Columbia/HCA Healthcare Corporation was a major American healthcare company formed in 1993 through the merger of Columbia Healthcare Corporation and HCA Healthcare. It operated numerous hospitals and healthcare facilities across the United States, focusing on providing a wide range of medical services to communities. The company gained attention in the late 1990s due to allegations of fraudulent billing practices and other legal issues. In 2000, Columbia/HCA agreed to pay a significant settlement to resolve these allegations, leading to a rebranding and restructuring of the organization. Today, it is known simply as HCA Healthcare.
