Interoperability vendor NextGen Healthcare Inc. (Nasdaq: NXGN) will apply to become a Qualified Health Information Network (QHIN) under the Trusted Exchange Framework and Common Agreement (TEFCA). Large national networks such as the CommonWell Health Alliance and eHealth Exchange have expressed their intention to apply to become QHINs, as has the EHR giant Epic Systems. Another company called Health Gorilla has said it intends to go through the formal application process. NextGen says it supports more than 100,000 providers with its ambulatory electronic health records (EHR) and practice management (PM) solutions, as well as one-third of health information exchanges (HIEs) across the country, with interoperability tools. The company is the first ambulatory-focused solutions provider to announce its intention to become a QHIN.
