The above distinctions become particularly important when determining whether or not a state insurance law applies to your insurance plan.
ERISA. For example, pursuant to the Federal Employee Retirement Income Security Act (ERISA), self-insuring businesses are not required to comply with state insurance mandates, although they may voluntarily provide these mandated benefits. Therefore, a state law requiring insurance companies to cover infertility cannot apply to companies that “self-insure,” that is, which do not purchase insurance policies but instead pay medical claims themselves. This is because ERISA prevents states from being able to regulate self-insured companies. However, if drafted correctly, a federal law requiring insurance for diagnosis and treatment of infertility could overcome ERISA and could require all, or at least more, employers to provide infertility insurance.
Unlike typical pregnancy-related services guaranteed nationally as basic health plan benefits under the National Pregnancy Discrimination Act, infertility treatment services are not similarly ensured. Coverage, particularly for assisted reproductive technologies, is extremely limited. In the United States, only one in five employers provide infertility treatment benefits to their employees and these policies vary widely in their comprehensiveness, reimbursement limits, and eligibility requirements.
Although no federal law requires insurance coverage for infertility treatment, some states have enacted some type of infertility insurance coverage law. Each law is different, but most can be generally described as either a mandate to cover or a mandate to offer. Follow this link for complete list of state laws.
Mandate to Cover: is a law requiring that health insurance companies provide coverage of infertility treatment as a benefit included in every policy (policy premium includes cost of infertility treatment coverage).
Mandate to Offer: is a law requiring that health insurance companies make available for purchase a policy which offers coverage of infertility treatment (but the law does not require employers to pay for the infertility treatment coverage).
