National Imaging Associates

National Imaging Associates is a U.S. healthcare services company focused on specialty benefit management and prior authorization, historically best known for radiology benefits management. Founded in 1995, it built clinical and technology-enabled programs to help health plans manage the quality, appropriateness, and cost of advanced imaging and other specialty services. Over time, its scope expanded beyond imaging into areas such as cardiac, musculoskeletal, physical medicine, genetics, and radiation oncology utilization management. The business was acquired as part of the NIA/Magellan Specialty Health asset transaction announced by Evolent in 2022 and has since been rebranded under Evolent, with the former NIA provider portal continuing as RadMD. For a biotech or healthcare analyst, this is not a drug-development company but a commercial healthcare management organization embedded in payer-provider workflow.
