SB 1156 prohibits health insurance companies from offering higher reimbursement rates to nonaffiliated healthcare providers as an incentive for them to join an affiliated provider network. The bill also bans insurers from paying affiliated providers more than nonaffiliated providers for the same medical service. Additionally, it restricts insurers from directing patients to affiliated providers through marketing, communication, or financial incentives unless it is based on lower reimbursement rates, risk-sharing, or value-based quality metrics. The bill aims to promote fairness in healthcare provider payments and prevent anti-competitive practices in health insurance networks​.
