The LDS Church does not own Intermountain Health. The below paragraph is from the Intermountain Healthcare website.
History of Intermountain Health
Intermountain Health operations in Utah were first established in the early 1900s with the building of hospitals with funding and leadership like W.H. Groves Latter-day Saints Hospital (now LDS Hospital), the building of the Thomas D. Dee Memorial Hospital by Annie Taylor Dee (now McKay-Dee Hospital), Primary Children’s Hospital and others which ultimately became part of the Church of Jesus Christ of Latter-day Saints health system. The Church maintained operations, until 1975, when it donated the then 15-hospital system to the communities it served, and Intermountain Health was formed as we know it today.
