A nurse is educating a group of nursing students about the different types of health care delivery models. Which of the following statements by a student indicates an understanding of managed care?

A. The goal of managed care is to reduce health care costs while improving quality. Managed care delivery models focus on the integration of financing and delivery of health services to ensure efficiency. By emphasizing preventative care and utilizing utilization reviews, these systems aim to provide high-quality care at a lower total cost. This approach streamlines patient outcomes through evidence-based practice and standardized care protocols. B. Fee-for-service is the most common form of managed care. Fee-for-service is the traditional reimbursement model where providers are paid for each individual procedure or visit performed. This model actually incentivizes higher volumes of services rather than the cost-containment goals of managed care. Managed care typically uses capitation or bundled payments to encourage financial responsibility and coordination. C. Managed care allows patients to choose any provider without restrictions. Most managed care plans, such as HMOs and PPOs, utilize a specific network of contracted providers to control costs. Patients who choose out-of-network providers often face significantly higher out-of-pocket expenses or no coverage at all. This network restriction is a key mechanism used to manage the quality and price of healthcare services. D. Managed care plans do not require preauthorization for specialist visits. Managed care systems frequently utilize "gatekeepers," usually primary care physicians, who must provide referrals for specialized treatment. Preauthorization is a standard administrative requirement to ensure that expensive procedures or specialist consultations are medically necessary. This oversight prevents the overutilization of specialized healthcare resources and maintains cost-effectiveness.
