Here are the 52 hospitals in America with the most annual emergency room visits for both admitted patients and not admitted patients.
This list is based on data from the American Hospital Directory, which calculates total annual ER patient volume estimates using Medicare claims "total days" and "Medicare days" figures hospitals provided in their most recent CMS cost reports. Data was accessed Feb. 17.
Hospitals marked with an asterisk have provided Becker's with actual ER patient volumes.
Excluding hospitals that have provided Becker's with actual ER patient volumes, figures are rounded to the nearest hundred.
The hospital rankings total 52, although the list includes ties, which means there are more than 52 individual hospitals listed.
