In Kentucky Association of Health Plans, Inc. v. Miller,, the Supreme Court unanimously held that states’ “any willing provider” laws are not preempted by the Employee Retirement Income Security Act of 1974 (ERISA). The Court ruled that states can regulate their health maintenance organizations (HMOs), and thus upheld a Kentucky law that requires insurers to reimburse services of any health care provider who is willing and able to meet established criteria. The Supreme Court has heard several cases related to ERISA in the last few years, and other such cases are working their way through the court system. Coupled with this most recent decision in Miller, the Supreme Court may significantly alter the shape of the insurance industry.
