Insurance Appeal Rights in New York
Payers operating in New York must respond to appeals within 45 calendar days under NY Ins. Law § 3224-a. New York also has independent state parity law that provides protections equal to or stronger than federal MHPAEA — enforcement continues even under the 2025 federal non-enforcement of the 2024 MHPAEA Final Rule.
Prompt-payment window
45 days
calendar days for payer to respond
NY Ins. Law § 3224-a
30 days for EFT / 45 days paper for clean claims. Appeals: 60 days for the payer to respond per NYS DFS guidance. Mental Health Parity Law (Ins. Law § 3221(l)) applies.
Your state insurance commissioner
For New York, contact your state's Department of Insurance to file a complaint, request external review, or verify prompt-payment compliance. Look up the official contact via the NAIC consumer locator.
Note: Self-funded ERISA plans are generally exempt from state insurance regulation. If your patient's plan is employer-sponsored and self-funded, your remedies run through the U.S. Department of Labor (EBSA) rather than the state commissioner.
MHPAEA and state parity overlay
New York has stronger-than-federal parity protections
New York's Mental Health Parity Law (Ins. Law § 3221(l)) applies to fully insured plans and requires parity in coverage, copays, deductibles, and out-of-pocket maximums for mental health and SUD. The NY Department of Financial Services (DFS) enforces parity independently. NYDFS has taken enforcement actions against payers for NQTL violations since 2022, and those actions continue regardless of federal non-enforcement.
Statute: NY Ins. Law § 3221(l); NY Mental Health Law § 43
When filing a behavioral health appeal in New York, invoke both federal MHPAEA (29 CFR § 2590.712) and your state statute. Request the payer's NQTL comparative analysis under CAA 2021 § 203 — the state enforcement authority can independently require compliance.

What is an NQTL and why does it matter?
