If it might be an emergency, call 911 first. Out here that advice is not a formality — distance is the thing that changes the answer. Our Fountain Hills emergency room is open every hour of every day, walk-in, no referral. If another emergency department is closer to you, that one is the right answer.

Our nearest emergency room is in Fountain Hills, and it is open at every hour.

Out here, call 911 earlier than you would in the city

This is the actual point of this page, and it is worth more than the phone number above it.

In a dense part of the valley, driving to an emergency room and calling an ambulance are close to equivalent for a lot of problems. Where distances are longer, they stop being equivalent.

Call 911 rather than driving if:

  • The person is having chest pain, trouble breathing, weakness on one side, difficulty speaking, or a change in how alert they are. These are the ones where minutes have a value and where treatment can begin before arrival.
  • They might lose consciousness. Nobody should be driving themselves, and nobody should be driving a passenger who may collapse.
  • You are not confident you can make the journey — for any reason, including your own state.
  • You would be going alone with a child who is seriously unwell.

An ambulance is not just a ride. The assessment starts in it, treatment can begin on the way, and the receiving department is told what is arriving. What happens in the ambulance.

And a dispatcher decides what to send and where to take you — which may be an emergency department other than ours. That is the correct outcome, not a detour.

Be findable, because it matters more here

Give a location a stranger could act on. Not “past the wash” — the address, the nearest cross streets, a landmark, a mile marker.

Say if there is a gate, and give the code. Say which entrance. Say if the drive is long or unpaved.

Stay on the line if the dispatcher wants you to, and put somebody outside to wave the crew in if there is anyone to spare.

If it happened on a trail, that is its own situation — and when to call 911 on a trail covers what to say, what to do while you wait, and why moving an injured person is usually the wrong instinct.

Check your phone’s emergency SOS and location-sharing settings once, at home, when nothing is happening. Five minutes now, when you are calm and have signal.

What the Fountain Hills emergency room is

A freestanding, full-scope emergency room to the Arizona standard — an emergency department that is not inside a hospital building.

On site: CT, X-ray and a full laboratory, so the imaging and blood work that answer most emergency questions happen during the visit.

A patient who needs to be admitted is transferred to a hospital, which is how these departments work and not a failure of the visit. What that involves.

Our emergency rooms treat envenomation and give antivenom, burns, lacerations and tetanus.

There is also a clinic at the same address — Suite 100, (602) 671-7981 — and it is the only one in our network that takes walk-ins on an urgent care basis. Worth knowing for the things that are not emergencies.

The desert is the hazard profile, and it is close

Rattlesnake bites, scorpion stings and spider bites — each has a correct response, and each of them starts with not trying to treat it yourself.

Heat, and the medicines that change how your body handles it.

And hypothermia — yes, here. Desert nights drop further than visitors expect, and it does not take a mountain.

We are not only for these communities

Our service area is the east and west valley and all surrounding cities. A place name in the title of this page is 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 if a different emergency department is closer to where you are, go to that one. The nearest door is the right door, every time, with no exception for us. How far is too far, in an emergency is the honest version of that question.

Questions people actually ask

Do I need an appointment or a referral? Neither. Walk in, at any hour.

Should I drive or call 911? Out here, lean towards 911 — further than you would in the city. The list above is the short version.

What if I have no cell signal? A phone with no service can still usually reach 911 on any available network. If that fails, get to a landline or to a road where somebody will pass. This is the reason to sort your phone’s emergency settings out before you need them.

Will an ambulance take me to your emergency room? Not necessarily, and you should not ask it to. A dispatcher and a crew take a patient to the department that suits the problem and the timing. That decision is better than a preference.

Is it open overnight and on holidays? Yes — every hour of every day of the year.

What about cost? Cost is not a barrier to being medically evaluated in our facilities. If you arrived by ground ambulance, that bill comes from whoever ran the ambulance and is worth treating as its own question.


Call 911 earlier than you would in town, and be findable when you do. Our Fountain Hills emergency room is open 24 hours a day, every day of the year — walk in, no appointment, no referral. (602) 671-7990. If another emergency department is closer, that one is the right answer. All locations →

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.
