health claims
- Maintaining inadequate networks of in-network mental health providers while having adequate medical networks — forcing you to pay out-of-network rates
- Denying residential mental health treatment while covering residential treatment for physical conditions
How to Fight a Parity Violation
Step 1: Get the Denial in Writing
If your insurance company denies, limits, or requires prior authorization for mental health care, get the denial in writing. The denial letter must state the specific reason and the clinical criteria used. Request the “criteria used to deny” — insurers are required to provide these on request.
Step 2: File an Internal Appeal
File an internal appeal with your insurance company within the timeframe specified in your plan documents (usually 30–180 days). For mental health denials, request a reviewer with mental health expertise. Include a letter from your treating clinician explaining medical necessity.
Step 3: File an External Appeal
If your internal appeal is denied, you can request an independent external appeal. In New York, external appeals of insurance denials go to an independent organization designated by the NYS Department of Financial Services. The external reviewer’s decision is binding on the insurer.

Step 4: File a Parity Complaint
File a formal parity complaint with:
- NYS Department of Financial Services (DFS): (800) 342-3736 | dfs.ny.gov — regulates NY-licensed insurance companies
- U.S. Department of Labor (for employer-sponsored ERISA plans): 1-866-444-3272 | dol.gov/ebsa
- NYS Attorney General: (212) 416-8090 — for systemic violations affecting many policyholders
Network Adequacy: A Special Parity Issue
One of the most common ways insurers violate parity is maintaining inadequate mental health provider networks. If you cannot find an in-network mental health provider accepting new patients after a reasonable search, you may be entitled to out-of-network reimbursement at in-network rates — this is called a “network adequacy” exception. Contact your insurer and document your failed attempts to find an in-network provider. If they deny the exception, file a complaint with DFS.

Frequently Asked Questions
My insurance limits me to 20 therapy sessions per year. Is that legal?
It depends. If your plan also limits other ongoing outpatient treatment to 20 visits per year (like physical therapy or cardiac rehab), the limit may be parity-compliant. But if no comparable visit limit applies to medical treatment, this may be a parity violation. Request your plan’s treatment limitation details and compare mental health to medical benefits. File a complaint with DFS if limits are applied unequally.
My insurer requires prior authorization for mental health appointments but not for primary care visits. Is that a parity violation?
Likely yes. Prior authorization requirements for mental health care that are not applied to comparable medical care are a recognized form of parity violation. Document the disparity and file a complaint with DFS at (800) 342-3736.
I can’t find any in-network therapists accepting new patients. What are my rights?
Document your attempts to find an in-network provider (dates called, names, responses). Contact your insurer and request a network adequacy exception authorizing out-of-network treatment at in-network rates. If denied, file a complaint with the NYS Department of Financial Services — inadequate mental health networks are a parity violation that DFS actively investigates.
Does parity apply to Medicaid in New York?
Yes. Federal law requires parity for Medicaid managed care plans, and New York’s parity requirements apply to Medicaid managed care as well. If your Medicaid managed care plan is denying or limiting mental health benefits more restrictively than medical benefits, file a complaint with NYS DFS or the NYS Department of Health at (888) 343-9000.
