The New Era of Mental Health Parity Enforcement in 2026
Federal agencies have made mental health parity enforcement a top priority in 2026, and employers sponsoring group health plans are feeling the impact. Regulators are no longer satisfied with high‑level assurances that plans comply with the Mental Health Parity and Addiction Equity Act (MHPAEA). Instead, they expect detailed, data‑driven documentation showing that mental health and substance‑use‑disorder benefits are truly comparable to medical and surgical benefits. This includes not only the written plan design but also how rules are applied in real‑world scenarios.
