NDI has relationships with over 15,000 preferred providers including laboratory patient service centers, occupational and urgent care medical facilities, individual and group medical practices, hospitals and other qualified medical organizations that specialize in occupational medicine services. NDI employs its buying power to negotiate with these providers rates that are almost always lower than those paid by clients prior to affiliation with NDI.

NDI coordinates services via the Preferred Provider Network (PPN) whenever possible to ensure the consistency and quality of services on local, regional and national levels. PPN enables NDI to pass on its preferred rates to clients who would normally pay more for the same services if contracted individually.

Providers must complete a formal review of all necessary certification and relevant documentation before gaining acceptance into PPN. Upon approving a partner, NDI obtains copies of all required training certifications and any other necessary documentation to support its service capabilities. NDI maintains all provider information in a database and stores all documentation in its filing system.
