An average ER visit costs $1,500–$3,000+ in facility fees alone. Urgent care averages $100–$200 total. The wrong choice costs thousands. Freestanding ERs are the most dangerous trap—they look like urgent care but charge ER prices, and BillKarma finds freestanding ER patients pay an average of $2,400 more than hospital ER patients for identical conditions.
1. Cost comparison: ER vs. urgent care vs. retail clinic
| Setting | Avg Total Cost | Avg Insurance Copay | Physician Bill Separate? | Wait Time |
|---|---|---|---|---|
| Hospital emergency room | $1,500–$3,500+ | $150–$300 | Yes (usually) | 1–4+ hours |
| Freestanding emergency room | $1,500–$3,500+ | $150–$300 (if in-network) | Yes | Shorter than hospital ER |
| Urgent care center | $100–$250 | $25–$75 | No (one bill) | 15–60 minutes |
| MinuteClinic / retail clinic | $70–$150 | $15–$40 | No | 15–45 minutes |
| Telehealth visit | $50–$100 | $10–$40 | No | Minutes |
| Primary care office visit | $100–$200 | $20–$50 | No | Next available appt |
2. When to go to the ER
The ER is the right choice when a delay in care could result in serious harm. Go to the ER for:
- Chest pain or pressure (assume cardiac until proven otherwise)
- Difficulty breathing or shortness of breath at rest
- Stroke symptoms: sudden facial drooping, arm weakness, slurred speech, sudden severe headache (“worst headache of my life”)
- Major trauma: car accidents, falls from height, severe lacerations, suspected fractures with deformity
- Altered consciousness or confusion
- Uncontrolled bleeding that pressure won’t stop
- Severe allergic reactions with throat swelling, difficulty swallowing, or hives with breathing changes
- Severe abdominal pain, especially with rigidity, vomiting blood, or rectal bleeding
- Suspected poisoning or overdose
- Suicidal ideation with plan or intent
When in doubt, call 911 or your physician. If you have to ask “should I call 911?”—call 911.
3. When urgent care is appropriate
Urgent care handles conditions that need attention today but aren’t life-threatening:
- Ear infections, sinus infections, strep throat
- Urinary tract infections (uncomplicated)
- Minor cuts requiring stitches (wound is controlled)
- Sprains and strains (when there’s no obvious bone deformity)
- X-rays for suspected minor fractures (non-displaced)
- Flu symptoms, fever (adults without major comorbidities)
- Mild asthma flare (if you have rescue inhaler and are improving)
- Skin rashes, minor burns, insect bites
- STI testing, pregnancy tests
- COVID-19 testing and treatment
UTI: urgent care vs. ER cost comparison
A patient with classic UTI symptoms (frequency, burning, no fever, no back pain) went to the ER because it was late on a Sunday. Her bill: $2,340 facility fee + $280 physician fee = $2,620 before insurance. Her copay was $300. The same condition treated at an urgent care center down the street would have cost $140 total, with a $40 copay. Cost of going to the wrong setting: $260 in extra out-of-pocket and $2,480 in extra system cost.
4. Freestanding ERs: the most expensive trap
A freestanding emergency room (FSER) is a state-licensed emergency room that is not physically connected to a hospital. They are designed to look like urgent care centers—clean, fast, and easy to park at. But they charge hospital ER prices.
| Feature | Hospital ER | Freestanding ER | Urgent Care |
|---|---|---|---|
| Facility fee | $1,500–$3,500+ | $1,500–$3,500+ | $0 (one bundled charge) |
| E&M billing codes | 99281–99285 | 99281–99285 | 99202–99215 |
| Physician bill separate | Usually yes | Usually yes | No |
| Subject to EMTALA | Yes | Sometimes (state-dependent) | No |
| In-network (typical) | Often yes | Often not | Varies |
| Can treat life threats | Yes | Limited (must transfer) | No |
BillKarma finding: freestanding ER patients pay an average of $2,400 more than hospital-based ER patients for the same presenting conditions. Part of this is due to higher rates of out-of-network status at FSERs. Part is due to facility fees charged at ER rates for conditions that urgent care could have handled at a fraction of the cost.
How to spot a freestanding ER: Look for the words “Emergency Room,” “Emergency Center,” or “Emergency Care” on the sign. “Urgent Care,” “Clinic,” or “Walk-In Care” indicates a lower-cost setting. If you’re not sure, ask at the front desk: “Are you a freestanding ER or an urgent care center?” and “Are you in-network with my insurance?” before checking in.
5. How insurance treats ER visits differently
Your insurance plan likely applies different cost-sharing rules to ER visits than to other care:
- ER copay (not waived if not admitted): Most plans charge an ER copay of $150–$300. Some plans waive the ER copay if you’re admitted to the hospital. If you visit the ER and are sent home, the copay usually applies in full.
- “True emergency” requirements: Some plans have provisions to charge higher cost-sharing if they determine the ER visit wasn’t a “true emergency.” This is legally complex—the Prudent Layperson Standard (adopted in most states and federal law) defines an emergency as a condition that a reasonable layperson would believe requires immediate attention. Insurers cannot retroactively penalize you for a good-faith ER visit that turned out to be minor.
