Since its launch in October 2012, numerous organizations have enrolled with The Mass HIway. The HIway Status Tracker tool below shows participating healthcare organizations by their status – in-progress, connected or transacting. Participating organizations range from large hospitals to small practices and include, among others, behavioral health, long-term/post-acute care, home health, acute care and ambulatory care organizations. Collectively, these organizations are responsible for millions of Mass HIway transactions. EOHHS' HIway Operations continues to on-board and connect new organizations to the Mass HIway each day.
