There is no state law requiring employers to offer group healthcare insurance to their employees, but most employers do offer this benefit. However, if any healthcare insurance is offered, Montana's insurance laws require that employers offer certain benefits (mandated benefits) and place restrictions on some insurance company practices. The law also authorizes limited benefit plans for employers with 20 or fewer employees. There is additional information and details about continuation and conversion requirements..
States are not permitted to regulate self-insured benefit plans. Montana's mandated benefits, insurance restrictions, continuation, and conversion provisions do not apply to health plans in which the employer pays all benefits without the proceeds of any insurance policy. An employer's health plan is self-insured if the risk of paying claims is on the employer and not on an insurance company. Self-insured plans may contract with third-party administrators (TPAs), including insurance companies, to process benefit claims. The TPA pays the claims and then is reimbursed by the employer. Many self-insured plans also buy “stop-loss” insurance to cover very large claims. The purchase of stop-loss insurance does not result in the loss of self-insured status and the exemption from state regulation.
