ONC data shows companies that have the largest EHR footprint for eligible professionals
The Office of the National Coordinator for Health Information Technology annually gathers data on which vendors have certified technology used by providers that are participating in the Medicare EHR Incentive Program. This list looks at ambulatory providers and technology reported in 2015. As of July 2016, 632 vendors supply certified health IT to 337,432 ambulatory primary care physicians, medical and surgical specialists, podiatrists, optometrists, dentists and chiropractors participating in the Medicare EHR Incentive Program. Epic Systems, Allscripts, eClinicalWorks, athenahealth and NextGen Healthcare supply 2014 certified technology to 60 percent of all eligible providers that have reported 2014 edition technology.
ONC data is for health IT certified either according to criteria specified for 2014 edition of Health Information Technology Certification, or for HIT certified under the 2011 edition of criteria. Applications certified under either year's criteria can be used to attest to meaningful use.
