Data Sources

Cash-price values are from each facility's latest standard charges file published on its website. The average comparison note uses the city average for the same ER service level: around average means within a +/-10% band, above average means more than 10% above, and below average means more than 10% below. Hospital ownership labels and hospital overall ratings come from the CMS Hospital General Information dataset. CMS ratings are a broad summary, not a perfect measure of whether a hospital is best for a specific service.

Why ER level 4 is the default sort

ERcost defaults to ER level 4 because recent commercial ED spending research shows higher-intensity emergency department visit codes now represent a large share of billed visits. This default is based on the Health Affairs study Price Increases Versus Upcoding As Drivers Of Emergency Department Spending Increases, 2012-19 and its ED spending analysis. By 2019, level 4 was the single most common level among ER levels 3, 4, and 5, with level 5 close behind. Level 4 is a practical default for comparison, but actual coding depends on the care documented for a specific visit.

Hit with a big ER bill in San Francisco Bay Area?

Start by checking the bill for errors, asking about discounts or financial assistance, and using your state's medical-debt rules before you respond to collections.

What you can do now

Request an itemized bill with billing codes, verify that every charge matches the services you actually received, and check whether your bill qualifies for No Surprises Act protections.
Ask the hospital about cash-pay or lump-sum discounts, and apply for financial assistance if you qualify.
Use FAIR Health or Bill Sherlock to check if your ER bill is reasonable.
Use Dollar For to apply for hospital financial assistance at no cost.
Hire a medical billing advocate to review your bill. Most work on contingency, charging only when they successfully reduce what you owe.
Keep every bill, denial, and collection notice. The dates matter if you need to challenge credit reporting, wage garnishment, or a lawsuit filed too late.

California medical-debt rules

Medical-debt credit reporting: State law limits furnishing, reporting, and use of medical-debt information in credit decisions, effective July 1, 2025.
Wage garnishment: More protective than federal. Generally 20% of disposable earnings, with a hardship claim available.
Deadline to sue (statute of limitations): 4 years for written contracts.
