MercyOne (formerly Mercy Health Network) is an American non-profit system of Catholic^[2] hospitals, clinics, and health care facilities in the U.S. states of Iowa,^[3] Nebraska and surrounding communities. It is owned and operated by Trinity Health, since 2022.^[4] Previously, it was run under a joint operating agreement between Trinity Health and Catholic Health Initiatives (now CommonSpirit Health).^[5]

History

In 2016, the health system announced plans for a $500 million renovation at MercyOne Des Moines Medical Center in downtown Des Moines. The project is expected to take five to eight years and include a new 11-story hospital tower as well as power plant.^[6]^[7]

Bob Ritz was appointed company president and CEO, effective July 1, 2017.^[8]

In 2019, the company changed its name from Mercy Health Network to MercyOne, and rebranded its 450 locations.^[9]

In 2020, an employee improperly accessed patient information; the data breach resulted in a class-action lawsuit settled by the company in 2024 for $1.8 million.^[10]^[11]

Trinity Health acquired CommonSpirit Health's 50% stake in MercyOne in September 2022.^[4]

MercyOne merged with Genesis Health System in March 2023.^[12]^[13]

In 2024, the MercyOne health network comprises over 40 hospitals and more than 230 health care facilities.^[1]
