San Francisco-based Practice Fusion, which offers providers free electronic medical records software and patient management tools, has added another $15 million to its coffers, bringing its latest round of funding up to $85 million. Qualcomm Life Fund led the round with participation from new backer Longitude Capital and returning Practice Fusion investors Artis Ventures, Industry Ventures and Band of Angels. The company has now raised almost $150 million total.

Practice Fusion plans to use the funds to roll out new products and features in 2014, including new population health tools for providers that will enable them to better "proactively manage patient care" for their entire patient population as well as a newly expanded API offering to developers that includes integration with health devices.

In 2013 Practice Fusion says it has grown its employee count to north of 300; opened offices in Seattle and Palo Alto; helped facilitate 55 million patient visits across the US (mostly for small practices); launched its appointment booking and review site Patient Fusion; launched its data analytics offering, Insights; and added APIs that helped connect 15 partners to the platform, including billing and imaging APIs.

“Practice Fusion doctors have facilitated six percent of all patient visits in the US this year. This huge reach makes us the front-running health technology company, and we’re going to double that reach next year,” said Ryan Howard, CEO, Practice Fusion said in a statement.
