Revise laws related to health insurance coverage of behavioral health screening

This bill requires health insurance policies issued or renewed in Montana to cover behavioral health screening assessments using standardized, evidence-based tools at no cost to the insured. It specifically applies to individual disability policies, state employee group benefit plans, disability insurance offered in the state, and self-funded multiple welfare employment arrangements. The legislation amends existing state laws to mandate this coverage while also updating provisions related to continued group plan membership for retirees, surviving spouses, judges, and legislators.