- Out-of-network ERs: Under the No Surprises Act, you cannot be charged more than in-network cost-sharing for emergency services at any ER, even if the hospital is out-of-network. This does not apply to freestanding ERs in all states.
- Separate deductibles: Some plans (especially grandfathered plans and some HMOs) have a separate ER deductible in addition to the general deductible. Read your Summary of Benefits.
6. EMTALA: your right to emergency care
The Emergency Medical Treatment and Labor Act (EMTALA), enacted in 1986, gives every person the right to:
- A medical screening examination at any Medicare-participating hospital ER, regardless of ability to pay, insurance status, or immigration status
- Stabilizing treatment for any emergency medical condition identified in the screening
- Safe transfer to another facility, if needed, once stabilized
What EMTALA does not do: It does not forgive your bill. After the emergency is stabilized, the hospital can and will bill you. It does not apply to freestanding ERs in states that haven’t extended EMTALA to them. It does not guarantee ongoing care beyond stabilization.
If you are turned away or denied a screening exam at a hospital ER, you can file an EMTALA complaint with the CMS regional office. Hospitals found in violation face significant fines and can lose Medicare participation.
7. ER vs. urgent care billing codes
The billing code used by the provider is the single most important determinant of how much you’re charged. Here’s how they differ:
| Code | Setting | Acuity Level | Medicare Rate (Professional) |
|---|---|---|---|
| 99281 | ER | Minor (minimal evaluation) | ~$26 |
| 99282 | ER | Low acuity | ~$52 |
| 99283 | ER | Moderate acuity | ~$101 |
| 99284 | ER | High acuity | ~$174 |
| 99285 | ER | Highest acuity (usually with decision-making) | ~$239 |
| 99202–99203 | Clinic / urgent care | Low complexity | ~$73–$112 |
| 99204–99205 | Clinic / urgent care | Moderate-high complexity | ~$153–$218 |
| 99213–99215 | Clinic / urgent care (established) | Low-high complexity | ~$93–$208 |
The facility fee is separate from these E&M codes. The E&M code captures the physician’s professional work. The hospital charges a separate facility fee (its own E&M-equivalent scale: Level 1–5 for ERs) that typically costs far more than the physician fee. At urgent care, there is no separate facility fee—the clinic charges one bill that covers both the physician and the facility.
8. Surprise billing in the ER
Even if your hospital is in-network, you may receive an out-of-network bill from the ER physician. This happens because hospitals contract with physician staffing companies (like Envision, TeamHealth) that negotiate their own contracts—sometimes separate from the hospital’s insurance contracts.
The No Surprises Act (effective 2022) protects you:
- For emergency services, you cannot be charged more than your in-network cost-sharing amount, even if the ER physician is out-of-network
- The OON provider and insurer must settle billing disputes through arbitration—you are not involved in or responsible for that dispute
- You must receive a notice (required by law) if any provider involved in your care is OON
- After the emergency is stabilized, you can consent to ongoing OON care—but the surprise billing protections only continue if you do not sign the OON consent form
If you receive a surprise bill from an ER physician: Do not pay it at the OON rate. Call your insurer and tell them you received an OON bill for emergency services. They must process it at in-network cost-sharing under the No Surprises Act. If they refuse, file a complaint at cms.gov/nosurprises.

How much does an ER visit cost vs. urgent care?
ER visits cost $1,500–$3,500+ in facility fees alone, plus a separate physician bill. Urgent care averages $100–$200 total (one bill). After insurance, ER copays run $150–$300 vs. $25–$75 at urgent care. For non-emergency conditions, urgent care costs 5–15 times less.
What is a freestanding ER?
A freestanding ER is a state-licensed emergency room not connected to a hospital. It charges ER-level facility fees ($1,500–$3,500+) but often isn’t in-network with major insurers. BillKarma finds freestanding ER patients pay an average of $2,400 more than hospital ER patients for identical conditions. Check the sign before entering and always confirm in-network status.
Can the ER bill me if I can’t afford to pay?
Yes. EMTALA requires the ER to treat you regardless of ability to pay, but it does not forgive the bill. After treatment, apply for the hospital’s financial assistance (charity care) program. Nonprofit hospitals are required to have these programs and must help patients who meet income thresholds. See our financial assistance guide.
Does the No Surprises Act protect me from OON ER bills?
Yes. For emergency services, you can only be charged in-network cost-sharing, even if the ER physician is OON. If you receive an OON bill for emergency care, call your insurer and report it. Do not pay at the OON rate. You can also file a complaint at cms.gov/nosurprises.
What is the cheapest option for non-emergency care?
Telehealth is typically cheapest at $10–$40 after insurance. Retail clinics (MinuteClinic, CVS Health, etc.) run $15–$40 copay and handle minor conditions quickly. Urgent care ($25–$75 copay) handles conditions requiring a physical exam, X-rays, or minor procedures. Save the ER for genuine emergencies.
