Minn. Stat. § 60B.193

Upon any Minnesota state district court's order of rehabilitation or liquidation of a health maintenance organization under this chapter, all providers of health care goods or services to enrollees of the health maintenance organization, regardless of whether they have a written contract with the health maintenance organization, are prohibited from attempting to collect or collecting payment for authorized referrals from any enrollee of the health maintenance organization for goods or services to the extent the health maintenance organization is obligated to cover the goods and services under a health maintenance contract with the enrollee. A provider's only recourse is to file a claim against the health maintenance organization in the insolvency proceeding and to receive payment in the proceeding.
