Where you go inside San Francisco, CA counts as much as which plan you have: San Francisco's median ($1,413) runs 2.2× Oakland's ($633).

San Francisco, CA Emergency Room Visit prices by facility

All prices below come from hospital chargemasters — the official price lists each hospital must publish under federal law. Gross charge is the undiscounted list price; cash price is the self-pay rate; negotiated range covers the spread across insurance contracts.

How we calculate "Your Price" — We prioritize the most actionable price in this order:
  1. Cash price — the self-pay rate you can actually negotiate and pay
  2. Negotiated rate — if reported by the hospital across insurance contracts
  3. Gross charge — fallback only; this is the inflated list price few people pay

This reflects the real prices patients encounter — not inflated chargemaster rates.

# Facility City Your Price vs Median Gross Charge
#1 John Muir Health Walnut Creek, CA $454 -$154 $1,010–$15,134
#2 John Muir Health Concord, CA $454 -$154 $1,010–$15,134

How to choose a lower-cost facility

  • Choose independent outpatient centers when possible — freestanding ASCs (ambulatory surgical centers) consistently charge less than hospital outpatient departments for identical procedures.
  • Ask for the cash price if your deductible isn't met — self-pay rates are often lower than what insurance pays before your deductible is satisfied, especially at facilities that have a high cash-price discount.
  • Avoid hospital outpatient departments for routine cases — hospital-owned locations add a facility fee that freestanding centers don't charge, often adding $500–$1,500 to the same procedure.
Important: Many procedures are done at ambulatory surgical centers (ASCs) that are often 30–60% cheaper than hospital outpatient departments with the same clinical quality. Most ASCs are not in this hospital dataset — meaning your cheapest option may not even appear here. Ask your doctor if the procedure can be done at a freestanding ASC.

Most expensive emergency room visit providers in San Francisco, CA

These facilities report the highest prices for this procedure. Academic medical centers and specialty hospitals often top this list — their gross charges rarely reflect what anyone actually pays, but understanding the spread helps you negotiate.

Facility City Price vs Median
Saint Francis Memorial Hospital San Francisco, CA $1,438 +$830
St. Mary's Medical Center - San Francisco San Francisco, CA $1,388 +$780
Alameda Health System Oakland, CA $677 +$69

Why prices vary this much

A small number of hospitals (2) report very high prices above $746, which drives much of the overall price range. Excluding these, most facilities cluster in a significantly tighter band.

Setting drives much of the gap in San Francisco, CA: the median outpatient price is $608 versus $504 inpatient, so where a procedure is performed often matters more than which hospital you choose. Of the San Francisco, CA facilities reporting prices, 3 fall in a low-cost tier (up to $548) while 3 sit in a high-cost tier ($627 and up) — a lower-priced option almost always exists within the same state.

The spread comes from how each hospital sets its chargemaster (the undiscounted list price), what cash discounts it applies, and what rates it negotiates with each insurer. Facility classification matters too — a hospital-owned outpatient center adds a facility fee that a freestanding clinic does not. Understanding these mechanics is the first step to paying less.

How insurance changes what you actually pay

Hospital list prices are only part of the picture. What you pay out of pocket depends on your deductible, your plan's out-of-pocket maximum, whether the facility is in-network, and whether your plan classifies the visit as outpatient or inpatient. A lower gross charge doesn't guarantee a lower bill if the facility is out-of-network or adds facility fees your plan doesn't cover.

What's Actually on Your Emergency Room Visit Bill

A emergency room visit involves multiple providers — each bills separately. Understanding each line item helps you verify your Explanation of Benefits and catch billing errors.

Emergency Department

  • ED Facility Fee — Based on acuity level 1–5. Level 3–4 is most common. Medicare OPPS pays $86–$608 by level.
  • Emergency Physician Professional Fee — Billed separately by EM physician group. Major source of out-of-network bills.
  • Labs (conditional) — Ordered based on clinical presentation. Common: CBC, BMP, troponin.
  • Imaging (if ordered) (conditional) — X-ray, CT, or ultrasound billed separately. Each generates its own set of bills.
  • Medications Pharmacy (conditional)
  • Procedures (conditional) — Laceration repair, splinting, IV placement — each CPT billed separately.

Emergency Room Visit Cost by Type

Which type your doctor orders changes the billing code — and what you pay. Here's how the common types differ.

Level 1 — Minor

A recognized variation that can change the billing code and what you owe. Minor complaint, minimal resources used.

Level 2

A recognized variation that can change the billing code and what you owe.

Level 3 — Moderate

A recognized variation that can change the billing code and what you owe. Most common. Moderate complexity.

Level 4 — High

Level 5 — Critical

A recognized variation that can change the billing code and what you owe. Highest acuity. Full evaluation and high-complexity decision making.

Watch for Separate Bills from These Providers

A emergency room visit involves multiple providers: the facility, the operating physician, and often some ancillary providers. These providers bill independently — and each one may or may not be in your network, even if the facility is.

Action step: Before your procedure, ask the facility coordinator to confirm that all participating providers are in-network on your plan. The No Surprises Act (2022) protects you from unexpected out-of-network bills in many scenarios — but not all. Request a Good Faith Estimate (GFE) if you ask for one.
