CMS Reimbursement Policy Supporting Care Coordination

Investigators propose to use a natural experiment design to examine the impacts of the new CPT code (99490) for chronic care management on health outcomes. The Investigators will collaborate with partners in the Louisiana Clinical Data Research Network (LaCDRN) who serve more than 90,000 patients with type 2 diabetes mellitus in Louisiana to examine impacts of the CMS reimbursed care coordination. Now, LaCDRN is renamed as Research Action for Health Network (REACHnet). Patient and stakeholder engagement will be planned and implemented across all phases of this natural experiment. This project will examine outcome differences created by the policy change in a natural experiment framework. The analyses will utilize the RE-AIM framework to identify the critical elements of the programs that will enhance the reach, effectiveness, adoption, implementation, and maintenance of these strategies in the diverse LaCDRN diabetes populations.
