Final answer:
Managed care is essential in Workers' compensation insurance, providing comprehensive coverage and facilitating quality treatment and return to work processes for injured employees.
Step-by-step explanation:
The Workers' compensation insurance program is a system designed to protect employees who get injured on the job by providing financial benefits. Managed care plays a crucial role in this program as it aims to improve the quality of medical benefits and services received by injured workers. Without the managed care aspect, the program would likely struggle with the provision of quality medical treatment, efficient healing processes, and the return to work of injured employees. Managed care contributes to more comprehensive coverage, appropriate medical treatments, and the presence of internal grievance and dispute resolution processes. These elements of managed care are essential in the intricate process of dealing with temporary and permanent disabilities, vocational rehabilitation, and survivor benefits, areas that are more complex than the filing of claims for minor injuries or illnesses.
