Data Sources: Live wait-time values and recent patient reports are compiled from hospital-published sources, patient submissions, and verified updates. Historical data represents CMS-audited annual performance benchmarks and is not a live estimate of current ER volume. Hospital ownership labels and hospital overall ratings come from the CMS Hospital General Information dataset. CMS ratings are a broad summary, not a perfect measure of whether a hospital is best for a specific service.

Alternatives to the ER

Call 911 or go to the ER for chest pain, stroke symptoms, severe breathing trouble, major injury, severe allergic reaction, or any symptom that may be life-threatening.

For non-emergency symptoms, these options can help you get guidance and decide whether home care, urgent care, or a trip to the ER is the right call.

Call Your Insurer's free 24/7 Nurse Line

Many insurance plans include a free 24/7 nurse line where a registered nurse can help you weigh your symptoms and figure out the right next step.

Use 24/7 Virtual Urgent Care

24/7 virtual urgent care lets you see a provider from home, often in minutes, without waiting room time or an ER bill. Self-pay rates start as low as $59 per visit, and many plans cover it for free.
