Denver Health’s Pediatric Emergency Department and Urgent Care is here for you and your child when the unexpected happens.
When you bring your child to Denver Health's Pediatric Emergency Department and Urgent Care for care, you and your child will have a separate waiting area that is pediatric-specific. With a waiting room separate from the Adult Emergency Department entrance, you’ll find a child-friendly environment that won’t be overwhelming when kids need care.
We understand the special needs and concerns that come up for parents and caregivers. Cuts, unexplained swelling, and broken bones need treatment right away. All our doctors have pediatric training in treating children from infants to late teenagers.
Pediatric urgent care treats illnesses and injuries that require medical attention, usually after hours or at night, when your regular pediatrician may not be available. The pediatric emergency department treats a child's life-threatening injuries such as head injuries, serious broken bones, and injuries and illnesses that usually need treatment immediately. We offer both levels of care 24 hours a day.
If your child's condition requires inpatient services, we have an inpatient unit with a pediatric intensive care unit close by.
Call Denver Health's free NurseLine at 303-739-1211 if you have any immediate questions and guidance.
Get the advice and help you need 24 hours a day for FREE with Denver Health Connect 2 Care.
Just call 303-602-2273 (CARE) and Denver Health will connect you with nurses and doctors who can provide you medical help, schedule urgent visits and in some cases, prescribe medicine over the phone. Plus, if your child needs care right away, they can let the Pediatric ER experts know that you are on your way. Call anytime to get connected to the right answers.
