Mental health parity bill fails after long debate over coverage scope and cost

House Bill 123, which would have required insurers to offer mental-health coverage for a defined set of diagnoses with a phased approach to parity, failed on final passage after an extended floor debate that included multiple amendments and fiscal questions. Representative Brian Holliday introduced the bill and framed it as a limited step toward broader parity rather than an immediate, sweeping mandate.

The bill as presented emphasized coverage for seven major categories of mental illness with phased increases (50% first year, 75% second year, then up to full parity). Sponsors said the bill was not a mandate on employers but would require insurers to offer options; exemptions were proposed for smaller employers (the threshold discussed included firms with 50 or fewer employees). Representative Bennion and others offered amendments to exclude small groups and fine-tune statutory language; Representative Jones proposed a broader amendment to cover "all mental health diagnoses currently covered by the insurer," which was debated and defeated on the floor.

Opponents raised concerns about the fiscal note and the potential cost to employers and the state. One member warned that every addition of mandatory coverage eventually requires funding and could shift costs to taxpayers or drive employers to drop benefits. Supporters, including health plan representatives and mental-health advocates, urged the chamber to address an existing coverage gap and emphasized potential productivity gains and reduced societal costs. After the House called the previous question to end debate, the final roll-call recorded 27 yes and 44 no, and the bill failed.
