There are two medical centers that bear the UCLA name, but are not operated by UCLA: [[Harbor–UCLA Medical Center]] and [[Olive View–UCLA Medical Center]]. They are actually [[Los Angeles County, California|Los Angeles County]]-operated facilities that UCLA uses as [[teaching hospital]]s.

Each medical center serves as the primary teaching site for that campus's medical school. UCSF is perennially among the top five programs in both research and primary care, and both UCLA and UC San Diego consistently rank among the top fifteen research schools, according to annual rankings published by ''[[U.S. News & World Report]]''.<ref>{{cite web |url=http://grad-schools.usnews.rankingsandreviews.com/best-graduate-schools/top-medical-schools |title=2013 Best Medical Schools |year=2012 |work=[[U.S. News & World Report]] |access-date=August 19, 2012 |archive-date=February 22, 2017 |archive-url=https://web.archive.org/web/20170222164609/http://grad-schools.usnews.rankingsandreviews.com/best-graduate-schools/top-medical-schools |url-status=dead }}</ref> The teaching hospitals affiliated with each school are also highly regarded – the [[UCSF Medical Center]] was ranked the number one hospital in California and number 5 in the country by ''U.S. News & World Report''{{'}}s 2017 Honor Roll for Best Hospitals in the United States.<ref>{{cite web |url=http://health.usnews.com/health-news/best-hospitals/articles/2010/07/14/best-hospitals-2010-11-the-honor-roll.html |title=U.S. News Best Hospitals 2012–13: the Honor Roll |last1=Comarow |first1=Avery |date=July 16, 2012 |work=[[U.S. News & World Report]] |access-date=August 19, 2012 |archive-date=October 10, 2010 |archive-url=https://web.archive.org/web/20101010191637/http://health.usnews.com/health-news/best-hospitals/articles/2010/07/14/best-hospitals-2010-11-the-honor-roll.html |url-status=live }}</ref> UC also has a sixth medical school—[[UC Riverside School of Medicine]], the only one in the UC system without its own hospital.

In the latter half of the 20th century, the UC hospitals became the cores of full-fledged regional health systems; they were gradually supplemented by many outpatient clinics, offices, and institutes. Three UC hospitals are actually county hospitals that were sold to UC, which means that UC currently plays a major role in providing healthcare to the indigent. The medical hospitals operated by UC Irvine (acquired in 1976), UC Davis (acquired in 1978), and UC San Diego (acquired in 1984) each began as the respective county hospitals of [[Orange County, California|Orange County]], [[Sacramento County, California|Sacramento County]], and [[San Diego County, California|San Diego County]]. As of 2025, UC medical centers handle each year about 10.8 million outpatient visits, 474,000 emergency room visits, and roughly 1.32 million inpatient days.<ref name="At a glance" />
