An industry magazine’s list of top U.S. health care IT companies again shows a heavy Georgia presence.

Healthcare Informatics Magazine lists eight Georgia-based companies in its top 100 health IT companies in 2014, based on revenues from the previous year.

McKesson, based in Alpharetta, is again ranked as the No. 1 company in the industry. The company, with $3.4 million in revenues, has topped the magazine’s list for seven straight years.

Others in the top 100 include Alpharetta-based MedAssets, at No. 17; Greenway Health, based in Carrollton, at No. 32; and HealthPort Technologies, based in Alpharetta, at No. 36.

Other Georgia companies making the list are Lawrenceville-based Brightree, No. 76; Navicure, based in Duluth, No. 79; Surgical Information Systems in Alpharetta, No. 89; and Atlanta-based Craneware at No. 95.

“The metro Atlanta region is recognized as the nation’s health IT capital, consistently delivering some of the most innovative technologies in this sector,” David Hartnett, interim senior vice president of economic development for the Metro Atlanta Chamber, said in a recent statement.

During the years 2008 through 2013, the state’s health IT sector added 17.2 percent more technology workers, according to the Technology Association of Georgia.

“Georgia is at the forefront of the health information technology sector with more than 225 health IT companies based in the state,” said Tino Mantella, TAG president and CEO.

The industry has boomed in Georgia thanks to a mix of homegrown companies and recruitment of out-of-state firms, as well as universities here creating new technologies, TAG told Georgia Health News last year.

Other factors include Atlanta’s large international airport and a friendly business and legislative climate, TAG said.

Companies in the industry offer a range of products and services, from electronic health records, medical billing and revenue management to diagnostics, preserving the security of information exchanges, and consumer health information.

Amanda Shailendra of the Georgia Department of Economic Development added, “With Georgia’s competitive business climate that includes a well-equipped workforce and critical mass of health care IT locations, our state is the ideal location for companies in this industry to grow and expand.”
