At a glance
In our analysis of reviewed ER bills
Short, quotable observations based on bill reviews completed through Check My ER Bill.
- In our analysis, hospital facility fees were the single largest line item on most ER bills, often $1,500–$3,500 or more.
- In our analysis, duplicate or repeated lab and monitoring charges were among the most commonly questioned items.
- In our analysis, vague "misc supplies" or "ER kit" lines were one of the most difficult charges for patients to verify.
- In our analysis, a single ER visit frequently produced two or three separate bills from the hospital, ER physician group, and radiologist.
- In our analysis, imaging charges (X-ray, CT, ultrasound) were often the largest non-facility line on the bill.
- In our analysis, facility fees coded at Level 4 or 5 sometimes appeared on short, low-complexity visits — a pattern worth questioning.

What this means
Plain-English explanations
A closer explanation of what each finding may mean when someone is reading an itemized ER bill.
42% of ER bills reviewed had at least one duplicate or very similar charge.
In reviewing ER bills, we found that about 42% included duplicate or very similar charges. These are not always errors, but they are one of the most common things people choose to double-check with the hospital or insurer.
The average ER facility fee ranged from $1,800 to $2,600 on reviewed bills.
ER facility fees are charged by the hospital for using the emergency department, separate from physician, lab, or imaging charges. In reviewed bills, the average facility fee ranged from $1,800 to $2,600, making it one of the most important lines to understand.
1 in 3 ER bills reviewed included a vague “supply” or “misc” charge.
Vague supply charges are difficult for patients to evaluate because the description often does not explain what was used. In our reviewed bills, about 1 in 3 included a “supply,” “kit,” or “misc” charge that may be worth asking about.

Deep dive
What shows up inside reviewed ER bills
A closer look at the patterns patients most often need help understanding.
Duplicate Charges
42% of ER bills reviewed had at least one duplicate or very similar charge.
These often show up as the same lab, supply, or monitoring line appearing more than once on the same date.
Why it matters: Repeated charges are easy to miss on a summary bill, but they are among the clearest items to ask about.
Facility Fees
The average ER facility fee ranged from $1,800 to $2,600 on reviewed bills.
A facility fee is charged by the hospital for using the emergency department, separate from doctor, lab, or imaging charges.
Why it matters: It is often the largest line item and one of the hardest charges for patients to understand.
Vague Charges
1 in 3 ER bills reviewed included a vague “supply” or “misc” charge.
These lines may be labeled as supplies, kits, or miscellaneous medical items without a clear description.
Why it matters: Patients need enough detail to know what was used and whether the charge belongs on the bill.
Imaging Costs
Imaging charges were often among the highest non-facility items on reviewed ER bills.
X-rays, CT scans, and related reading fees can appear as separate charges from the hospital and radiology group.
Why it matters: Imaging prices vary widely, so unusually high lines are worth comparing and asking about.
Multi-Provider Billing
Most reviewed ER bills included charges from more than one provider.
A single ER visit can produce bills from the hospital, ER physician group, radiologist, or lab.
Why it matters: Multiple bills make it harder for patients to understand the true cost of one visit.
