ZocDoc, makers of an appointment-scheduling mobile app, announced this week a $50 million Series C investment from DST Global, bringing total investment in ZocDoc to $70 million. The company plans to use the funding to expand into new markets and grow its patient and doctor user base.

ZocDoc allows patients to find nearby doctors who accept their insurance, then book appointments, via Android and iOS apps, as well as a web-based interface. The service is free for patients, while doctors pay a $250 monthly fee to fill open appointments.

"Given the well-documented need for change in the healthcare system, both in the U.S. and worldwide, ZocDoc brings much-needed transparency and efficiency to an immense industry that's long been difficult to navigate," stated Yuri Milner, founder of DST Global, in a press release. "We look forward to a future in which ZocDoc is the platform for empowered patients to manage all of their care online."

ZocDoc claims that the service is currently used by nearly 700,000 patients each month, in nine major metropolitan areas.
