Relative to the joint negotiation prohibition for integrated systems in health care. A facility that is either affiliated or owned by a system shall negotiate separate contracts by facility with public and private payers. Each facility that is subject to this section that is within a larger system shall establish separate negotiating teams. Every facility that is subject to this section shall establish a firewall mechanism that prevents the separate contract negotiating teams from sharing any information that would inhibit them from competing with each other and with other hospitals and physician practice groups. Contracts between a facility and carrier may not be contingent on entering into a contract with another health care provider within a system. Contracts between a facility and carrier may not make the availability of any price or term for a contract contingent on the carrier entering into a contract with another health care facility. The department and the office of the attorney general shall have the authority to enforce the requirements of this section.
