Update on COVID-19


Physical Medicine

Effective June 1, 2020, physical medicine services (physical therapy, occupational therapy and speech therapy) will no longer be managed through a post-service review process. Therefore, beginning June 1, 2020, Sunflower Health Plan will implement a prior authorization of outpatient physical medicine services for its membership.
