I request that the denial be overturned and the mental health parity approved. 1. The denial. [Insurer] denied this mental health parity stating, verbatim: "[paste the exact denial language from your letter]." 2. Why the denial is incorrect. [State, in one or two sentences, why the service is medically necessary for your condition, and answer the specific reason the plan gave.] 3. The controlling standard. [See the standard for this denial type below, then cite it here.] 4. The evidence. I am attaching: - A letter of medical necessity from my treating provider addressing each clinical criterion; - [Your supporting records: see the document checklist below]; - The clinical guidelines and records that support coverage. 5. My request. I request a full reversal of this denial and approval of [service or medication] within the timeframe required by law. If the denial is upheld, please provide in writing the specific clinical criteria used, the credentials of the reviewing clinician, and instructions for independent external review. Under 29 C.F.R. 2560.503-1 (employer plans) or 45 C.F.R. 147.136 (ACA plans), please also provide all documents and records relevant to this claim. Sincerely, [Patient name / authorized representative]
The controlling standard for mental health parity denials
The Mental Health Parity and Addiction Equity Act (29 U.S.C. § 1185a; 45 C.F.R. § 146.136) requires the plan to produce its NQTL comparative analysis on demand.
What makes a mental health parity appeal letter win
Request the plan's non-quantitative treatment limitation (NQTL) analysis under MHPAEA, federal law requires plans to produce it on demand. Compare the criteria used for the denied MH service against criteria for an analogous medical/surgical service. File parallel complaints with the U.S. Department of Labor (for ERISA plans) or the state DOI (for fully-insured plans). Cite Wit v. United Behavioral Health for behavioral level-of-care cases.
The letters that get overturned share a structure: they quote the denial, rebut the plan's specific criteria point by point, cite the controlling standard above, attach a treating-provider letter of medical necessity, and make a clear demand for reversal. Generic letters that simply ask the plan to reconsider do not move reviewers.
Documents to attach
- Denial letter
- Plan's medical-necessity criteria for the denied service
- Plan's medical-necessity criteria for an analogous medical/surgical service
- Treating clinician's letter and treatment plan
- Documentation of prior levels of care attempted (if applicable)

Build my appeal free →Mental health parity appeal: frequently asked questions
Can I appeal your my insurer mental health denial under parity law?
Yes. The Mental Health Parity and Addiction Equity Act bars plans from applying stricter limits to mental health and substance-use benefits than to comparable medical or surgical benefits. Many denials violate parity, which is a powerful reversal lever.
How do I prove a parity violation?
Request the plan's non-quantitative treatment limitation (NQTL) comparative analysis, which federal law requires your insurer to produce on demand, then compare the criteria used for your denied service against the criteria for an analogous medical or surgical service.
Where else can I report a parity violation?
You can file in parallel with the U.S. Department of Labor for an ERISA plan, or your state insurance regulator for a fully-insured plan, at any time, in addition to the internal and external appeal.
What is the deadline for a mental-health parity appeal?
Internal appeals are due within 180 days and external review within roughly 4 months of the final internal denial. Parity complaints to regulators have no fixed appeal deadline.
