What the Labor Department Just Told You About Your Next Parity Audit
Most compliance guidance tells you what the rule is. Every so often an agency tells you something more useful: where it is actually going to look.
On September 8, 2026, the Employee Benefits Security Administration issued Field Assistance Bulletin No. 2026-03, and it does exactly that for mental health parity. If your plan has been carrying a comparative analysis built to cover every nonquantitative treatment limitation you could identify, this is the document that tells you which parts of that work an investigator will actually open.
The three places an investigation will go
The bulletin narrows EBSA's enforcement of the nonquantitative treatment limitation requirements to three priority areas.
Separate treatment exclusions. Blanket exclusions that apply to mental health and substance use disorder benefits but are not applied to medical and surgical benefits. This is the cleanest possible parity violation, and it is first on the list for a reason.
Medical necessity review processes. Prior authorization, concurrent review, and retrospective review, where the standards or the intensity of application differ across the two benefit classifications. Not whether you use prior authorization, but whether you use it the same way on both sides of the line.
Network adequacy. Specifically, provider admission standards and reimbursement methodologies that have the effect of restricting in-network access to mental health and substance use providers. This is the area where a plan can look compliant on paper and fail in practice, because the limit is produced by how the network was built rather than by any written rule.
The Department was direct about why it narrowed the scope. It said that its prior approach had created substantial confusion and unnecessary burdens. That is an unusual thing for an agency to say about its own enforcement, and it is worth taking at face value.
What this changes for your plan
Point your next comparative analysis at those three domains. If your analysis is a broad inventory that treats every nonquantitative treatment limitation as equally likely to draw scrutiny, you are spending effort where the agency has told you it is not looking, and possibly spending too little where it is. Re-weight rather than rewrite.
Get the network-adequacy piece out of your TPA in writing. Of the three areas, this is the one a plan sponsor is least likely to be able to document from its own records. Provider admission standards and reimbursement methodologies sit with whoever built the network. Ask for them, ask specifically how mental health and substance use provider reimbursement compares to medical and surgical, and keep the answer.
Put the three areas in the committee minutes. The value of a bulletin like this is not only what it tells you to do; it is that it gives your committee a defensible reason for how it scoped its own work. A minute that records the Department's stated priorities and the plan's decision to align to them is a better record than a minute that records a general intention to comply.
What this does not change
This is the part most summaries will get wrong, so it is worth being precise.
The statutory parity duty is untouched. The bulletin is enforcement guidance. It does not amend the Mental Health Parity and Addiction Equity Act, and it does not relieve a plan of any obligation the statute imposes.
The comparative-analysis requirement is untouched. The obligation to prepare and, on request, produce a comparative analysis comes from the Consolidated Appropriations Act of 2021, not from the 2024 regulation. Narrower enforcement priorities do not make the document optional.
The 2013 rule remains in force. Only the provisions of the 2024 final rule that differ from the 2013 rule are subject to non-enforcement.
And the non-enforcement window is not a date. The bulletin reconfirms that EBSA will not enforce the new 2024-rule provisions until the pending ERISA Industry Committee litigation concludes, plus 18 months. That is a period tied to a case outcome, not a deadline you can put on a calendar. If that litigation resolves sooner than expected, the clock starts sooner. Plans that treat this as an indefinite reprieve are making an assumption the document does not support.
The honest summary
Nothing about your obligations changed on September 8. What changed is that you now know the shape of the question you are most likely to be asked. That is worth something, but only if you do the work of pointing your documentation at it while there is time to do so calmly.

Reviewing whether your plan's parity documentation would hold up is the same exercise as reviewing whether any of your vendor arrangements would. A CLEAR™ review maps your ASO, PBM, and Stop-Loss contracts against the eight fiduciary duties and the current case standards, and returns a written summary you can hand to counsel.

FAQs
Does Field Assistance Bulletin 2026-03 change what my plan has to comply with?
No. It is enforcement guidance describing where EBSA will focus its investigations. The statutory parity requirements, the 2013 regulation, and the CAA 2021 comparative-analysis obligation all remain in force.
Can we stop preparing a comparative analysis?
No. The comparative-analysis requirement comes from the Consolidated Appropriations Act of 2021, not from the 2024 regulation, and it is not affected by the non-enforcement policy.
How long does the non-enforcement period last?
Until the ERISA Industry Committee litigation over the 2024 final rule concludes, plus 18 months. It is tied to a case outcome rather than a fixed date, so it could end earlier or later than a calendar estimate would suggest.
Which of the three priority areas is hardest for a plan sponsor to document?
Network adequacy. Provider admission standards and reimbursement methodologies typically sit with the entity that built the network rather than with the plan, so getting that documentation usually requires a written request to the TPA or carrier.
