August 4, 2017 - An investor, who purchased shares of Envision Healthcare Corp (NYSE: EVHC), filed a lawsuit in the U.S. District Court for the Middle District of Tennessee over alleged violations of Federal Securities Laws by Envision Healthcare in connection with certain allegedly false and misleading statements made between March 2, 2015 and July 21, 2017.

According to the complaint the plaintiff alleges on behalf of purchasers of Envision Healthcare Corp (NYSE: EVHC) common shares between March 2, 2015 and July 21, 2017, that the defendants violated Federal Securities Laws. More specifically, the plaintiff claims that between March 2, 2015 and July 21, 2017, the defendants made false and/or misleading statements and/or failed to disclose that EmCare routinely arranged for patients who sought treatment at in-network facilities to be treated by out-of-network physicians, that EmCare accordingly billed these patients at higher rates than if the patients had received treatment from in-network physicians, that the Company's statements attributing EmCare's Class Period growth to other factors were therefore false and/or misleading, that Envision's EmCare revenues were likely to be unsustainable after the foregoing conduct came to light, and that as a result of the foregoing, Envision's public statements were materially false and misleading at all relevant times.

On July 24, 2017,it was reported that hospitals associated with Envision Healthcare Corp's subsidiary EmCare were disproportionately likely to engage in surprise billing, in which patients who sought treatment at in-network facilities were treated by out-of-network physicians and subsequently billed at higher rates.
