Figure 2 graphs the average price paid for care by facility type and year. Between 2012 and 2015, the average price per visit at freestanding EDs increased 54%, from $1,431 to $2,199. During this same period, the average price per visit at hospital-based EDs increased 23%, from $1,842 to $2,259. Prices at urgent care centers were substantially lower and increased only 2% (from $164 to $168) between 2012 and 2015. As prices increased, the amount patients were liable for out of pocket also increased. Freestanding ED patients were liable for 32% out of pocket in 2012 ($462/$1,431) but 35% ($763/$2,199) in 2015. Patients treated in hospital-based EDs were liable for 29% out of pocket in 2012 ($541/$1,842) but 33% ($749/$2,259) in 2015. Even urgent care center patients were liable for more out of pocket over time: 36% in 2012 ($58/$164) versus 38% in 2015 ($63/$168). Median prices by provider type and year are reported in Table E1 (available online at http://www.annemergmed.com). The median prices are lower than mean prices for freestanding and hospital-based EDs, suggesting that payments to these providers are skewed to the right. Changes in mean prices paid out of pocket for freestanding ED patients are greater than the change in median prices, indicating that freestanding ED patients with the highest out-of-pocket costs fared the worst over time.
