Senate Bill 121 sets rules for how health insurers calculate payments to healthcare providers when there is no contract in place. The bill requires insurers to use a consistent method based on up-to-date data on what providers charge across Alaska. Payments must be at least at the 75th percentile of provider charges, with higher rates for primary care services. The bill also calls for regular audits and updates to these rates, ensuring fairness and transparency in how insurers reimburse healthcare providers. It takes effect January 1, 2026.
