If it might be an emergency, call 911 or go to the nearest emergency department. Our El Mirage emergency room is open every hour of every day and takes walk-ins with no appointment and no referral. If another emergency department is closer to you, that one is the right answer.
Our nearest emergency room to both is the one in El Mirage, and it is open at every hour.

What it is
A freestanding emergency room — a full-scope emergency department to the Arizona standard, not inside a hospital building.
On site: CT, X-ray and a full laboratory, the same equipment list as our Fountain Hills emergency room, so the imaging and blood work that answer most emergency questions happen during the visit.
Which means a patient who needs to be admitted is transferred to a hospital. That is normal, not a failure of the visit, and the time-critical part — assessment, stabilisation, imaging and laboratory work — happens where you walk in. What being admitted involves.
Our emergency rooms treat envenomation and give antivenom, burns, lacerations and tetanus, alongside the ordinary run of an emergency department.
If you look after an older neighbour, these are the two pages
This is the most useful thing on this page and it has nothing to do with which building you come to.
Checking on someone over 65 in a heat wave — what to actually look for, and why the person at risk is often the last to say so.
Your medicine list changes how you handle heat — common medicines change how a body loses heat, and almost nobody is told this by anybody.
Read both before June rather than during it. They are the two pages on this site most likely to prevent a visit rather than direct one.
And when the power goes out, the risk compounds fast if somebody depends on equipment or on air conditioning: what to do, and the carbon monoxide risk from whatever gets used instead.
Drive, or call 911?
Call 911 if it is severe, if the person cannot be moved safely, or if you are not confident you can get them there.
An ambulance is not only transport. Assessment starts in it, and the crew can begin treatment on the way and tell the receiving department what is coming. What happens in the ambulance.
And 911 knows which emergency departments are open right now. If somebody else’s is closer, that is where you should be, and a dispatcher will tell you so.
We are not only for these towns
Our service area is the east and west valley and all surrounding cities. The towns in the title of this page are search engine plumbing, not a boundary — nobody is turned away for living somewhere else, and there is no catchment you have to be inside.
And the reverse holds. If a different emergency department is closer to where you are right now, go to that one. The nearest door is the right door, every time, with no exception for us.
Questions people actually ask
Do I need an appointment or a referral? Neither. Walk in, at any hour.
Is it open overnight, at the weekend, on holidays? Yes. Every hour of every day of the year.
Is it a hospital? No — a freestanding emergency room. Admission means a transfer.
Is there a closer emergency room than yours? Possibly, and if so you should use it. We are not going to guess at the map from here; a dispatcher on 911 knows what is open and where.
What if I am not sure it is an emergency? Come in, or call 911. That is what an assessment is for, and it is not a judgement you have to make correctly on your own first. Which door do you need.
What about cost? Cost is not a barrier to being medically evaluated in our facilities. The bill is a problem for afterwards.

Find your nearest emergency room →About your bill, before you worry about it
Ability to pay is not a barrier to assessment and access to care in our emergency rooms — by law. An emergency visit bills at emergency rates, which are not clinic rates, and we would rather tell you that now than have you find out afterwards.
If anything you receive after a visit is unclear, call the facility you were seen at before you pay it. They hold the record of your visit, and they would rather explain a statement than have you pay something you do not owe.
