Quick take
- AdventHealth Littleton is the lowest-cost option at $355 - $912 below the state median, just by choosing where you go.
- Ask for the cash price if your deductible isn't met - the median cash price here is $452, and it's often lower than what insurance pays before your deductible is satisfied.
- Freestanding ambulatory surgical centers (ASCs) are often 30-60% cheaper than hospital outpatient departments for the same procedure and may not appear in this hospital-only dataset - ask your doctor if one is an option.
How where you go changes what you pay for emergency room visit
The same emergency room visit bundles different services depending on the setting - facility fee, surgeon fee, and anesthesia each arrive as separate bills. Estimated ranges below reflect the typical full bundled cost, including all expected charges.
- Facility fee $82–$1,365
- Professional fee $17–$832

UCHealth and CommonSpirit Health (formerly SCL Health) dominate the Front Range market, with Centura Health (now Intermountain) adding competition in the Denver corridor. Denver and Boulder wage indices are among the highest in the Mountain West, pushing Medicare-adjusted rates up relative to rural Colorado. The urban-rural price gap in Colorado is one of the widest in the country. Emergency room costs are driven by two separate charges: the facility fee (which varies by ER level, E1–E5) and the physician fee (billed by an independent emergency medicine group). Most patients are unaware that ER physicians are frequently out-of-network even when the hospital itself is in-network - the No Surprises Act limits your liability in this case, but billing disputes still occur. Using an urgent care center for non-emergency conditions typically costs 80–90% less than an ER visit for equivalent care.

Why prices vary - and what it means for your coverage
A small number of hospitals (5) report prices above $751, including HCA HEALTHONE SPALDING REHABILITATION at $1,365, which drives most of the overall spread - excluding them, most facilities cluster in a much tighter band. Setting matters too: the median outpatient price is $438 versus $434 inpatient, so where a procedure happens often matters more than which hospital you pick. Facility fees for emergency care scale with the severity level the hospital assigns your visit, which is why two visits that look similar from the exam table can bill very differently.
None of the prices above are what you'll necessarily owe: your deductible, out-of-pocket maximum, and each provider's network status all still apply.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$868 |
| Deductible met - 20% coinsurance | ~$174 |
| Out-of-network provider | $1,910+ |

Why is an emergency room visit so much cheaper at some Colorado hospitals?

In Colorado, the median cash (self-pay) price is $452 versus a median negotiated rate of $75 - about 6× higher. Asking for the cash price or your insurer's negotiated rate is often the single biggest lever on what you pay.
How much will I actually pay out of pocket for an emergency room visit in Colorado?
Your out-of-pocket cost depends on your deductible, coinsurance, out-of-pocket maximum, and whether the facility is in-network - not just the sticker price. If you have not met your deductible, you will typically pay the negotiated rate in full until you do. Use the CostKits cost forecaster to estimate your specific out-of-pocket amount before you go.

What matters before you schedule
What's on your bill
A emergency room visit involves multiple providers who bill separately - typically ED Facility Fee, Emergency Physician Professional Fee, Labs. Check each line item against your Explanation of Benefits to catch billing errors.
Cost by type
Which type your doctor orders for this emergency room visit changes the billing code, and what you pay. For example: A recognized variation that can change the billing code and what you owe.
Separate bills
A emergency room visit involves the facility, the operating physician, and often ancillary providers - each bills independently, and any one of them may be out-of-network even if the facility isn't. The No Surprises Act limits your exposure in many scenarios, but ask the facility to confirm every participating provider is in-network before your visit.
What to ask before you book
Get the CPT code from your doctor, confirm every provider involved (not just the facility) is in-network, ask for the cash-pay rate if you're uninsured or haven't met your deductible, and request a written estimate for emergency room visit before you schedule.
