Freestanding emergency departments (FSED) have seen substantial growth over the past two decades. Research published in the Western Journal of Emergency Medicine states that the National Emergency Department Inventory determined in 2001 that about 1% of all emergency departments (ED) in the United States were FSEDs. Fast forward to 2016 and the Medicare Payment Advisory Commission reported that FSEDs had accounted for 11% of all EDs nationwide. Grand View Research is projecting that the U.S. FSED market size, which was valued at around $3 billion in 2019, is expected to expand at a compound annual growth rate (CAGR) of around 5% from 2020-2027.
