The role of insurance in preventive health care is to support access to necessary health screenings, vaccinations, and wellness programs, which can reduce long-term health costs. Insurance plans often cover preventive services to encourage proactive health management, ultimately lowering the risk of chronic diseases. Furthermore, investing in preventive care helps create a healthier population, reducing strain on healthcare systems. By emphasizing prevention, insurance policies can foster better health outcomes and lower medical expenses in the long run.
