as a public company in 1992. In February 1994, HCA Healthcare merged with Louisville, Kentucky-based Columbia Hospital Corporation, which earlier had acquired 73 hospitals of Galen Health Care from Humana, to form Columbia/HCA. Related names of note include HCA International and Health Corporation of America. Columbia Hospital Corporation In 1988, Rick Scott and Richard Rainwater each put up $125,000 in working capital in their new company, Columbia Hospital Corporation; they borrowed the remaining money needed to purchase two struggling hospitals in El Paso for $60 million. Then they acquired a neighboring hospital and shut it down. Within a year, the remaining two were doing much better. By the end of 1989, Columbia Hospital Corporation owned four hospitals with a total of 833 beds. In 1992, Columbia made a stock purchase of Basic American Medical, which owned eight hospitals, primarily in southwestern Florida. In September 1993, Columbia did another stock purchase, worth $3.4 billion, of Galen Healthcare, which had been spun off by Humana Inc. several months earlier. At the time, Galen had approximately 90 hospitals. After the purchase, Galen stockholders had 82% of the stock in the combined company, with Scott still running the company.

Frist, Jr. The total transaction was valued at approximately $33 billion, making it the largest leveraged buyout in history at the time, eclipsing the 1989 buyout of RJR Nabisco. In May 2010, HCA announced that the corporation would once again go public with an expected $4.6-billion IPO as HCA Holdings, Inc. In March 2011, HCA sold 126.2 million shares for $30 each, raising about $3.79 billion, at that time, the largest private-equity backed IPO in U.S. history.

In December 2018, a historical marker was installed in the parking lot of HCA's Sarah Cannon Cancer Center in Nashville, formerly the location of HCA's first hospital, Park View Hospital. In 2018, the company was ranked No. 67 in the 2019 Fortune 500 list of the largest United States corporations by total revenue.
