Relative to market oversight in health care. Health Care Financing. Every provider or provider organization shall, before making any material change to its operations or governance structure, submit notice to the commission, the center and the attorney general of such change, not fewer than 60 days before the date of the proposed change. Material changes shall include, but not be limited to: a corporate merger, acquisition or affiliation of a provider or provider organization and a carrier; mergers or acquisitions of hospitals or hospital systems; acquisition of insolvent provider organizations; and mergers or acquisitions of provider organizations which will result in a provider organization having a near-majority of market share in a given service or region. Within 30 days of receipt of a notice filed under the commission’s regulations, the commission shall conduct a preliminary review to determine whether the material change is likely to result in a significant impact on the commonwealth’s ability to meet the health care cost growth benchmark, established in section 9, or on the competitive market. If the commission finds that the material change is likely to have a significant impact on the commonwealth’s ability to meet the health care cost growth benchmark, or on the competitive market, the commission shall conduct a cost and market impact review under this section.
