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 – connected or enrolled. 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 enroll and connect new organizations to the Mass HIway each day.
