Know Where to Go for Care
Choosing between urgent care and the emergency room can be confusing. This guide explains the differences accurately so you can make a confident decision — and know when to call 911.
If you or someone with you may be having a life-threatening emergency, call 911 immediately.
Urgent care is generally intended for mild or non-life-threatening illnesses and injuries, while an emergency room is designed to evaluate serious, severe, rapidly worsening or potentially life-threatening symptoms and has broader emergency diagnostic and treatment capabilities.
Both settings play an important role. The right choice depends on how severe your symptoms are, how quickly they came on, and whether they could be dangerous. Capabilities can vary from one facility to another, so this guide describes general differences rather than absolute rules.
