MCO Open Enrollment 

Managed Care Organizations (MCOs) handle the medical management of workers’ compensation claims. MCOs are required for Ohio employers, and are responsible for approving treatment, paying medical bills, and facilitating return-to-work. Open Enrollment is a four week period, offered every 2 years, in which employers can make a change in their MCO. The next open enrollment period will begin in May 2018.

Here are five important ways choosing the right MCO can help when workplace injuries occur.
