Missouri Revised Statutes Title XXIII. Corporations, Associations and Partnerships § 354.546. Second medical opinion to be allowed by health maintenance organizations, procedure, costs

1. A health maintenance organization shall allow enrollees to seek a second medical opinion or consultation from the health maintenance organization's choice of other primary care physicians and specialty physicians at no additional cost to the enrollee beyond what the enrollee would otherwise pay for an initial medical opinion or consultation.

2. If an enrollee chooses to seek a second medical opinion, and if the health maintenance organization does not employ or contract with another physician with the expertise necessary to provide a second medical opinion, then the health maintenance organization shall arrange for a referral to a physician with the necessary expertise to provide a second opinion or consultation and ensure that the enrollee obtains the covered benefit at no greater cost to the enrollee than if the benefit were obtained from participating physicians.
