Generally revise health insurance laws relating to certain conditions

This bill requires health insurance plans issued in Montana to cover specific diabetes and obesity treatments, including glucagon-like peptide-1 receptor agonists, when deemed medically necessary. It applies to individual disability policies, certificates of insurance, and membership contracts but excludes disability income, hospital indemnity, Medicare supplement, specified disease, and long-term care policies. The legislation defines medically necessary coverage to include diagnoses of diabetes, class 3 obesity, or polycystic ovary syndrome, while allowing standard deductibles and coinsurance but prohibiting special limitations on these specific medications. Additionally, the bill amends existing state laws to permit legislators, judges, and their spouses to continue group health plan membership after leaving office under certain conditions.
