In December 2016, Envision and AMSURG merged, and shortly thereafter the company's stock replaced Legg Mason in the S&P 500 index.

[5][6][7] In August 2017, Envision sold its ambulance unit, American Medical Response, for $2.4 billion to KKR, which it subsequently merged with a similar company it had already owned.

[9] In June 2018, KKR announced that it was acquiring the rest of Envision for $9.9 billion, including the assumption or repayment of debt.

[14] Later that October, a U.S. bankruptcy court approved Envision's restructuring plan to split into two companies—Envision Physician Services and AMSURG—the former specializing in staffing doctors to hospital emergency rooms, intensive care units, and birthing suites.

The latter will manage outpatient surgery centers specializing in gastroenterology and orthopedic care.
