El Mirage, Arizona

A fully equipped, freestanding emergency room — not an urgent care.

Walk in with chest pain, a bad fall, trouble breathing, a high fever, or an injury that cannot wait. You are always seen by a board-certified physician — 24/7/365, with CT, X-ray and a full lab in the building. No appointment and no referral.

Call (480) 237-4922 Get Directions

Open 24 hours a day, 7 days a week, 365 days a year. No appointment and no referral.

Come in now

You are already at the right place. Walk in any hour — no appointment and no referral needed.

Call 911 instead if you cannot travel safely, or if symptoms are severe or getting worse quickly.

What brings people in

If you can see yourself on this list, come in. If you cannot and something still feels wrong, come in anyway.

Heart, breathing and stroke

Chest pain or pressure — Including pain spreading to the arm, jaw or back, or breathlessness with it. Do not wait to see whether it passes — call 911.

Stroke signs — Sudden weakness, drooping on one side, confusion, or trouble speaking or understanding. Call 911, not a car — treatment can start in the ambulance.

Trouble breathing — Asthma, a chest infection, or breathlessness you cannot account for. If someone cannot finish a sentence, call 911.

Injuries, falls and head knocks

Injuries, fractures and deep cuts — If you cannot put weight on it, it looks the wrong shape, or the bleeding will not stop, come in. How much it hurts does not tell you whether it is broken.

Head injury — Come in even feeling fine if you take a blood thinner — including aspirin. A bleed can declare itself hours later.

A seizure — Call 911 for a first seizure in anyone, for a seizure that does not stop, or if the person does not come round properly afterwards. Come in after any seizure that is new or different from the usual pattern.

Heat, dehydration and desert stings

Heat illness — Confusion, stopping sweating, or not improving out of the heat. Heat stroke is a 911 call and minutes matter.

Dehydration — When drinking is no longer keeping up — dizziness on standing, very little urine, or a child who will not take fluids.

Scorpion stings — Most are painful and settle. Come in for a young child, for drooling or difficulty swallowing, or for muscle jerking.

Rattlesnake bites — Always an emergency, even when the bite looks minor and hurts little. Call 911 and do not apply ice or a tourniquet.

Children, fever and sudden pain

High fever, or fever in an infant — Any fever under three months old should be seen the same day. At any age, a rash that does not fade when pressed is a 911 call.

Allergic reaction — Swelling of the lips or throat, or any trouble breathing, is a 911 call. Use your own adrenaline injector first if you have one.

Severe or sudden abdominal pain — Especially with fever, persistent vomiting, or pain that arrived in minutes rather than hours.

When you are not sure, or not safe

Thoughts of harming yourself, or not feeling safe — Call or text 988 first — free, confidential and staffed around the clock. You can also walk in: we treat and stabilise you here, and if you need psychiatric admission or specialist crisis care we arrange the transfer.

Not sure, and worried — Come in, or call and describe it on (480) 237-4922. You are not expected to diagnose yourself and you are not wasting our time.

The difference is the building

Open now

24 hours a day, 7 days a week, 365 days a year.

Walk in

No appointment. No referral. Ever.

A physician sees you

You are seen by a board-certified physician, every visit, at every hour.

Answers here

CT, X-ray and a full laboratory on site — plus a critical care room. Ultrasound is called in from a mobile service.

An urgent care that suspects something serious must send you on to start again. Everything needed to find out is already here.

What we treat

Everything we treat →

Chest Pain & Stroke Symptoms

Chest pressure, pain spreading to the arm or jaw, sudden weakness, drooping on one side, or trouble speaking. These are the ones not to wait on — come straight in, or call 911 if you cannot travel safely.

What to expect →

Injuries, Fractures & Burns

Falls, breaks and sprains, deep cuts, and burns. CT and X-ray are here in the building, so you get answers during your visit instead of a referral for imaging somewhere else.

What to expect →

Breathing Problems & Severe Infections

Asthma attacks, pneumonia, high fever, severe abdominal pain, dehydration, and allergic reactions — for adults and children alike.

What to expect →

Not Sure If It Is an Emergency?

Then come in — that is reason enough, and nobody should have to diagnose themselves first. See what a full-scope emergency room has on site, and what a visit costs.

What to expect →

How long you will be here

There are wait times. Any emergency room that tells you otherwise is selling something. What we can tell you is what our own records show:

Under 30 min

The average time from arriving to being seen has stayed under 30 minutes year round.

About 1.5 hrs

From walking in to walking out, on our own records. Any individual visit can run longer.

And if someone arrives sicker than you, they go first. That is how an emergency room is supposed to work, and it is why any individual visit can run longer than an average.

What competes for your turn

Here

Other emergency patients.

At a hospital emergency department

Emergency patients, plus inpatient admissions and ambulance traffic.

No inpatient hospital attached, so you are not waiting behind patients who need a bed upstairs.

Not absorbing ambulance diversions from a regional trauma catchment.

One department, not a campus — park at the door rather than navigating a hospital.

Everyone here is an emergency patient. No clinic schedule competing for the same physician.

None of that is a promise about your visit. It is a difference in how the two models are organised, and it is checkable from the outside.

We are an emergency room, not a hospital

We treat and stabilise you here. If you need to be admitted, or need hospital-level inpatient care, we arrange the transfer to a hospital.

Most visits end with people going home. When a visit needs to end in a hospital bed, getting you there is part of what we do.

We are not a pediatric emergency room, and we treat children every day. El Mirage and the cities around it have a lot of young families.

No surprise bills

We do not balance bill. Ever — any patient, any insurer.

You will never pay more than your in-network deductible and coinsurance.

An Explanation of Benefits is not a bill.

No insurance? You are assessed and screened all the same — what you can pay never decides your care.

How billing works

In partnership with HealthPass

The bill is the part people dread. This is what we did about it.

HealthPass is a healthcare membership — not insurance. It pays the copays, deductibles and coinsurance your insurer assigns for eligible visits to this emergency room, and it applies to visits you have already had, not only the ones ahead of you.

Visits already behind you

An eligible visit you have already made can be paid for. That is unusual, and it is the part worth knowing if a bill has already arrived.

The visit in front of you

Come in first and sort the money afterwards. Nobody is turned away, and no cost question is settled at the door.

And the ones after that

Membership keeps paying those costs for future eligible visits here, so the next emergency is not also a calculation.

HealthPass is a separate company and it is not insurance. It is a membership that works alongside the insurance you already have — never in place of it. You do not need it to be seen here; our doors work the same either way. What it covers, the price and the sign-up all live on their own site, because the product should make its own claims.

In-network benefits honored. No balance billing.

We honor in-network insurance benefits for emergency care, and we do not balance bill patients for emergency care they have received. An Explanation of Benefits from your insurer is not a bill — if anything you receive is unclear, call our billing team and we will walk you through it.

About your bill, before you worry about it

If something arrives from your insurance company after your visit, it is almost certainly not a bill. It is an Explanation of Benefits — a statement of what they paid. The large number on it is not what you owe.

For emergency care, federal law limits your share to the ordinary in-network copay, coinsurance and deductible your plan already sets. We do not bill you for the difference, and we never will.

If anything you receive is unclear, call us before you pay it. Our billing team would rather explain a statement than have you pay something you do not owe.
