Carolinas Medical Center-Union has again asked the state to approve a proposed "HealthPlex"--a 21,00 square-foot, $20.4-million emergency care and diagnostic center in Waxhaw, NC. The proposal stalled last year after the N.C. Division of Health Service Regulation declined to issue a certificate of need, saying CMC did not adequately identify the population the HealthPlex would serve and demonstrate need for the facility. CMC's new proposal addresses these issues.
