2013 MHPAEA Final Rule

The 2013 MHPAEA Final Rule (29 CFR § 2590.712) implemented the 2008 MHPAEA statute and established the framework for evaluating financial requirements, quantitative treatment limitations, and non-quantitative treatment limitations (NQTLs). It remains fully in force and is the primary federal regulation a therapist should cite in an appeal. The subsequent 2024 Final Rule updated NQTL standards, but the 2024 rule's NQTL provisions are under federal non-enforcement as of May 2025 — the 2013 rule fills that gap.
