What to do
Work out whether a behavioural-health limitation is actually in play
Parity bites when the plan applies a mental-health or substance-use limitation. A letter requirement, a diagnosis prerequisite, or a counseling condition is often where the hook is.
Identify the limitation as non-quantitative
Prior authorization, medical-necessity criteria, network admission standards, and reimbursement rates are all non-quantitative treatment limitations, abbreviated NQTL in plan documents and regulator correspondence. Name which one you are challenging.
Request the comparative analysis in writing
Plans must produce a written comparative analysis showing the limitation is applied no more stringently than to comparable medical and surgical benefits. Ask for it as a document, by that name.
Read it for the comparison, not the conclusion
The analysis has to compare. An analysis that describes the behavioural-health side and never sets it beside a surgical benefit has not done the work.
Escalate the failure to produce, separately from the denial
Not producing an adequate comparative analysis is its own violation. The Department of Labor takes complaints about it for self-funded plans; state regulators for insured ones.
Get advice before you build a case on this
Parity arguments are technical and the rules are in flux. This is the point to bring in an advocacy organization or counsel.
What is paused and what is not
The 2024 parity rule is under a federal non-enforcement policy tied to pending litigation, and the departments have signalled they may rescind or modify it. That is a real change and anyone telling you the 2024 requirements are being enforced is out of date.
What did not change: the 2013 rules, the statutory obligation to produce a comparative analysis on request, your right to obtain it, and your right to sue. The floor is lower than it was in 2024. It is not zero.
The honest limit of this argument
Parity is about comparison, not about whether the care is good. If a plan applies the same criteria to gender-affirming surgery that it applies to comparable surgical benefits, parity has nothing to say, however wrong the denial is on the clinical merits. Use it where the asymmetry is real and documented.
Common questions
- Is parity law still enforceable?
- The 2013 rules and the statutory comparative-analysis duty are. The newest 2024 requirements are under a federal non-enforcement policy, so do not build an argument that depends on them.
- What is a non-quantitative treatment limitation?
- A non-quantitative treatment limitation, or NQTL, is a limit that is not a number: prior authorization, medical-necessity criteria, standards for admitting providers to a network, or how reimbursement is set.
- Do I get the comparative analysis just by asking?
- Plans are obliged to produce one on request. Whether what arrives is adequate is a separate question, and inadequacy is itself something to raise.

29 CFR 2590.712 and 2590.712-1 — current text still carries the 2024 rule (definitions keyed to 22 November 2024), so the rule was not rescinded. The May 2025 non-enforcement policy is sub-regulatory and was NOT located in the Federal Register, so it remains unverified
