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.

See major insurance nurse line numbers

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.
