Emergency department visit, highest severity
The top-tier ER code — reserved for life- or limb-threatening emergencies requiring extensive testing, multiple specialists, or immediate intervention.
Based on typical US negotiated and cash-pay rates. Hospital charges can run significantly higher — often 2–10x these numbers. If your bill is well above this range, it's worth questioning.
- Assigned when you were discharged home without admission or significant intervention.
- Billed alongside a 'critical care' code (99291) for the same time period.
- Applied for symptoms that resolved with observation and basic medication.
99285 requires documented high-complexity decision-making. If you were sent home within a few hours with minor treatment, this code is almost certainly wrong — dispute it.
