Relating to: mandatory participation in the Wisconsin Health Information Organization. (FE)

AB 801 establishes a mandatory "all-payer claims database" requiring insurers, healthcare administrators, and managed care organizations (including those serving Medicaid recipients) to submit health claims data in machine-readable format. It mandates data submission within six months of the law's effective date, with standardized electronic reporting and annual submission schedules. The data organization must analyze and publicly report on healthcare costs, quality, and effectiveness in plain language, while restricting data sharing to purposes like public health research or policy decisions. The bill repeals prior requirements and creates new provisions to standardize data collection, reporting, and transparency for the Wisconsin Health Information Organization.
