Emergency department (ED) patients may be billed for critical care time (current procedural terminology codes 99291 and 99292) if they receive at least 30 min of critical care services. We sought to determine the median cash (self-pay) prices for critical care time performed in the ED in the United States and assess for associations between hospital characteristics and prices.

We performed a cross-sectional analysis of hospital cash prices for critical care time performed in the ED using the first 25 alphabetical states. For each hospital, we recorded hospital characteristics including state, control (nonprofit, governmental, or for-profit), size, teaching status, and system. We then searched for each hospital's cash prices for 99291 and 99292 using Turquoise and hospital websites. We determined the median price for 99291 nationally, regionally, and for large hospital systems. We performed multivariable quantile regression to assess for associations between hospital characteristics and prices for 99291.

Of the 2629 eligible hospitals, 2245 (85.4%) and 1893 (72.0%) reported cash prices for 99291 and 99292, respectively. For 99291, the cash price ranged from $45 to $84,775 with a median of $1816 (IQR: $1039-3237). For 99292, the median price was $567 (IQR: $298–1008). On multivariable analysis, hospitals had higher cash prices for 99291 if they were located in the West, for-profit, or part of a large system. In particular, hospitals owned by Tenet Healthcare charged the most for 99291 (median $28,244).

The cash prices for critical care time vary substantially based on hospital characteristics. In particular, for-profit hospitals and those in the West tend to charge the most. Given that patients who require critical care are unlikely to be able to choose the hospital to which they present, standardization of critical care time fees should be considered.
